A multi-cyclone dust collector (1) for a vacuum cleaner (100) includes a first cyclone unit (10) forcing contaminants-laden air to form an upwardly whirling air current so as to centrifugally separate contaminants from the contaminants-laden air, the first cyclone unit (10) having an air communicating member (40); a second cyclone unit (50) being disposed under the first cyclone unit (10), the second cyclone unit (50) forcing partially cleaned air discharged through the air communicating member (40) to be sucked into a lower portion of the second cyclone unit (50) and to form a second upwardly whirling air current so as to centrifugally separate fine contaminants from the partially cleaned air, the second cyclone unit (50) having a plurality of second cyclones (60); and a contaminants discharging member (90) being disposed over the second cyclone unit (50) inside the air communicating member (40) for discharging the fine contaminants separated in the second cyclone unit (50) to an upper side of the air communicating member (40). |
