Abstract
Abstract A multi-cyclone dust collecting apparatus with improved dust collecting efficiency and suction force is provided. The multi-cyclone dust collecting apparatus includes a first and a second multi-cyclone units having a first cyclone which collects large particles of dust and a second cyclone for collecting fine particles of dust; an air inlet through which an air inlet through which dust-laden air is separated and flowed into the first and the second multi-cyclone units, respectively; and an air outlet through which air from the second cyclone of the first and the second multi-cyclone units is gathered and externally discharged. Because air is branched off once it is drawn into a single gate and dust is separated from the drawn air simultaneously in the plurality of multi-cyclone dust collecting apparatuses, reduction of flow speed in the dust-laden air from the suction brush can be prevented.
