Main Brush Lifting Motor Assembly
The S8 Pro Ultra utilizes a dedicated electromechanical actuator to raise and lower the dual-roller brush module. Failure occurs when the internal gear teeth (typically plastic) strip or when fine dust bypasses the seals and creates high frictional resistance in the worm gear drive. Replacing the motor assembly restores the mechanical advantage needed to actuate the riser cam against the spring tension of the brush housing.
