    a driving wheel for enabling the main casing to travel on a cleaning-object surface;

    a control unit for controlling operation of the driving wheels based on detection of an object by the object sensor to thereby make the main casing autonomously travel, whereinwhen an object is detected by the object sensor, the control unit controls the operation of the driving wheels so that the main casing is swung to an angle corresponding to a direction of the detected object to thereby make a side portion of the main casing face the object.
