The duster rotating controller of a suction hole having a duster of a vacuum cleaner includes an operating piece movably installed to one side of the body of the suction hole rotating according to the shifting direction of the suction hole and simultaneously by being in contact with the floor; and a power saving device for cutting off a power supply to a motor by rotating with the operating piece, thereby rotating the duster only when the suction hole goes forward.
