Abstract
A method for operating a vacuum cleaner includes providing a vacuum cleaner including a motor-driven fan, a pick-up device configured to pick up an air-dust mixture that is disposed on a suction side of the fan, a dust separator including at least one cyclone separator and a valve element disposed between the pick-up device and the fan. The dust separator is disposed between the pick-up device and the fan. The valve element is operated so as to connect a flow path leading from the pick-up device through the at least one cyclone separator to the fan only when a predefined minimum value of a volume flow generated by the fan or a quantity correlating with the volume flow is present.
