Inside Consumer Reports Test Labs: New washer reviews—Estate ETW4400W, Whirlpool Cabrio WTW6500W, Whirlpool Duet Sport WFW8400T

Our latest ongoing tests of washing machines included three very different washers yet they had two things in common: All are made by Whirlpool and, more notable, they were tough on our test loads. See our newly updated ratings (available to subscribers) for more details on these and dozens of other top- and front-loading models and use our free buyer's guide to washing machines for more expert advice.

The Estate ETW4400W[Q] top-loader, $330 (right in the photo), merited the lowest gentleness score of these machines—a poor—causing fabrics to fray. The Estate's overall washing performance was very good—impressive considering that most conventional top-loaders we see tend to be mediocre at washing. Cycle time was 48 minutes, comparable to other top-loaders with agitators. And while this machine offers very good capacity—it has a claimed capacity of 3.2 cubic feet in its porcelain wash basket—it was only good in our energy- and water-efficiency tests.

We also tested the Whirlpool Cabrio WTW6500W[W], $750 (left in the photo), a high-efficiency top-loader with Energy Star qualification. It lacks a center-post agitator and its cycle time of 62 minutes isn't unusually long but still managed to cause some wear and tear on the loads we cleaned, scoring only a fair in gentleness. This Whirlpool aced the water-efficiency tests but was just good in the energy-efficiency tests. It has a claimed 5.0-cubic-foot stainless-steel wash basket and provides 14 different automatic cycles.

Front-loaders typically offer superior cleaning performance and efficiency at a price of $750 and up. The Energy Star-qualified Whirlpool Duet Sport WFW8400T[W] delivers top washing performance and water efficiency; at $750, it costs somewhat  less than many other front-loaders. Its claimed 3.7-cubic-foot stainless-steel wash basket holds an impressive 18 pounds of laundry, and its 102-minute cycle time is longer than most, which probably accounted for its fair gentleness score. —Kimberly Janeway | e-mail | Twitter | Forums | Facebook
