| (54) | Dust-collecting device and vacuum cleaner for both wet and dry cleaning using the same | 
| (57) The present invention relates to a dust-collecting device and a vacuum cleaner for
                     both wet and dry cleaning using the dust-collecting device. The dust-collecting device
                     of the present invention comprises a dust-collecting tank (20) for collecting water
                     and foreign substances in a cyclone manner, the dust-collecting tank (20) having a
                     suction port (22) formed such that air flows along an inner peripheral surface of
                     a dust-collecting space (21) defined therein; a tank cover portion for selectively
                     shielding the dust-collecting space, the tank cover portion (40) having a first discharge
                     port (41); a floater guide (50) including an inner space (51) communicating with the
                     first discharge portion (41), a floater (52) for opening or closing the first discharge
                     port (41), and a plurality of communication holes (53) formed along an outer peripheral
                     surface of the floater guide (50); a dust-collecting filter (60) provided to surround
                     the outer peripheral surface of the floater guide (50) in order to filter out foreign
                     substances; and a waterblocking wall (43) for surrounding at least a portion corresponding
                     to the suction port (22) with a gap with respect to an outer peripheral surface of
                     the dust-collecting filter (60). According to the vacuum cleaner using the dust-collecting
                     device according to the present invention constructed as such, there are advantages
                     in that water is prevented from being transferred to parts within a main body (10)
                     of the vacuum cleaner, and the structures of the dust-collecting filter (60) and the
                     like provided within the dust-collecting tank (20) can be more firmly maintained. |
