Abstract
A vacuum cleaner includes a cyclone dust separating unit which includes a cyclone part to separate dust from a dust-laden air drawn from a surface being cleaned using a centrifugal force, a dust collecting part comprising a dust chamber to accommodate the dust separated at the cyclone part, and a compressing part to compress the dust accommodated in the dust chamber. The compressing part includes a driving part to rotatably drive a driving axis, and a compressing plate driven in a substantially perpendicular direction with respect to the driving axis according to the rotation of the driving axis, and to compress the dust accommodated in the dust chamber. As a result, a vacuum cleaner is provided, which requires a minimum space for the installation of a compressing part to compress dust inside the dust collecting part, and provides maximum compressing force of the compressing part.
