A vacuum cleaner includes a container having an inlet for dirty air, an outlet for clean air, a coarse dust chamber and a fine dust chamber. The coarse dust chamber includes a filtering tube disposed within a rotary cylinder. The fine dust chamber includes a rotary cone. Air containing dust is drawn into the coarse dust chamber and supplied into the gap between the cylinder's inner surface and the filtering tube's outer surface. The air is rotated within the coarse dust chamber to force coarse dust to travel away from the chamber's center and air containing only fine dust travels through the filtering tube. This air is supplied into the rotary cone within the fine dust chamber and is rotated to force fine dust away from the chamber's center. Dust free air, which is travelling in the center of the rotary cone, is supplied out of the filter as clean air.
