Abstract
A hard surface cleaner includes a motorized scrub head, a fluid recovery device, a primary cleaning liquid component container, a cleaning agent container, a flow control device and a fluid flow path. The flow control device is configured to supply a flow of cleaning agent from the cleaning agent container at a flow rate of less than approximately 10 cubic centimeters per minute to a flow of primary cleaning liquid component from the primary cleaning liquid component container. The fluid flow path is configured to receive a flow of cleaning liquid, which comprises the cleaning agent and the primary cleaning liquid component. A method of dispensing a chemical for use in a mobile hard surface cleaner includes driving a flow of cleaning agent from a cleaning agent container at a flow rate of less than approximately 10 cubic centimeters per minute, supplying a flow of primary cleaning liquid component from a cleaning liquid component container supported by the hard floor surface cleaner, combining the flow of cleaning agent and the flow of primary cleaning liquid component to form a flow of cleaning liquid, and dispensing the flow of cleaning liquid to either a motorized scrub head or a surface under the hard floor surface cleaner.
