1. A vacuum cleaner comprising:
- 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;
a sensor configured to measure one or more parameters that directly correspond to a flow rate of the suction air stream; and
a control unit 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 based on the measured one or more parameters that directly correspond to the flow rate of the suction air stream so that the suction power at the vacuum attachment is controllable at a predefined level.

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.
