eufy 11S MAX Robot Vacuum Cleaner, Super Thin, Quiet | Self-Charging, Easy to use, Cleans Hard Floors to Medium-Pile Carpets, Black

Summary: I read a LOT of reviews about a LOT of products of a similar nature before I leapt in to buy this, my first robot. Overall, this product was good SOLID value for the money. I have now owned it for for OVER a year now, used daily and this analysis is based on close observations during that period. NOT one of those folks who buy it an write a review five minutes after they pull something out of the box. Here are the key points you should consider when buying a Robot to sweep your floors. 1. Price - Look...Price was definitely a consideration at buy in. I studied many models before I bought this one. These kinds of robots overall cost money. $$$. Of course, I am old school. These days some folks buy a Cell phone that cost $500 dollars to $1000 and think nothing of it. To me that is WAY too much. Ditto many models of similar robots. At the time I bought it the robot was on sale so I got a price that was $100 cheaper than competitors whose reviews read about the same as this one did. So the buy in pricewise was a good solid deal that was in what I consider the medium to upper low cost affordability range. Perhaps you would think nothing of spending $850 on a robot. Not me. Like goldilocks, this one was just right. SECRET Costs you may not think about: Some reviews address this, but consider these things as being costs IN ADDITION to buy in: Filters: This thing has a filter. I recall one review whining that filters cost too much. Let me be clear. If you want a new HEPA filter for it every week or two, they will cost you. Me? The filter does not seem to me to very critical since I do not really plan on the robot cleaning my air. It gets dirty and dusty. As a result, I pull it every other use and wash it out under a faucet in my kitchen (a two minute job), let it dry a bit and then put it right back in the machine (Which is super easy to do...no tools or anything - just pull out - click in.) After reading one alarmist review prior to buying, I bought one spare filter at the same time I bought the robot thinking I might find it was true. So far, after a year or more of use, I STILL have not replaced the filter. Just keep using the original. Think about it. Brushes - I bought a kit with spare brushes when I bought the robot. Glad I did. Buy at least one set just to you have them around when you need them. The brushes twirl around and shove cat hair into the maw of the thing as it races around. Somewhere. Somehow, as it toodled about around the six month mark, it threw a brush. (They snap on and off easily) Like a horse throwing a shoe, this is to be expected. This thing runs all over on its own so I could not find where it lost it. To this day I STILL have not found the missing brush. No problem. I just grabbed a spare, snapped it on and it kept on going. Tools - The kit I bought early came with a little cleaning/maintenance tool. See my section on Maintenance below about tools. 2. Utility - Utility to me means ease of use. Based on a year of hard use for my robot you should consider the following lessons learned about utility: CLEANING FLOORS a. Does is really sweep ALL the floor? Read a lot of reviews and looked at a variety of designs. Some reviews that I recall said "This thing finds a LOT of dirt. Where does it get it all?" After a year of emptying it (You DO need to empty its evening sweep into your trash, usually every day - VERY easy to do - again click out- click in) I totally agree! This thing finds a TON of dirt and dust that is NOT obvious to the naked eye. Frankly, that is its job and I need to make clear here that it does its job really really well. VERY SATISFIED b. To be utter clear however... I have a three story house. To define that though that is two stories with WOODEN and some tile Floors and a third floor that is mixed wood, carpet and concrete. PRO: I cheat. One robot for three floors of my house! Every day or two I pick it up from its charger, move it from floor to floor to let it clean a different floor whenever the mood strikes me. Works great! More, this thing cleans almost all of those floors flawlessly - especially the wood, tile and concrete bits. It sneaks into lots and lots of corners, under furniture and stuff and it never, ever runs off the edge of stairs. Completely satisfied. I admit I may be so satisfied because wood, tile and concrete are 92% of my floors and it is flawless on those types of floors. CON: This is a real review, not a feel good propaganda babble. If there is a con to this robot it is carpets. Specifically, it WILL work across modern carpet. That is carpet that is tight, laid level with the rest of the floor and has nothing to hang it up on. However, it struggles to go over edges, so if there is an edge to your carpet, a strip that it has to ride up over OR (Like me) you have a carpet or two that are Persian Style rugs with tassels at the end, just be advised that it WILL choke as it tries to cross these barriers. You can still do these surfaces, but you will have to stay nearby and bail it out when/if it hangs up... which feels time wasting. This should not make you hesitate to buy based on this review UNLESS you have a lot of these carpet barrier things about your house, in which case you will be annoyed by this robot. To be fair however, you may be annoyed by ANY robot under those conditions. Just think about it before you buy. ******** Utility NOTE! This is a final note on utility. The REAL Nemesis of any robot is WIRES/Cords. Once you own one, you will figure this out pretty quick. You will need to get your cords under control since the robots will find power cords on computers, lamps etcetera and choke up on them. 80% of the time when it does not return to its charger at after you program it to clean (Smart folks program that between 1AM and 3AM - unless you tell it to go manually for some reason) you will have to track it down to find it hung up on wires. Once again, to be fair, I think this is true of virtually all robots. They are not too bright about wires. The other 20% of hang-ups comes from some oddity in your furniture. I have particular chair in my study whose side supports are JUST a bit too short for the robot to go under, so it drive in there and wedges itself into the spot and cannot get free on its own. Just to you know, this is fair enough, robot makers cannot anticipate every single possible piece of odd furniture. Just figure it out through trial and error, but enjoy all the cleaning it does WITHOUT you paying the slightest attention. A small price to pay. *********Utility NOTE 2: The control - Comes with a remote. To be frank, I only use two or three features on the control. I tested them all at the beginning, but I've forgotten what the rest do. Most used? Manual use button. Because of how I use it on other floors, the automatic run feature is only good on one floor. Works flawlessly as far as I can see. I tote it to the second floor, put it down, hit the manual timed button and off it goes. I wander back up an hour two later, hit the off button and walk it back to its charger. Second most used? The recharge button - This tells it got back to recharge station manually. If you you do not want it to keep going you can interrupt its cycle and it will go back to its recharging. Usually use this when I am watching a show, it starts on its own and I find the noise distracts me from watching. Third most used feature? The manual steering controls. One review I read said this machine is really stupid. That is half true. It does fine most of the time, but if you want to steer it manually on occasion you can. I have a table I want to make sure it does under in a certain way, so I just point and click it to drive it into the bits when I want them to be cleaned. 3. Maintenance - Look. Old soldiers will tell you. Preventative maintenance will allow you to keep using your equipment day in and day out. This robot IS reliable IF you know you will need to maintain it! If you are lazy you will hate doing maintenance. I just make it part of day's routine and do not resent it. Thus I am very satisfied. My routine is to pick it up about 5 PM, sit and work on it for three to five minutes WHILE I watch TV. WHAT? You cry! Why so much work! The work is there because the robot does its job. All you are doing is making sure it keeps doing the job without hassle. Once again, whatever nonsense if advertised, I imagine ALL robots require this kind of looking after. PLAN on it. This one I suspect is no better or worse than any other. Do not go into it blind though. Here is what you need to know: a. You will need a little tool to do maintenance. If you buy the little kit with filters, brushes and a tool in it, know this. The tool is a hokey little plastic thing that CAN work... but takes a bit more time to use. Specifically it has a comb to clear tangle in your brushes. This works well. It has a little brush to brush dust off filters, off the inside of the dust/dirt collection box, etc. This works adequately. It ALSO has a little razor blade letter opener thing on one side intended to clear hair from rotors (Two types) This is a weak tool that works, but is time consuming and tedious to use. You are better off getting a little tool with steel blade or hook on it. Something you can use to really dig hair out of spots where it winds itself around a brush or rotor. Dig through your kitchen drawers, tool boxes or the $2.00 bins a the hardware store until you find something that works better for you. Maintenance: Enemy number one if long hairs. I have two women in the house. I am sure they do not mean to shed, but shed it they do somehow. This is what happens. As the little brushes turn they pick up hair and push some of it into the bin...BUT they also wind around and around the spinning brushes. Every other cleaning I find a wad of it around both brushes. There is also a rotor on the bottom the turns and does the sweeping up.. It ALSO picks up long hairs. Some will wind around the rotor proper and must be cut off or pulled off. This is the easy part. The hard part is that some will wind around at the ends where the bristles stop. This is where the recommended tool I mentioned will pay for itself as the hair tends to knot up tight in wind after wind. You will have to dig it out and cut it loose. You must also empty the bin at the same time. I also wash the bin out now and then along with the filter. Once a month or month and half the front wheel may also need to be tugged out (It pulls out and pushed back in easily) It ALSO gets hair down in there around its axle, though not nearly as fast as the rotors and brushes do. That is it. I will only close by saying I have NOT owned every robot in the world, but I imagine these periodic maintenance requirements will be very similar for ANY robot... NOT just this one, so if my maintenance picture here appear to be too gloomy, don't let it be. OVERALL: I am totally sold on having a slave machine keep my floors swept. Rather it than me! Call me lazy bones. A little maintenance now and then is well worth this machine. Go ahead and buy one. Jump in the water's fine.

11S Max Review First and foremost, when you're reading these reviews you will want pay attention to which vacuum they bought so that you know the reviews are about the one you're interested in. There are 3 or 4 different vacuums being reviewed on this same thread. Update 6\6\25: I noticed today why it tells you you should have six feet open space directly in front of the charging port: when the vacuum is returning home, she will go so many feet out away from the port so that she can turn around and line up to get on the charging nodes. In reality, I don't think she needs more than 4 ft... But there may be issues with her being able to turn around if there's anything blocking her. 6 ft is a lot of space, so you might be able to get away with 4 to 5, depending on your setup. Otherwise, you would have to use the remote to manually return her to the station, or pick her up and put her on the charger yourself. Not having the space is not a deal-breaker, it just means you will less of the "auto" features. Today I did let her run until her battery got low and she maneuvered herself back to the charger without any assistance. I also want to say she is doing a pretty job at cleaning. I'm used to having to sweep and then mop the floors... But after letting her run through the whole apartment for 2 days, when I'm up today it was such a nice smooth process. I didn't get a bunch of debris and hair and other things clogged in the mop (which we all know can cause problems like scratching on your floors). This little vacuum is a blessing! If I'm not mistaken I believe her paperwork said that she uses about 40 watts of energy... Like a light bulb... when charging. I would think that that means that her energy usage, while charging, is equivalent to leaving a lamp on. Original Review: I literally just got this vacuum this morning and only did a test run for about 20 minutes. A big reason why I didn't let it go all over the apartment is because I'm still in the process of moving and I have packaging everywhere on the floors, creating too many obstacles. With that being said, so far so good. I just let her run around in "Auto Mode" and she worked great. Yes, my robot vacuum is a "she." I named her Suki, as she "Suki a lot of dirt." Plus Suki is a name for "loved one," and I love her already!! I swore up and down I was never going to be one of those people who have one of these... and here we are. And I probably never would have if I had not stayed with my sister and her husband for several months when I first moved to a new State. They have one and I really noticed how much a difference it makes and keeping up with pet hair and everything else. What seemed like really haphazard navigation ended up being a lot more mapped out than it first appeared. While it look like she was just going in random directions with no uniform, I did start to notice that she was not going over the exact same path upon return. So, somehow, it's working to where I can tell the machine is covering everywhere. It definitely appears to be mapping while it's in use, but I know it does not store mapping. That's a big part of the need for Wi-Fi with other robot vacuums. I did notice that a couple people were complaining in the reviews about her constantly vacuuming just the edges by the wall... This is probably because they didn't realize that she was in that mode. Because you can literally make it so that she focuses only on the borders. There's quite a few nifty features that you can program the vacuum to do... And it even has a scheduling option so that you can schedule the vacuum to go off at whatever time you want (as well as a way to cancel the schedules if things change). Overall, pretty nifty. It does what I need it to do, and that's all that matters to me. I don't need a bunch of fancy features. My apartment is just under 800 square feet; therefore, I don't need it to do special mapping to try to remember where it left off after a charge. It's pretty much going to get the whole place on one charge. One MAJOR reason why I selected this, (outside of the lower cost) is because it does NOT require an app or Wi-Fi connection (in fact you absolutely cannot connect this particular vacuum to an app or Wi-Fi, so if that is what you're looking for this is not the vacuum for you). Sure, with an app you can do things like trigger her to start running before you even get home from work... But, quite honestly, that doesn't even matter to me. Because, if I learned anything from watching my sister and her husband's pricier, self emptying robot vacuum? It's that these things are constantly getting themselves into trouble and you need to be there to rescue them, anyway (which is a total drain on their battery if you aren't there to save them). So, there's no reason why I would need the robot vacuum to run while I'm not home. On a side note... I found it quite hilarious that the instructions say that you should not place her near the stairs or a cliff. And I was scratching my head wondering how many people with fortresses were buying these things. 😂😂😂 And speaking of running... Very quiet. I would have to say that my stand up floor fan is way louder than this thing. The AC unit is louder than this thing. I would assume that some of that has to do with the fact that the suction is not superior in this thing, as it's only at 2000 (really pricey robot vacuums are around 4,000). However, I have laminate floors (fake wood flooring in a linoleum-type flooring) and the throw rug in my living room is one of those very low profile new kind that are washable, which is comparable to a thick blanket. Speaking of the area rug... This thing had no problem going up and over and onto it regardless what angle she approached the rug. Sometimes she came onto the carpet straight on and other times she came up on to the carpet at an angle. And she didn't even blink an eye! As stated before, I only took her for a test run and she picked up so much "tuck" in that short timeframe. I was thrilled that she even got all the little itty bitty popcorn pieces from all the styrofoam my furniture and other items were delivered in. It's like no matter how careful you are taking things out of the boxes those little tiny popcorn pieces get everywhere and they are so impossible to sweep up. Keep in mind I had, just the night before, swept and mopped most of the area that she ran over today in her test run and there was still that much stuff in her canister The canister is very easy to remove. You don't have to flip her upside down or anything. You just push down on the little release button with your thumb and pop it out. That is also where you will find a filter that you can clean out. Read the manual that comes with it throughout. It's very helpful on how to keep her clean or else she won't work properly. I love the remote. She got stuck trying to go over packaging from my couches that was on the floor. When she didn't get the clue that she needed to back up and try something else, I just held down the down button for backwards and she totally backed up like a remote control car. I just pushed the right arrow button and she turned in that direction and I let it go and she took off. That was so awesome! When I felt that I had seen enough I decided to go ahead and use the remote to return her back to her charging station. She immediately responded (didn't seem to want to respond to the remote commands when she was in another room, though). Once you push the button to send her home to charge, she will start moving slower. I think this is just the devices way of being very accurate in homing in on her docking station so that she can properly align for a proper charge. And speaking of our proper charge when I first unpackaged her I had to put her on the charger to charge her fully as it is recommended in the instructions before use. And I noticed at some point the orange light wasn't flashing which is what tells you she's charging. So I just hit the auto button as if I was going to send her out to suck up my dirt... And after she got a couple feet away from the dock I just hit the return button on the remote so that she could get on the dock properly. Work like a charm... didn't have any issues with the charging stopping at that point. So I really can't comment on longevity for the battery or parts. But I will say it would be wise to purchase spare brushes and filters for down the road just so that you have them when you need them. Because these things do wear down with use. The more you use it the quicker it's going to wear down. Just a heads up. But these are not a "one-time purchase and forget about it," just like most bagless vacuums require maintenance and upkeep. There was some damage to the box that it came in.... Not sure if it matters or not. If anything changes I will try to remember to come back and update this review. I did purchase an extra 2-year warranty just to be on the safe side.

I have had this unit for over a year now, so this review reflects significant experience. First: I like it. I'd buy it again, though with a constantly changing market, my next one may be different. Second: Why four stars and not five? If I were basing my opinion strictly on value for price, it would be a five. If I were basing my review strictly on first-month performance, it would be a five. But, overall, over the course of a year, it just doesn't quite make a five-star rating. Third: The ONE MAJOR FLAW (could be included under "Why fours stars" above): This unit relies on 3 infrared drop sensors to avoid falling down stairs, or similar mishaps. You can see them when you turn it over. They are just like any other infrared close-proximity sensor in any other device (such as the pellet bin of a pellet stove) – they can tell whether or not there is SOMETHING, anything, within a certain distance, in this case, roughly the 1/4" between the sensor and the floor. If that distance is too large, then the device can reasonably infer that it is about to roll over a cliff, stop, and back up, which is exactly what it does. The problem comes when the machine has been in use for a while, and becomes covered with a slight layer of fine dust, and then later, when, through normal wear and tear, the red plastic lenses of the sensors develop very very fine scratches. Once either or both of these things happens, the sensors can no longer reliably tell how far away the floor is, and will stop the unit right in the middle of the floor in response to some tiny irregularity, or for no clear reason at all. If they're really getting dirty, the unit will stop, then slowly, cautiously back away, carefully looking in either direction as it backs up, but if they're really dirty, it will sense another drop and stop again, and slowly back itself into a nonexistent corner, which looks like nothing as much as a person hallucinating being attacked by demons and trying to escape. The sensors can be wiped with your finger, or with a sponge or towel, which will work for a while, but after a few months, they will develop fine scratches, and the machine will never perform properly. The solution to this was to use some extremely fine plastic polish to polish each sensor lens, which will ALMOST, but not quite, restore the machine's original function. I have an small hallway with an old wood floor with small gaps between some floorboards, and the machine can no longer operate there for more than a minute without becoming trapped in an imaginary net. If your floors are all very smooth and even, this may never be a problem for you, but if you live in a real house, it will happen sooner or later. The Good: • It still cleans the floor after more than a year of daily use. • After a year, the battery is still good. • It has survived several rounds of knocking a heavy wood cutting board that is propped against a wall on top of itself, with no apparent injury. • It has no camera, no microphone, and does not connect to my cell phone, WiFi, or the internet. The Bad: • This is a mindless unit. It does not map, it does not plan, it does not recognize messes or spills – it takes a completely random walk, invoking various subroutines when certain conditions are encountered, such as "follow the wall," which is also "go around the chair leg," "try persistently to get over the door threshold, and then give up if you can't," and "back away slowly and cautiously from the edge of the abyss," all of which are disturbingly engrossing to watch. • I wouldn't call it "quiet." It's not noisy, but if I wake up in the middle of the night, I can hear it several rooms away. • Its distress alert is earsplitting and persistent. It will issue ten loud sets of beeps if (when) it gets in trouble. This is very annoying at night, when you're trying to sleep, but it can be very helpful if you happen to be up when it gets lost somewhere you'd never think to look for it. • If it gets lost in the middle of the night, there is no way to find it when you come along in the morning. It has no "Find-My" feature. Once it crawled into a reusable supermarket bag under a table and the bag fell closed behind it, and I spent over an hour looking for it. For the most part, though, it tends to get stuck in the same places, so it's not hard to find. • Its filter is not well sealed against its mounting, so that it will suck some dust past the filter, which, over the course of months, will coat the entire inside and outside of the unit with fine dust, which can be sponged or vacuumed off, but which will immediately return. • This dust, by getting into everything, will get into the (almost-never-used) on-off switch, causing it to stop turning the unit on. This can be remedied by popping the switch out and spraying it with contact cleaner. • The dust tray is hinged. The hinges will break off, unless the hinge pins fall out and into the garbage first. There is NO NEED to replace the dust tray when this happens – it works just fine with the hinges broken and is easier to tap the dirt out of. • It can be disassembled and repaired, but, because many of the screws tend to strip out the threads of the plastic they're attached to, it can probably only be disassembled once. My experiences with this unit: • It worked well out of the box. Setup was minimal and simple. Instructions were pointless and confusing. • Its strategy is that if you randomly roll around a room long enough, you will go over every point on the floor at least once. This strategy works. • It cannot clean the final ~1" of corners, because it and its spinning corner brush are round. This is generally not a big deal. • It will clean places you were never able to reach with a normal vacuum – way under very low furniture, for example. • Initially, it very seldom got stuck anywhere, but over time, it seems to have become less capable of mounting several fairly high door thresholds, so it bounces along them, and often half-climbs them and gets stuck. • If the dog pukes and it runs right through it... well... 'nuff said. • You can frequently vacuum the vacuum with a soft brush attachment, but if you don't its performance seems the same. • The one mechanical failure I had in a year was the spinner brush motor stripped its gears. It still spun for a while, but made a terrible noise. I bought a replacement motor unit on... Amazon... for about $20 and followed video instructions to replace it. It was a bit involved, but I was able to do it in about an hour, and it's worked fine since then. Good luck!

This (really long) review is for the Eufy 11S Max robot vacuum (Robovac). Please note “Max” vs regular 11S. They may look the same; but the Max uses a different filter and has the higher 2000pa suction. Otherwise the functions and options (other than suction choices) are the same. I've used the 11S Max for the last month on my low pile carpet (about 80% of the roaming area) with the rest being tile or linoleum flooring. It has been quite fascinating to watch so I've actually put about 85-90 charge cycles on the unit over the last month (yes, three times a day on most days and it's still finding more dirt/dust than I would expect). Right up front, I'd definitely buy another when it comes time to replace this one. After comparing how I vacuum my flooring, especially to pick up my biggest carpet enemy; short stray bits of dried grass stems, the “random” wandering of this vacuum model made more sense to me than the other fancier choices. Most vacs do a good job with dust, dirt, sand, cheerios, etc. but these stem pieces are only picked up by a vacuum when it comes at the stem with the brush roller pretty much parallel to the stem. That means random directions will more likely get these pesky problems than an organized back & forth cleaning approach. Granted it may take a few cleaning cycles or several passes over the same area during one cycle; but since the Robovac has completed its first 5-6 cycles I rarely find them anymore or if I do spot one it's not for very long. Robovac is a big time saver as well as an energy saver for me. I would use my canister vacuum about an hour each week for routine cleaning and once a month for 2+ hours to do a more thorough cleaning. A watt-hour meter indicated that my canister vacuum used 5-6 kw-hr of electricity each month. Robovac uses about 12 watts continuously for about 4 hours when charging (surprisingly less than the 5-6 hrs listed in the manual; but it is brand new). Once the battery is charged, the power consumption drops to about ½ watt. When Robovac is away cleaning, the charging base uses just ¼ watt for the homing beacon. So if used just once a day; Robovac would only use about 60 watts per day. That means once-a-day cleaning would only use 1.8 Kw-hr energy per month. By letting Robovac take over the regular weekly cleaning with once a day operation (or less), I'm able to cut my electric bill by an easy 3-4 kw-hr/month. With that said, there are a few things that I think need improved: First, there should be an interlock on the dust bin – Robovac will merrily go off about it's scheduled cleaning cycle without the bin installed! So if removed for emptying; don't forget to re-install the bin before the next scheduled operation. Plus, I noticed on a couple occasions, that I wasn't paying attention and I left one corner was about 1/8” out from fully inserted. Not sure if that will cause suction leaks; but you need to make sure the bin is completely inserted. Second, you can't select “max” (or any power level) when using the remote to manually clean an area. It appears to only operate on “standard” suction with manual operation (i.e., when Robovac is not running a regular cleaning mode and you chose to override it's direction). In addition, if you select the remotes' edge or spot cleaning modes it will automatically go to “max” power for the duration of that mode and you can't choose IQBoost or standard power level on those selections. Third, I don't know why the 20 minutes for edge cleaning or 30 minutes for quick cleaning was selected. Robovac can make it about 60-70% around my home in the 20 minutes of edge cleaning. If edge cleaning mode was permitted to run until it made a trip all way around and back to the charging station where it could dock to finish that mode would work better. An alternate solution would be if I could set the cycle time for edge cleaning and quick cleaning modes. Plus I'd like having an option for it to simply stop when the time is up rather than automatically returning to the base. When I want just one room cleaned; I'll set Robovac to auto or quick mode in that room, then close the door or put down a barrier, and return later to stop it manually and take it back to the charging base. If I don't return in a timely manner Robovac will be trying to locate the charging base and running the battery down. Fourth, Robovac cleans edges using only its right side pretty much all of the time. It would be helpful to have it randomly choose using either the right or left side whenever edge cleaning. I watched it edge clean a carpet/wall area three times going only in a counterclockwise direction (right side) and it still didn't pick up all the dust bunnies. I used manual control with it hugging the wall on its left side and it picked them up with no problem. Also, be aware that manual operation, when Robovac is not already working in a selected cleaning mode (overriding current movement), only works while the remote buttons are pressed. Robovac stops all functions shortly after a button is released when used manually. Fifth, I really don't need to run Robovac on a daily schedule – there should be a weekly scheduling capability even for the least expensive robot vacuums. It shouldn't be that difficult or expensive to update this model to correct this issue. Even if it's the same set cleaning time, every day for the selected days; just give me the ability to schedule cleaning cycles one to seven times a week. Sixth, when the battery runs low, Robovac can take forever, if it makes it back at all, to the charging base. I will routinely go looking for it if I haven't seen it return within 10-15 minutes after the approximate cleaning time has passed. The age-old solution for solving a maze (your home from Robovacs' perspective) is to constantly follow along obstacles using just one side (Robovac does recognize when it's circling something like a coffee table and adjusts accordingly after a 360 degree rotation). This method is how Robovac tries getting closer to the charging station when it's more than about 15ft away and not in line-of-sight (the charging base emits an infrared signal for homing action – make sure you keep Robovacs' bumper and the base clean). Sometimes Robovac occasionally gets diverted or the software tells it to try something different) and it will go off in another (often wrong) direction (extremely frustrating!). I highly recommend observing Robovac perform it's return operation from various areas in your home. I ended up placing a 2x4 along the end legs of my sofa as Robovac was consistently going along the side skirt, under the skirt at front of the sofa, then around the front leg exiting the side of the skirt, and then heading straight across the room. It would then go thru three other rooms and come back to the sofa again. The 2x4 forced Robovac to continue edging under the sofa, along the back wall, and out the other end which has an end table that mimics the 2x4 at the opposite end. Before using the 2x4, Robovac took well over an hour to get back to the charging base (it eventually changes up it's routine, usually after three tries) and required 5 hrs to recharge. With the 2x4, Robovac has been able to get back from the far end of my house to the charging base in under 20 minutes very consistently. While the ability to improve Robovacs' return mode is really limited to what you can do, the key point I'm making here is that the battery will always give you more charge cycles (longer life) before needing replacement if you can get Robovac back to the charging base as soon possible. Seventh, pay attention to the thin rubber wiping strip on the brush guard. After 60+ cycles I noticed the ends of the thin rubber strip (about 1/16” of it's height) were tearing away. I believe this was most likely due to moving back and forth over edging from tile/linoleum to carpet or maybe due to the floor mounted furnace registers in my home. I simply trimmed the torn bits off to keep them from getting caught by the brush. After about 100 cycles I noted the rest of the 1/16” strip was now gone. This impacts the tile/linoleum cleaning far more than carpet; but it is something to watch for. I highly recommend checking the rubber strip during brush cleaning and purchasing a brush guard replacement as part of a maintenance set. Hopefully the manufacturer will improve the thickness or type of material used to prevent or at least reduce this problem occurring in the future. Next, a few helpful hints I've learned or didn't find in the owner's manual: The “bowl” shape on top of the charging base with the white LED is just right to hold the remote control, button-side up. However, I prefer to turn remote controls' button-side down to keep them cleaner so it's up to you if you use it or not. I've had a few occasions when Robovac actually bumped into the charging base so it was no longer sitting square against the wall. This will impact it's ability to find the base when the battery is low. I took a used rectangular-shaped one quart motor oil bottle from my recycling bin, cleaned it thoroughly, and filled it with sand. It's now a 3-4lb weight sitting on top of the charging base. I haven't had the base re-positioned since adding the weight. Normally Robovac does a good job avoiding the charging base; but not always. Robovac “parks” about 1/2” away from the charging base tower. If you are careful, you can swipe a cloth over the bumper sensors to clean off any surface dust that has collected (always seems to be some); however, be careful as Robovac might activate while you are doing this. You might also get a solid red indicator without any beeps. This error isn't described in the manual; but I've found if I just lift Robovac off the charging base for few seconds and then replace it, it will change back to the charging orange color. (I suspect the solid red indicates a sensor error) It's also quite easy to remove/replace the dust bin during charging. Unfortunately you will need to flip Robovac on it's back to remove/clean the side and roller brushes as well as the bottom IR sensors and charging contacts, so remember to turn Robovac off with the topside button before doing this or get used to it trying to start up while you are cleaning it. Also make sure the blue/orange indicator light is on when you reposition it on the base. Sometimes Robovac will remain off rather than return to charging mode. After two or three cleaning cycles I'll do a regular check on the all the brushes and swap left and right side brushes when they are re-installed; seems to straighten and make them work a little better, maybe last longer too. Oddly the remote control spot clean button symbol and the manual indicate a clockwise spiral for the cleaning operation; but when I've selected it, Robovac has always used a counterclockwise rotation. If the side brushes happen to “hang up” on something, Robovac will stop spinning them while it maneuvers around the obstacle and then restart the brushes when it thinks it is clear. Don't assume there's a problem when you see this unless Robovac beeps and the indicator turns red. The flat handle end of a spoon or fork works great for prying the filter free from the bin for cleaning. Every time I have tried using my fingers; it pops out tossing dust/lint everywhere. The IQBoost mode doesn't seem to change going from hard flooring to low pile carpet or vice versa in my home. I think this is because the low pile carpet just doesn't cause enough “drag” for it to recognize that it could adjust the suction level. (I'm still not clear as to whether there's just two suction levels or if Robovac can vary linearly between the two) While the manual indicates a 40 min run time in “max” mode with medium nap carpet, I'm obtaining about 60 minutes with my low nap carpet. I do find the “max” mode clearly picks up more dust. I ran Robovac 20+ times on IQ mode before switching to “max” for its scheduled operation. The filter has clearly shown a thicker layer of accumulation on the filter. When “max” mode is set as default you will occasionally hear the vacuum whining noise change briefly. Best I can figure is it's a software glitch where the IQBoost code tries to adjust the suction level; but then resets it to max. I normally hear this shortly after Robovac goes from one flooring type to another. It also occurs shortly after it starts it's routine. Robovac does not communicate back to the remote. So if for instance, you press edge cleaning and Robovac doesn't get the message, the remote will show it should be performing edge cleaning even though it's not. Similar situation when Robovac is recharging or is returning to recharge; the remote will still show it's in the selected cleaning mode rather than the “charging” icon. You simply have to pay attention that Robovac has recognized your command by a “beep”. I found using the basketball nozzle with my Ryobi P737 inflator does an excellent job cleaning the filter. It takes only a couple minutes to clean both the filter and the bin (outdoors of course!). The original filter has been cleaned well over 100 times now and other than being a little dingy it's still working great. This should help stretch the recommended replacement interval to more than 2 months compared to the recommended “tapping it” to clean. Do not use the “canned” compressed air as I frequently find it wets surfaces during extended spraying and the Robovac filter is a paper element. If you have a sofa, chair, etc, with stiff or heavy cloth skirting down to the floor; I suggest safety pinning up at least a foot or two of the skirting on an open side. When or if Robovac switches to using the proximity mode for cleaning AFTER it gets under the furniture, the skirt will appear like a wall and it will keep running around underneath the furniture until it switches to a collision mode where the weight of the skirt generally will not trip the bumper sensors and stop it from escaping. I'm glad I've used Robovac during the daytime so I could track it down and figure out what trouble it got into during its normal operation or when I expected it to be back at the charging base. The alarm beep sounds can easily be missed when it's far away from you. Plus, when it powers down after getting stuck can make it lot more challenging to find! It's a lot easier to locate when the vacuum sound is still going or even if it's just the quieter wheel motors running it around looking for the charging base. To wrap up my review. I've found Robovac to be a well built, nicely designed, and quite durable robot vacuum. The $160 price I paid is quite reasonable with excellent cleaning ability (given it has about 1/10 the suction of a typical canister vac). It has good battery run times (my mixed flooring on IQ mode lets Robovac run about 80-85 minutes before recharging), and it is a wonderful time and energy saver. If you've been thinking about a robot vacuum without all the extras (or just don't like vacuuming), the Eufy 11S Max is a great choice.

"Simplicity is the ultimate sophistication"-Leonardo Devinci [Just like EUFY] It is now the nearly the end of 2020 and still going STRONG, SMART. SLEEK-- no need to replace battery, yet especially with the rare on/off switch on the bottom side. Also, with the tempered glass top still no scratches (all pictures updated). Looks and performs as amazing as the day it arrived for a solid 100 minutes! My favorite robotic vacuum of all time Highly recommended! ★★★★ Quality ★★★★ Price ★★★★ Shipping ★★★★ Description ★★★★ Smart Features ★★★★ Durability/Best in the industry ★★★★ Home Docking/Recharging ★★★★ Cleaning&Sensors EXCELLENT ★★★★ Longevity (a forever robotic vacuum) ★★★★ Gets under everything! Dust Bunny 🐰 Free Hone!. Original Review To set your expectation consider yourself LUCKY to have found this Eufy even though it is not APP operated, YET still out preforms all competition and has built on remote holder for scheduling with excellent client support to help replace also just press button for maximum cleaning on unit. Eufy is made by Anker ( approved) an incredible technology company that offer such inexpensive and extraordinary innovative power that you can find their products on the  Apple site and all of my experiences have been nothing, but amazing with Anker so when I realized Eufy was an Anker product I knew I scored big time. IF I had only known what I do now “SIMPLER and SLIMMER is ALWAYS BETTER” after 7 ULTRA SMART and FRUSTRATING Robotic Vacuums which only makes me appreciate this Eufy even more. Firstly... Could've saved a fortune! Something you have to learn the hard way. Save this link if you think otherwise because you WILL BE BACK. THE ‘Eufy’ EXPERIENCE: • Add to your Cart and Stalk I randomly found for $149 on lightening deal ⚡️and would’ve bought 2 white (hard to find) if I’d known it’d be this perfect (will update— always do if there any surprises and adjust Star Rating/Review). • Arrives quickly and I was certain it’d be another return and so far it has been the best out of 7 Robotic Vacuums in 3 Years thus far. • The 1st charge (extremely important to NOT turn-on without fully charging) is unbelievably FAST for a Robotic Vacuum. I actually received it before heading to the airport and could not believe I was able to test it fully changed before I was out the door in a rush! • I really appreciate that this is a FOREVER vacuum, unlike competitors Eufy by Anker this is the perfect option you can keep forever because they offer a replacement battery for $22 PRIME and an ON/OFF switch underneath I have never seen ever (to conserve battery life). I much rather pay $22 PRIME than be FORCED to buy a whole new vacuum which is extremely common in the robotic vacuum industry. Electronic products are made this way and die around the end of the warranty IF lucky and not 3 months (I've been through this 3 times) and force you to buy an entire new unit when you just pop a new battery in. Have fun with that if you skip. You will be back! • The batter offer replacement is way better than spending another $500 on avg. and it is designed in a way you just pop to in. So crazy and wasteful the robotic vacuum industry can is. Super impressed. • Eufy runs for 100 minutes of cleaning time when the Ultra Smart Vac’s need a full 12-24 hour charge before a test/cleaning and an industry standard of 30-40 minutes of cleaning time. • Eufy is THE ONLY ROBOTIC VACUUM TO ALWAYS FIND ITS WAY HOME TO DOCK AND RECHARGE— EVERY SINGLE TIME! Mind blown! I've only had one of many vacuums actually find it's way back and dock a total of 3 times. They ALWAYS claim it goes to it's Home/Charging Dock, yet never do! I simply cannot believe it! • It has a clever On/Off underneath which will help conserve your vacuums longevity if you do so choose. Something I have never seen and would’ve not appreciated until now after all the expensive duds. • In the video it sounds loud, yet not at all as loud as my other’s. It sounds like a blade less Dyson Fan if you are familiar. i.e Smooth Air Blowing • The accessories like extra filter, sweepers (the highest quality I have ever seen as they tend to arrive bent), comb with cutting tool (should be used everyday you run it and is extremely common with all Vacuums as of yet), etc. • Easy manuals no weird or bad grammar to scare you off that is all too common now. • The sensor is as common as all it will bump things just like a very expensive Vac and is very alert to People and Animals. (Updated has better sensory than any of my other 7 adventures, yeah still bumps but now notice not nearly as much as all other brands). • I am so used to Vacuums never ever finding their way “Home”, so why set a cleaning schedule. Pointless. Eufy you can confidently. • The simplest way to ensure it always finds its way home is to make sure all cables/wires are not on the floor which is common knowledge to Robotic Vacuum owners. No, it won’t destroy cables it will simply shut off and need to be manually docked otherwise your set for a cleaning schedule. • Far too many Smart Vacuums are just too thick to clean under platform beds and furniture and if they cannot fit under I am just not interested. Why have one if it’s not going to do “Spring Cleaning” everyday and keep your home fresh, dust mite and dust bunny 🐰 free? It’s by far one of the most desired features speaking for myself. • My most preferred Vacuum’s have been By Eco Vac’s DeeBot Pro’s (owned 3) most are slim enough to get under most everything and they mop (I don’t like my area rugs mopped so, only tired that once) they have several issues, but have been the Top for me since Eufy which I highly prefer to my Eco Vac M83 PRO that I will be giving away if Eufy keeps up being superior. • Area Rugs... Eufy is highly intelligent when it comes to area rugs from thick to thin (also carpet). My once preferred Vac was okay, but would always have a the toughest time on thin rugs by flipping them and dragging them, also trying to climb her high sheep pelts and getting stuck. Eufy is super smart with its sensor to stay away from fluffy pelts (those are dry clean and sheep pelt brush) AND thin and high pile rugs Eufy has ZERO ISSUE when cleaning. Just AMAZING. • Also, excellent for finding a diamond earring you dropped etc., yes, I absolutely use it to FIND Small Impossible things without damaging! • I feel this covers all the major bases and is an excellent Vacuum I have waited several years for. Simple, slim, intelligent, and still cannot believe it runs over an hour and always always finds its way home to reboot and APPS have no become way overrated and a pain in the butt! Eufy Compared To Ultra Smart $$$$ Vacs: • I have owned 7 Smart Robotic Vacuums; the highest priced being the “Ultra Smart” Neato (returned after nearly a month of nonsense) with Home Mapping Technology at $1K. Sorry, the bigger, thicker, wider, and SMARTER it claims to be in my experience the more dumb it is. It becomes more of a chore meaning you have to reset the map every single time you move something and they are so thick they can cannot get all the dust and debris under furniture like Eufy does effortlessly. • Eufy cleans for 100 mins & always and I mean always finds its way home (something I was always promised, but they never returned even when commanded) so you can truly set a cleaning schedule! • While most all Smart Vac’s claim to dock and charge on their yet ALWAYS alert you over and over that they are stuck or have to be searched for with app, yet, Eufy is always obedient and doesn’t even need that function!I have only seen Eco Vacs find its way home 2x in 3 years now after 3 models (of that brand), Neato never, Dyson Eye never ever again! • It is proven that Vacuums that run in straight carpet lines are less efficient at cleaning. Hard to believe, but random has proven to out clean the $1,000 USD Plus Vacs. • If I had known it’d always do a no nonsense cleaning without me having to follow it I would’ve withdrew doubt and ordered 2 at $143. • Eufy keeps it Simple, Sleek, Very Slim (gets under virtually EVERYTHING and ANYTHING you can imagine compared to Neato and other very high priced Robo Vacuums that cannot even get under a platform bed and other low profile furniture meaning dust will continue to pile up). One Con (maybe I missed it) no phone app to control while away. If so DO NOT LOSE THE REMOTE. I may be wrong. I am writing a review after a 3 day trip that I set a cleaning schedule to VERY IMPRESSIVELY FIND EUFY Nearly FULL BIN Scheduled to clean once a day while away FOR 3 DAYS (house is always clean) and sitting at its docking station. An Easy 5-Stars Buy Eufy and forget the hype over these Ultra “Dumb” expensive Vacs that do Nothing, but turn you into a Vacuum Babysitter! I would seriously have to follow a $400-1k vacuum around. Yes, this is a huge deal to me after never having this experience with purchasing so many Ultra Smart crazy expensive vacuums. If you are sick of babysitting your smart cleaning devices this simple, slim, chic vacuum is the Answer! Update August 15th 2019 WOW this would be 10 stars if the option was available! The sensory oddly seems to have improved. Has now problem cleaning BIG messes. Eufy has a crazy “hop” and still intelligent enough to avoid my sheep rugs that insanely fluffy and vacuuming is forbidden for care. Perfect. It does not flip, move around very thin rugs, or get stuck under them a common issue with super expensive smart Robo Vacuums! It continues to impress! I pick this Eufy over all of my ultra Smart experiences. I could careless about apps! The remote is great and if lost it automatically turns on with a press to it’s Mac suction and gets the job done better than iRobot, Neato, Dyson Eye, several ECOVACS Pro’s, etc.. Save your money, time, and hassle of the Smart (dumb) options. I no longer have to follow an over-priced Robo around, get alerts it’s stuck, haven’t had to use a smart beeping tracker to track it down. It buy far has the best built-in features to schedule and forget. The only TRUE robotic vacuum you do not have to even think about turn on or schedule and forget about. The only thing it’s missing is to dump itself out! Mind blown! Finally, a Robo Vac that does exactly what you’d expect. Forget the hype or when your over all the overpriced Vac’s you WILL return or just die on you save this! Only then will you truly see the beauty of simple effective cleaning that you don’t have to babysit! Why buy a new robotic vacuum when Anker's Eufy has an easy (not hidden) inexpensive battery? Otherwise with other brands you FORCED to buy a whole new unit! eufy RoboVac Replacement Battery Pack, Compatible with RoboVac 11S, 11S MAX, 15T, 30, 30C MAX, 15C, 15C MAX, 12, 35C Accessory Save or 1-click buy for the BEST you will find!

I have spent weeks researching robotic vacuums. After comparing and contrasting different models from big-name brands like iRobot, iLife, Eufy, etc, I figured this would be a good budget vacuum. I bought this a few weeks ago and have been using it. Here are my thoughts. Build/Physique: This is a very sturdy unit. It has the classic round shape other robotic vacuums have. It weighs a few pounds but isn't too heavy. It's big enough where it can suck up a good amount of dirt, but not so big where it can't get underneath things like tables, but chairs can be a bit of a different story. Setup: Setup is easy. I just followed the instructions and put everything together as described/shown. Controls: What’s nice about this vacuum is that you can control it with a physical remote (that comes with it) or the Eufy app on your smartphone. The app has slightly more functionality than the remote, but it’s trivial depending on your needs (see below). I don't personally need the app, but I can see why it would be convenient. Some folks may want to run the vacuum while they're away from their house. Maintenance: Remember, the only robotic part about the vacuum is its ability to scour your house and suck up dirt and muck. It is not a self-maintaining machine. That being said, emptying the dustbin is simple -- you just press a button, release the bin, unfold it, and dump it out. The filter is also easy to pop in and out. If I'm not mistaken, there are one or two filters that are washable, along with some disposable ones. Cleaning the roller brush and the side brushes is also very easy, and there are extra side brushes that come with the unit. If you need more, you can order individual parts or a kit that (I believe) 8 side brushes, one or two roller brushes, and some filters (sorry, I don't know the quantities). Performance: This is where the fun begins. If you're not familiar with how robotic vacuums operate, here's a quick breakdown -- models like this one and many of the lower-end machines just blindly roam around and pick up whatever they find. More expensive units have navigational systems that allow them to map your house and create a floor plan so it knows where it is, where it's been, and where it hasn't been. Both WILL vacuum well, but the higher-end vacuums perform more efficiently. This vacuum roams around blindly, and it can be very frustrating to watch it move sporadically around your house. I also own an iRobot Roomba 980 which does have the mapping capabilities, so it covers the same amount of space in far less time. All this being said, however, it does have great suction and picks up things very well, including dog hair. I have a medium-sized yellow lab that sheds profusely, and it manages to suck up the hair very well off of hardwood floors. It also manages low-pile carpets well, too. Don't get this vacuum (or any robotic vacuum for that matter) if you're planning on vacuuming deep carpets, especially if you're trying to get dog hair out. Make sure that you pick up loose wires or any obstructions on the floor. These vacuums need as little interference from objects as much as possible. If you do forget to pick up a wire off of the floor, the vacuum has a feature where if it accidentally sucks it up, it will recognize it is a wire and drop it after a few seconds and move on. My Roomba 980 doesn't do that (to my knowledge). In general, it does well with not getting itself stuck. I have a pretty large divider that separates my kitchen floor from my dining room floor (about 3/4 of an inch), and it manages to get over the hump easily. Another nifty feature the vacuum has is cliff detection, so if it approaches stairs, it will not fall down them and get damaged; however, there's a drawback to this. If the vacuum encounters carpeting that is dark, the it might think it's seeing black and not continue to clean that area, so it'll move away. Stray away from dark-colored carpets if you can. It may bump into things from time to time, but there won't be any scratches on the unit. It has a bumper on it that will receive the impact of any collisions it has with objects it finds. There are three suction power settings, escalating in power from 1 to 3. You can adjust with the remote and I would assume the app. It even beeps the number correlating to the suction power when you press the button, so 1 beep for suction power 1 (or the lowest setting), 2 beeps for suction power 2 (or the medium setting), etc. If something goes wrong, it will beep in patterns, and you can check what error message is being denoted. I also like this feature, and the beeps are pretty loud, too. The unit is fairly quiet. You can clearly hear when it's on, but it makes a fraction of the noise a regular vacuum makes. This would be good for people who work from home but want to run the vacuum. Other vacuums (including Eufy's 30C) has a feature known as boundary strips or virtual walls. These are devices, or magnetic strips in Eufy's case, that send out a signal that prevent the vacuum from crossing a certain point/line. If you didn't want the vacuum to enter a certain area of your living room, you'd just have to put down one of the strips/set one of the walls at that area to prevent it from entering that area. The 15C Max does NOT have this feature, which I personally enjoy and would prefer to have, but, like having a regular vacuum, you're going to have be tidier if you want the vacuum to run without any problems/hiccups. You can also schedule the vacuum to run at certain times, which can only be done through the app. This feature is meant for folks I mentioned earlier that want to run the vacuum while they're not home. The app also shows you the current state of the vacuum: whether it's in standby mode (which just means it's docked and turned on), cleaning, and offline. Battery Life: At a full charge, I managed to get about an hour and a half (90 minutes) worth of a cleaning cycle out of it at the highest suction power. Eufy claims you can get up to 100 minutes at a full charge, so I'd say this checks out. The extremely convenient feature of this vacuum is that it is self-docking, which means if you press the power/home button on the remote or app (or if the unit's battery is low), it will stop cleaning and return to the charging base all on its own. It does behave strangely if the base isn't in a clear location/up against a strong-walled surface. So, make sure you don't have anything blocking the path for the vacuum to get to the base, and ensure that the base is firmly against a wall. This is easily one of my favorite things about this unit. The Bottom line: For $280, this vacuum rocks. You won't find a more powerful machine. It has some great features like painless setup, automatic self-docking charging, auditory suction power and error codes, cliff detection, compact size, a great battery life, powerful suction, flexible control devices (remote/app), easy maintenance, scheduling/automation, and cheap replacement components for order. There are certainly some drawbacks like darker carpets interfering with cliff detection, randomized roaming that doesn't make sense, and no boundary strips, but again, consider an iRobot Roomba 980 whose price is currently $900 as of 07/21/2019. It does have mapping and virtual boundaries, but you need to consider the significant price hike comparing these two particular models. Is it worth three times what this unit costs to pay for a machine that does have those features? This is in no way an insult to iRobot, but not everybody can just drop nearly a grand on most things, especially a vacuum. Take it from me who has a machine capable of efficient navigation. I'm glad I got both and was able to test them out. Watching the 15C Max after using the Roomba 980 is painful. But again, three times the price. The Eufy is still very powerful and picks up dirt/hair great. The Eufy BoostIQ RoboVac 15C Max performs very well and has plenty of awesome features with just a few drawbacks, and I truly believe you won't find a better robotic vacuum for under $300.

Great vacuum performance, but mop/scraper error made me return it I used this robot vacuum for about two weeks. As a vacuum, it worked very well. The suction was strong, the navigation was accurate, and it did a good job recognizing carpet versus hard floors. I had no real complaints about the cleaning performance, and it never got stuck during use. I also have two cats, and it picked up cat hair very well. Of course, with pets you do need to clean it regularly because the brush and dust area can fill up with hair pretty quickly, but that is expected. The problem started only after I began using the mopping function. After a few mop cycles, the robot kept showing an error saying that the scraper was blocked and needed to be cleaned. I checked it several times, and the scraper area was completely clean. It looked like the problem was inside the robot itself, not an actual blockage. I contacted customer support just to see what they would say, but the support was not helpful. They only replied with standard troubleshooting steps that were already shown in the app and that I had already done before contacting them. So the support did not really add any value. I returned the unit within the 30-day return window. Overall, if you only plan to use it as a vacuum, I can definitely recommend it. It cleans well, has good suction, good navigation, and handles pet hair well. But if the mopping feature is important to you, my experience was disappointing because the scraper error made that function unreliable. And if you only use it as a vacuum, then the whole point of buying a vacuum-and-mop model is kind of lost.

I always thought these robot vacs were kind of a silly gimmick, too expensive for not enough gain. After a couple friends raved about their robovac's, I made excuses like "My home layout is too complex!" and "I'll need three of them to vacuum my home!" But, the robot wars have made them cheaper and better, so I decided to finally give in on a good deal with this new model from a well trusted brand. I wasn't willing to pay for units with home mapping features and no-go zones, but with this unit, I don't feel I even need it. Turns out, I am absolutely thrilled with the performance and price point of these Eufy's. There is little doubt this unit is just slightly smarter than a bag of hammers. Thank goodness I can make it do it's work at 4AM when I don't care how many times it goes over the same spot or misses something that is just "right over there you stupid bleeping robot!" But, day after day, this hunk of electronic sensors strapped to a vacuum comes home with a bin full of stuff. I'm at the point where I don't even know where it gets the stuff and I'm seriously questioning my ability to clean my house. And also somewhat ashamed of the filth that I've lived with and didn't even know about. It goes places it probably shouldn't and if you have any degree of OCD, it will hurt your brain to watch it. It goes under furniture and shelving where it barely manages to escape, plays ping pong with table/chair legs for a bit and it has an inexplicable infatuation with the clear storage totes under my guest bed. It'll really like one area/room for awhile, but then will go elsewhere, only to be back 2 minutes later...and you're like, "Well, that was the *least* efficient way to do that. Whatever, a goldfish is smarter than you." Whenever I'm in the kitchen doing something, it has the whole lower floor it could be cleaning, but it will insist several times on cleaning the spot right under my feet. It loves to chase my cats and in turn, my cats will engage it in a battle of home domination, swatting it and trying to eat the spinny brushes while it charges. One cat will lay on the lower step and lazily swat at it as it goes by. Just when you think there might be the slightest sense of intelligence and you're having this "It's alive!" moment, it reminds you how dumb it is by gently ramming itself into a piece of furniture. I don't know how it does it, but despite looking like it couldn't find it's way out of a paper bag, it somehow manages to find home base for charging most of the time. But, it gets around, even in an ever changing layout. It deals with my wood floors, several area rugs and a section of medium pile carpet without much incident. It hasn't once tried to go over a stair in my home. It gets probably a good 70%+ of a complex, 1,000 square foot U-shaped layout of my main floor, with plenty of furniture making navigation much worse. But, it does that 70%+ every day and I don't even have to think about it. Based on the sheer amount of cat hair and dust this thing picks up daily, I'd say the suction and pickup mechanisms are pretty good. I can't tell you if they're better than older Eufy or other branded units, but the spec's say so. I was worried about how much of my lifestyle I'd have to change to adapt to this thing. Turns out, very little. I can still leave stuff around if I want and it won't try to eat everything in its path. It does occasionally try to commit robot death on various cat toys the kitties leave about, but that's maybe one 1 out of 10 times it needs saving. I have a rug in my kitchen that it loves to push into a pile, but that's only a minor annoyance and doesn't cause it harm. I have to be careful not to leaving charging cords and such about. Once every couple weeks it won't find it's way all the way home, but it's usually pretty darn close to the charging station by the time it dies. I thought it might become inconvenient to "save" the unit from it's self-inflicted stupidity, but the value it provides exceeds the inconvenience. I can see why people like these things. And there's a good chance I may buy the three I need, maybe this one or maybe others. But, for now I'm pretty happy with this one. It's a 5 out of 5 cat toy and a pretty useful home appliance that will save you time and improve your home's upkeep. I'll update this review with any significant changing opinions, but for now this "dumb, smart thing" gets 5 stars. Update: About 4 months after running this thing daily, one of the side brush motors started to malfunction. Normally, a product malfunctioning that soon would irk me to reducing my review stars immediately, but I sucked it up and contacted support. I requested, specifically, to do a self repair of the brush motor right out of the gate. They didn't request for me to send it in for repair, demand an expensive cross shipped replacement or question my self-assessment to repair equipment that I owned. They just told me they have the part in stock, requested I send them a video of the problem, asked for the address and put the brush motor in the mail. They then confirmed that if this didn't make it work right, they would still support me until it did. They worked with me exactly how I wanted them to, stood behind their product 100% and for that, not even a single star will be reduced from my original review. Update 2: I knocked two stars from my review. Not because of the unit, which is still great, but because of the replacement air filters. They are $11 for TWO of them! That's nearly 3 times the price of the previous filters, or about a $65 annual operating cost when changing them out once a month. IMO, that's simply too expensive for a vacuum and even my high end upright isn't nearly that expensive to operate using *HEPA grade* vacuum bags. Not just that, they are incredibly terrible for the environment by requiring you to buy the substantial plastic filter housing every time. Had I known this at the time of my purchase, I would have selected a different unit - probably the initial version of the 11S. Final Update: I've decided to just let this thing die a slow and painful death. Both of my side brush motors went out, as did the one that I replaced. It's still marginally effective without them, but definitely not as good as having them. Eufy's support reached out to me several times, which was great, but I have better things to do than rip this thing apart every few months to fix plastic parts that will fail again in 3 months. I expect more from something I'm paying $200+ for, definitely not three of the same exact failures within a year. Oh, and there's much cheaper 3rd party filters available for this guy now.

Muy buena aspiradora para el precio. Limpia excelente y no hace mucho ruido. Me preocupaba lo del ruido porque tengo mascotas, pero después de una semana se acostumbraron y dejaron de tenerle miedo. Recoge muchísimo pelo y polvo, así que el piso se ve más limpio que solo barriendo. Pedazos grandes se atoran, así que hay que recogerlos aparte. También a veces hay que guiarla un poco porque pasa demasiado tiempo en una habitación y muy poco en otra, pero en general no representa un problema. Con una sola carga limpia todo mi departamento de 3 recamaras y dos baños, así que no me es necesaria la función de autorecargarse de otras más caras. Le es difícil encontrar su base de carga si está en otra habitación, así que hay que llevarla manual o esperar a que regrese a la habitación principal para mandarla a su base. Me gusta que se mete por donde cabe y busca entre las sillas la manera de entrar abajo del comedor. Súper buena inversión y muy recomendada. Compré una para mí y una para mí mamá. Cómo referencia, la pague en 5mil durante el buen fin.

Well we originally was told about this device from my sister. We never owned one before but know many people that owned one. This unit does mopping and vacuuming. It worked wonderfully learning with each pass or total cleaning. we could purchase a separate docking station for the downstairs but we ended up purchasing a second. Which all connects to the same account on one phone. The floors look great and we have it programmed to clean twice a week. I have family with young children and pets and they do there's once a day. I highly recommend , simple to use, cleans well with cleaning solution or just water. Reasonable price for what you get. Strongly recommend if your in the market.

Amazingly clean floor. Maid or any himan cant do such a powerful cleaning. Wish they had mopping function too included in the same. Robo with mopping and brooming both are very costly so i opted for this one. Loved it. No hassel cleaning, juta need to take care of long hairs etc. Ut tangels the brushes. Hppy with extra brush, batter for remote and eztra filters provided by eufy. They are increasing price and usually not available due to covid pandemic. Bought a little early so got it.

Update, May 15, 2024: Today the new battery lasted 100 minutes. Update, May 8, 2024: I sent an email to the manufacturer explaining the battery situation and they sent me a new battery under warranty. Very poor manual because of very small illustrations which are not the same as on the robot, plus does not explain how to delete a setting. A fairly good robot though, cleans well but tends to remain in larger rooms, it starts in the living room of 1,500 sq.' apartment, manages to find the bedroom, but once it exits the bedroom it does not go back to finish the bedroom and washroom. My fix for this is to put it in the bedroom and close the door and let it run until it finishes the bedroom, then take it to the living room. It does not clean near the charging station. Very quiet, bumps very gently. When it is working beside you, you can still hold a conversation. It is very easy to clean the waste bin, roller, wheels and filter. I clean it and wipe off the machine each time I use it, which is twice a month. I find this vacuum very easy to use and clean. It usually runs for about 1.5 hours, then recharges. For $200.00 Canadian it is an okay value. It does not have the headaches and problems associated with programming using cell phones. I understand why manufacturers went that route, but it isn't good. TIPS: do one room at a time. The reason is that the robot learns the room and wastes less time learning multiple rooms. Give it plenty of time to fully recharge between uses. CLEAN IT, CLEAN IT, CLEAN IT after each use - remember to do the wheels, they pop out so easily.

En materiales se nota la calidad del plástico, todos ve resistente y los componentes se ven bien hechos. La limpieza está en varios niveles superior a las que traen mopas giratorias, limpia mas profundo y se va autolimpiando mientras funciona. La potencia de aspirado excelente. Tenia una roborck mucho más cara que esta y dejó de funcionar al año, y comparándolo con la c28 creo que está mejor en calidad y funcionalidad. Desventajas: Los tanques de agua son pequeños, asi como la bolsa de aire, nada de que preocupar solo cambiar un poco mas frecuente el agua, depende del uso. La aplicación es sencilla pero cumple con todo lo que se requiere.
