Dolphin Nautilus CC Plus Wi-Fi Automatic Robotic Pool Vacuum Cleaner, Always Cleaning, Never Charging, with Wall Climbing Scrubber Brush, Ideal for In-Ground Pools up to 40 FT in Length

Best robot I've had so far. I've had two others the same type and they lasted about 10-12 years each. This one is a lot better in performance. All robots do a decent job on the floor and sloped sides of a pool. When it comes to the vertical sides and the waterline, that's where you separate the men from the boys. The Dolphin climbs the walls better than the others but then it does something I've never seen in another robot. It turns sideways and runs along the waterline. Sometimes few a few feet and sometimes for 10-15 feet and even turns around the 90 degree corners. The one fault it has on my pool is that it gets stuck on the main drains. I was going to return it but then I found a solution from Polaris. They make a cover for the main drains that allows the robot to glide over the smoothly and still have the drain workin. They weren't cheap but they work perfectly so far. With the cost of the robot and the two drain covers it was still hundreds cheaper then my last robot One additional feature that I really like is that it doesn't allow debris to flow back into your pool when you remove it for cleaning. Great feature. Can't sp-eak about reliability as I've only had it for two months.

We have a 40x15 pool that is 5 feet deep all around with stairs in two corners (one big stair in one corner and four smaller stairs in another). We have a motorized pool cover that is on most of the time so we don't get a ton of debris... but when using the pool stuff blows into it, so we do need to clean it. Got this vacuum two days ago and setup was very easy. Dropped it in the pool and watched it for a while and it seemed to be doing well cleaning the bottom and sides, but then got stuck in one spot on our stairs for a half hour. So you have to be watching it and move it to get it unstuck. Used it the next day for another hour. Started with the pool cover off to watch it, and got stuck again multiple times for long periods of time! Then, with the pool cover closed, this thing actually sucked up the side of the wall and then sucked itself onto the underside pool cover and was going back and forth along the underside of the pool cover! Crazy! That's not what it's supposed to do! I called the company's customer support (in India) and that lady said these robots are not made to clean or climb stairs! I explained that most pools in the world have stairs, so that didn't make sense! I get it if they don't clean the stairs, but getting stuck on them? Then she said it's not supposed to clean the underside of the pool cover. That I should return it to Amazon and get another one. Like the new one isn't going to do the exact same thing??? After the two uses my wife said... nope, this isn’t going to work. We need to be able to use it with the pool cover closed (so more crap doesn't blow into the pool while it's being cleaned)... and we can't have it getting stuck repeatedly in the same spots and sit there having to babysit it. Oh well... Guess we will try something else.

The Dolphin Nautilus CC Plus has been a great addition to my pool maintenance routine. It does an excellent job cleaning the pool floor and walls, and I love being able to control and schedule cleanings through the Wi-Fi app. It saves me a lot of time and keeps the pool looking clean with very little effort on my part. Setup was simple, and the filter is easy to remove and clean. Overall, it's a reliable and effective pool vacuum that has exceeded my expectations.

Game-Changer for Heavy Debris Pools – Excellent Product, Outstanding Support I’ve had the Dolphin Nautilus CC Plus Wi-Fi Robotic Pool Cleaner for over a year and a half now, and it’s been an absolute game-changer. This unit is a total workhorse—and in my case, a lifesaver. I have a massive Jacaranda tree that drops what feels like millions of tiny leaves and sticks into my pool (which is not screened in), and this cleaner handles it all with ease. The small twigs that used to be nearly impossible to remove with a skimming net are now gone without lifting a finger. It’s incredibly easy to use, and even convinced my pool contractor—who once thought robotic cleaners were a gimmick. Now, after seeing mine in action, he recommends it to all his clients. I use it twice a day, and only recently (about two months ago) did I start having a couple of minor issues. One of the treads would occasionally pop off, usually on the steps, but it was easy to reattach and never a big deal. I also had a problem with the control box—the unit wouldn’t complete a full cleaning cycle. I contacted customer service and was genuinely impressed. They responded quickly, issued me an RGA number and a return shipping label. I covered shipping to them, and they covered the return. They estimated 1–3 weeks for turnaround, but I had it back in just 5 days. Not only was the issue resolved, but the unit came back completely refurbished with new treads, a new hose, and a new power supply—possibly more, but that’s what I noticed. It’s now back at work and running better than ever. After 18+ months of consistent use, I can say this is not only a reliable and powerful cleaner, but it’s also backed by a company that truly stands behind its product. Friendly, responsive, and efficient service makes all the difference. Highly recommend—especially if you deal with heavy debris. This cleaner is worth every penny.

2nd Update: After 2 new power supplies (2nd one they sent was a new updated version) I still cannot connect and now the cleaning unit is not working properly, maybe due to all of the changing and testing they had me do, I don't know. But it will just move forward then backward about 3 feet over and over. Finally they decided that needed to send it all back to them! They sent me an RMA and instructed me to box it all up (all original pieces) and send it to them by UPS. I had to pay for the postage there ($75) and they pay for the return trip. Not happy about that but what'cha gonna do? Anyway, they kept it about 3-4 days and sent it back. I plugged it in and it immediately connected to my wifi and phone app. Works perfectly now, and I have no idea what they did. After a month, it seems to still be working great but I'll keep my fingers crossed! Update: After 8 months of fairly good use, it decided to no longer connect to my phone app. After multiple tries I decided to contact their customer support. They responded within a day or two and we went over some different steps to get it to connect but none worked. It was escalated to the next support level where they decided to send me a new power supply (this contains the wifi and Bluetooth receivers). I received the new PS in about 4 days and then began to try again. I tried 2 different Android phones and a new IPhone but none would connect to the new power supply. Now that's where I'm at, the cleaner does fine if you start it manually but I paid extra to get the wifi model so that I could create a daily schedule that would run the cleaner whether I was at home or not. I still believe that this is decent cleaner but something has gone wrong with the connection. Maybe an app update that messed it up? Who knows? I'm waiting for customer support to return my email about what they want to do next. I will update this review. OK, I've been researching for a robotic cleaner to replace the basic Pentair Racer that came with my pool. After 3 years it just wasn't doing the job. I decided on a corded robot because I know from experience that rechargeable batteries will go bad after the 1st year or so, plus corded robots can stay in the pool over extended periods if necessary. I settled on the Dolphin Nautilus CC plus wifi mostly due to its name and reputation. Now, after unpacking and setting it up, I will give my initial opinion. Very easy to unpack and set up, only need a very short start-up guide to get it cleaning. Put it in the water, plugged it in and pushed the button, started cleaning after about a 2 minute warm-up. Downloaded the app and set that up in less than 5 minutes with no hang ups or issues. App connects to the robot easily. Now with that said, I'm not sure that the extra money for the wifi app is really worth it. It only has the single, embedded cleaning patter, so you can't select other patters like some other robots will allow. The only thing that you can can do is schedule it for multiple days, but they suggest that you remove it from the pool after each use. I guess that if I'm going to be gone for a week or 2, I can schedule it to keep the pool clean while I'm away, and just take a chance that the extended pool time doesn't harm the robot. I wish that this had a larger filter basket. It is very thin and won't hold much once the leaves start falling this fall. I'll probably put my old Racer back in for that and save the Nautilus for when there will be less clean up. But we'll see! I'll watch this thing over the next few weeks and report back on how things are going, but as of the first day, I think that it was a good buy. FYI- the manual (along with several other reviewers) indicate that there is supposed to be 2 sets of filter baskets included with this unit, 1 set of fine and 1 set of ultra fine. I only received 1 set with the "fine" filters. I sent messages to both the seller and the manufacturer for assistance. We will see how that turns out!

I need to start by stating I have had this unit for 17 days. Ordered on March 2nd, received on the 4th and used for the first time on the 5th. Fast forward an entire 11 days later (4 total clean cycles) and the unit fails to turn on for its 5th usage. Reviewed the manufactures troubleshooting procedures, but still no resolve. Proceeded to spend the next morning on the phone the manufacture’s customer support of which ended with them wanting to repair the unit. I’m not one for writing reviews (although I appreciate those that take the time as I certainly read them), but I’m compelled to do so today. The fact that the manufacture’s response to my issue was “well you had one successful cleaning cycle so we will only repair it” is appalling in my opinion. This isn’t the most expensive unit on the market, but also isn’t pennies on the dollar either. The fact that a manufacture doesn’t stand behind its products following a single usage and requires customers to jump through hoops as if it was a day at the circus tells me everything I need to know about their “warranty”. To set the stage a little clearer, this is our 2nd Nautilus CC Plus. The first was without Wi-Fi and lasted just north of 3 years before the power supply stopped working. After replacing the power supply, we got one additional year out of the unit before it stopped working again. Replaced the blue cable but still didn’t restore the function. After 4 years and $270 invested in replacement parts I came to conclusion I had gotten all the life I was going to get out of our first unit. When the Nautilus CC Plus is operational, the unit works wonderful especially with the fine filters. Where I draw the line is when a manufacture doesn’t stand behind their product after less than a month of use. After 90 minutes of back and forth, I’m waiting for a supervisor to approve a replacement. I’ll be sure to provide an update, but for all my pool owners out there may this serve as a warning. I take pride in my assets and although the pool was more for the wife and kids, I attempt to use the best products on the market to ensure its always ready for their leisure. I now question if Maytronics and their Dolphin should be part of that list of products. Update: The manufacture did offer to replace the unit all together vs. repairing it after two weeks of use, but their lack of communication was on full display again. They sent me a form to be shipped with the return product as well as the shipping address. I proceeded to USP that day to get the package returned, frustrated with the fact I was $114 out-of-pocket to ship it back, but they made it clear they would not ship the new unit until the current one was in their possession. Fast forward two days later, I receive another email from the manufacture including the same return form, shipping address and this time a prepaid FedEx label. After another frustrated email, they confirmed the error was on their end and the original email should have included the return label but their system failed to attach it. They then asked for my shipping number so they could track the unit to dock and then process the replacement. No offer to compensate for my additional out-of-pocket expenses for their error and although the package arrived on Friday the 21st before 10am, no additional communication has been provided regarding the status on my replacement.

After reading literally hundreds of reviews, I purchased a cordless pool cleaner - it got 35 five star reviews on Amazon and none less than that! I was impressed. I turned off the pump so it wouldn't get stuck on the (raised) drain. It got stuck. It got stuck on the stairs as well. In both cases, it got free after some effort. The problem with these cordless cleaners is that they are power limited because of the battery and freeing itself gobbles up energy. The cleaner also struggled to get up the walls. Plan B was to purchase the Dolphin Nautilus CC Plus with WiFi, based on the reviews. In choosing a cleaner I considered the size and shape of my pool because it became clear to me from the reviews that one size doesn't fit all, i.e., a great cleaner for one pool might be terrible for another. I have a lap pool that measures 45 x 7.5 feet, is about four feet deep throughout, and has stairs on one end. I have used the Nautilus CC Plus three times. My pool doesn't get a lot of leaves or debris so I don't need a large basket. The provided baskets are more than ample. My biggest problem is the junk that collects at the waterline so I had hopes that this robot would be helpful. The Frequently Asked Questions, included in the documentations, answered the question, "Does my Dolphin clean the waterline? Answer: The cleaner is designed to climb the walls, but does not reach the waterline". See attached video. This does exactly what I need it to do. Obviously, they need to hire a better marketing person. This robot does not get stuck over the raised drain with the pump running and drawing water from the pool. It climbs the steps (seems to love them) but will occasionally get stuck on a step or in a corner, but it releases itself, and because this is tethered you don't have to worry about draining a battery. It also has considerable power and thrust for climbing the walls and stairs due to it drawing current from the power supply. My only concern is the wear and tear on the paddles/fins, whatever, when it gets stuck as sometimes they keep spinning against my PebbleSheen surface before releasing. Time will tell. I have not been able to pair it with either my iPhone or iPad but I have contacted the company in hopes that they can solve the problem. If not, this is not a game changer for me. Finally, just put it in the water and walk away. I found myself getting stressed and yelling at it, "Why are you attacking the stairs? You haven't touched the other end of the pool? Why do you keep going over the same area?" I thought that this was supposed to be smart and map out the pool but it didn't appear to be doing anything intelligent. I finally went away and when I came back it had covered the whole pool and picked up everything. The robot does not have a memory so every cleaning is a new experience, like a goldfish doing a swim around the fishbowl and forgetting the last pass. Cleaning the filters is a breeze. See the photo of the debris that it picked up on its first use. You can spend a lot more for a pool robot but at this price I highly recommend this cleaner. Update: I have now had this robot for a while and am still very happy with it. The customer service has been excellent. After a few emails back and forth about the WiFi not working they decided to send a new power supply. That fixed the problem. With the Dolphin app on your phone you can turn the robot on and off and schedule it to clean every day or two other options. Unfortunately, you cannot control the robot. This would be useful as it did get stuck a couple of times, and rather than wait for it to free itself (it was taking a long time on the raised drain or step) I decided to free it manually. Perhaps in the future they might add more capability to the app so you could get the robot free without having to intervene manually. I would love to be able to tell it to reverse when it headed to my steps. In conclusion, I stand by my recommendation about the efficacy of the robot and now can add that they have great customer service. Update 7/24/24. The customer service person suggested that I moved the floats closer to the robot, which might alleviate the robot getting stuck on the stairs. I moved the closest one and this seems to have helped. I just purchased pleated filters, which are for finer debris and not included when you buy the robot. I was skeptical but I thought that I would try them. I first cleaned the pool with the filters that are supplied. Immediately afterwards I put the pleated filters in for another cleaning cycle. They picked up really fine material that the standard filter missed. When I rinsed the pleated filter it looked like mud was coming out of them. So these really work. I would not recommend using them without using the coarser filters first because some large particles get stuck in the pleats and not all of them will rinse out easily with a hose so you have to manually separate the pleat to get them out. That being said, there were only a few of these particles so it was no big deal. The robot continues to work very well. I always remove it from the pool when done as I've read that the robot and cable will deteriorate faster if you leave it in the water, however that's for a very long period of time so it's up to you if you want to leave it in the pool and have it come on a particular schedule. Update: June 5, 2025. There was a lot of debris in the pool when it was opened this season. The CC Plus did a great job but keep in mind that if there is a lot of debris you need to empty it more often, i.e., don't let it run the full two hours. After several cleaning cycles I was able to run it the full time. One thing that is aggravating is recoiling the hose. It has a mind of its own. If you start to coil it clockwise it's OK for one or two coils but then it decides it doesn't want to go in that direction anymore. Grrrrr. If anyone has any suggestions I would appreciate it.

I purchased the Dolphin Nautilus CC Plus Wi-Fi Automatic Robotic Pool Vacuum Cleaner in June 2025 for my in-ground pool. For the first six months it was fantastic. I ran it weekly through November and it kept the pool sparkling clean with almost no effort. The wall-climbing scrubber brush, strong suction, and scheduled cleaning via the app made pool maintenance easy and enjoyable. Unfortunately, when I tried to start the unit again in February 2026 it would not power up properly. I contacted Dolphin support and was simply told to ship the robot in for repair — no troubleshooting steps were offered. I paid $163 out of pocket to send it to the authorized service center. After two weeks they returned it. The vacuum now runs, but the Bluetooth and Wi-Fi features are completely non-functional. I am stuck using the old physical control box and can no longer schedule cleanings, which was one of the main reasons I bought this model. I reached out to support again about the connectivity issue. For over two months now I have been sent through the same diagnostic steps repeatedly with no resolution. They will not allow a phone call and are now asking me to ship the unit back a second time — again at my expense — so they can “look at it again.” The robot performed very well when it worked, but the repeated repairs, shipping costs, and lack of meaningful customer support have been extremely disappointing for a premium product. I was expecting far better service after spending this much money. I really hope the Dolphin team sees this and helps us reach a fair resolution so I can once again have a reliable pool cleaner I can recommend.

It really cleans well and has a good reach too. Able to navigate our odd shaped pool and even cleans the sides though it is quite random in how it goes about cleaning. It’s easy to wash the filters and operate the machine. Highly recommended.

Loved the Dolphin and bought and use the wifi connection. We have a 12 foot deepend pool and 4 ft shallow - 40 feet long, 20 feet wide. It worked amazingly! Pool is spotless. It does take a bit for the Dolphin to do the entire pool. The wall cleaning is really cool with absolutely no problems in climbing. Stairs are ok...sometimes forgets to to the top stair but that's ok. It is pricey but well worth it. Saves a lot of time vacuuming and our pool sparkles.

I don't normal do reviews, but this product is needs one. I bought this in May 2023 and used it from June-September for 3 months. It was working fine, it did not clean the pool well but it did the job. This year, we used it for two weeks at the end of May. Suddenly stop working. I followed the instructions on the website to ensure it was clean, no debris. I reset the Vacuum, still not working. I'm disappointed in a few things. The cost, it was very expensive and they are suppose to last for 5-8 years, this lasted 4 months. The customer service is not great. No one local to fix it and no one local you can send it to. please consider this when buying this vacuum, it does not last and if anything breaks down there is no help to fix it.

Had a polaris 955 for 4 years and the motor died. Opted to buy something else and went with this model. Says it does do water line but it does, just not everywhere. Cleans nicely and seems better and faster than the polaris. Thought I'd miss not having the caddy but it not an issue. The app is fine. Installed and set up without an issue. I have a mesh network at home. The app is pretty basic but meets my needs. I don't know why there's an option to schedule this or any others when they recommend not leaving it in the pool. Pretty sure that's what caused my last one to fail. I store I when not in use. Filters are east to clean. Only thing and it's minor, the polaris seemed to empty water quicker when removing. But am extra 30 seconds is fine. I don't miss the remote, nor steering ability either. Have a 34x16 free-form inground. Will follow up at the end of the season.

I picked this up when our polaris pool cleaner died. That cleaner was perfect for 4 seasons until it failed...not good enough for an expensive device. I thought I would try this one...the CC plus... and it was on sale so that was a bonus. The first time I put it in the water I did not correctly close one of the filter baskets and the propeller was getting jammed with leaves and it obviously did not clean the pool. After I fixed it and cleared the propeller I tried again and it worked extremely well! Other reviewers have said it does not climb walls. In fact it does. It also will move horizontally across the wall and clean the scum from the waterline. The cord does not seem to tangle after 5 cleanings (the polaris was annoying for that and always turned the same way). We have a large (41x25) irregular pool in the forest surrounded by trees and the pool needs a vacuum just about every day or two at the least. The 30 month warranty is better than competition...I am hoping for 8 years+.
