A vacuum cleaner is provided to minimize the volume of stored dust and maximize a dust collecting capacity of a dust collecting unit by compressing dust with pressing elements. A dust collecting unit has a dust separating part for separating dust from inhaled air. A dust storing part stores the separated dust. Pressing elements(240,250) compress the dust stored in the dust storing part. A driving unit drives the pressing element positioned at an upper side of the dust storing part, and includes a compression motor(220) and a housing(210) coupled with a cover element.
