Abstract: A vacuum cleaner having a hose (13) which is connected to a vacuum cleaner housing, the outer end of the hose having a tube handle (12). The tube handle is connected to a nozzle (10) by a tube shaft (11). The tube shaft (11) is movable relative to the tube handle (12), and can be releasably locked in different positions. A device is conveniently provided to allow the operator to adjust the relative length of the tube shaft by moving the tube shaft relative to the tube handle.

Abstract: A vacuum cleaner nozzle having a first nozzle part (11) which has brush elements (23) or the like facing the floor and a second nozzle part (25) which is movably arranged with respect to the first part (11) and which has at least one suction opening (27) through which air flows to an outlet tube (13) connected to the nozzle. The second nozzle part (25) is supported by the first nozzle part (11) by means of a resilient element (31). The resilient element maintains the second part (25) above the floor when the nozzle is moved on a hard surface and allows the second part (25) to move toward the floor when the nozzle is moved on a soft surface, such as a soft carpet.

Abstract: In a vacuum cleaner having a disposable dust bag of the kind comprising an attachment plate of cardboard or the like, and a cover adapted to be opened for the replacement of the dust bag, a blocking device is provided which is adapted to prevent closing of the cover when the dust bag is missing. The blocking device includes a slide actuated by a spring to be moved to a first position in which the closing of the cover is prevented, and a toggle-joint mechanism adapted to be actuated by the attachment plate to move the slide to a second position for permitting closing of the cover.
