ABSTRACT:
A cleaning system and dispenser are disclosed which feature a reservoir for retaining a liquid detergent solution; a chamber for retaining a mass of solid, dissolvable detergent; a measurement device for measuring the concentration of detergent in the liquid detergent solution; and a flow control device for circulating the liquid detergent solution from the reservoir into contact with the solid detergent so as to dissolve a portion of the solid detergent and increase the concentration of detergent in the liquid detergent solution. The circulation of the liquid detergent solution is in response to a signal from the concentration measuring device that the concentration of detergent in the liquid detergent solution has fallen below a predetermined minimum. The dispenser also includes a measurement device for measuring the volume of solution in the reservoir and for adding fresh water to the reservoir when the volume of solution is below a predetermined minimum. The dispenser also includes flow control apparatus for dispensing the solution from the reservoir to a use point.
