Abstract: The present application relates to a vacuum cleaner head (10). The vacuum cleaner head (10) includes a housing (40) having a vacuum extraction zone (49), and first and second rollers (20, 30) configured to locate against a surface to be cleaned (60). Each of the first and second rollers (20, 30) is able to pick-up detritus from the surface to be cleaned (60) when they rotate and move over the surface (60) and to carry detritus to the vacuum extraction area (49) in the housing (40). In accordance with the present invention, the first roller (20) is rotatable when moved along the surface to be cleaned (60) in a first direction and restricted from rotating when moved in an opposing second direction. The second roller (30) is rotatable when moved along the surface to be cleaned (60) in the second direction and restricted from rotating when moved in the first direction. The present application also relates to a vacuum cleaner comprising the vacuum cleaner head (10).

Abstract: A rotary brush attachment tool for a hand-held vacuum cleaner having a dust bowl terminating in a nozzle end provides a mechanical force that acts to move foreign matter into the attachment tool from which the foreign matter is drawn into the nozzle end of the dust bowl of the hand-held vacuum cleaner to which it is removably attached.

Abstract: A carpet vacuum cleaning machine and roller attachment apparatus therefor for cleaning and extracting dirt and debris deep below the surface of carpets. The carpet cleaning machine includes a vacuum head or housing operably connected to a vacuum source and a debris collecting member. The roller attachment apparatus preferably replaces the conventional elongated motor-driven roller brushes commonly used in most vacuum cleaning machines. The apparatus includes a plurality of spaced star-shaped spur discs mounted side-by-side for free rotation on an elongated support shaft. As the vacuum cleaning machine is moved across the carpet, the pointed periphery of each disc engages and penetrates into the carpet to separate the carpet fibers to expose dirt below the carpet upper surface thereby allowing more effective vacuum extraction of the dirt.

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.

Abstract: A suction head for a vacuum cleaner includes a rag roll device which is wetted to perform a wet wiping action across the floor. The rag roll device is mounted for rotation about a horizontal axis. A rotation regulating mechanism, comprised of a pawl device and ratchet teeth, is provided which prevents the rag roll device from rotating when the suction head is moved forwardly, while permitting the rag roll device to rotate by a predetermined angle when the suction head is moved rearwardly. This enables different portions of the rag roll device to assume a floor-contacting position.

Abstract: A vacuum cleaner includes a housing having a suction opening disposed between front and rear brushes for sucking dirt from a floor. A rag disposed behind the rear brush is rotatably driven about a transverse axis by the reciprocal action of the housing as the latter is displaced along the floor. A water supply keeps the rag moist. The rag is driven such that the floor-engaging portion is driven in a direction opposite the direction of housing travel. An auxiliary opening in the suction line sucks dirt from the rag at a location above the floor.

Abstract: A nozzle assembly for a vacuum cleaner is provided with floor engaging wheels that are frictionally engaged with and rotate additional wheels that are secured to the ends of a brush in a manner such that rotation of the additional wheels causes the brush to rotate. As the vacuum nozzle assembly is moved back and forth across a floor that requires cleaning, the wheels engaging the floor are caused to rotate thereby rotating the brush in the opposite direction. The latter agitates the carpet or other floor covering to loosen and direct dirt particles toward the inlet slot of the vacuum cleaner nozzle.
