A robotic floor cleaning device comprises a chassis (10), motor-driven wheels (11) supporting the chassis (10), a motor-driven suction fan (9), a dirty air inlet (2) and a motor-driven rotatable agitator (4) at the dirty air inlet (2) for agitating the surface. A control system navigates the device around a room and distributes power to the motor-driven wheels (11) and to the agitator (4). The control system detects when the agitator (4) has jammed (100, 102) and, in the event of a jam, attempts to clear the jam (104, 106). After successfully clearing the jam the control system turns the agitator (4) off (114, 116, 118) or navigates the cleaning device around the location at which the jam occurred (119). The cleaning device can store the location of the jam for use in preventing further jams when the cleaning device returns to a similar position in the room. |
