Abstract

The vacuum cleaner is provided with a housing (1) containing the motor fan chamber (9), the dust filter chamber (7) and the coil chamber (11) containing the winding mechanism for the cable. A by-pass opening (24) which leads from the pressure side of the motor fan (10) into the interior or the housing (1) opens into the coil chamber (11) whilst several outlet openings (25, 26, 27) which lead from the housing chamber to the outside are provided in at least two of the walls (21, 22, 28) which define the coil chamber (11). The motor fan (10) and the winding mechanism (30) are thereby mounted independently of the remaining set-up in the housing so that an optimum centre of gravity is achieved. The winding mechanism which is preferably made of plastics thereby dampens the noise of the filter air as it passes through so that further sound-proofing means.
