Abstract
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.
