Maytronics Dolphin C6 CB brush assembly grey dynamic - 99955340-ASSY

Maytronics Dolphin C6 CB brush assembly grey dynamic

This is the genuine Maytronics brush assembly (part 99955340-ASSY) for the Dolphin C6 CB and the wider Dynamic CB range of robotic pool cleaners. It is a complete, ready-to-fit assembly that restores full scrubbing contact across pool floors, walls and the waterline, ensuring efficient debris pick-up and filtration cycle performance.

Function and design

The brush assembly mounts directly to the underside of the cleaner and works in tandem with the drive tracks to agitate settled debris into suspension ahead of the intake port. The grey bristle segments are arranged to maintain uniform contact pressure across both flat and curved pool surfaces. The DYN-C.B designation indicates this is the Dynamic climbing-brush variant — engineered to maintain traction and scrubbing efficiency on vertical walls as well as the pool floor.

Compatible Dolphin models

Maytronics lists this assembly as compatible with a broad range of Dolphin Dynamic series robots including the Dolphin C6 CB, Dolphin Sigma, Dolphin M400, Dolphin M500, Dolphin Wave 60, Dolphin Wave 80, Dolphin Nautilus CC Supreme, Dolphin C5 PRO, Dolphin Pro X1, Dolphin Active X4, Dolphin Active X5, Dolphin KAPTUR 400, Dolphin KAPTUR 500, Dolphin Zenit 20, Dolphin Zenit 30, Dolphin DIVER PRO 400, Dolphin DIVER PRO 500, Dolphin X90, and several Evolution and Wave 30 variants. Always cross-reference your robot’s model number before ordering.

Signs that the brush assembly needs replacing

Replace this assembly when you notice reduced debris collection despite the robot completing its full cleaning cycle, visible bristle wear or flattening, uneven scrubbing marks on the pool floor, or reduced wall-climbing ability. A worn brush assembly forces the motor and filtration system to work harder, accelerating wear on other components.

Why genuine Maytronics parts matter

Aftermarket brush assemblies are frequently made to looser dimensional tolerances and with lower-grade polypropylene, causing premature bristle fatigue and imprecise fitment that degrades suction efficiency. Genuine Maytronics parts are manufactured to the same specification as the original equipment, preserving the cleaner’s rated cleaning coverage and protecting the warranty.
