Abstract
A system comprising a vacuum cleaner and a base station, wherein the vacuum cleaner has a suction opening for sucking up dirt and/or dust from a floor by a suction air flow, a fan for producing the suction air flow, a dust chamber for holding dirt and/or dust, and an air outlet opening such that air sucked in together with the dirt and/or dust can be discharged again. The base station can be connected to the vacuum cleaner in such a way that the dust chamber can be emptied into the base station by means of an air flow. The air flow used to empty the dust chamber can be produced and blown into the dust chamber by the fan for producing the suction air flow. The base station has a return channel, through which the air flow exiting the dust chamber can be guided back into the vacuum cleaner.
