A multi-cyclone dust-collecting apparatus (10) comprises a multi-cyclone unit (11) having a first cyclone (20) and a plurality of second cyclones (30). The first cyclone (20) separates relatively large dust particles, whereas the second cyclones (30) separate smaller dust particles. The cyclones (20, 30) are arranged under a top cover (200) mounted on a top portion of the multi-cyclone unit (11). This top cover (200) has a plurality of connection paths (210, fig.6) for guiding air flowing from the first cyclone (20) to the second cyclones (30), and a discharge cover (220, fig.6) forming a discharge path for guiding air flowing out of the second cyclones to the outside. The connection paths (210) and the discharge cover (220) are integrally formed. A dust-collecting unit (20) is mounted to a bottom portion of the multi-cyclone unit (11) and collects dust separated by the first cyclone (20) and the second cyclones (30). |
