<p>A brush assembly comprises a body (110) having a dirt suction port (111) formed thereon, a cover (140) connected with an upper portion of the body to form a suction passage (S1) and a turbine chamber (S2), a turbine (130) mounted in the turbine chamber (S2), and a brush drum (120) being rotated by a rotational force received from the turbine. The turbine chamber and the suction passage are partitioned from each other, and the turbine is rotated by an air drawn in through an air suction port (141a, 142a) which is separated from the dirt suction port. Accordingly, the turbine is prevented from being clogged by dirt, dust or hair.
