Maytronics Dolphin Supreme M5 transparent brush safety cover - 9980892

Maytronics Dolphin Supreme M5 transparent brush safety cover

This is the OEM transparent brush safety cover (part 9980892) for the Dolphin Supreme M5 robotic pool cleaner. It sits over the active brush assembly, shielding the rotating brush mechanism from direct contact with pool walls, fittings, and swimmer limbs while allowing full visibility of brush movement through its clear body.

What this brush safety cover does in the Dolphin

The brush safety cover acts as a protective guard around the active brush cylinder. It channels water flow across the brush while preventing hair, cables, and pool fixtures from making direct contact with the spinning brush. Without it, the brush assembly is exposed to snagging damage and presents a contact hazard. The transparent construction lets you inspect brush condition and rotation without removing the cover.

Which Dolphin models it fits

This cover is listed in the official Dolphin Supreme M5 parts schematic at position 17 and is confirmed to fit the Supreme M4, Supreme M5, Supreme M5 Liberty, Supreme M400, and Supreme M500. Always cross-reference your robot’s parts diagram before ordering to confirm fitment with your specific build variant.

Signs it needs replacing

Inspect the cover when you notice the brush assembly catching on pool features, or if the robot returns visible brush contact marks on pool surfaces it previously cleaned cleanly. A cracked, warped, or snapped cover no longer contains the brush geometry correctly — the brush can flex outward, accelerating wear on both brush and chassis. Any cover that no longer clips firmly to the frame should be replaced immediately.

How to install it

Turn the robot upside down and drain it. Unclip the retaining tabs on the existing cover — no tools required. Align the new cover over the brush assembly with the locating lugs seated in the chassis slots, then press firmly until all tabs click into place. The whole swap takes under five minutes and requires no specialist equipment.
