The present invention relates to a robot cleaner whose suction hole can be moved by a relative movement of a guider for forming a suction hole and a suction cover. According to the present invention, the robot cleaner comprises: a case moving along the ground surface; a guider installed on the case to guide the external air into the case through a guide hole formed inside; a suction cover with a suction slit, which is connected to a part of the guide hole to form a suction hole, which is relatively moved with the guide to move the suction hole following the suction slit; and, a cover driving module for providing a driving force to one or more from among the suction cover and the guider to generate a relative movement and move the suction hole. According to the present invention, the robot cleaner has the suction hole formed by overlapping the guide hole and the suction slit, and can form a great negative pressure compared with the motor capacity of the suction module and move the suction hole following the suction slit. |
