Abstract: A robot cleaner includes a cleaner body, a suction unit, and a cyclone unit. The cyclone unit has a first suction opening and a second suction opening for sucking air, and a first cyclone and a second cyclone for passing air therethrough, the air having dust filtered therefrom by a centrifugal force. A first guiding member and a second guiding member extend upwardly from the suction unit toward the cyclone unit with an inclination angle, the first guiding member for connection between the suction unit and the first suction opening, and the second guiding member for connection between the suction unit and the second suction opening. A dust box communicated with a dust discharge opening is provided at a front side of the cyclone unit so as to collect dust filtered by the cyclone unit. The dust box is partially or wholly accommodated between the first and second guiding members.

Abstract: A robot cleaner configured to elastically deform a brush part using contact force between bristles and a floor and then restoring the brush part to vibrate the bristles, thereby improving cleaning performance. The robot cleaner includes a case that moves on a floor, a brush shaft mounted to the case such that the brush shaft rotates by driving force from a drive unit, an elastic member fixed to the brush shaft, the elastic member made of an elastic material, and a brush part fixed to the elastic member, the brush part having bristles, wherein the brush part generates generate vibration during deformation and restoration of the elastic member when external force is applied. The elastic member deforms due to contact force between the bristles and the floor and is then restored, and the brush part vibrates during deformation and restoration of the elastic member.
