Maytronics Motor Unit for Dolphin S200, S300 and S300i

The Maytronics 99953058-EX is the replacement motor unit for the Dolphin S200, S300 and S300i robotic pool cleaners. The motor unit is the working core of the robot: it drives the tracks and pumps water through the filter, so when it fails the cleaner sits still even though the power supply lights up.

Before you order

Rule out the cable and the power supply first, since both are cheaper and either can leave a robot dead in the water. If those check out and the cleaner still will not move or pull water, the motor unit is the fix. Confirm your model is an S200, S300 or S300i.

This is the motor unit only. The cable, power supply, filter panels and brushes carry over from your existing cleaner.
