  • Patent number: 7555812
    Abstract: The brushless vacuum cleaner is an electrical cleaning device that would feature conventional components from traditional upright vacuum cleaners but would use forced air to agitate debris from the surface to be cleaned. The brushless vacuum cleaner would consist of a base unit with multiple air injectors on the bottom, a pump case located on top of the base unit, a collection unit extending upward from the pump case, a vacuum chamber connecting the bottom of the base unit to the collection unit, and a handle that features various control buttons. The pump case would contain an electrical motor which would operate a dual-cycle agitator responsible for pulsing air flow through alternating air injectors on every other cycle. This system would replace the beater brush found on conventional upright vacuum cleaners, thus creating less wear and tear to carpeting and prolonging the life of the carpet.
