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. An agitator is a spindle that sticks up in the center of an automatic washing machine's wash drum. 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.
