A brush assembly for a vacuum cleaner includes a brush body having a suction inlet; a main brush which is rotatably coupled to the brush body through the suction inlet to face a surface being cleaned; and a secondary brush which is rotatably mounted on the brush body to rotate between at least two positions including a first position, in which the secondary brush contacts the surface being cleaned, and a second position, in which the secondary brush does not contact the surface being cleaned.
