A device for cleaning a surface (e.g., a barbeque grill, etc.) generally includes an enclosure having at least a lower side, an upper side, and a peripheral edge. The device includes a plurality of motors each having a rotational shaft selectively fixable with a rotatable brush. At least a portion of bristles of each brush projects below a plane of the lower side of the enclosure. The device also includes a circuit adapted for connecting power from a power source to each of the motors for a preset period of time upon actuation of an electrical switch connected thereto. The circuit is adapted to run each motor in a first direction and then an opposing direction, such that if the device becomes stuck at an obstruction, it will eventually turns around due to the alternating directions of the motors. |
