Abstract: A robot cleaner includes a main body that autonomously travels, a suction nozzle configured to move up and down or swing with respect to the main body, and a support to support the suction nozzle. The robot cleaner may respond to a change in a height of a floor to improve travel performance and may respond better to obstacles. Even when a height difference of the floor is large, cleaning performance may be improved by maintaining contact and increasing a suction pressure of the suction nozzle.

Abstract: Disclosed is a cleaning unit comprising a variable brush portion. The cleaning unit according to an embodiment of the present invention comprises a shaft capable of reciprocating along an axial direction, wherein a first cam protrudes from the outer circumferential surface of the shaft. In addition, the brush portion is arranged on the outer circumferential surface of a body member surrounding the shaft, and the brush portion includes a second cam engaged with the first cam. When the shaft is moved in the axial direction, the first cam pushes the second cam in a radial direction, whereby the brush portion may protrude in the radial direction. That is, as the shaft reciprocates in the axial direction, the length of the brush portion protruding from the outer circumferential surface of the body member may vary.
