DolphinNautilus Pool Up Automatic Robotic Pool Vacuum Cleaner, Floor and Walls Scrubber Brush, Ideal for Above/In-Ground Pools Up to 26 FT in Length

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’ve owned my Dolphin Nautilus CC for 1.5 years now, and overall, I’m extremely satisfied. It does exactly what it promises—keeps my pool clean with minimal effort—and the customer support from the seller has been nothing short of excellent.Pros:• Cleans exceptionally well – Picks up dirt and debris efficiently every time.• User-friendly – Simple to operate and easy to maintain a cleaningroutine .• Outstanding customer service – Anytime I’ve had an issue, the company was quick to help. They offered to repair it with no hassle—just ship it in, and they return it promptly and fully functional. Best after-sale support I’ve ever experienced.Cons:• Cord tangling after about a year – The cable started to twist and tangle. I’ve laid it out in the sun to help straighten it, which works temporarily but never fully fixes it.• Replacement parts are pricey – If the a part goes bad, replacing it can be expensive but not crazy pricey.• Storage matters – I suspect leaving it out in the sun and in the pool all day may have contributed to the cord issue. I recommend purchasing the caddy for proper storage. it’s likely to extend its lifespan.Final Thoughts:Even with the cable issue, this pool cleaner earns a solid 5 stars from me. The product works great, and the company truly stands behind what they sell. If you take good care of it, it will take good care of your pool.

We received our cleaner on Sept 5, used it for 1-3 cycles per day, always in the evening so that the body wouldn’t be exposed to too much sunlight to keep it looking nice. We pulled it out of the water in the early am and kept it in the shade during the day. On Sept 14 unbeknownst to us, it failed to complete the cycle. The next morn (Friday) I started it again just to have it not complete the cycle again and when my husband came home from work, we did the troubleshooting that the manual recommended but could not contact Maytronics customer service as it was after hours. On Monday, Sept 18, I spoke to a rep at Maytronics and after assuring her that we HAD ALREADY done the troubleshooting, she looked at the history (I had set up an account via wifi so that I could operate the unit that we named “Flipper” remotely) and determined that the impeller motor had failed in some way. She informed me that I would have to box it up ( we had luckily saved the original box and packaging) and I would have to drop it off to FedEx to return it to Georgia for warranty repair. After evicting our old Pentair Prowler 930 from the box, I took it that very morning. I had been assured by the customer service rep that the turnaround would be very quick, approximately 10 business days and sometimes sooner. They received Flipper on Wed, Sept 20 at 10:53a according to tracking. On 9/22, I received an email from Maytronics asking me to fill out a survey for feedback stating that “Your (not my typo) recently sent your Nautilus CC Pro robot for a repair and it should be back in the pool by now”. SERIOUSLY?!!! We’ve contacted customer service (no small feat) a couple of times now and after being misdirected to the wrong service location, was told it could be expedited, they keep extending their estimate on turnaround and, as yet, they have no updates for when we will get our pool cleaner back. We called again yesterday (Oct 6) to check on progress, still no news except that they have a lot of customers and many repairs (there’s an endorsement!) and that it will (now) take 2-4 weeks!!! We even mentioned to the rep. that the service department has now had it longer that we did ourselves!!I purchased this based on reviews, our own experience with a Maytronics product thru Pentair and because after nearly 4 seasons, our Prowler had stopped working. We close our pool on 10/23 and I certainly hope we will have our cleaner back in time to not only get the pool clean but to verify that it truly has been repaired. Oct 6 was our deadline to return it and perhaps if I had known before I had sent it off to Maytronics to be repaired, that it would take this long, I would have eaten the return costs and sent it back to the seller instead and ordered something else!!. I would have at least had a pool cleaner working in my pool a lot sooner than now! Hey Maytronics!!!…I’ll be happy to update my review in the future because for the first 9 days, it operated wonderfully but for what I purchased Flipper for, so far, it has cost $129.43 w/tx per day to operate and no one would consider that a very good deal!!!***update****Shortly after leaving the above review, I was emailed by Tamara B. at Maytronics that my robot had been evaluated and would be repaired the next day (10/10) then returned to us within 24-48 hours. We had it back in the pool later in the week and it worked well until the day we closed our pool. Hopefully, we’ll get many years of use from our Flipper!!! It’s too bad that it took a bad review to get action on our case but thank you Tamara, for your info and action!!
