An upright type vacuum cleaner includes a cyclone type dust collector to collect contaminants from the air that is drawn in through a suction brush. The cyclone type dust collector includes a cover, first and second cyclone receptacles, and a lower door. The first cyclone receptacle separates by centrifugal force and collects large particle contaminants. The second cyclone receptacle, disposed in the first cyclone receptacle, separates and collects minute dust and includes a grill having a plurality of fine holes, through which air from the first cyclone receptacle flows into the second cyclone receptacle. The lower door provides access to the contaminants collected in the first and second cyclone receptacles. A reverse flow prevention section is also provided to prevent a reverse flow of contaminants from the lower door.
