Dilute & dispense cleaning products easily & efficiently. With space for up to four ExpressMix cleaning-solution concentrates (sold separately), this self-contained, closed-loop system safely minimizes exposure to potentially dangerous chemicals. Two dials allow you to select one of the four solutions for either spray-bottle surface cleaning or floor cleaning. Once you have your selection dialed in, hit the corresponding bright orange start button, & the dispenser automatically dispenses an accurate dilution to your chosen container. Two output hoses, one for each section, conveniently accommodate empty bottles, floor scrubbers, mobile carpet extractors & mop buckets. Includes a mounting template & bracket, as well as all required hoses, to keep installation as easy as possible. Access to a water-line with a pressure range of 25 PSI to 85 PSI is required for operation.
