Maytronics Dolphin 2010 CLS8 impeller cover black - M96330088

Maytronics Dolphin 2010 CLS8 impeller cover black

This is the genuine Maytronics black impeller cover for the 2010 CLS8 motor unit, fitted to Dolphin commercial-class robots including the Dolphin 4 IoT CB QP NC and the Dolphin Wave 80 series. The impeller cover sits flush over the impeller chamber within the motor unit cover assembly, sealing the hydraulic pathway that draws water — and suspended debris — up through the robot and into the filter basket.

Function and role in the motor unit

The impeller cover forms the top seal of the 2010-series motor unit’s pump chamber. It retains water pressure around the impeller, ensuring maximum flow rate and suction efficiency. Without an intact cover, the impeller loses hydraulic back-pressure, causing a measurable drop in filtration throughput and leaving fine debris uncaptured.

Compatible Dolphin models

This part is confirmed for the Dolphin 4 IoT CB QP NC and the Dolphin Wave 80 (commercial), both of which use the 2010 CLS8 motor unit assembly. If your robot uses the MU DYN 2010 COMM motor unit variant, verify the exact motor unit designation on your unit’s label before ordering, as related 2010-series covers share a similar profile but are not always interchangeable.

Symptoms that indicate replacement is needed

Visible cracking, warping or a missing tab on the impeller cover will cause the cover to sit proud of the assembly rather than flush, breaking the hydraulic seal. Symptoms include noticeably reduced suction, incomplete debris pickup on the pool floor, or an audible change in pump tone. Inspect the cover each time you remove the top assembly for impeller cleaning.

Why genuine Maytronics parts matter

The 2010 CLS8 cover is moulded to exact dimensional tolerances so that it seats flush within the cover assembly without gaps. Aftermarket copies frequently differ in wall thickness or clip geometry, allowing bypass air to enter the pump chamber and reducing suction performance. A genuine Maytronics part guarantees the correct fit, maintains the robot’s original hydraulic efficiency, and preserves any remaining service warranty on the motor unit.
