A vacuum cleaner glides across floors, pulling dust and small particles into its collection area. The hose conveys air and debris toward the main unit, where dirt becomes visible in a canister or bag. Users track the filling level and listen to the steady hum of the motor.

These elements remain in plain view during operation. The floor nozzle presses against the surface, aiding pickup.

Within this nozzle, a brush roll rotates to agitate fibers and dislodge embedded particles. The brush roll turns continuously inside a covered compartment. Its motion stays out of direct sight, shielded by the nozzle housing.

A belt from the motor powers the brush roll, maintaining its spin throughout the cleaning pass. This internal rotation persists alongside the observable suction and collection.

The vacuum cleaner operates fully, with the brush roll active yet removed from ongoing observation.
