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