摘要： A cleaning liquid dispensing system for use in a mobile hard floor surface cleaner includes fluid conduit and fluid communication with a supply of cleaning liquid, a pump, and a flow restriction member. The pump is adapted to drive a flow of the cleaning liquid through the conduit. The flow restriction member generates a pressure drop in the conduit, thereby restricting the flow of the cleaning liquid therethrough.

摘要： A method of cleaning a hard floor surface with a surface maintenance vehicle including the steps of generating a foam-like aerated cleaning liquid, selectively conveying the foam-like aerated cleaning liquid to the hard floor surface and a scrubbing medium operatively coupled to the surface maintenance vehicle, scrubbing the hard floor surface with said rotating scrubbing medium and said foam-like aerated cleaning liquid so as to loosen soil from the hard floor surface leaving behind a soiled solution of cleaning liquid and soil, and removing at least a portion of the soiled solution from the hard floor surface through a fluid recovery device. Additional aspects of the present invention include devices for performing the cleaning method.
