1. A multi dust-collecting apparatus comprising:
- a first dust-collector having a bottom connected with an air suction pipe through which an external air is drawn in, the first dust-collector separateing dirt particles from the air drawn in through the air suction pipe using an gravity and an inertia and collecting the separated dirt particles therein;
a second dust-collector arranged around the first dust-collector to centrifugally separate minute dirt particles from the air drawn in from the first dust-collector and collect the separated minute dirt particles therein; and
a cover unit disposed above the first and the second dust-collectors to guide the air discharged from the first dust-collector toward the second dust-collector and discharge the air discharged from the second dust-collector to the outside, wherein the first dust-collector comprises;
a cylindrical first dust-collecting receptacle having a first inlet connected with the air suction pipe and a first outlet to discharge the air, the first dust-collecting receptacle collecting therein the dirt particles separated from the air; and
an air guide member disposed inside the first dust-collecting receptacle and guiding the air drawn in through the first inlet in the direction of an inside surface of the first dust-collecting receptacle such that the dirt particles are separated from the air by the gravity and the inertia.

Abstract
A multi dust-collecting apparatus for a vacuum cleaner is provided. The apparatus includes a dust-collecting unit having an air guide member to separate dirt particles from drawn-in air by using a gravity and an inertia and a filter member to remove dirt particles from the discharged air. The apparatus also includes a plurality of cyclones to swirl the air discharged from the dust-collecting unit and separate minute dirt particles from the air by using a centrifugal force.
