Dolphin Nautilus CC Pro Wi-Fi Automatic Robotic Pool Vacuum Cleaner, Wall Climbing, Waterline Scrubber Brush, Ideal for In-Ground Pools up to 50 FT in Length

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.

Yet another update: The second power supply has now failed. The first symptoms of the failure were that it had apparently "lost" its configuration and had to be re-adopted/re-connected to my WiFi network, the same as if it were a brand new unit. It lasted for 1 cleaning. The next time I tried to use it, it was in the same state only that time, despite attempting to re-connect it a half dozen or more times, it would not successfully connect to my Wifi network. Mind you, the power supply itself when in use sits less that 30 feet away, line of sight, from an outdoor Ubiquiti Unifi Pro access point that's also supporting multiple WiFi cameras that are several hundred feet away and are all working fine, so it's not a WiFi signal problem. Maytronics continues to pretend that they're not aware of chronic wide-spread problems with these power supplies. Revising this review again. I now truly regret this purchase and wish I have never seen this thing. Here's the latest: It's about a year old at this point, still in warranty. So far we've had one power supply go bad. It took a long time to get a replacement because they were out of stock. I assume because so many of them fail. I just dropped off the whole system at UPS to ship for more warranty work. Now we get nothing but error messages saying that the controller can't communicate with the robot. After talking with support they decided I needed to send the whole thing in (at my considerable expense) to the repair center in Georgia, still under warranty. Here's the telling part: As soon as I walked into the UPS store with that huge box, the counter person said, "That's a pool robot, isn't it?". Says I, "Yes, how did you know?" Counter person, "Because we get a LOT of those." All Maytronics? "Yep". Don't get me wrong, when it works it works really well, but with two big problems still under warranty and the initial cost, I tell you that dumb, simple pressure side Polaris we got with the pool is looking hard to beat. Further update: Checking the UPS tracking told me it arrived at their facility 7 days ago, yet I've heard nothing so I contacted them for a status. Here is what I was told: "• I see that your unit was delivered on 9/25/24. The unit has not been received in the system yet. Receiving is one week behind due to a surge of units coming in needing repairs. The turnaround time is 2-3 weeks after being received in the system. We appreciate your patience during this time. Once repairs are completed the unit is shipped back to you and a tracking email is sent. They also send an email letting you know when the unit is received in the system." So their receiving is at least a week behind, and service is at least 2-3 weeks behind. Why? Because of the number of units that have had problems severe enough to require them to be sent in for service. To quote a friend of mine: " It's h*ll when it's well, but it's sick ALL the time!" Original revision: After having lived with it for about a year now, I'm revising my review. Performance-wise, it works very well and I'm happy with the job it does. HOWEVER: Slightly less than 12 months in, the power supply has completely failed and will not power up at all. Contacting customer support, they agreed to ship me a new power supply with almost no questions asked. In fact it was SO easy that now I'm thinking that Maytronics must already be aware that their power supplies are plagued with frequent failures, especially considering some verbiage I found on their web site about the process for dealing with power supply problems. Also, although the robot itself can be operated without an internet connection or with their app on a smart phone, most of the features are not available without one or both of these. For instance, you can't set up a cleaning schedule, you can't alter the type or the duration of the cleaning cycle, you can't manually "drive" the robot around, and you can't get feedback about the condition of the filters. Their default mode of operation requires an active internet and wifi connection as well as a connection to the Maytronics servers. It's possible to switch the robot to communicate with the phone app over bluetooth, but that option is somewhat hidden in the menus and even in that mode, it's not clear whether or not the system still communicates back to Maytronics. (I could find that out via a Wireshark trace but so far, I haven't cared enough to do that.) I'm still happy with how well it cleans, but the "other stuff" above is now more of a concern to me personally. Original review: We have a large-ish 40,000+ gallon pool Likes: Does a thorough job. Filters relatively easy to clean. Being attached to a cable as opposed to wireless may seem like a con, but it means the suction motors can be stronger and more powerful than they could be if it were 100% wireless which means it does a good job. Climbs/cleans walls and cleans the waterline very well. Dislikes: The Android app used to control it does not have an 'exit' function. You can dismiss the app by using the 'home' button on your phone but the app will continue to run in the background which means it's still consuming memory and battery (and possibly sending who knows what information back to the Maytronics servers). To completely exit the app and stop it, one has to use the phones "force stop" function. (This is probably true of all Dolphin robot cleaners). When I reported this behavior to tech support, they seemed unconcerned and not willing to fix it so now that I know, I always just force stop the app when I'm done.

I love the dolphin cc pro. I was a bit hesitant given the price as I already had a polaris 3 wheeler that did a good job with leaves but floated around on the surface alot. The cc pro never floats around, it is always on the pool floor cleaning. I also had a perpetual problem of a general layer of dirt from leaf debris etc in my pool, you know it when you sweep and see it. Could never get it all out. Dolphin cc pro got out ALL of the dirt and ither nasties as well as leaves. It is super easy to use and the app works well also. I highly suggest you buy the ultra fine filters that did not come with this unit. They are around $100 (I bought a generic brand) but those filters really keep the collected dirt in the unit. The one thing that is weird is that it is a bit random on its floor pattern. It gets up everything and cleans the waterline, but it only runs for 2 hrs and I am not sure it is getting all of the waterline each time. You can run it with back to back sessions but I don't think it remembers where it went before. Not a huge deal but one thing. Lastly, my controller stopped working in the first week. Called the company and within a few minutes, they were shipping me a new one. So great customer service.

Funciona bien, aunque si quieres que la deje perfecta necesita ponerse 2/3 veces. Sube paredes y limpia línea de flotación

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.

This is one of the best products I’ve ever bought. It saves me so much time and does a wonderful job cleaning the walls of my pool. Something that I wouldn’t be able to do that often .Now with scheduling app I can run it three or four times a day a week whatever don’t have to worry about when it’s clean for people coming over. My pool is always clean. Love this highly recommend it go . get it !

I purchased this unit and within a few months of use I got a red warning light. After going through the trouble shooting I determined it was the power supply. I called the company after my email was ignored. I was told I would need to ship the entire unit back to Ontario for inspection. I advised this was ridiculous when the problem was with the small power supply not the robot. They said I need to send it all back. When I advised it was pool season and I did not want to do this they gave me the names of two local Vancouver sellers where I could drop it off. After calling each of them I was advised that unless I had bought it from them they would not help me. The cost to ship the entire unit is $150+ which is NOT paid by the company. I was told it would be 2-3 weeks to get the unit back. This is when a warranty is not really a warranty. They make it so difficult to get a nearly new unit serviced that they hope you buy a new power source ($450+) to not lose access to your cleaner for a month. This is my second unit. The first lasted 5 years but required a replacement power unit at $350. Bottom line, Maytronics makes poorly built units. The warranty is an illusion as I found out. I will not be buying another unit. Avoid this purchase.

I have owned this pool robot since 2023. When we bought this pool robot, we pictured a future of seamless cleaning and low maintenance upkeep. In practice, there is a fair amount of maintenance required to keep the pool cleaner working well. It requires a constant power source and monitoring because it may get stuck or pause its cleaning cycle due to various issues. One common issue you will face if you have lots of tree leaves / debris falling into your pool is that it will stop cleaning mid cycle due to issues with being overloaded. If the filters collect too many leaves or debris it may not be able to get up along the water line and clean the top of your pool effectively. You will really have to carefully read the owners manual with this pool cleaner, as there are various settings, such as the position of the handle bars that can impact the performance of the pool robot and how it moves along the waterline. This was a surprise to me that it took me a year to discover. I think if this pool robot had better warranty and after sales care from the manufacturer, it would be a lot more successful. We are going into our third season with this pool robot this year and I don't expect it to last much longer. Be careful when considering whether the cost is worth the investment here, because it may not be if you have a lot of debris to tackle with this robot. I would recommend buying it on sale if your pool is relatively low maintenance, but otherwise you may want to look at other products that have a better long term track record.
