How Does a Top Loading Washing Machine Without an Agitator Work?

If you plan to buy a high-efficiency, top-loading washing machine, start thinking about doing laundry in a new way. Like front-loading machines, these washers do not use an agitator to clean your clothes, saving water and energy but requiring a few changes in routine.

Top-loading, high-efficiency washers do the job without an agitator, but they need special handling.

How They Work

In a traditional washing machine, an agitator twists and turns laundry in a tub full of water to get it clean. Top-loading, high-efficiency washers replace the agitator with wheels, discs or plates that cause the tub to spin or juggle the clothes gently at high speed in much less water. Some also spray the laundry with wash water or a rinse solution to boost the cleaning action. The fast washing speed also pulls more water out of the clothes, reducing time needed in the dryer and further cutting energy use.

Detergent

High-efficiency washers require detergent created for that type of machine. Do not use regular detergent, which causes excess suds that can reduce cleaning power or even make the machine overflow. High-efficiency detergents work especially well in small amounts of water, which is important, because high-efficiency washers use as little as a fifth of the water of traditional machines. Read the owner's manual and directions on the detergent container to determine how much to use and whether to use a dispenser.

Additives

If you want to use water-softening, stain-removal or fabric-softening solutions, read all directions to ensure you use the correct amounts in the right way. Fabric softeners normally go in a dispenser in the machine, but use only rinse-added softeners. Regular pre-treating or soaking solutions often cause too many suds, so consider using your high-efficiency detergent to soak items instead. Add bleach and water softener following machine and package directions, but never mix liquids and powders, which can clog dispensers and reduce effectiveness.

Extra Advice

Watch for wrinkling or bunching of clothes inside a top-leading, high-efficiency machine. The machines also typically cost more than traditional machines, although you will save in reduced use of water of energy, "Consumer Reports" notes. Greasy or oily soils in your laundry may collect inside the washer, especially if you use cool or cold water. Follow directions to run weekly or monthly maintenance cycles without any laundry inside to prevent buildup and odors.
