Surface-cleaning device
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 one or more motors having one or more rotational shafts selectively fixable with one or more rotatable brushes. The one or more rotatable brushes have a plurality of bristles. At least a portion of bristles 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 the one or more motors for a preset period of time upon actuation of an electrical switch connected thereto. The circuit is adapted to run the one or more motors in a first direction and then an opposing direction, such that if the device becomes stuck at an obstruction, it will eventually turn around due to the alternating directions of the one or more motors.
