ABSTRACT:
A cyclone dust-collecting apparatus comprises an upper casing having an air suction port formed thereon, a lower casing connected to the upper casing to form a cyclone chamber, a guide unit disposed between the upper and the lower casing, and having a first channel for swirling a dirt-laden air drawn in through the air suction port, and a second channel for discharging a cleaned air therethrough; and a filter assembly mounted between the guide unit and the lower casing, for removing a dirt and a dust from the air as drawn in. Accordingly, a compact-sized cyclone dust-collecting apparatus is realized and maintenance management of the vacuum cleaner becomes easy.
