Maytronics Motor Unit For Dolphin M400/M500 Pool Cleaners

The professionals at pool zone had my part in stock and had it to me the next day!!

This replacement did the trick for me. The item was sent and arrived very timely. I replaced the part myself and was back in business. $400 repair vs $1600 whole unit replacement! As long as parts are available for this M400, I can run it indefinitely.

Received motor very quickly to California and was an exact replacement. I did have to find out motor number from Maytronics and this is who they recommended for purchase.

I have installed the dolphin matronics Sigma motor unit and my pool cleaner works like brand new at a quarter of the price of a new one. The item was packaged securely and arrived in great shape. Great company to do business with. I will definitely do business with them again. I highly recommend pool zoom.

This part fit perfectly in my M400, the swap was straightforward with some youtube help and it functions perfectly.

The part fit perfectly and works as designed

I'll never know how the motor would have performed. I had it installed by my dealer, but the pool cleaner still did not move or vacuum. Unfortunately, the unit is not returnable once it is used. Probably a good product, but not a good return policy. I should have checked Amazon.
