Abstract: An apparatus for a vacuum cleaner for compensating air pressure fluctuations includes a main body through which an air flow is flowable in a flow direction, where the main body contains a passage opening, and a separating element, where the passage opening is separated from ambient air by the separating element. The separating element is movable such that, as a result of a movement of the separating element in a radial direction, a reservoir which receives an air volume is produced between the main body and the separating element such that a vacuum produced in the main body by the air flow is at least partially maintained.
