Dishwasher Variable Pressure Jets
Variable pressure jets use a variable speed motor to vary water pressure throughout the wash cycle. Having different water pressure variation allows the jets to hit different points in the dishwasher at different pressures, therefore maximizing water coverage
Also, different types of soils respond better to different water pressures. For example, a piece of dried-on oatmeal might benefit from high water pressure that helps "flick" the soil off. Maple syrup, on the other hand, just spreads out with high pressure. This type of soil benefits more from a lower water pressure with more flow to help dissolve the soil.
