An upright cyclone vacuum cleaner

An upright-type vacuum cleaner includes a cyclone type dust collector (15) to collect contaminants from the air drawn in through a suction brush. The cyclone-type dust collector includes a cover (20), first and second cyclone receptacles (30, 40), and a lower closure (50). The first cyclone receptacle (30) separates by centrifugal force and collects large particle contaminants. The second cyclone receptacle (40), disposed inside the first cyclone receptacle (30), separates and collects small particles and includes a grille having a plurality of fine holes (41a), through which air from the first cyclone receptacle (30) flows into the second cyclone receptacle (40). The lower closure (50) provides access to the contaminants collected in the first and second cyclone receptacles (30, 40). A reverse flow prevention section (33, 51) is also provided to prevent reverse flow of contaminants from the lower closure (50). A further cleaner is claimed having a cyclone air exhaust pipe that can act as a handle.
