Maytronics Dolphin Ex 45 CB lower cover 2010 - 9980700

Maytronics Dolphin Ex 45 CB lower cover 2010

This is the genuine Maytronics lower cover (cubierta inferior) for the 2010-platform Dolphin robotic pool cleaner, specifically listed for the Dolphin Ex 45 CB. It forms the structural underside of the robot body, enclosing and protecting the drive and brush assemblies while the cleaner operates on the pool floor. Cross-compatibility with other 2010-platform models — including the Dolphin C3, C4, Supreme M4, M400, M5, M500, Wave 65 and Wave 90 — makes this a widely applicable genuine spare.

Function and role in the robot

The lower cover seals the base of the robot housing, maintaining the correct water-flow path through the cleaning chamber and keeping internal components — drive motors, brush shaft bearings and impeller housing — protected from debris intrusion. A properly seated lower cover is essential for the robot to generate sufficient suction and move predictably across all pool surfaces.

Compatible Dolphin models

This part is the OEM lower cover for the 2010 mechanical platform. Confirmed compatible models include the Dolphin Ex 45 CB (primary application), Dolphin C3, Dolphin C4, Maytronics Supreme M4, Supreme M400, Supreme M5, Supreme M500, Wave 65 and Wave 90. Always verify your robot’s platform revision before ordering.

When to replace the lower cover

Replace this cover if you find visible cracks, warping or broken retaining clips on the underside of the robot body; if the robot loses suction despite a clean filter; or if water bypasses the cleaning chamber, causing erratic travel patterns or poor wall coverage. Physical damage to the cover can also allow debris to contact internal drive components, accelerating wear.

Why genuine Maytronics matters

A genuine Maytronics lower cover is moulded to the exact dimensional tolerances of the 2010 platform, ensuring the correct fit between cover, brush housing and body frame. Non-genuine alternatives frequently introduce gaps that disrupt hydraulic performance, and fitting them may void any remaining Maytronics warranty on the robot.
