  • Patent number: 8443478
    Abstract: This invention relates to a mechanism for use in a device that comprises a system for collecting dirt and debris from a variety of floor and upholstery surfaces. In particular the mechanism lifts and directs unwanted debris particles to a waste reservoir for the purpose of cleaning and grooming floor surfaces. The debris collection mechanism can be, but is not limited to its use in a handle operated cordless motorized floor sweeper to collect and gather unwanted debris and dust. The device includes a head unit that incorporates two easily removable elongate cylindrical rotating cleaning bars that are driven such that they contra rotate, and are positioned close to one another at the forward region of the head unit. A removable debris reservoir, removable rechargeable power source and handle incorporating a device operation switch are also included.

  • Publication number: 20130061408
    Abstract: 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.
