ABSTRACT:
A multi dust-collecting apparatus for a vacuum cleaner separating dirt particles from air by taking two steps. The multi dust-collecting apparatus includes a dust-collecting unit to separate dirt particles from the air by using gravity and inertia, and a plurality of cyclones to swirl the air discharged from the dust-collecting unit and separate the dirt particles from the air by using centrifugal force.
