PURPOSE: A robot cleaner is provided to effectively clean an uneven surface by increasing the negative pressure of a suction port through a narrow area of suction tubes and finely distribute the negative pressure to the surface. CONSTITUTION: A robot cleaner comprises a suction port(4) formed at the bottom of a robot cleaner body to draw in dust and debris from a surface to the inner collecting area of the robot cleaner body, a suction port guide(2) surrounding the suction port in the form of closed curve and generating negative pressure around the suction port by the operation of a fan installed inside the robot cleaner body, and a tight suction guide(10) detachably coupled to the suction port guide and comprising suction tubes(11) sucking dust and debris into the suction port. |
