The MAYTRONICS 99953051-ex is a direct-replacement motor unit designed for the Dolphin M200 (E55) and Nautilus CC Plus robotic pool cleaners. This assembly serves as the core drive component of the cleaner, powering the unit's movement and filtration function within the pool. Pool service technicians and repair shops install this part when the original motor unit has failed or lost performance. The replacement restores full operation to the cleaner without requiring a full-unit swap, making it a cost-effective repair option for supported models.
This motor unit is intended for use with two specific robotic pool cleaner models: the Dolphin M200 (also referenced as the E55) and the Nautilus CC Plus. It is suited for residential pool service applications. Technicians should verify the cleaner model before ordering, as this motor unit is designed exclusively for these two cleaners and will not fit other Dolphin or Maytronics models.
Compatible with the Dolphin M200 (E55) and Nautilus CC Plus robotic pool cleaners only. This motor unit will not fit other Maytronics or Dolphin cleaner models. Confirm the cleaner model before installation.
Installation should be performed by a qualified pool service technician familiar with robotic pool cleaner repair. Before beginning, disconnect the cleaner from its power supply unit and remove it from the pool. Consult the cleaner's service documentation for proper disassembly and motor unit removal procedures. Do not attempt to power the cleaner during any stage of motor unit replacement.
