Abstract: A dust collector for a vacuum cleaner disclosed herein includes a first cyclone that is configured to separate dust from air introduced from a lower portion thereof with containing foreign materials and discharge the separated dust into a first dust storing unit, a second cyclone that is configured to separate fine dust from the air, from which the dust has been separated by the first cyclone, and discharge the separated fine dust into a second dust storing unit defined in a second case, and a lower cover that is coupled to the first case by a hinge so as to define a bottom surface of the first dust storing unit, the second dust storing unit and the first cyclone upon being closed, and discharge therethrough the foreign materials collected in the first dust storing unit, the second dust storing unit and the first cyclone upon being open.

Abstract: A dust collector for a vacuum cleaner disclosed herein includes a first cyclone to primarily separate dust from air introduced from a lower portion thereof with containing foreign materials and discharge the separated dust into the first dust storing unit, a second cyclone extending in an intersecting direction with an extending direction of the first cyclone and configured to secondarily separate fine dust from the air introduced from the first cyclone and discharge the separated fine dust into a second dust storing unit, and a lower cover defining a bottom surface of the first dust storing unit, the second dust storing unit and the first cyclone and coupled to the first dust storing unit by a hinge such that the foreign materials collected in the first dust storing unit, the second dust storing unit and the first cyclone are discharged upon being open.

Abstract: Provided is a vacuum cleaner. The vacuum cleaner includes a cleaner body and a dust container separably mounted on the cleaner body. The dust container includes a dust collection body including a first chamber in which air and dust are separated from each other and a second chamber in which the dust separated in the first chamber are stored and a pressing member rotatably reciprocated between the first and second chambers within the dust collection body to compress the dust stored in the second chamber in one direction while moving from the first chamber to the second chamber.
