Side Brush Motor Module
The side brush module contains a small DC motor and a gearbox that reduces speed while increasing torque. Hair and fine fibers often migrate past the shaft seal, wrapping around the drive spindle and creating a mechanical jam that overheats the motor windings or strips the internal nylon gears. Replacing the entire module restores the mechanical drive and electrical integrity of the side brush system.

Replacement Side Brush (5-Arm)
The side brush is secured to the motor spindle via a keyed hexagonal or square socket. If the brush hits a rigid obstacle while the motor is under high torque, the internal plastic socket can strip out, allowing the motor spindle to spin freely inside the brush without transferring motion. A new brush ensures a tight mechanical interface between the drive shaft and the sweeping arms.

Mainboard
If the side brush motor stalls and the internal protection circuit fails, the resulting current spike can blow the surface-mount MOSFET (transistor) on the mainboard responsible for the side brush circuit. This results in a total loss of power delivery to the motor terminals. This is the likely culprit if a known-good motor module still fails to rotate after installation.
