Agitators and impellers are devices that top-loading washers use to move clothes during the wash cycles and, in the process, get rid of dirt and stains.

The agitator is usually equipped with fins or vanes, and it twists and turns during the machine's wash cycle, moving clothes through the water and, ideally, removing dirt from them.
