Abstract (en)
[origin: EP0461443A1] The invention relates to a vacuum cleaner (1) with a noise-reducing part (7) which is attachable to the motor (2) of the blower aggregate and surrounds the motor housing, leaving a flow space free. The space requirement for the storage of the noise-reducing part (7) can be reduced considerably in that the noise-reducing part (7) is plate-shaped and is provided with wedge-shaped incisions (10) which allow hood-shaped deformation and extend from the circumferential edge with their tip towards the centre of the part.
