Nautilus CC Plus Robotic Pool Vacuum Cleaner with Wi-Fi Control — Included Universal Caddy for No-Hassle Storage — Ideal for Above/In-Ground Pools up to 50 FT in Length

We bought the Dolphin CC Plus WiFi Auto Robotic Cleaner which cleans a 40 ft length pool, ours is 29,000 ga, and it has been an amazing robot. We keep it scrupulously clean and use it several times a week if not more as trees surround our pool. Amazed that it climbs the pool wall surfaces and gets them clean! And dives down to the deep end effortlessly and cleans it too. We have had it two years and our pool is still open w/ this warm October. I set it up easily with the app and though we don’t use the app much it is reliable. Don’t use chemicals with the robot in the water and wash the easily accessible twin filters with each use and you’ll be stunned with how much gunk the robot picks up. Worth every penny. I read all the reviews before purchase and made my choice and we are very pleased. I made the decision to buy a little bigger robot than we needed but I felt it would pay off.

So. We put an in-ground pool in this summer, a big one, 20' by 40', slide, heater, diving board, 12 ft. deep end, 3 stairs, and a safety ledge which runs the length of both 40' sides. The pool had been up and running less than a week when it became obvious I would have to have a pool cleaner, referred to from here on as a "sucky" (blame the name on my mother). First, I looked locally for a sucky, and YIKES! the prices were outrageous, between $1500-2500 for what appeared to be an average sucky, although some of them had tails that whipped around, and others a remote control, and still others a programmable chip to tell sucky when and how long to run, and others which were wearing animal costumes?. I quickly realized that most of these suckys were going to require the installation of a separate pump to use them, which we had not had installed, and really didn't want to. I also realized for servicing, warranty or repair purposes, I better buy a brand that could be serviced locally, even if I didn't buy locally. I narrowed my selection down to either a Dolphin or a Polaris model, both of which could be serviced locally, then began searching online. After a lengthy search and then a comparison of my final 3 choices, I went with the Dolphin N+ model, for the following reasons which were stated in the item description: Size and weight of item was manageable for a single individual to move, put in, and remove from pool. Did not need additional pump. Able to clean safety ledge, steps, walls, floor, no problem, 4WD. Came assembled, ready to use, with extra filters. Filters were easy to remove and clean. Extra long cord should allow sucky to clean all parts of my large pool with ease. Replacement parts were readily available. Warranty was available. Next day delivery FREE available. Price was VERY competitive. Reviews were favorable. Sucky came with a computer chip which would map the layout of the pool, including ledges and steps, insuring sucky would do a thorough job, every time he was used. Sucky would take less than 2 hours to clean entire pool, THEN TURN HIMSELF OFF. I was sold. Ordered sucky, and he arrived the next day, JOY JOY JOY! I threw sucky into the pool and watched with great anticipation for sucky to do his thing. Sucky did nothing. Sucky was broken, arrived with a broken front mounting bracket for his front sucky wheels, causing the wheel to fall off when he tried to do his job. DEEP DESPAIR. I immediately felt sick, thinking $700, arrived broken and %#$&!?@ to get returned and replaced. Despondent, I contacted Amazon. To my amazement, they sent a return shipping label and a new sucky THE VERY NEXT DAY. AND SCHEDULED A PICK UP OF BROKEN SUCKY at my convienence. REALLY HARD TO BELIEVE I KNOW, BUT TRUE. Even better, the new sucky is amazing, and every thing said about him is indeed true, if I was to complain about him at all, it would be that his ledge and stair work leaves behind a bit of sand (salt water pool, sand filter), a very tiny bit, and I'd advise that you also purchase the storage stand, which isn't included but is sold separately, it gives a place to store the battery off the ground during use, a place to wrap the cord, and a little seat for sucky to rest on when he's not at work, and nice big wheels to move the whole thing around, similar to a moving dolly, but made especially for sucky. CONCLUSION: love purchase, easy to return and replace, does a great job, even on large pools, and reasonably priced. 2020 UPDATE: I get lots of questions from people wanting updates on Sucky every pool season, wanting to know if Sucky is still doing his job. I’m happy to report Sucky still works like he did back when he first moved in, and in 6 years, we’ve never had to replace a part, or had any problems. 2022 UPDATE: thought I should check in to tell you all we are still using sucky in our pool, and sucky still does a fantastic job keeping the pool sparkling clean, fully 6 year after we purchased him. We have had only one issue, and it’s a recent one, the button to turn him on isn’t working all the time, you have to repeatedly push it to get it to work sometimes. I feel like that’s to be expected, he wasn’t made to last forever. 6 years though, that’s an exceptional time frame for something like this, just a great choice of pool cleaner, yay me! 2024 Update: still working great, not a single issue. Now 8 years of use, and works just like it did when it was new. Just a superior product.

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.

Ive owned mine for about 5 years now, It did have an issue at one point about 4 years ago which was covered by the warranty and hasn't given any trouble since. I should have done this sooner but I came to review it now because I am, for the first time, looking for replacement parts such as the scrubber brush, guide wheels, electric cable and climbing rings. The robot does not float, and thus when it needs to be pulled out of the water it requires quite a bit of strength and will most likely cause you to get some water on yourself. the vacuum compartment (bag size if you will) is quite large, leaving enough space for one to not have to clean it very frequently, this ofcourse depends on your surrounding. My pool is covered with a bug proof pool cage so there is that. It does an amazing job at picking up debri from the ground, you are left with simply netting out anything that is Floating. My robot is usually left inside the water unless the pool is going to be used, we live in Florida with the sun hitting it head on most of the day, I consider this robot to be of very good quality, very much worth its money and would consider buying another in the future if the warranty being offered is fair.

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!

I previously had the Nautilus CC (not plus). It stopped working after about 3 years and I was so fed up with the tangling of the cord that I upgraded to the Nautilus CC Plus. I am very happy with this upgraded version (with the exception of it getting stuck on the steps). Pros: * Cleans a lot more areas such as the waterline and steps * The cord doesn't get tangled (so far) * Can run daily without intervention * No vacuum hose Cons: * It does consistently get stuck on the steps * It is heavier than its predecessor * The baskets are annoying to clean out (but also can be a plus see notes below) I do love the Nautilus CC Plus vacuum and I think it is well worth the investment. Since we upgraded to the "Plus" version our tiles have remained clean with little effort on our part. My husband said he could tell a big difference when brushing the pool, the steps have little dirt compared to previously. The cord! I can't say enough about the cord. The previous version did not have a swivel cord and after a year of use, it was similar to the old telephone cords that would get so tangled you had to try to dangle the phone to let it spin to untangle. Unfortunately, you can't dangle the cleaner to do the same, so no matter how much I tried the cord would just tangle back up in a day. With the "Plus" version it comes with a swivel cord and while you may see large circles of the cord in the pool it does not get tangled and can do its job. This earns major points in my book. My con's are not enough for me not to recommend this pool vacuum. The biggest issue is that it does get stuck on my steps about 80% of the time. It just manages to get at an angle that the brushes/wheels just spin and can't grab anything to make it move. Usually, it is so close to the surface that when it is stuck it is very noticeable because the water shooting from the top (which is designed to push it against the floor and walls) is like a waterfall sound. Due to it getting stuck often, I run it during the morning before I go to work so I can listen to it and redirect it when it happens. I mentioned the baskets were annoying to clean. This is compared to the previous version and it is a + and -. There are two thin baskets to clean. You have to take a part the basket in order to remove the debris which if that is all you want to do is a little annoying. However, if you want to fully clean the basket, hose it down, etc. the fact that it comes apart makes it much easier to run under a hose and remove all the debris. It may be heavier than the previous version but that may be why it works so much better. The fact that it climbs up the wall and rides the waterline, cleans the steps (even if it gets stuck), and has a swivel cord so it doesn't get tangled makes it a great product. I do wish I would have purchased the version that can be controlled by the app but at the time of purchase, it was $100 more. At the time I'm writing this review the app version is the same price I paid so I missed out on that. Next upgrade I will include the version controlled by the app for added ease of use.

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!

Not built as well as past Dolphins. My first Dolphin was a Godsend! I bought it when huge tree fell, taking out my pool equipment. It cleared the debris and kept my pool clear until I had all up and running again. Even with the heavy load, it lasted 8 years and was an awesome workhorse. When it finally played out, there was no question I would get another. This Dolpin Nautilus CC Plus was wonderful for 1 and a half seasons. One day it just did not power on. I am overly gentle with my equipment. I have a hook to lift from pool and always clean filters and unit after use. And I store inside cool and dry. I do not leave in pool, even tho they say it can be. Warranty was still in effect, so I shipped to repair as instructed. I sent in original box with proper packing support (which I use to store my Dolphin in winter). They returned my "fixed" unit in a flimsy box with out my winter storage box 😓 There was NO information what was wrong or what was done. I can tell there is a smaller gauge and shorten cord attached. It no longer reaches the end of my pool. I had purchased the extended cord to fit my longer pool. My "repaired" Dolphin does not clean as well. I rarely have much for it pick up yet it leaves some behind. It does not have the same suction, not able to climb as it did before. I am saddened that Maytronics seem to have downgraded their quality. Response from customer service was slow and unhelpful. They sent standard printed information on care not specific help. Easy enough to send in for repair but they did not return with my sturdy box or with ANY explanation on what was done. Attached an obviously lower grade cord. Customer service communication needs improvement!!
