Brush Roll Micro Switch
This internal switch completes the circuit to the brush motor only when the vacuum handle is reclined. Over time, the mechanical lever can bend or the internal contacts can suffer from carbon arcing, preventing power from reaching the nozzle motor regardless of the handle position. Replacing this switch restores the electromechanical logic required for the brush roll to actuate.

Replacement Brush Roll
Accumulated debris and hair wrap create significant rotational resistance and friction-induced thermal energy. This heat can cause the plastic bearing seats to deform or the bearings themselves to seize, physically preventing the motor from turning the assembly. A new brush roll provides fresh bearings and balanced rotational dynamics.

Nozzle Cogged Drive Belt
The cogged belt transfers torque from the small nozzle motor to the brush bar. While these belts are reinforced, a sudden jam can shear the cogs or snap the internal cords, severing the mechanical link. If the motor is heard running but the brush is stationary, the belt has lost its structural integrity.
