Maytronics Dolphin Supreme M5 float and housing assembly - 9991049-ASSY

Maytronics Dolphin Supreme M5 float and housing assembly

This is the complete float and housing assembly (kit) for the motor unit (MU) of the Dolphin Supreme M5 robotic pool cleaner. It combines the buoyancy float with its protective housing in a single bolt-on assembly, maintaining the correct attitude of the cleaner in the water column throughout every cleaning cycle.

What this float and housing assembly does in the Dolphin

The float and housing assembly provides the controlled buoyancy that keeps the Supreme M5 motor unit correctly orientated as the robot traverses the pool floor and walls. Without the right upward force at the motor unit, the cleaner loses its designed balance, navigation becomes erratic, and cleaning coverage suffers. This assembly restores that precise float geometry to OEM specification.

Which Dolphin models it fits

This assembly is confirmed for the Dolphin Supreme M5, Supreme M5 Liberty, Supreme M400, Supreme M500, Oasis Z5, and Triton Plus — all of which share the same MU Supreme platform and the 9991049-ASSY part number in their official spares schematics. Verify your model before ordering; it does not fit earlier Supreme generations outside this platform.

Anzeichen dafür, dass es ausgetauscht werden muss

A cracked or waterlogged float housing causes the motor unit to sit lower than designed, making the robot tip, stall on walls, or circle erratically without completing its programmed pattern. If you see the cleaner consistently listing to one side or failing to climb walls it previously managed, inspect the float and housing assembly first — it is one of the most common mechanical failure points on this platform.

So installieren Sie es

The assembly is a direct-fit replacement that attaches to the motor unit chassis using the existing mounting points — no cutting or drilling required. With the robot on a dry, flat surface, release the existing float and housing from its retaining clips or screws, align the new assembly, and secure it in place. The entire swap takes around ten minutes with a basic screwdriver.
