Abstract (en)
A filtering device for a vacuum cleaner comprises: a casing having a collecting space therein, a suction opening through which air including dust is sucked and a discharge opening through which purified air is discharged; a filter installed at the internal space of the casing, for filtering dust from air sucked through the suction opening; and a filter cleaning unit disposed to encompass an outer circumferential surface of the filter, for cleaning the filter by being rotated by a rotation force of air sucked through the suction opening. Accordingly, the filtering device can remove fine dust attached to the filter in a cleaning operation, thereby preventing a channel of the filter from being closed with the dust.
