Maytronics Dolphin E10 motor unit S1 floor only black - 9995389-EX

Maytronics Dolphin E10 motor unit S1 floor only black

The Maytronics Dolphin S1 floor-only motor unit (9995389-EX) is the complete drive and suction motor block engineered for floor-cleaning configurations of the Dolphin S-series platform. It houses the propulsion and impeller assembly in a single serviceable unit, restoring full vacuuming and traction performance when the original motor block fails.

Function and design

This self-contained motor block integrates the drive motor and suction impeller into one sealed assembly. Configured for floor-only cleaning, it powers the robot’s movement across the pool floor while simultaneously generating the water flow needed to pick up fine and coarse debris. The floor-only designation means the unit is optimised for flat-surface navigation without the additional torque required for wall-climbing variants.

Compatible Dolphin models

This motor unit is a confirmed genuine Maytronics spare for the Dolphin E10, Dolphin S50, Dolphin T15, Dolphin Active 10, and Dolphin Escape. Always verify your exact model and chassis revision before ordering, as S-series variants may use different motor block configurations.

When to replace this motor unit

Replacement is indicated when the robot powers on normally but fails to move or vacuum, when the unit runs noisily or intermittently, or when the impeller is found to be damaged beyond clearing. A blocked or seized motor block that does not clear after removing debris from the propeller is a reliable sign the full unit requires replacement.

Why genuine matters

Aftermarket motor blocks can introduce dimensional tolerances incompatible with the Dolphin S1 chassis, leading to premature bearing failure or poor water-flow efficiency. Genuine Maytronics parts are manufactured to the exact specification of the original, ensuring correct fit, proper impeller clearance, and maintained warranty validity. Materials are tested to withstand pool chemicals, salinity, and UV exposure over the robot’s service life.
