ABSTRACT:
A vacuum cleaner includes a main body having an electric blower for generating a suction air flow, a dirt collecting case for centrifugally separating and collecting dirt, and a compression assembly for compressing dirt collected in the dirt collecting case to reduce a volume thereof. The dirt collecting case has a separation chamber for centrifugally separating dirt from the dirt containing air and a dirt collecting chamber in communication with the separation chamber for accumulating the dirt separated by the separation chamber. The compression assembly has a first air intake member provided in the separation chamber and communicating with the electric blower, a second air intake member provided in the dirt collecting chamber and communicating with the electric blower, a shielding plate for selectively opening the first and the second air intake member and an actuator for driving the shielding plate.
