Abstract: A robot cleaner and a method for controlling the same are disclosed. The robot cleaner includes a body provided with a suction portion and a slope formed to be inclined at a lower end thereof, an auxiliary front wheel disposed at a rear side of the slope, a main wheel disposed at a rear side of the auxiliary front wheel and arranged such that a height of the main wheel is variable with respect to the body, and a driving unit to lower or raise the main wheel with respect to the body, wherein the driving unit lowers the main wheel when the auxiliary front wheel enters a stepped portion. The robot cleaner is capable of climbing up a higher stepped portion than in conventional cases.

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.
