The Ray Padula 8-Pattern Spray-N-Wash hose nozzle is a great choice for both watering and outdoor cleaning. A unique design features a soap canister designed to automatically add the right amount of soap into the watering stream - an effortless way to apply just the right amount of cleaning material before scrubbing. Once cleaning is finished, simply turn the green control knob to "water" and only fresh water flows through the nozzle for easy rinsing. A patent-pending design features Ray Padula Thumb Control - eliminating the need to squeeze a trigger, or push a button. Best of all, with one simple motion of your thumb, the nozzle can be turned ON, OFF, or anywhere inbetween. Also works with water soluable fertilizers.
