ABSTRACT:
The multi-cyclone dust separating apparatus includes a first cyclone unit including a first outer tub with a first air inlet and a cylindrical element with a first air outlet, and whirling air from the first air inlet to separate dust therefrom, the cylindrical element being disposed in the first outer tub to form a first cyclone chamber, along with the first outer tub; a second cyclone unit including a plurality of cyclones, each having a second air inlet for drawing in dust-laden air from the first cyclone chamber, to provide a second dust separation; and a dust bin including a first dust collecting chamber for collecting the dust separated by the first cyclone unit and a plurality of second dust collecting chambers for collecting the dust separated by the second cyclone unit.
