Abstract: A robot cleaner is disclosed. The robot cleaner includes a main body, a suction device provided inside the main body, a suction port for sucking foreign substances upon operation of the suction device, a dust collection device for collecting foreign substances from air sucked through the suction port, one or more wheels for enabling the main body to travel autonomously, and a control unit for controlling operation of the suction device and the wheels. The main body includes an upper housing and a lower housing, which are coupled to each other, and a side body interposed between the upper housing and the lower housing to surround a side portion of the main body. One or more obstacle sensors are mounted to the side body. One or more sensor covers are removably mounted to the side body at positions corresponding to the one or more obstacle sensors.
