When the user steps up to the CleanTech hand washing machine, and inserts hands into the two wash cylinders, the 12-second wash-sanitize-rinse cycle automatically starts. The rotating cylinders â€” with high-pressure, low-volume jets â€” spray water and mix in a proprietary soap formulation. The 20 spray jets in each cylinder are placed in a spiral configuration to clean fingertips, hands, wrists, and under fingernails. The 12-second cycle performs a precisely measured and controlled pre-rinse, wash and post-rinse. The user leaves their hands in the system until the cycle stops, then immediately dries their hands using a no-touch paper towel dispenser or a no-touch air dryer.
