PURPOSE: A robot cleaner is provided to prevent noise caused by abnormal contact of a blade and the floor while driving and to maintain driving and cleaning performance by preventing blade twist. CONSTITUTION: A robot cleaner comprises a body, a brush unit, and a blade assembly(82). The brush unit is rotatably formed in an opening part of the body. The blade assembly guides the inflow of dust caused by the brush unit. The blade assembly comprises a blade(83) and a supporting member(85). The blade comprises a first part fixed in the body and a second part extended from the first part toward the floor. In order to restrict flow of the second part of the blade to a predetermined arrangement, at least a part of the supporting member is adjacently arranged to the second part of the blade.
