Dolphin Nautilus CC Plus Wi-Fi Automatic Robotic Pool Vacuum Cleaner, Always Cleaning, Never Charging, Ideal for In-Ground Pools up to 50 FT in Length

We bought a house with a 16' x 36' pool in 2013. This was a new experience for us, and we tried to become pool people... water analysis, filter operation, chemical addition, etc. The thing I hated the most was the chore of pulling out the big coil of hose and setting up the vacuum head on the 16' pole and then spending an hour plus TRYING to vacuum the pool. The 8' deep end was the worst.... All of this to no avail, as every season we ended up with yellow algae problems, frustrated with our efforts, and put off by the appearance of our water. I was beginning to try to calculate how many dump truck loads of dirt it would take to fill the pool in!! I began to get interested in a pool cleaning robot every time we went in to buy even more chemicals to fix our current pool problem, and finally I decided to take the plunge and buy a robot. This was to be my last effort to make our pool work. We ordered the Nautilus Plus by Dolphin/Maytronics, in March and when it arrived I was not sure this was the way to go. The Dolphin set in our house for a few more weeks until we opened our pool (after all the "helicopter" things were through falling from the Maple trees...) Finally, the day of our pool opening arrived... and we gently placed our Dolphin in the pool, and pushed the start button on the control box....At this point we should cue the music and have a bright spot-light shine on the Dolphin!!! This little monster took off with a vengeance! I was immediately impressed with the amount of water it was moving, and the pristine clear trail it left as it made it's way across the bottom of our pool to the deep end! Maybe 2 to 2 and a half hours later we took it out of our now clean pool, somewhat stunned by it's initial performance! Every one in my family was in awe of it's performance, and we realized that we had, perhaps, turned a corner in our battle to have a clean and inviting pool!Three months in, June 2016, and the Dolphin continues to do an excellent job, and our pool water looks like liquid glass! The Dolphin has become an important part of our pool maintenance regimen, and we use it normally about twice a week to clean the pool. I stress that this is a part of our overall effort to keep out pool in the best shape possible. We still do water analysis and add chemicals... but no where near the same amount as before our Dolphin! We back wash our filter once a week now, so we are saving lots of water, AND most important to me, I no longer have to break my back and take my time to manually vacuum the pool, just let the Dolphin do that thing it does sooooo very well!!!Let me address some of the negative things I have read in the reviews of this pool cleaner...Warranty problems: We have had NO problems with our Dolphin. Right out of the box it has worked like a champion, so I have no comments on the help, support and warranty problems others have posted.Instructions: Yes, the 'bot comes with very little in the way of operation instructions. There is really only one sheet of instructions with drawings on it, that tell how to use the Dolphin... but, if you have even a basic understanding of mechanical things, you should have no problems in making the Dolphin work. Every thing snaps together with ease. Pay attention to how it comes apart and then reverse the process after you clean it... nooooo problems! I guess that Maytronics could do a much better job with the instructions- better drawings and expanded written directions, but I can say I honestly have not had any problems understanding how this critter works. It is very straight forward in construction and operation.Filters: Our Dolphin came with 2 sets of filter cartridges. They are made out of some very sturdy plastic type material and require only a good rinse with the hose to clean. We used the "coarse" set of filters the first time we cleaned the pool, to help get out a few leaves, but from then on, we used the "fine" filter cartridges with great success. We ALWAYS take the time to disassemble the filter cartridges after each use and clean them. We then hose out the inside of the Dolphin to complete the process. Like all things electro-mechanical, normal maintenance and cleaning determine the life of the machine. The filter cartridges are held on the filter frames with 2 rotating snap clips. I think that these could be problematic in the future, but look like they would be easily replaced with a screwdriver if replacement is ever required.Steps and Walls: Yep, try as hard as it might, the little Dolphin is just too big to clean our steps. We just use a brush on an 8' pole to sweep any debris on the steps into the bottom of the pool prior to starting the Dolphin... problem solved. I can gladly spend the minute to sweep the steps vs. the hours plus of time to manually vacuum the pool any day! Our Dolphin climbs right up the walls and runs partially out of the water to clean the pool walls.... it's like it's maaaagic! LOL!Carrier: Our Dolphin Nautilus Plus did not come with a carrier. It does have a very sturdy built in handle that makes carrying it, and getting it out of the pool pretty easy. If you have health problems or back problems, etc. this could be a concern, but we have had no problems here. Also, I have never seen any debris fall out of the unit as I remove it from the pool.That's about all I can think of for right now. Maybe at the end of this pool season, I will follow up with my first season Dolphin results.... stay tuned!I hope this is of help to all thinking about buying a Dolphin. I think this is one of the best purchases I have made in years!!!! We now no longer say we are going to clean the pool with the Dolphin... we now say that we are "RELEASING THE KRACKEN!!!!" LOL! Thank you Maytronics, for allowing me to now enjoy my pool, not just spend hours and $$$ trying to keep it clean!

18x36 inground poolI 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 CleanerEDIT: 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!
