Turn any garden hose into a powerful cleaning-solution dispenser. Pistol-grip nozzle gun allows you to dilute and spray foamed cleaning products on locker-room floors, shower stalls, window exteriors, building siding, sidewalks, concrete pads and more. Simply fill the included jar-style reservoir-bottle with the concentrate of your choice, screw it into the foamer's reservoir-intake fitting and hook up a standard 0.63" garden hose to the pistol-grip's base. Two turn screws allow you to set your approximate dilution ratio. Common pistol-grip lever allows you to tailor the output pressure to your purpose. Foaming attachment is affixed to the central brass fitting with a pair of spring clips, making it easy to remove for either non-foaming applications or general maintenance.
