Abstract
A multi cyclone dust-separating apparatus is disclosed that includes a cyclone unit having a first cyclone, a plurality of second cyclones, and a dust collecting unit. The first cyclone is disposed so that a longitudinal axis thereof is substantially vertically arranged. The first cyclone separates relatively large dust or dirt from air drawn in through a first air inflow part. Each of the second cyclones is disposed so that longitudinal axes thereof are substantially vertically arranged. Each of the second cyclones has a second air inflow part to communicate with the first cyclone and an air discharging part to discharge the air. The second cyclones separate relatively minute dust or dirt from the air drawn in through the second air inflow part. The dust collecting unit is disposed below the cyclone unit to collect and store the dust or dirt separated from the air by the cyclone unit.
