PURPOSE: A dust suction structure of a robot cleaner is provided to improve cleaning efficiency by sucking dust of a wide range at a time when the cleaner moves while cleaning. CONSTITUTION: In a dust suction structure of a robot cleaner, a dust suction port(101) for sucking dust is formed to the center part of the bottom surface of a cleaner body(1). Several curve-type brushes(102) are installed to the outside of the dust suction port, to collect dust or dirt to the center part. The curve-type brushes are radially installed at intervals of 120 degrees. The curve-type brush comprises a curve-type rod bent at a predetermined angle and fixed, and a pipe body-shaped brush rotatably combined to the outside of the curve-type rod. A lubricant is interposed between the curve-type rod and the pipe body-shaped brush.
