An upright-type vacuum cleaner includes a cleaner body 10 having a dust collecting chamber 11 and a motor driving chamber 13, a suction brush 15, and a cyclone dust collecting device 17 removably mounted in the dust collecting chamber. The cyclone dust collecting device includes a cover, first (30) and second (4) cyclone bodies for centrifuging and collecting contaminants entrained in the air, a lower door (50), and an outlet pipe (60). The second cyclone body includes a grille having a plurality of perforations formed therein to filter out small particle contaminants. The lower door is removably mounted on a lower end of the first cyclone body, and the outlet pipe discharges the clean air. The cyclone dust collecting device 17 prevents a back flow of contaminants thereby collecting contaminants more effectively. A further invention is disclosed of an upright type vacuum cleaner having a cyclone dust collecting device removably mounted in the dust collecting chamber 18, whereby a dust collecting receptacle (90) is removably disposed in the cyclone body.
