eufy 11S MAX Robot Vacuum Cleaner, Super Thin, Quiet

As a neat freak, this has been one of my favorite purchases recently. Hands down. No doubt. Our house has seriously never felt so clean. With four boys coming and going, plus a cat, plus my wife and I both working out of the same house, this place gets dir-r-r-r-ty! But now, I just set this little baby up and get it goes to town. Note: the first several times that we used it, the machine's debris holding chamber was LOADED. We ran it until the battery died (and it returned to it's charger automatically), emptied it, and then ran it again as soon as it was fully charged. But each time that it ran, it was completely full! Every single time. None of us can believe how dirty we were living. Note #2: We now take it upstairs to do a deep cleaning there. We had a little bit of a learning curve to make sure that all of the electric cords and such were off the floor. (They untangle easily, btw, if you forget). My son with the cat had a room that used to smell terrible... it smells almost normal after we ran this several times through there. And the volume of cat hair that this thing picked up is crazy amazing. Hair that we didn't even see. I didn't know cat hair smalled badly, but it must've. Room smells pretty decent now (not perfect - there still is a smally boy living in there)! Note #3: We keep a pretty clean house. That is what is amazing about this thing. It makes it really clean. Note #4: After the first several runs, make sure that you clean the roller brush. It will make a difference. The tool that comes with the unit that looks like a comb does a great job. If you get hair or thread or similar wrapped around it, use the handy dandy letter opener-style cutter to easily and safely clean it out. The blue parts on bottom around roller remove easily for deep cleaning. Do it! Easy and worth it for better future results. Note #5: Does all types of floors really well. We have ceramic, vinyl, short carpet, marble, deep carpet - all on the first floor of our house --- NO PROBLEM for Eufy! It moves with ease between them all. Note #6: Problem areas? We have a screened in porch that has a door that allows tiny little leaves in under the door. I'll just set the Eufy out there and forget about it. When I see it again, the machine has run out of juice and the floor is perfectly clean. Or my basement office. Set it in there at the end of the day, close the door and forget about it. In the morning, the floors are clean and the machine is sleeping where it ran out of power. I take it back upstairs, empty the cannister, and put it back on the charger. Last note: It gets in tight spaces. It cleans edges beautifully. It spends more time on a room than we ever would, so I guess that is why it cleans so well. It gets under most of our furniture. Around most of our chairs. And oh - I almost forgot - this vacuum is SO-o-o-o quiet. With our upright, you can't hear yourself think. With this thing, I can be do my work uninterrupted. Disclaimer - I have wasted a lot of time just watching machine in amazement and awe! Thankfully I can now walk away from it - although the 7 sessions with a therapist to get me to break the habit were a pain. ;) I highly recommend the machine - if you couldn't already tell! I came back on to Amazon to buy a unit for my in-laws and saw the opportunity to avoid my job for a little bit to write this review! Funny, but I am glad that I did. This little fella is totally worth it. If you are thinking about which brand to buy, you can't go wrong with Eufy. Kudos to the manufacturer and development team! Note to manufacturer: Can you please develop a machine to automatically climb and clean stairs (cook, do toilets, do laundry)... ? People, you are going to love this vacuum!

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 got this product 20 days ago and it’s great to use, the suction power is good, it’s deep cleaning mode makes the house super clean, it mapping the house super fast, just that it makes a lil noise while emptying the dust after cleaning. Also it has got some scratches from bumping into furnitures. The app is quick and user Friendly.

EDIT: It's been a while now and Navi runs every day! We love it and so does our bird. She squees at it until she can ride it and then she kisses the blue light as it bumps around the living room. (Under supervision, of course.) She looks forward to it every day. As soon as it beeps and starts moving, she starts shuffling and demanding someone put her on it! As they say, "The future is now, old man!" I am not a person who likes to clean. I will avoid it at all costs and do a shoddy job once I do get around to doing it. That said, I have a terrier mix and a long haired chihuahua mix that constantly shed. They also constantly go in and out the back door to our yard which floods and is surrounded by trees so they are always bringing in dirt and leaves on their fur! On top of that, I have a bird who loves to throw food and little kibble bits over the top of her cage just to watch it roll away and under the furniture! Well, a few weeks ago, I had enough of it! I started looking for a modern technological solution and I found it here with Eufy! Yes, I'd looked at Roomba but so many people complained about it being loud and others mentioned how you were really paying for the name brand. I'm not about that life so I looked at alternatives. We found Eufy and saw all the great comments and reviews on it. Hubby and I were skeptical but finally, we pulled the trigger. And oh boy, we could NOT be happier! Because the house was messy, when I first ran it, it was needing to be emptied often and so it reminded me to tend to it often! I ended up naming it Navi as an ode to that ever helpful yet incessant fairy from Legend of Zelda. Navi does not beep so much nowadays but boy does she pick up the mess! She has made the floors so clean, I can just come after her with a wet mop and the floors look better than they have in years. Only thing she doesn't get is the impossible corners of rooms and areas she just literally can't wedge in width-wise. I don't begrudge her that. I just sweep those bits out myself. But she runs up along the walls, using her little brushes to sweep the edge there until it's clear of debris. No marks on the molding there either. Very gentle. She gobbles up the leaves and flecks of dirt that the dogs bring in and it's so easy to just mop up the mud when it rains as she literally takes care of everything else! She even circles under and around the birdcage to pick up all the pellets and seed shells! What's more, she will also go under the furniture to get the bits that roll under there too! I have seen some people had trouble with the drop sensors. We had a slightly similar issue on our black tiles and black rug but we covered the drop sensors (we live in a 1 story house with no way for Navi to fall off anything!) and haven't had a problem since! Another great thing is she is sooo quiet. I can watch TV and hold a (slightly raised voice) conversation with my husband when she's going under my feet and cleaning out under the couch! Yes, she's that quiet, it's crazy. I read stories about the Roomba scaring people half to death when it starts up in the middle of the night because it's so loud. I run my Navi in the day and night (we work crazy night schedules sometimes) and she never wakes me up. If anything, my bird gets turbo excited about Navi running around and the BIRD's squealing lets me know Navi is running if I'm still laying in bed. I can't tell you how satisfying it is to be able to sleep in on the weekend and still know that house chores are being done! The only thing we needed to do was make sure the dog toys are picked up before going to bed and make sure any wires are off the floor because she can get snagged on them but it's just good practice to do those things anyway! The battery goes for a long time if you don't put it on Max and I'm always surprised by how much debris Navi collects by the time she returns to recharge herself. She's also really good at that mostly, finding her way home. The only time it seems she can't make it is when we leave the doors to the bedrooms in the back open. Sometimes she struggles to find her way out of the back bedrooms, down the hallway and into the living room in time so we've just taken to doing the back bedrooms on different days and shutting her in there while she does her business and then remove her when she's ready to recharge. She gets around the living room, hallway, dining room, kitchen, bathroom, and the closest bedroom on regular days just fine though! But other than that, she is just perfect. We no longer have a dust bunny farm and it's so easy to clean out her container, clean offer her brushes and set her back to work, I don't think I could live without Navi now. I hope she runs for a long, long time. We run her every day and I still can't get over it. Just last night, she kicked on and rolled past me as I was getting ready for bed. I watched her go, toothbrush in my mouth as she headed into the kitchen to begin her day. How cool is that? I'm about to go to sleep and there's this little robot, quiet as can be, rolling out to sweep up the little bit of flour I spilled earlier that day. Maybe I should've named her Dobby. But whatever, I love her. Thanks, Eufy!

I want to start with the things that aren't so great. First, it took over a week to arrive. It being Amazon's choice and coming from amazon not a 3rd party, I didn't think it would take that long. A product that has 40k reviews should be on hand. That's because the reviews are for several different models this review is for the 11s max so make sure the review goes with the machine you are looking at. That being said the video shown shows two rotating brushes on the front. That is obviously a different model because mine arrived with one. My I robot spoke words when it was hung up, check side wheels, charge... ect. This only beeps and has lights you have to interpret via the booklet but it's pretty easy to find out what's wrong with a robot vacuum so no biggie. I didn't want a mop combo because most reviews for those said it's nothing more than a washcloth that drags dirt and they often leak. And I don't want to use an app. I want to put it down and hit the button. This let's you do that but it has a remote too and you can set a timer. It is soooo much quieter than my I robot. I kept checking on it to make sure it was still running the first day because I couldn't hear it. The old vacuum literally woke the kids and they couldn't hear the TV once they were up. This one is lower profile and fits under all my cabinets instead of wedging itself and ruining it's wheel like the I robot did. It doesn't seem to be trapped any longer than the old vacuum under 4 post chairs. It figures it out. I'm not sure if it's mapping. But I will let it run longer because it's so quiet it doesn't bother me. I love the circle spot clean button. I drop it in front of the door for leaves. The bin is the same size as the other. I empty each time so it doesn't bother me. It's picking up well. Overall after waiting so long worried I would get something I hate, I am really happy with this and the price! I hope it lasts as many years as well.

This Robot Vacuum is really good for the price. I think the only thing that has annoyed me was that it gets trapped under the fridge or it will get on a chord or something but as long as it has a clear path it works really well. You can program it to clean at certain times of the day, I have it set to clean at 1pm for example, and you can control where it goes. It has a neat spot cleaning mode that I havent really used much but it would be great for a large open area because it goes in a perfect circle wider and wider to cover the entire area. Definitely purchase if you’re looking for a pretty decent vacuum that will get all the dirt off your floors that YOU WOULDNT EVEN NOTICE WAS ON THE FLOOR. I swear it picks up a lot and I have 3 cats so this is a game changer. Definitely sponsor me for this review cause i write NO reviews and i specifically wrote one just for this item.

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.

I am really liking this vacuum overall! Here is a breakdown of my experience so far: Mopping Performance: The spinning roller mop is a huge improvement over the dual round pads on my previous robot (X10 Pro), which used to leave annoying round streaks. This design cleans much more uniformly, and it seems to use less water while still leaving the floors looking spotless. Navigation & Obstacle Handling: It maneuvers around my bar stools significantly better than my X10 Pro, which constantly used to get stuck in that area. Setup: Setup was really easy right out of the box. Water Tanks: The clean and dirty water tanks are noticeably smaller than the ones on the X10 Pro. I am still undecided on how I feel about this trade-off, though it hasn't been a dealbreaker yet. App Experience: Surprisingly, it required downloading a different app than the one I use for my X10 Pro. That said, it was a relief to find that I was able to connect both of my Eufy robot vacuums successfully to the new app. Accessories: My only real complaint is that it did not come with any extra replacement accessories for future maintenance.

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.

Eufy Life is developing a branding that may one day outshine Anker. I splurged the extra few dollars for the white RoboVac 11s. It's better and I'll tell you why. This thing crawls into some horrible, dark, dusty places, where centipedes go to die...and it comes barreling out like Indiana Jones, tenacious and undaunted. The dust clings to the shiny plastic shell like cobwebs on Indy's fedora--badges of honor from a well-fought victory. After some time, the machine looks filthy. This would be ten times worse on a glossy black machine. I think white was the best colour choice. Take note EUFY: Military urban camo or shades of grey-white tiger stripes would be the best choice for this dust eating beast. (RoboVac Decal sticker kit coming soon!) The black one is shown gobbling up granola in the promo pics, but the white one is also shown with a dustbin full of M&Ms so I wanted the one that could find me candy! Yes, the cleaning pattern isn't super smart but it is smart enough to get the job done. On Auto Clean mode, it does follow edges and navigates around wall edges and legs. It climbs up onto our low-ish pile carpet and even climbs over the folded over corners of our cheap Walmart hallway carpet (after it turned and folded over said carpet). It sometimes puts the carpet back and it sometimes leaves it on a jaunty angle. The standard vacuum fan setting is SUPER quiet (like a microwave hum, like one review said) and does not freak out our sensitive cats. They sit around and watch it gobble up their hair on the floor. The max setting is not much louder but I'm sticking to standard until it gets worked in and the cats are used to it. The loudest part is when it gallops over the 8" ceramic tile floor in the kitchen "clack clack, clack clack" almost like horse hooves on a cobbled street. The big rubber drive-wheels are quiet but the front and back rollers are harder and noisier. Battery: If it's an Anker battery then it's a good one. I've never had it run out of juice. I run it myself after checking for loose cables, spills or cat barf. After what seems an eternity (an hour or more) of cat videos and product reviews on YouTube, the RoboVac is always still running so I send it home. I swear Doc Brown designed it to run on dirt and hair fusion. It manages to find its charging base even though it is tucked under a desk without the full recommended 1 metre clearance on each side. It gets close and then adjusts its heading. One time it missed and it just turned around and tried again and totally nailed it. NEEDS MAINTENANCE! This is not a lazy slob device--time saved vacuuming requires time spent emptying the canister, changing and cleaning brushes, filters, finding and rescuing the robot. The mesh fliter catches most chunks--Install carefully and keep filters clean and your Robot will keep max suction. Get multiple main and side brushes and big packs of filters, swap it all out Congratulations for reading this awesome review so far. Here is your March 2023 update: bought December 2018, before COVID, before kids. 4 years in, Robo is struggling to keep up with the kids--rogue cheerios, flakes of play-doh, crushed goldfish crackers, tracked in dirt... Advice: don't let the kids touch it/ride it, drag it around. Don't shove it out of the way, and don't watch it work. Robovac works best when left alone in a room/home floor that has been cleared of hang-up obstacles (wires and 2.5cm lumps/books/toys). It will bounce around and will clean everything... eventually ( by the end of the cycle or the next time it runs). If it regularly gets stuck somewhere, change that area so it doesn't. Aside from regular cleaning and changing filters, I have had to replace one side brush motor, and one of the drive wheels has a slipping connection to the motor. Both of these are gear issues from rough handling. $20 to $50 DIY fixes using online videos. Battery is original.

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.
