A vacuum cleaner includes a first dirt separation unit and a second dirt separation unit. The first dirt separation unit has a first inlet port through which a suction air stream including dirt particles is introduced thereinto, and the second dirt separation unit has a second inlet port through which the air stream introduced into the first dirt separation unit is introduced into the second dirt separation. The first and the second inlet port are disposed such that they are not registered with each other. Accordingly, the dirt particles suctioned are separated in two stages, thereby decreasing the possibility of occlusion of a filter and rapid deterioration of a suction force.

Vacuum cleaner

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.
