A vacuum cleaner is provided in which detachment of a dust collection device and compression of dust may be selectively performed. The vacuum cleaner may include a main body, a dust collection device selectively mounted on the main body, and a dust separation device selectively coupled to the dust collection device by operation of a lever assembly.

Vacuum cleaner

A vacuum cleaner is provided that includes a cleaner body, a multi cyclonic (including a primary cyclone and at least one secondary cyclone), a suction source having a suction source inlet and a suction source outlet, a main filter assembly including a main filter element, a discharge member having an opened upper end coupled to a peripheral edge of a primary airflow outlet and a closed lower end, and a guide rib provided at the primary cyclone for guiding the airflow in a direction tangential to an inner peripheral wall surface of the primary cyclone.

Upright vacuum cleaner

Provided is a cyclonic dust collection unit for conveniently removing a foreign object filtered therein. The cyclonic dust collection unit includes: a first filtering chamber for filtering a first foreign object having a first size using a cyclone airflow; a second filtering chamber for filtering a second foreign object having a second size smaller than the first size of the first foreign object, the second foreign object being contained in the air passed through the first filtering chamber; a foreign object storing chamber for storing the first and/or second foreign object(s) separated through the first and second filtering chambers; a filter disposed in the first filtering chamber, for separating the first foreign object on an outer surface thereof; and a cutaway hole formed in a longitudinal direction thereof.

Cyclonic dust collection unit and filter structure thereof

A vacuum cleaner is provided. The vacuum cleaner includes suction means that provides suction force, a suction nozzle that uses the suction force provided by the suction means to draw in particle laden air, a dust collecting box that receives the particle laden air drawn in through the suction nozzle, an upper cover having an opening at a central portion thereof that provides for selective opening/closing of an upper portion of the dust collecting box, and a filter assembly that is selectively fastened to an edge of the opening, for filtering dust from the particle laden air and discharging the air upward. This structure simplifies cleaning and replacement of the dust collector assembly.
