Agitator vs. impeller washers
What’s the difference between agitator and impeller washing machines?
Agitators and impellers are both found in top-loading washing machines, but they move — and clean clothes — in two distinct ways.
Agitators in washing machines 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. Impeller washers on the other hand, have 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 can help you provide the best care for your clothes.
How does an agitator in a washing machine work?
Agitators are a central post in a washer that twists back and forth to rub against clothes and help break apart stains.
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 to help you provide a great clean.
How does an impeller washer work?
A washing machine with an impeller uses a low-profile cone, wheel, fin or disc that spins or rotates to gently rub clothes against each other to help loosen stains.
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, yet thorough clean.

Tip to load washers with impellers and agitators
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.
Agitator vs. impeller: which is right for you?
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.
