Abstract
A wheel driven suction nozzle having an upper body attached to an under body. An opening is formed at a front of the upper body which provides access to a suction cavity. An agitator covered with a fluff material is removably rotatably mounted within the cavity and extends partially out a bottom of the under body to clean and shine bare floors. A cover is hingedly mounted to the upper body and movable between an open position which provides access to the cavity and allows for removal of the agitator, and a closed position which covers the cavity and prevents removal of the agitator. A cogged front pulley is attached to one end of the agitator. A cogged belt is driven by a rear cogged pulley and engages the front pulley whereby rotation of the rear pulley rotates the agitator. A front gear is rigidly connected to the rear pulley and engages a rear gear which is rigidly connected to an axle shaft. A pipped wheel is attached to each end of the axial shaft whereby rotation of the wheels rotates the rear gear which, in turn, rotates the front gear, the rear pulley and thus the agitator.
