Geared Brush Roll Drive Belt
The geared belt transmits rotational torque from the nozzle motor to the brush roll. If a rug or object jams the roll, the motor's drive gear will continue to spin, often shearing the teeth off the belt or snapping it entirely to protect the motor from burnout. This results in the motor spinning audibly while the brush roll remains stationary.

Floor Nozzle Motor
The independent DC motor located within the floor nozzle is responsible for brush rotation. Over time, carbon brush wear or winding failure due to excessive heat (from operating with a partially jammed roll) will prevent the motor from initiating. Replacing the motor restores the electromechanical drive required for agitation.

Replacement Brush Roll
Hair, string, and carpet fibers frequently migrate into the end-cap bearings of the brush roll. This creates high frictional load that can seize the assembly or cause the drive belt to slip. A new brush roll assembly provides fresh, low-friction bearings that allow the motor's torque to be fully utilized for rotation.
