    摘要： An auxiliary suction tool for a vacuum cleaner comprises a main body having an elongated flattened tubular shape. One end of the body is connected to a vacuum cleaner hose, and the other end thereof is terminated in a flattened air intake opening. Each flat side of the body has a guide slot and a plurality of engaging aperatures. Selectively inserted into the flattened air intake opening is a pair of brush attachment frame with brushes having a fixed length on one end thereof. Each brush attachment frame has a guide member slided along the guide slot of the body and a semi-spherical projection selectively engaged with one of the aperature of the body, respectively, selectively adjusting the brush length depending on the desired cleaning purposes.

    摘要： A vacuum cleaner nozzle comprises a body (10) having a suction passageway (11) extending therethrough, both ends of said passageway being adapted to receive a suction conduit (20). One end of the suction passageway is surrounded by a dust-brush (12) and two rotatable wing members (13) are provided at the other end. Each of the wing members comprises a resilient means (15) provided with a fiber picking material (16).

    摘要： A nozzle for a vacuum cleaning apparatus having two movable working members, that is a brush nozzle and flat surface nozzle which can be alternately brought into contact with a working surface, such as a floor, by means of an actuating member operating between two end positions. A blocking means is arranged to block the actuating member in either of the end positions. The flat surface nozzle is arranged to be lowered to a position on the working surface in which the flat surface nozzle is located below the front edge of the brush nozzle in order to pick up dust and dirt near vertical surfaces.

    摘要： An extraction head for a cleaning machine is disclosed for traveling along a cleaning path on a variable-height floor. The extraction head comprises a body including a floor-facing surface and an extraction aperture disposed in the floor-facing surface. The extraction head comprises a vacuum outlet in fluid communication with the extraction aperture. The extraction head comprises an adjustable-height brush positioned in front of the extraction head body along the cleaning path. The adjustable-height brush is configured to translocate upwardly and downwardly as the extraction head moves along the cleaning path on the variable-height floor. The adjustable-height brush may comprise a proximal end and a distal end opposite the proximal end. The proximal and distal ends may be configured to translocate upwardly and downwardly relative to each other as the extraction head moves along the cleaning path on the variable-height floor.
