Abstract
A brush apparatus capable of controlling a drive of a brush member with a simplified structure and a vacuum cleaner having the same. The vacuum cleaner includes a rotatable brush member, a driving unit to drive the brush member, and a blocking unit disposed between the brush member and the driving unit to selectively block a driving force transmitted between the brush member and the driving unit. The driving unit includes a suction motor to generate a suction force, and a single continuous connecting belt connecting the suction motor and the blocking unit.
