Abstract: A robot cleaner including a cleaner main body configured to travel and clean a cleaning area, a sensor case arrangeable on the cleaner main body such that while the sensor case is arranged on the cleaner main body, the sensor case is configured to cover a sensor for detecting an obstacle in the cleaning area, and a sensor collision detector configured to detect an impact applied to the sensor. The sensor collision detector includes a bumper connectable to the sensor case which covers the sensor such that while the bumper is connected to the sensor case, the bumper is moveable and at least a portion of the bumper is arranged along an outer circumference of the sensor, a detecting portion to interact with the bumper to detect a collision of the sensor case, and wherein the bumper and the detecting portion are on a lower side of the sensor.
