Existing dishwashers use a rotary system in which the water nozzles rotate 360 degrees and sprays water upward. This dishwasher features WaterWall spray jets—a stationary “wall” of nozzles and a moving bar that deflects those jets upward. As the bar moves along its track, it creates a wall of water that travels back and forth, ensuring that every portion of the tub gets washed effectively. The result is a cleaner and quicker washing of dishes and kitchen utensils.
