Abstract
Disclosed herein is a vacuum cleaner including a brush to rotate and collect foreign materials on the floor, and a grinder to grind the foreign materials collected through the brush. Since the hair-like foreign materials wound around the brush are grinded and cut by the grinders, a cleaning cycle of the brush can be extended.
