Abstract
The invention is directed to an attachment nozzle for a vacuum cleaning system such as a vacuum cleaner or the like which includes a rotating brush. A modular step-up gear transmission is interposed between the brush and the air turbine which runs in the suction air stream. The attachment nozzle includes an outer ring region wherein a plurality of air-inlet apertures are formed which are covered either partially or entirely by means of a ring-shaped body which is rotatably mounted on the end portion of the housing. A cup-shaped recess is formed centrally of the plurality of air inlet openings and defines a cup-shaped recess for receiving the modular gear transmission therein.
