    Abstract: The present invention provides a cleaning unit, comprising: a columnar body part having a rotation guide opening formed on the outer circumferential surface thereof; a shaft installed to reciprocate a predetermined distance in the longitudinal direction thereof in a hollow formed in the body part; a drive part that protrudes from the shaft in the radial direction thereof; a brush part that has one side installed on the outer circumferential surface of the body part along the longitudinal direction thereof and rotates on the basis of the one side as a rotation axis; and a driven part that extends from the brush part toward the drive part, passes through the rotation guide opening, and is inserted into a rotation guide groove formed in the drive part. The rotation guide groove extends at a predetermined angle with respect to the longitudinal direction of the shaft, and as the shaft reciprocates, the driven part is guided to rotate by means of the rotation guide groove, and the brush is rotated by means of the rotation of the driven part. The cleaning unit may include a robot cleaner or a cleaner operated by means of a user's operation.
