Agitators and impellers are both found in top-loading washing machines, but they move — and clean clothes — in two distinct ways.
Traditional agitators are tall spindles, vaned or finned, in the center of the wash basket that twist (or agitate) back and forth, rubbing against clothes to help break down loose soils. Impellers, on the other hand, are low-profile cones or discs that spin/rotate to rub clothes against each other to get them clean.
So which style will help you keep laundry day moving? Learn more about the difference between washers with agitators and washers with impellers — and how they make all the difference in the way you care.
Watch how agitators and impellers care for your clothes to help choose which style is right for your family.
A washing machine with an agitator is probably the style you’re most familiar with. Despite what some people think, advances in washer technology ensure that agitators can take on your toughest loads — without being tough on your clothes.
That job belongs to your family. And between home-run mud stains, early-morning coffee spills and tough gym sessions, these appliances have their work cut out for them. That’s why they typically provide multiple wash motions for a good clean, including:
Soaks clothes with water recirculated from the wash/rinse cycle.
Rotates for a hard-hitting clean.
Rubs against clothes to help break down stains and loosen soils.
A washing machine with an impeller uses less motion and water than a washer with an agitator. Designed so laundry has more room to move, it drives clothes from the outer rim of the wash basket to the center, using a small amount of water to optimize the friction. This is what helps deliver a gentle, efficient, yet thorough clean.
They also typically feature multiple wash motions, including:
Soaks clothes with water recirculated from the wash/rinse cycle.
Rotates for a deep clean.
Uses low-profile cones, wheels, fins or discs that spin to gently rub clothes against each other.
Both washing machines with agitators and impellers function optimally when they’re properly loaded. For both, make sure the clothes are placed evenly around the central spindle or wash plate so the wash basket is balanced. Unbalanced loads aren’t cleaned as effectively or can damage the machine.
So which one’s got the right moves for your family: a washer with or without an agitator? Whether you’re sanitizing baby clothes, cleaning mustard out of your favorite jeans or making sure her leotard is ready for ballet class tomorrow, both an agitator or impeller model can help you get the job done. With cleaning performance, energy efficiency, capacity, innovation and convenience being roughly equal, your decision really hinges on your personal preference.
