For washing ability, capacity, noise, energy and water efficiency, front-loaders generally trump top loaders. However, they can be more expensive to buy, and most also require the use of a special, low-sudsing detergent that can cost more per load than top-loader detergent. Among front-loaders, the Kenmore 4104, $700, is our choice for performance and efficiency. It's expensive compared with many top-loading washers, but the energy and water it saves could pay for its added cost over its lifetime. Three other front-loading washers--the GE Profile WPXH214A and similar Frigidaires--are also reasonably priced. All three share a similar design but have different controls. Among top-loaders, the Kenmore Calypso 2206 and similar Whirlpool Calypso GVW9959K--each $1,250--excel in performance and efficiency. But the Maytag PAV2300A, $370--A CR Best Buy--washes clothes just as well, is reasonably efficient, and costs far less.

If space is at a premium, you may want to stack a full-sized front-loading washer below a dryer with controls in front; the Key Features listing for each washer (which you reach by clicking on the model name in the chart) details which models can be stacked in this way. But there are two other space-saving options, involving types of machine that aren't included in the ratings below but which we've recently tested.

The first option is a laundry center, which combines a full-sized washer and dryer in one unit. All those we've tested are full-sized machines. A relatively low-priced option is the Kenmore (Sears) 9081[2], $950.

Compact stackable units are the smallest option; they're typically about 5-1/2 feet tall, compared with more than 6 feet for the other options. An inexpensive compact pair is the GE Spacemaker WSLS1100A washer, $530, and DSKS433EB dryer, $380. Both performed well in our tests and are relatively quiet.
