The invention relates to a method for cleaning filters of a vacuum cleaner having a dirt collecting container, which has a suction inlet and is in flow connection with at least one suction unit via at least one filter and at least one suction extraction line, and at least one external air inlet which opens into the suction extraction line downstream of the filter and can be closed by means of a closing valve. The closing valve has a movable valve body acted upon by a closing spring with a closing force and, in the closed position, additionally by a magnetic holder with a magnetic holding force. In order to clean the filter, at least one closing valve is opened and the side of the filter oriented away from the dirt collecting container is impinged upon by external air. A vacuum cleaner for carrying out the method is also provided.
