The nozzle of the Swash CL2200 extends only during the wash cycle. At all other times, they remain retracted within the unit to avoid contamination or soiling. The nozzle features an automatic hygienic rinse cycle that runs before and after every wash. As a further safeguard, the Swash CL2200 also features Nozzle Clean+, a longer, on-demand nozzle wash for enhanced, hands-free nozzle cleaning.
