摘要： 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.

摘要： A robot cleaner includes a cleaner main body that autonomously travels, a suction nozzle mounted to be able to move up and down or swing with respect to the cleaner main body, and a supporter to support the suction nozzle to be able to move up and down or swing. According to this configuration, the robot cleaner can easily respond to a change in a height of a floor to improve travel performance and implement an action that can help in climbing obstacles. In addition, even when a height difference of the floor is large, cleaning performance can be improved by maintaining a contact stress and increasing a suction pressure of the suction nozzle.

摘要： The present invention relates to a robot cleaner comprising a shielding module provided under a cleaner body, wherein the shielding module includes a cam and a hiding plate which rotate with the same phase angle about a same rotating shaft. The distance between the center of the hiding plate and the center of the rotating shaft is configured to be longer than the distance between a contact point on an inclined surface of the cam and the center of the rotating shaft, wherein a guide protrusion of a bumper is in contact with the inclined surface at the contact point. Therefore, the rotation movement speed of the hiding plate which rotates to hide a cliff sensor is much faster than the inner movement speed of the bumper. Accordingly, the present invention can improve sensitivity to the detection of a collision between the bumper and an obstacle by using the cliff sensor.
