  • Question
    What is the purpose of the floats on the handle of the cleaner?
    Answer
    The floats are on the arm of the Dolphin. The floats are used to assist the buoyancy of the cleaner when turning on the bottom of the pool and scrubbing the waterline. To adjust the buoyancy, slide the float out on one side of the Dolphin. If the cleaner continues to have issues turning or scrubbing the waterline, pull the opposite float outward as well.

    2 out of 5 The Warranty is worthless.

    Cameron

    My Sigma broke within 11 months of use and Maytronics refused to repair claiming that it does not warrant parts that wear out. Of course, I was told it was the best warranty in the industry and it was no hassle. If you want a bot that works for a year, buy this one.

    5 out of 5 Works great!

    Roger Lowe

    The one I ordered from Amazon had a defect – its handle was detached. I called Maytronics customer support and they had a new one to me two days later. I then returned the defective one to them with free shipping. Their customer support was fantastic.

    I’ve had the new Dolphin Sigma for a week now and am very pleased with it. It does a fantastic job cleaning the pool bottom, sides, bench and tile above the water line. I still have to sweep the tanning ledge since the Sigma isn’t supposed to be operated in less than 2 1/2 feet of water. I haven’t had many leaves, but the few I had were picked up easily. There have been several bad reviews about the remote. I didn’t get it because I have a smart phone and downloaded the Dolphin app. The app is limited but it does a good job maneuvering the Sigma in manual mode. I use it to move the Sigma onto a pool bench, then powering it off so I can easily remove it from the pool. I’ve had no problems connecting my iPhone via bluetooth to the power supply. Contrary to some other reviews, my Sigma has had no problems with my raised drains. It goes over them as if they weren’t there. One thing I haven’t seen in the other reviews is that the Sigma also works in a spa. It has no problems cleaning my unground spa, which I was unable to do with my other cleaner. I could not be more pleased with it.

    2 out of 5 Could be better

    Mike Sheets

    I’m surprised at how easily this unit gets stuck. With all the motors and gyro, i would have thought it would be better, but during a typical 2 hour run, it gets stuck 2-3 times on my floor drains or steps. For the amount of money this costs, I’m not sure its ‘superior’ to the other models. I raised a support ticket without any satisfaction, the only recommendation was to ‘add ramps to my floor drains’. Now, support won’t even reply to my email.
