That would be Speed Queen's new "Energy Saver Cycle" available on their commercial TL machines. The machine dumbs down wash temps a LOT (When you select hot, it fills halfway with hot water and halfway with warm water kind of thing.), then it does the wash cycle, drains about half of the wash water, fills back up, agitates for another 5-6 minutes, then drains the water away while spraying fresh water on the clothes until the tub is empty. The machine then spins and is done.
Speed Queen markets this cycle as using only 23.7 gallons of water. My Alliance coin-op has rotary controls and has a total of 6 cycles. Normal, Permanent Press, and Delicate with a full wash and rinse like a normal machine and the same three cycles again with the energy saving feature. The use of liquid fabric softener is not recommended...
