Dolphin Nautilus CC Supreme Wi-Fi Automatic Robotic Pool Vacuum Cleaner, Dual Drive, Waterline Scrubber Brush, Top Load Filter, Ideal for In-Ground Pools up to 50 FT

After purchasing and testing three different pool robots in my 20’ x 40’ rectangular vinyl pool, here are my thoughts: 🥇 1st Place: Dolphin (by far the best) The Dolphin completely outperformed the others. On its very first cleaning cycle, it picked up all of the fine debris that had been sitting in the pool for over a month despite repeated cleanings with the other two robots. It cleaned methodically, covered the entire pool, climbed the walls reliably, and left the water noticeably cleaner. If your priority is actually getting your pool clean—especially fine dirt and dust—this is the one I’d recommend. 🥈 2nd Place: Aiper For a cordless robot, the Aiper was surprisingly good, especially considering the price. It didn’t clean as thoroughly as the Dolphin and its battery life resulted in a shorter cleaning cycle, but it still did a respectable job. If you’re specifically looking for a cordless option and want good value, I’d recommend it. 🥉 3rd Place: Beatbot Unfortunately, the Beatbot was the biggest disappointment despite being the most expensive of the three. It consistently missed large sections of the pool and struggled to pick up fine debris. Even after multiple cleaning cycles (and even a replacement unit), it left behind the same dirt that the Dolphin removed in a single pass. It also failed to climb the walls effectively in my 20’ x 40’ rectangular vinyl pool, often slipping back down before reaching the waterline. For the premium price, I expected much better performance. Bottom line: If cleaning performance is your top priority, the Dolphin is worth every penny. If you want a cordless robot at a more affordable price, I’d choose the Aiper. Based on my experience, I would not purchase the Beatbot again.

The robot does a pretty good job (not great but I saved me vacuuming most of the pool). What is very unfortunate is the software and customer support in relation to this. When the app stopped functioning I contacted Maytronics. I was a good sport and jumped through their hoops, having me reinstall the app 100 times, moving my home access point around to get better signal. I knew the entire time my WiFi wasn't the issue - the software is just horrible. I'm not nitpicking either - I used the robot for a month dealing with the unreliable connection and put up with it because the robot was helping me clean. But now it won't connect at all which makes the robot useless (no manual override). Their support has since stopped responding to me completely, 6 weeks after I bought it. I really wanted to like this robot because it does what it should. The company service is just horrible though. One other thing that customers should know - and I don't know if this was by mistake - but when dealing with their support they revealed some things about my home network that I found creepy for them to know about. The controller apparently relays all sorts of details about your home network back to them and they store it for who knows what purpose. But as a privacy concern, I think everyone should be aware of this.

I bought this a month ago after researching a set of options (including the Dolphin Sigma and various other sub-$1000 robots). I wanted to give it a few weeks before I wrote a review and try it out, and I have to say I'm glad that I bought this (even at the higher price). Getting going was pretty easy. Could this have used a better user manual? Sure, but I had it up and running in about 30 mins. I wasn't sure how to "diagonalize" the float handle out of the box (see below) but just tried it at max diag. The controls (on the app) for setting a cycle, monitoring progress, etc. are fairly simple to use, and complete enough for everything I need to do. It is true that the "drive by app" feature isn't great -- it has a 2 second lag between command and actuation, but once you know that, you can get it to the place you want to go if you have a tough spot you want to hit manually. And you can start it from anywhere using your phone once it is tied into your WiFi, I start mine from the grocery store or wherever. In terms of cleaning, this thing is really pretty excellent, honestly my pool has never looked so good with so little effort, and this in the dead of winter when my pool is typically full of leaves, twigs, dirt, and other assorted muck. This robot has probably saved me about 2-3 hours per week (if not more) of sweeping and vacuuming my pool, which is a 25K gallon in-ground rectangle with some curve-y sides. the 2.5 hour cycle I have been running once every other day or once per day when I think about it and that seems to cover the entire thing. The robot climbs walls pretty effectively and does wall cleaning. There are adjustments for the "float handle" for putting that in place to make the robot either "stay high" on the walls for extended time or not. I have put it on the highest setting, and it seems to "crawl" along the water line (cleaning as it goes) for about 2-6 feet on this setting. But most of the time it spends on the floor of the pool with forays up walls. I think that makes sense. A couple of points on cleaning (pros): * Both sets of filters seem to pick up fine dirt/sand (which I have a lot of) and I can't tell much of a difference. * Leaves-twigs-etc -- gets all of that stuff no prob * Cleaning the filters -- really simple, easy, takes 3-5 mins every few days. Way way easier than I used to do (pole-mounted vacuum, cleaning the sock filter a pain). I could probably clean these filters once a week or two, but I get a lot of stuff in my pool so I've been playing it safe * Goes over raised drain covers no problem. I was considering the cheaper Dolphin Sigma model but there were some comments that that model would get stuck on top of the covers. I wasn't sure if this model would have the same problem, but it doesn't -- goes right over them. * It also climbs curved concave and convex walls. This surprised me, I thought the laws of physics would preclude a concave wall climb, but somehow it has enough traction/suction to do just that. Nifty. Balanced issues (cons): * The robot will climb up steps (especially the deeper ones that are more "table-like") and clean those. But not very often and not consistently every cycle. I find I have to sweep some fine grit off the steps about once every week or two * Does the robot get "stuck" sometimes? Yes, I have one particular notch area in my pool where it will get itself jammed (lightly) in that notch and not be able to back out on its own. I'd say this happens once every 4 or 5 cycles, and I just gently pull it by the cable back away from that area and it goes back to cleaning the rest of the pool. Unknowns: * Can you really leave it in the pool for extended periods of time? I have left mine in so far for about a week at a time, but I'm not sure still if this will cause any long term harm. I try to take it out of the water for a "rest" a couple of days at a time once a week. Not sure if that is a good idea or a waste of time. I just hope this thing lasts. If I can get at least 18-24 months about of it, will be a huge win.

This Nautilus CC Supreme cleans well and operates reliably but only is a moderate time saver for my weekly pool cleaning time. Bottom line is that instead of 1-1/2 to 2 hours cleaning the pool I spend about 1 hour manually cleaning the pool each week and about 30 minutes of robot setup+cleanup per week. What the CC Supreme does well - pick up dirt and leaves from the bottom of the pool and unattended cleaning. What the CC Supreme does less well - wall cleaning and waterline scrubbing. So I still have to manually vacuum and scrub my attached spa since it's physically separated from the pool and too small for the CC Supreme. I still have to manually vacuum and sweep my full length steps since the CC Supreme does not do steps. What I did find after several weeks of use is that the CC Supreme does not cover all parts of the wall well - especially rounded corners and eventually algae accumulates in the areas not covered by the Robot. So now I manually scrub all the walls of the pool - fortunately even for my 20,000 gallon pool that takes only about 15 minutes. With that the pool stays algae free and clean all week. Some good things: I have a pool cover that floats on the surface of the water and goes from wall to wall with no gaps. The CC Supreme works perfectly fine under the pool cover and even pokes up to do some waterline scrubbing. I usually use the robot every other day by itself under the pool cover. I remove the pool cover once a week to vacuum and scrub the steps and walls. and then run the robot without the pool cover. It's not very smart about how it cleans at the waterline and I notice that it will clean the same 4 ft section of waterline several times in one session and skip many other sections of waterline. The two filters are very easy and quick to clean and seem quite rugged. I'm using the standard (not ultra fine) filters and they do a good job of picking up leaves, debris, sand, and even filtering the pool water itself. Because the robot is quite heavy I highly recommend that you buy the universal caddy and premium caddy cover - which will allow you to wheel around the robot and controller and store them out of the way. The phone app works OK (takes an unusually long time to connect) but it's irritating that you can access the app data such as past cleaning information ONLY when the controller unit is plugged in and connected to the internet. If you disconnect the controller after use and store it away, the app data is not accessible. Given how I'm now using it, perhaps some of the less expensive Dolphin robots would have been just as good - just a thought.

Update (11/2022) Power supply stopped working today. I contacted Maytronics and they shipped me a preplacement immediately. All in all, I'm starting to like this company. Yes, I've had a couple of issues, but Maytronics customer service has really come through for me. I honestly think at this point it would be unfair to give them anything less than 5 stars. I'm very impressed. I'd also like to state that out of the previous 3 pool robots I've owned, this model, by far, is the absolute best. It's still performing like a new machine and my pool stays spotless with a standard cleaning cycle every 3 days. ************************************** Update (8/12/22) Okay...First of all, apologies for not posting a follow-up to this review. I honestly had forgotten that I ever posted it. Sorry folks. After a couple of days of troubleshooting, I discovered the solution to my problem. Apparently my WiFi password was too long, (42 characters). After reducing it to 32, my Maytronics robot was suddenly able to talk to my network. Yes, I know 42 characters is an unusually long password, but in my defense, my other 30 or so wireless clients had no issues with it. If this limitation is documented in the manual, I couldn't find it. The app was no help either. So after a very rocky start, my robot has been performing exceptionally well for the last 2 years. Only maintenance has been the replacement of the climbing rings once a year. I'm almost due for new screens soon, but not quite there yet. Minor niggles would be the cord - After a 2.5hr run I have a twist or two that need tending. I also still have to brush my top step occasionally. Not big problems, but worth mentioning. All in all, I'm very pleased with my purchase and would have given it 5 stars without the WiFi hassle. Consider my 4 stars a solid 4.5. ******************************************* ORGINAL REVIEW: My unit will not connect to WIFI. I tried different access points and tried Android and Apple apps to try and finish the setup, but it will not connect. I called customer service and was on hold for 45 minutes. When the nice lady answered the phone and I explained what the problem was, she asked for my serial number and email address and said that she would send me a "troubleshooting tips" email so we can determine the problem. I was then put back on hold and several minutes later, I was disconnected. I called back and waited an hour on hold before giving up. (I was probably too angry at that point to carry on productive conversation anyway.) My only recourse now is to wait and see if they answer my tech support request that I submitted through their website, take a vacation day and call back again or try and set up an exchange through Amazon. The cleaner itself works great, but if you can't use the app, then you can't control the robot AT ALL. I honestly don't care about being able to steer the thing or anything fancy like that, I just want the robot to run on a schedule. Problem is, is that ALL the features are ONLY available through the app, which includes a simple cleaning schedule. There are no controls on the power supply whatsoever - just an on/off button, that's it. I don't want to come off as petty about my expectations of this product, but comon! - $1500 pool robots should not be having these issues. And locking every single control feature to an app without a backup method is just plain dumb. I should at least be able to have some fundamental control through bluetooth, (which connects fine, BTW), but apparently this robot needs to contact the mothership through WIFI before you can do anything with it. As for the handy "troubleshooting tips" email, it never arrived. I'm very disappointed with Maytronics.

Purchased in May 2024. On arrival the box was substantially damaged, poor interior packaging, certainly not original from factory and I was doubtful that the machine would operate properly so I elected to return it back to the pool supply store. The store would not accept a return without an outrageous restocking fee and shipping charge. I elected to try the cleaner and was relieved that it worked flawlessly with excellent results. I then downloaded the app and unfortunately it failed to connect with the app. I contacted the support team and tried numerous troubleshooting strategies. Each time the same communication error between the robot and app appeared, suggesting I reconnect the blue cable. I gave up and for a year accepted a manual machine without the app control. Mid June 2025 the Robot failed to operate. I tried contact with Maytronics via phone, web and email, all which were built in such a way as to thwart a customer from talking to support. Really suspect. It’s been a reasonable amount of time and still have not been contacted by the company. I took the robot apart to check the cable and found the water proof plastic cap holding the power cable to the impeller unit loose with water intrusion and extensive corrosion on the internally electrical fittings, thus the failure. Was this a refurbished unit? Continuity test revealed two open connections and paper thin metal on the connectors attached to the blue cord. New cord out of pocket $290.00. Buyer beware, the seller hides behind shipping and restocking fees, the company behind a web page and non existent support on the internet. No warranty as advertised.

I ordered this for our inground pool and it is perfect! We nick named him Wall-E and he does a good job at getting leaves and small rocks. He scrubs the pool walls but has trouble with steps (understandable) He is pricey but worth it. I do notice any water leakage but if the pool is really bad like the first clean of the season you may have some leaves come back out. he does not run on battery as he is plugged in and the cord hardly ever tangles because there is a thing on it to prevent that. It was easy to assemble and had a quick start. We take him out and do not leave him in the pool full time as other reviews indicated issues with this. We did get a stand for him to make it easier to move as it is heavy and we got a cover to protect it. It is an investment but worth it. It has an app that you can use to change different cleaning modes and choose between cleaning floor and walls and just floor.

What it does well: It can drive in random straight lines sucking up fine dirt (with appropriate filters) and most large debris. The included dirt filter bags work well for getting sand and dirt out of the pool. What it doesn't do well (and things I paid for that don't work): I have a freeform pool with no straight walls. The robot will only climb the walls in a couple of places around my entire pool. I think the robot's width and the curvature of the walls make it impossible to keep the tracks against the wall well enough to climb them. I didn't mind because it seems more like a gimmick to me. I've never had a problem with the cleanliness of my pool walls. The app could be better. Ah, who am I kidding? The app is terrible. Scheduling is nearly impossible. Manually controlling it is a joke—it only turns in 90-degree increments, and there is at least a 3-5-second delay before the robot reacts to your input. I could go on about the app, but take my word: You'll never use the app except to turn the robot on or off and maybe to schedule something - but don't have the kids around when you are trying to do this. The way the baskets are engineered, leaves will get stuck in the pouch that allows entry into the basket. When this happens, debris will wash back into your pool. If you don't need to vacuum leaves out of your pool, then you are in the clear, but if you have leaves, this robot's basket design has major shortcomings. The plastic sides that wrap around the wheel axles are rubbing and breaking away. Those sides scrape against the pool sides and will wear down and break off over time. I have since bought a robotic vacuum that doesn't have sides covering the tracks, and THIS is what everyone needs to be looking for. The design of this robot is like designing something that is forced to fail in a few years, so you have to buy another one. Customer service: H-O-R-R-I-B-L-E My Dolphin decided it didn't want to run anymore, so I sent my Dolphin in under a warranty request (I've only had it two years) and have not received any communication other than telling me they received my robot (automated email). So, I logged in to their website to see my warranty request as "closed." So I opened up another request referencing this request asking for the status of the claim, and now they have closed that request, but still no communication. So, why don't I call them? Great idea. Let me look at their email about how outstanding their customer service is and how they will baby my sick robot ... there is no number. No email or phone number is listed. They signed off on the email as "Happy to provide an exceptional experience, Maytronics Customer Care Team," and that is it - no phone number or email address. Hey, Maytronics ... you failed. I did look up a number (it was not easy to find), and the woman who would have rather been doing anything else than talking to me looked up my claim and gave me a standard answer of 2-3 weeks on the time to repair. Um, thanks. So you really have no idea then. I don't do the conversation justice, it really was exceptional. Before I sent it in, I had this brilliant idea of taking it to a local Maytronics dealer and having them fix it. This would save the shipping cost. I called the local dealer, and they said it would be $75 to have them look at it. Fine, I'll pay that. But after a brief hold, they returned and said they wouldn't touch it unless I bought it from their store. Are you kidding me? I guess this is part of their wonderful service. Verdict: If you don't mind a HEAVY robotic vac (50 lbs with water) that is built to last 2-3 years, doesn't reliably climb walls, has no usable app, or drops debris back into the pool anytime it vacuums up leaves, then hey, waste your money. There are cheaper robots with fewer features that do the job (vacuuming the floor of your pool) just as well. I bought an Aiper Scuba S1 as a backup until (or if) I get my vacuum back. It costs a third of the Dolphin Nautilus CC Supreme, weighs about a third as much (maybe 20 lbs wet, 15 lbs dry), cleans about half my walls, and does NOT dump debris back into the pool. The Dolphin might become the Aiper's backup! Anyway, this isn't an advertisement for the Aiper. My point is, why pay for all these extra things you end up not using, or that won't work correctly, from a company that doesn't give a flip about providing "an exceptional experience" when you have a warranty claim? UPDATE: Finally got the Dolphin back. They just told me when it would be delivered and that it required a signature. That time frame did not work for my schedule, so I had to spend $5.50 to have the delivery time shifted three hours. In the end, FedEx left it without a signature, sitting on its side. I have not plugged it in yet, but I shipped it in the original box and got it returned in a different box. It's no big deal, though I liked having the original box. There was no explanation for what was wrong or what they "fixed." The corner plastic over the wheel axles was not fixed, even though that is partly why I sent it in. There was no explanation as to why they were not replaced. Would you put this back into your pool (see picture)? I'm still using the Aiper as it is much lighter, cordless, and works almost as well at a third of the price. I think I will try to trim up the Dolphin and sell it so that I may recoup some of the enormous wasted money I spent on the half-baked features. Lesson learned. ANOTHER update (4/24/2025): So, I definitely have strong opinions about the Aiper and the Dolphin that I wanted to share. The Aiper is very good at picking up leaves, while the Dolphin is rather horrible at it. This is due to the way the leaves get pulled into the baskets. The Dolphin uses a narrow pouch that often times catches the leaves and clogs the opening to the basket while the Aiper uses a solid plastic latch that opens when it runs and closes when it turns off. So I generally start off with using the Aiper to clear out the leaves from the pool. After a couple runs of the Aiper, I have the Dolphin come in with the dirt filter mesh and the weight of the dolphin along with the three brushes on the bottom can clean the floor of fine dirt very well. Neither cleans the walls, neither cleans the waterline of my pool which is a freeform with no straight sides. If you have straight sides, it may work for you, but I can't speak to that. I leave the Dolphin in the pool 24/7, unless the Aiper is running. Cleaning the Dolphin is a pain because I have to pull it up to the water surface using the cord - not good for the longevity of the machine. The Aiper comes with a hook that attaches to the end of a standard pool pole and you just lift it out, pretty simple. All in all when it comes to pool cleaners, look for something with a basket with a plastic latch that snaps shut, and also has fine mesh dirt filters for when you need to filter out the dirt on the pool floor. And of course, one that does not have plastic around the wheel axils to rub on the sides of the pool. The remote-control phone app for the Dolphin is still junk. When I need to use the Dolphin, I just push the button on the control box. Scheduling was nice back when I didn't have leaves in the pool, but now that I am having leaves, the weak points of the Dolphin became more obvious, as I have spoken about already. Nothing does the stairs well. You will always need to brush them before running the cleaners. I don't believe anybody that says their cleaner does their stairs well.

After reading quite a few negative reviews, I had few major concerns when I purchased this expensive item. People reported that eero extenders could be a problem, robot stuck in the middle of the cycle etc. However, in my case I had no problem connecting to an eero router even without turning off 5GHz (eero offers such an option via application) It quickly connected and started cleaning the pool. It got stuck at 23% the first time, but was able to complete the cycle the next time. To be honest, after opening the pool it's not in the best shape, so I did anticipate it will take multiple rounds to clean it up. I did anticipate that after the first pass it would be 80-90% clean, but in reality it's about 60%, so I assume it will take 3-4 rounds to clean it up completely. Still much better than doing it manually. The length of the cable is more than adequate. I was surprised to learn that the control block is not waterproof, but water-resistant, so it should not be exposed to water (i.e. rain will be a problem) Well, it's a minor issue to me. Also, wall climbing seems to be exaggerated. So far, I have not witnessed waterline scrubbing (still learning) It does climb the walls, but stops short below the surface without reaching the waterline. Maybe some other routine does that - still learning. I did not see the software issues one of the reviewers described (cut the schedule line), though the need for the cloud connection is concerning (cloud connection did not stop the robot from moving though) Lack of notification on the phone when the robot is stuck or cycle complete is also slightly annoying. Simple thing to do and would save a lot of hassle. Cleaning the filters is a super easy process. Bottom line - so far so good. I'll see how it works in a long run, but it's definitely a huge time and energy saver compared to the manual cleaning. Update 3 days later. The pool is not sparkly clean after 5th cycle (1 is thorough, others are regular as I do not see much difference to be honest) Those disconnects from "cloud" are getting annoying. Usually, the connection restores rather quickly, but I had once to disconnect power to restore the connection. It seems wifi functionality of Dolphin can be improved. Also, I cannot get the robot to get to the waterline. The video shows nice waterline scrubbing, but in my case it stops on the first angle between floor and vertical wall rather than climbing to the waterline. Furthermore, I am totally puzzled by the sentence in the manual that the handle must be adjusted diagonally. What does it mean? How? Instructions are not provided. The handle can be adjusted, no doubt, but what is the right position? And what's the difference does it make? I guess I'll have to experiment or call Dolphin to figure out.

Πολύ καλο

De momento funciona perfectamente. Tiene fuerza tremenda de aspiración y precisión sin dejarse nada que limpiar de mi piscina. La aplicación va estupendamente. Gracias

C’est un très bon choix de qualité supérieure
