Abstract (en)
A vacuum cleaner (10) includes an electric blower (24) that sucks dust through a suction connecting port, a first dust separating unit (55) for separating the dust and air sucked into the suction connecting port from each other, and a pleat filter (104) for separating the dust and air passing through the first dust separating unit (55). The vacuum cleaner (10) further includes an external-air introducing air passage (650) for introducing external air toward an upstream side of the pleat filter (104), a rotational fan (800) for dropping off dust adhering to the pleat filter (104) by the introduced external air, and a return air passage (640) for returning the dust dropped off from the rotating fan (800) toward the upstream side of the first dust separating unit (55) by the introduced external air.
