Zusammenfassung:	A grill assembly (100) provided in the upper part of the air discharging passage of a cyclone module (20), includes a module (110) and several passages (121) to separate filth from a whirling air current by a centrifugal force and prevent the filth from entering the vacuum generator. An extended unit of the center line of the passage forms an acute angle with a stream line of the whirling air current.
