Abstract
A cleaner includes a cleaner main body, and a suction unit connected to the cleaner main body to suck air containing dust, and provided with a brush assembly brought into contact with a floor, wherein the brush assembly includes a rotating rod rotatable in one direction, a brush portion protruding from an outer circumferential surface of the rotating rod to rotate together with the rotating rod, and a blade erected at the rear of the brush portion in the one direction to be adjacent to the brush portion, and brought into contact with the brush portion during the rotation in the one direction, to prevent foreign substances from getting tangled in the brush portion. This configuration may prevent foreign substances such as hair and the like from being tangled in the brush portion during an operation of the cleaner.
