Side Brush Motor Module
The s9 side brush motor is a self-contained module prone to ingress of fine particulates and hair which wrap around the drive spindle. This ingress increases torsional resistance, eventually stripping the internal nylon reduction gears or causing the DC motor's windings to overheat. Replacing the entire module is the standard resolution as the gearbox housing is not designed for non-destructive disassembly.

Corner Brush (3-Pack)
Deformation of the brush plastic or a stripped internal hex socket where the brush meets the motor shaft can cause the brush to slip or fail to rotate even if the motor is turning. Inspecting the physical interface between the brush and the motor shaft is necessary to rule out a simple mechanical coupling failure. If the socket is rounded out, the motor shaft will spin inside the brush without transferring torque.

Side Brush Motor Screws
The corner brush is held onto the motor spindle by a single screw that can vibrate loose during standard operation. If the screw is missing or loosened, the brush will lose contact with the drive spindle and stop rotating. While less likely than a motor failure, a simple mechanical detachment of the accessory is a potential secondary cause.
