The striking member of the device is made with a capability of its actuation by a mechanical gear striking the filtering element for removal of a dust from it. The dust is gathered in the chamber for the litter collection together with the large particles of the litter, and the gear of mechanical actuation can be run manually. The gear of mechanical actuating contains an elastic element acting as a lug-latch, which at applying a sufficient force to it passes from the first stable state into the second state. To given device is used to equip a vacuum cleaner.
