Abstract
A washing machine having high pressure angled air jets that introduce air into the wash water in a stationary pressurized tub. A circular swirl flow-pattern and air pressure within the warm wash water agitates and cleans the clothes without the need for a mechanically rotated drum or detergent. Sediment from the laundry is removed from the water by drains both at the top and the bottom of the tub. At the end of the wash cycle, the high pressure air is used to drain and dehydrate the clean clothes.
