A robot confinement system includes a portable housing and a mobile robot. The portable housing includes an emitter operable to emit a first signal when a presence of the robot is detected in a field of detection. The robot includes a controller operable to control a movement path of the robot on a surface and a cleaner operable to clean the surface as the robot moves on the surface. The robot further includes a detector operable to detect the first signal emitted by the portable housing. The controller is operable to change the movement path of the robot in response to detection of the first signal. One of the portable housing and the robot is operable to detect a second signal generated by the other of the portable housing and the robot to detect the presence of the robot in the field of detection.
