Abstract
An upright type vacuum cleaner has a cleaner body having a vacuum generating apparatus disposed therein and a suction brush disposed at a lowerportion; a cyclone unit for separating contaminants from contaminant-laden air and discharging a contaminant-free air through an outflow passage interconnected with the vacuum generating apparatus, the contaminant-laden air being drawn in through an inflow passage interconnected with the suction brush; a dust receptacle removably connected to an underside of the cyclone unit for collecting the contaminants separated by the cyclone unit; a longitudinally movable locking unit for connecting to and separating the dust receptacle from a lower portion of the cyclone unit by longitudinally moving the dust receptacle upward and downward; and a means for preventing an incorrect connection of the dust receptacle to the lower side of the cyclone unit.
