1. A robot confinement system, comprising:

  • a portable barrier signal transmitting device comprising;

    a first emitter configured to emit a first confinement beam; and

    an input device enabling a user to select an amount of power of the first confinement beam; and

    a mobile robot comprising;

    at least two wheels;

    at least one motor connected to the at least two wheels for moving the mobile robot on a surface;

    a cleaner configured to clean the surface as the mobile robot moves on the surface;

    a detector configured to detect the first confinement beam; and

    a controller configured to control the at least one motor to change a movement path of the mobile robot to prevent the mobile robot from crossing the first confinement beam bydetermining whether the detector detects the first confinement beam, andupon determining that the detector detects the first confinement beam, turning the robot in a chosen direction until the detector no longer detects the first confinement beam.
