Dolphin Automatic Robotic Pool Vacuum Cleaner, Wall Climbing Scrubber Brush, Smart Navigation, Ideal for In-Ground Pools up to 50 FT in Length - Nautilus CC Plus

The Dolphin was delivered today (ahead of schedule), and after reading the Quick Start directions, I put it to work immediately. There's almost nothing to it. Connect the waterproof cord to the console, drop the unit into the water, plug the console cord into the wall socket, press the power button. We have a rectangular fiberglass pool with salt water. It has a large sitting platform which is about 2 feet deep. The platform then drops off into the deeper (lap swimming) end of the pool. The pool is 6 feet at the deepest end. I dropped the Dolphin into the deep end then hit the start button. This unit is advertised. It was definitely vacuuming up the debris. It picks up the pebbles, and it actually crawls up the pool wall to the point where at least a third of it breaches the surface, then drops back in. However, I have seen it crawl up the 4 foot wall of the platform, at which time it cleans the platform (briefly), until it blindly rolls off the platform edge, descending into the deeper water. After two hours, the bottom was probably 98% clean. There were a couple of 90 degree corners that it just couldn't quite pick up, so I'm currently running it for another hour. Perhaps I will stir up those two corners next time to give it an assist. Lastly, our pool has two steps to the deeper water. The unit appears unable to crawl up the stairs. Five starts because it is convenient, simple, and effective. Update: In order to get the last 2-3% of dirt left over in the corners and at the base of the walls, we first brush the debris toward the middle of the pool floor. Then, we run this unit for an hour and the pool looks great! ~ We use this unit about once per week and always after the lawn is mowed. ~ I set it on a small 2x4 block to keep pressure off of the brush up front. I also sometimes set it on it's side when it's not in use. Nothing to warp when it's on its side. ~ We gently spray out the debris bucket with the garden hose. The filters on the side seem delicate/fine (which I'm guessing is why the fine dirt doesn't appear to pass through the system). ~ In order to retrieve it you use the power cord to pull it in. It's very light when it's in the water, but when it gets within reach, grab the unit itself. This prevents undue stress on the power cord when it's full of water. Bottom line: This thing doesn't care how blazing hot or ice cold it is outside or how long its work shift is, it gets the job done so you don't have to. Update (1 year later): The Dolphin still does its thing. When not in use we keep the unit in a pool locker in the back yard, except for the console. We keep the console inside the house to keep the electronics better protected. Prior to using the Dolphin, we brush the base of the walls. This makes it easier for the Dolphin to get this more easily. Sometimes I push the button for a second cycle, but it usually does a fantastic job with a single cycle. I've left it in our salt water pool for a couple of nights in a row before. It doesn't seem to mind and it doesn't let go of the debris during that time. I use it year round, usually at least once per week in the warm months, perhaps a little less in the winter. 1 year later, it still does the job very well. I'd never go back to doing this myself. The pool needs enough attention as it is (water testing, water level, filter cleanings, etc.). I do wish that it had a remote control option, something that I could hold so that I could direct it to "mow" the platform clean before plunging back into the deep water. Great purchase! I'd give it 5 stars again. Update (Beginning of 3rd year of use) Nothing has changed from above. I still store the dolphin (upright of the tracks) in the locker outside year round, the console is still stored inside the house. Prior to use I still sweep the base of the walls. This makes it easier for the unit to get the dirt and debris. The pool is clean in about 90 minutes, though I usually run it longer for an extra clean pool. I guess it takes about 10 minutes or so to sweep then set up, but it would take the same time to set up the manual system too. Same with break down, 10 mins or so either way. But of course with the Dolphin I'm off doing something else while it's doing its thing. No parts have deteriorated since it was brand new even in a salt water pool. It's as good as new still. I see newer Dolphin units with a built in swivel in the cord. After many hours in my pool the cord does develop the beginning of a kink (twist) in the cord but the cord is so long that this has never come close to hindering its effectiveness. After use, I lay out the cord along the lawn then roll it back up losing the minor twist for next use. I also see units with optional remote controls. For the large platform in my pool I simply manually (mow) it clean, that is I run it one length, turn it off, set it into position for the next run Turn it on, etc. Yes, I'm in ankle deep water with it as it's running but the platform gets clean in short order. I think a remote control for this short work would take longer. I need it to make several U-turns on the platform, slightly overlapping the previous run. I think using a remote would take much longer. Aside from that we're rarely in the water with the unit. Excellent pool accessory! Simple and convenient. Glad we made the purchase. It certainly is better than cleaning the bottom when it's 100 degrees or freezing outside.

I purchased a suction cleaner for $200 and it worked well but since I only have 1 skimmer I would lose the function of the skimmer and I still had to deal with the hose and cleaning out the skimmer and backwashing etc. When the suction vacuum went bad last year, I purchased a Polaris 360 side wall pressure cleaner about a month ago. I was excited since I have 3 output ports so I could use the skimmer and the Polaris vacuum at the same time!! The Polaris 360 would go in circles, never leave the deep end. I also came home and found it floating in the pool!! I called Polaris and they could not help so back to Amazon it went. Next I researched the robotic pool cleaners and found the Dolphin Nautilus CC Plus. It arrived, I read the easy setup paper that came with the cleaner, I cut the packing plastic off the front and rear rollers, checked the inside filters that were already installed. Put the vacuum in the water, hooked up the blue power cable to the power supply timer. Plugged the timer into the GFI outlet on my house. Pressed the power button on the timer/power supply and away the vacuum went. My pool is a oval in ground vinyl pool 34 feet x 18 feet its 8-1/2 feet deep and 4 ft in the low end. This vacuum went up the walls, went around the edge , even over the skimmer, down into the deep end over the bottom drain and into the low end. It tried to go up the steps but couldn't do it. In approx 2-3 hrs the pool was crystal clear!! I opened the top of the cleaner, removed the 4 filters that came straight out easy, then I un-clipped the filters and cleaned then with my hose. Finished in 2 minutes and could not believe how much gunk this vacuum found. Reinserted the now clean filters and I'm ready for the next pool cleaning. OMG, this is an incredible machine! I put my manual vac and hose back into the garage. No more vacuuming for me! I will let the Dolphin Nautilus do it!! This vacuum is like having another filter roaming my pool. I bet I will not have to back wash very much anymore. Will update by the end of the summer. END OF 1st SUMMER UPDATE: WOW what a great summer with this easy clean pool cleaner. I wanted to give a tip, I could find anything that tells me how to winterize so it works perfectly next summer. So I emailed the MFG and they told me exactly what to do. They said keep the unit in an area that does not go below freezing and turn upside down and keep the weight of the machine off the rollers. Did exactly that and put the unit in my basement. So we will see next year! START OF SUMMER 2021 (3rd year) Vacuum Robot is still working perfectly. Found a small hole in one of the clear filters. No problem ordered a new set of filters on Amazon today and I still have another set of the paper filters that came with the robot that I am using. The beauty of this robot is you do not have to backwash you filter as much because this vacuum collects all the large and small dirt in the pool. Best Vacuum ever! UPDATE SUMMER 2023 Opened the pool in May and had tears in the cover, so I did have more dirt on the liner than usual. No problem Robot cleaned everything perfectly! Still working since 2018 when I purchased this. I keep it in our finished basement during the winter and it has never failed me. So happy with this purchase!

Where do I begin? I bought this from Amazon back in 2023. It worked perfectly until it stopped climbing the walls of the pool. Before I sent it out to Maytronic's authorized repaid center, under warranty to fix, I bought a back up. That was on March 23, 2025. 11 months after the first purchase. Upon receiving the new one, I sent the first one out for repair. It took 5 weeks to get it back! Has I not bought the second one as a "backup" my pool here in the Las Vegas summer heat would have been infested with algae! It took over 9 times to get the product to connect to the same wifi (2.4mhz) as the first one. Which was very frustrating. I placed it in the pool, and it worked fine an "climbed the pool walls" to do it's job as advertised. The first one was returned from repair and I noticed it looked the same as when I sent it. The guide wheels looked "used" as when I sent it. I casually dismissed the notion thinking it was "repaired" to its original working condition. Fast forward to September 18th. The back up (newest Dolphin) just stopped working. After 5 back and forth emails and phone calls, Maytronic finally agrees to issue a warrant RMA for repair. So, shipping cost for a second Maytronic dolphin was one me. Now I was out an extra $123.89 for TWO failed Doplhins plus the cost of over $1,845.00 for buying them. The back up only worked for less than 4 months in the pool! I place the original (repaired) Dolphin in the pool and the wifi hooked up immediately! BUT it would NOT climb the walls which was why it was sent in for repair! Unbelievable! Needless to say, it gets worse. The back up Dolphin gets sent again the their authorized facility and after the repair, and numerous calls to Maytronic's 3rd party call center in the Philippines, agrees to send a "prepaid" return label, the RMA and ship directly to Duluth Headquarters for repair. Meanwhile I have NO Dolphin in my pool and the algae grows. My back up plan failed miserably when I trusted their product! Now fast forward to October. I was promised another "prepaid label" to fix the wall climbing problem that wasn't fixed in the second repair!!! During this process (5 weeks now) Maytronics sends me an email.

Customer Care Team Turns out that this items is being sent to Duluth by A DIFFERENT customer not my return replacement! Unreal! Si, now I have a missing Dolphin, and email after the first warranty RMA was issued, asking my to prove the purchase receipt. Thankfully, Amazon order history was able to show "proof of purchase". So ask yourself, how did they loose the original receipt and approve a warranty (RMA issued) ? Just to recap as of today the Dolphin sent in TWICE for repair so it can clean the walls of my pool is still not working and I am waiting for the RMA< Prepaid Label! The missing Dolphin sent to Maytronics Duluth location is still missing!!! 3 unanswered emails with notice of purchase sent, I have heard ZERO from this company! Would I recommend this product? Sure if you buy 3 for continuous back ups you might be ok. Will update this saga as in develops. UN pleased customer for sure! $2,000 later and still NO working product in my pool! Not to mention the added $386.00 of additional algae liquids I had to buy to keep the pool from turning swamp green.

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.

Background: I currently have a large 27,000 gallon in-ground, vinyl liner "True L" shaped pool with a large 3.5' shallow end, 8' deep end, and 6-inch corners (these are fairly sharp corners). I have only used the standard vacuum type that comes standard with pools so far - a hose that attaches to the pool filter via suction and then the standard stick and vacuum end, I have not purchased or used an aftermarket pool vacuum or automatic pool vacuum in the past. I purchased a "Dolphin Nautilus CC Plus Automatic Robotic Pool Cleaner with Easy to Clean Large Top Load Filter Cartridges and Tangle-Free Swivel Cord, Ideal for In-ground Swimming Pools up to 50 Feet" in May 2020 on Amazon for $779. I purchased it based on the overwhelming number of positive reviews, its relative price-to-value, and the ability for me to have it serviced in-town, if needed. Out of the Box: Just a few parts - the vacuum unit and chord, power supply unit, and a set of extra fine filters and clips in a reusable bag. I plugged it in...nothing. Tried another outlet...nothing. Finally after troubleshooting everything I called Maytronics directly. They indicated this was not common, but did happen on occasion right out of the box. With a pretty easy 10-15 minutes on the phone, the serial number from the unit and my address, they had a new power supply shipped to me which arrived the following week (took about 4 business days). This one worked fine so I plugged it in and the vacuum started right up. Using the Vacuum: My pool is large (see size above) and was not covered for the winter as the patio had not been done yet in the prior season. As a result, it was pretty bad - algae covered surfaces, fine dust/dirt everywhere, small rocks from the patio underlay that had kicked into the pool over the winter, leaves, and just plain goop from decayed leaves and whatnot. The vacuum was unable to scrub the algae effectively after several passes with the exception of the foam part of the wheels/treads, so I had to use my manual brush to loosen the algae up. This caused the fine particles to go into solution in the water, which greatly clouded up the pool. Over the next few days I ran the vacuum repeatedly, emptying and cleaning it out completely and thoroughly between each cycle - which was quite a bit of dirt and leaves each time and nice because I personally could not see the bottom and would not have been able to manually vacuum it. During this time the particulate slowly settled to the bottom, and finally I switched to the finer filters. This really got the job done, and now it is crystal clear. With no more leaves or large dirt items, I am running it every few days using the fine filters simply as maintenance. Overall Conclusions: I am pretty satisfied with this overall. It does effectively clean the pool without me having to do anything other than put it in the water and then clean the filters (and apparently scrub hard to get algae, which should be rare). Importantly, it does not use the pool's filter, so when it collects dirt and whatnot it is then fully removed from the pool without getting cycled back through or clogging up the pool filter requiring constant back washing. I think this is a very important aspect of a good automatic pool cleaner. My only comment from a functionality perspective is the inability to control the vacuum manually. While this is not 100% necessary, I have noticed that the dirt collects in specific areas, and due to the size of my pool I have to run the vacuum through its full cycle once or twice to catch all those areas. With that being said, comparing the price for similarly-rated models the cost for that feature was so much greater I chose not to go that direction. I rated it a 4/5 Overall based on the bad power supply out of the box, need to run a few passes sometimes, its inability to be controlled manually, and fact that I have not owned it long enough to comment on (or rate) reliability. However, it is definitely a product I would recommend based on my experience so far. Hope this helps!

18x36 inground pool I received my Dolphin Nautilus CC Plus Robotic Pool Vacuum Cleaner a few days ago and finally got time to set it up and test it out. First off let me say that I've had a couple "automatic" pool vacuums in the past and hated them both. All they would do is get stuck in a corner and I'd end up cleaning the pool myself. But, with my wife's insistence and having read many reviews here I decided to give it a go. Starting with packing, no complaints here, it was well package and had no shipping damage and unboxing was easy. Setup and instructions: no complaints here either. Setup was a snap, plug the Dolphin Nautilus CC Plus Robotic Pool Vacuum Cleaner into the control box, plug the control box into the outlet and put the Robot into the pool. Whoops, missed a step, uncoil and untangle the long cord which is also easy. Ok, so now that it's in the pool it's time to turn it on. I press the power button and rush over to the pool with full expectations of being disappointed. The Robot moved forward about 3 feet and stopped! Here we go I thought, another so called robot device I've wasted my money on. But then it started moving again so I calmed myself down and decided to be patient and watch. I drove across the bottom of the deep end and started going op the slanted side but slipped back down. Then it backed up and tried again, this time it went up the slanted side to the straight up wall where is failed to climb and slid back down. "SIGH", On the third attempt it climbed all the way up and poked it's front out of the water, all the while the scrubber wheels were spinning and scrubbing. I watched it for at least 20 minutes and it went back and forth at different angles until it finally found the long ramp up to the shallow end where it climbed up and down more walls before heading back to the deep end. WOW, I'm impressed, but I wanted to reserve my final opinion until after it had a chance to clean the pool, so I gave it an hour and went back to check. WOW, my pool is clean! Except for the very corners where it can't quite get to but that's not a problem. After all it hasn't yet finished it's first cycle of cleaning. I'm impressed, I'm no longer a "pool robot skeptic" I'm now a "pool robot believer" Yes this is only the first cleaning cycle, yes it's the only experience I have with the Dolphin Nautilus CC Plus Robotic Pool Vacuum Cleaner but I'm still going to give it 5 stars. if anything notable changes I will update this review. Yes I would recommend the Dolphin Nautilus CC Plus Robotic Pool Vacuum Cleaner EDIT: 1 month Update: Just wanted to update on how the Dolphin Nautilus CC Plus Robotic Pool Vacuum Cleaner has been working so far. This morning was the first time I hade to vacuum the pool manually. There were 2 corners, 1 edge of the ramp to the dee[ end and the stairs that the robot missed.....that's it. All told I spent 10 minutes cleaning up where the robot missed and my pool is spotless! This is awesome and not a complaint! How I use it: As per the instructions, I turn it on and set it to 1 which is the 7-day operation. But, I only run it on Monday through Saturday, then I pull it out of the pool until the next Monday and start the process over. So far this works great and I only have to clean the robots filter once a week and it gets a day to dry out and rest, lol! Cons, I guess, but not really: I've had to untangle the cable once, It doesn't climb stairs and I still have to manually vacuum for about 10 minutes. Some will find it heavy when lift it out of the water but you don't need to do that every day. Pros, IT CLEANS THE POOL!!! The filter is great and cleans up in minutes. My only concern is that is becomes self aware, climbs out of the pool and attacks, LoL! I still highly recommend the Dolphin Nautilus CC Plus Robotic Pool Vacuum Cleaner!

I should have written this sooner. This thing is like the little engine that could! We went away for the week and came back to find our pool littered with grass at the bottom — the landscapers had come while we were gone. I honestly thought, there’s no way this little robot is going to handle all that! Well, it totally proved me wrong. It cleaned everything — even around those filter covers at the bottom of the pool where the grass had gotten stuck. I was shocked at how well it handled such a messy job. When I opened the debris compartment afterward, it was completely full of everything it had picked up, and the pool was spotless. I also bought the caddy, which makes storage super easy. After each use, I let the robot drain a bit, then set it on the plastic caddy — no water damage, no hassle. This little robot works hard, delivers amazing results, and is worth every penny. Highly recommend!

We have been using this pool vacuum for about a month now and absolutely love it. It was definitely more expensive than other vacuums (we had been using a midlevel Polaris before) but it keeps the pool cleaner and picks up the silt and other debris at the bottom of the pool better than past vacuums. It also cleans the sides as it can "walk" up the sides and even climb the stairs. Well worth the extra money. The only downside is that is has to be plugged in and is attached to a blue cord while in the water. I pull the vacuum out when it's done but it can be left in the water until the following day. The cycle takes about an hour, and the filters are super easy to clean. I would highly recommend this product if you are frustrated with being able to keep your pool cleaned.
