Dolphin Maytronics M400 Stops Then Flashed Green

  • Cleaning Performance-1 pts

    They aren't designed to remove really big bulky stuff like tree debris.

    It uses clever clean technology to scan the pool and create an ideal cleaning route so it doesn't miss spots or linger too much in one area.

  • Filter & Debris Basket0 pts

    If your pool is near trees and gets lots of leaves, you'll have to empty these cartridges out several times during a cleaning job because they'll just fill up that fast.

  • App & Controls+5 pts

    We really like the My Dolphin app that comes with the M400.

    I can honestly say this thing helped clear my pool much faster. It picked up sand I couldn't even see with the naked eye.

  • App & Controls+1 pts

    It connects to my WiFi all the time (the controller is about 100ft from my closest Orbi satellite). I've been able to run the robot while I'm out.

  • Setup & Ease of Use-1 pts

    I agree, the instructions were pretty crappy. I used YouTube videos.

    there is ZERO mapping taking place. The robot continuously goes to the same spots over and over again and doesn't seem smart at all.

  • App & Controls-1 pts

    Wifi is terrible. It barely connects to my wifi and drops off almost immediately.

  • Setup & Ease of Use-1 pts

    Instructions — for a $2000 robot, the manual it came with is laughable.

    I would say that it does do a good job scrubbing. If you've got like stubborn stains and stuff like that
