DOLPHIN Cayman Robotic Inground Pool Cleaner

This definitely worth every dime!! Wish i had bought sooner! Cleans sand, leaves, and algae!! Goes up walls and is just amazing! We used it just after opening our above ground pool and ran twice bcuz debris was so bad! It cleaned everything without burning up our Pool filter! Very user friendly and very easy to clean!! My husband is a super penny pincher but when he didn't have to hook up a vacume and take apart the pool filter to clean 500 times just to clean the pool he was thrilled!! He said we shoulda bought a long time ago!!! Would have saved us hours of cleaning ourself!

I should have purchased a long time ago. It cleans so nice, fast, it absolutely awesome. Climbs the walls, scrubs the tiles and it’s amazing

I love the robot. I initially wanted a cordless, but after extensive research and reviews the power is just not there, so I went corded with this model. I also purchased an ultra fine filter basket since my dogs track fine dirt in. The thing is a beast and very happy for the price.The only negative I have is unlike some other models/mfgs this does not have a mechanism to keep the cord from tangling. Every couple days when I empty and spray off the ultra fine filter, I have to unhook and un coil/tangle the cord. That is a pain. If they have a next step up model that has that feature and it is not much more $ I recommend that.

my unit is not moving right, will not go all over pool, and cord keeps twisting up and will not straightened out, i need a replacement

We bought this unit in July 2016 and it worked great the first season. We kept it out of the rain, followed all the instructions, and other than the cord getting tangled, the unit was a great replacement for the old Polaris we had that wore out. Plugged it in to open the pool last month, and it will not work properly. The unit moves forward about 3 feet, then backward, then just stops. I tried everything to fix it, but cannot get it to work now. The electronic boards are fine, there is no corrosion or damage to the motors, and the darn thing should work! I've tried contacting Maytronics with no success -- Their warranty registration doesn't even recognize the serial number. My next step is to contact Pool Express (the seller) and see if I can either get a replacement unit or repair parts. I've read other reviews about the Maytronics cleaners and their consistently unreliable operation -- $700+ is a lot of money to spend on a motor, motherboard, and piece of plastic that only lasts one season. I'd advise against purchasing this and look for something more reliable.

Easy to set up, works with schedule and great for big pools. Really love the purchase!

Cleaner did a good job cleaning the pool with the exception of stairs. It does not clean stairs and benches well. Overall I like its simplicity and operation but not its durability. My cleaner quit after 16-months which is less time than I feel then my $800 dollar price tag justifies. It may have died after being left outside the pool in hot sun I'm guessing Electronics may be suceptable to summer heat. That being the case, I may purchase another dolphin unit, but different model, that is long established with strong reviews. Next, I will make the effort to not leave it in direct summer sun while not in pool. My feeling is overall the dophins are good but this particular model needs some durability improvements.

What a great little robot. We gave it a big job and it just keeps working. Very pleased.50,000 gallon saltwater pool, with 10,000 gallon zero edge overflow tank. We just drop it in both and it cleans everything. Walks up the sidewalls, even crawls up on in pool steps and cleans them.
