Dolphin Nautilus CC Plus Robotic Pool [Vacuum] Cleaner with Wi-Fi – Pool Cleaning from Anywhere, Anytime - Ideal for In-Ground Swimming Pools up to 50 Feet – Easy to Clean Top Load Filters

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.

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.

I had the previous model with a simple non-wifi power supply. It was fantastic, lasted almost 9 years with no problems. Eventually the cord wore out so I replaced it with a mechanically identical version, except now it only comes with the wifi power supply. Despite the annoying app and connectivity issues, mechanically it worked fine.....for about 6 weeks. Then one day the power supply refused to turn on when I plugged it in. GFI was fine, voltage fine, no extension cord, not wet, followed all the instructions. Tried to troubleshoot via Maytronics website. It's dead. I have tried since 7/22 (it's now 8/7) to get ANY kind of help from Maytronics. I have spent many hours on hold on the phone, with "live" chat, and submitting help forms to get a call back since that day. I HAVE NOT ONCE TALKED TO A SINGLE CUSTOMER SUPPORT PERSON IN THE COMPANY!!!! It is absolutely IMPOSSIBLE to communicate with someone to get the issue resolved. I have gotten 3 emails back....each one only stated that the best way to get help was to use phone number or live chat. Neither one has ever led to me having ANY contact with the company despite wasting at least 6 hours total on hold, and that's NOT counting the time spent on "live" chat waiting for a response. It's a DISGRACE!!! You know you're gonna get screwed when all of the emails and even the website give the old "We're experiencing higher call volume, so expect a longer wait time" BS line. It's an intentional blowoff of the customer because they don't have enough service people. My next step is to try to get a refund from the seller or a charge back from my credit card company because Maytronics doesn't honor their warranty. I will NEVER buy a Maytronics product again, and I LOVED the old version of the product they made. I bought this product because I have two bad shoulders and vacuuming the bottom by hand is extraordinarily painful, not to mention time consuming. I didn't pay $800 to have over two weeks of the summer wasted by not being able to clean the pool properly, with no end in site. This is a garbage company.
