Maytronics Dolphin Select 630 IoT brush support - 9980922

Maytronics Dolphin Select 630 IoT brush support

This is the OEM brush support (support de brosse) for the Maytronics Dolphin Select 630 IoT, listed under the Supreme M5 platform. It is the structural bracket that locates and retains the active brush assembly inside the cleaner’s chassis, holding the brush at the correct angle and height against the pool surface during every cleaning cycle.

What this brush support does in the Dolphin

The brush support carries the active brush axle and transmits rotational load from the drive gear to the brush roller. Without a correctly seated support, the brush cannot maintain consistent contact pressure against the pool floor and walls, causing uneven scrubbing or complete loss of active brushing. The support also absorbs lateral stress so the brush bearings are not overloaded.

Which Dolphin models it fits

This part is confirmed for the Dolphin Select 630 IoT and the Supreme M5 platform. Research shows SKU 9980922 is cross-listed as a brush supporter for the Supreme M5, M400, M500, C3, C4, Oasis Z5, Triton Plus, Wave 65, and Wave 90. Confirm your exact model and serial number before ordering, as brush support geometry can vary across production runs of closely related models.

Signs it needs replacing

The most obvious sign is the active brush visibly skewing to one side, sitting proud of the chassis, or refusing to spin freely even after the brush roller and bearings are confirmed serviceable. You may also notice the support is cracked, has a sheared retaining lug, or the pivot point is worn enough to let the brush rock under load. Any of these conditions will reduce wall-climbing performance and leave visible tracks of uncleaned surface.

How to install it

Access the active brush bay by removing the top cover and unlocking the brush assembly — typically two to four screws depending on the exact variant. Slide the old support off the axle, transfer any spacers or clips to the new support, and press it firmly into its locating channel until the retaining lugs click into place. Refit the brush assembly, confirm it spins without binding, then close the cover. The full job takes around 15 minutes with a Phillips screwdriver.
