We've come a long way from the days of a metal tub and a length of rope. The following innovations are now becoming standard issue in the laundry room.

Agitator-free washers. No agitator means less abrasion, so clothes are less apt to fade, fuzz, and pill. Since Americans still prefer top-loaders (those with the door located on the top of the washer), Maytag has come up with the Neptune, the first agitator-free top-loader.

Automatic detergent dispensers. Models that release detergent, bleach, and fabric softener at the right moments are available from Asko, LG, General Electric, Kenmore, and Whirlpool. This feature allows each additive to work effectively without counteracting the performance of the others. (For example, bleach and detergent added at the same time can neutralize each other.)

Automatic sensors that detect load size. Some washers can gauge a load's weight and adjust the water level to conserve energy. Dryers with sensors can judge how much heat is needed for a load, which reduces wear and tear on fabrics. LG, Kenmore, and Miele all have models that offer this feature.
