Surface-cleaning device

摘要

A device for cleaning a surface, such as a barbeque grill, has a substantially hollow enclosure that has at least a lower side, an upper side, and a peripheral edge, and contains a plurality of motors that each has 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 enclosure further contains a power source and a circuit adapted for connecting power 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.

1. A device for cleaning a surface of a grill, comprising:
a substantially hollow enclosure having at least a lower side, an upper side, and a peripheral edge; a plurality of motors each contained within the enclosure, each motor of the plurality of motors having a rotational shaft fixed with a rotatable brush, each rotatable brush is oriented at a substantially same angle greater than zero degrees from each adjacent brush such that each rotatable brush is configured to move in a direction different from any other rotatable brush, each rotatable brush having a plurality of bristles radially projecting from a rotational axis thereof, at least a portion of the bristles of each brush projecting below a plane of the lower side of the enclosure, the plurality of bristles including metal capable of withstanding heat emanating from the surface of the grill for cleaning the surface of the grill after the grill has just been used, wherein the brushes simultaneously serve as the cleaning and motive force for the device when the brushes are rotated by the motors; a power source; and a circuit adapted for connecting power from the power source to each of the motors for a preset period of time upon actuation of an electrical switch connected thereto, the circuit adapted to run each motor of the plurality of motors in a first direction and then an opposing direction, respectively; whereby with the enclosure placed upon the surface of the grill and the switch actuated, the circuit runs each motor in the first direction and then alternately in the opposing direction, such that the brushes simultaneously support and move the device along the surface of the grill and clean the surface of the grill, the enclosure if becoming stuck at an obstruction eventually turning around due to the alternating directions of the motors.
