Abstract
A vacuum cleaner includes a drive unit configured to generate a suction air stream, a vacuum attachment, a separator device disposed between the vacuum attachment and the drive unit and a control unit. The control unit is configured to influence an input power to the drive unit as a manipulated variable so as to control the suction power at the vacuum attachment as the controlled variable. The suction power at the vacuum attachment is controllable at a predefined level.
