Dolphin Proteus DX5i

  • Waterline Scrubbing - Super efficient on vertical surfaces for optimal waterline scrubbing
  • Light Weight - Lightweight design for easy lifting and handling
  • Easy Access Filter - Top-load filter access for easy and convenient debris removal and cleaning
  • Plug'n'Play - Just plug it in, drop into the pool, for a hassle free clean

The Dolphin Proteus DX5i features waterline cleaning and anti-tangle swivel technology, along with high-speed brushes for enhanced pool coverage. Although it offers convenient Plug'n'Play functionality, the lack of multiple filtration options and limited warranty may be drawbacks for users who require robust, long-lasting solutions. Suitable for pools up to 50 feet, the DX5i delivers efficient wall and floor cleaning, but the absence of a smartphone app and more advanced filtration capabilities may leave some users looking for a more feature-rich cleaner at a similar price range.

We’ve had this for exactly 1 year and it suddenly stopped working. We have kept it clean and taken great care of it, so there shouldn’t be any reason for it to just quit. Once it’s turned on it will go forward and then backwards and then the red light of death appears on the control board. I paid over $1000 for this vacuum and shouldn’t be having these issues. I would stay far away from this brand and/or model.

It is a nice upgrade from my old Dolphin remote does not work as well as I expected. If you just run it in the basic mode it works fine. Don't spend the extra money on the i function.

Mike C. - 4 Stars

I had an in floor cleaning system that I relied in for almost 5 years. Live in a dusty windy area. My pool was never clean. After running two 2 hour cleaning cycles, the pool is spotless. I couldn’t believe the fine dust, sand and debris that the unit picked up. I now have the pool I always wanted. Now for the bad news. If you are looking to actually control everything via WiFi think again. If the app worked the way it was supposed to work this would be a 5 star review. I can only get it running by manually starting the unit. WiFi and Bluetooth signals are strong while the functionality is weak. Would still recommend if it is a chore keeping your pool clean and clear.
