The Typhoon® is a totally automatic wash system. Squeeze the trigger on the built-in pressure washer and the system starts - let go, and the system shuts itself down. A powerful 2600 PSI, 3.6 G.P.M. pressure washer makes cleaning quick and efficient. The spring loaded ramp floats up to give 360 degree enclosure and the heated cabinet allows the Typhoon® wash system to be placed outdoors year round.
