Other than a limited lifespan, the front loading Westinghouse washers cleaned well with warm and hot water and a good low sudsing detergent and the spin speed of 500rpm was not terribly much slower than than many other machines. It was a bonus, as one ad for them said, that you save so much in water and detergent that you can buy a new one every 5 years, which came close to the washer's lifespan with moderately heavy use. It's funny that after decades of the testing magazines putting tumbler washers down, they are now the sane high efficiency choice in this country, following most of the rest of the world which was trying to save scarce resources long before we were concerned with the issue. Once Westinghouse got rid of the tilted tub and the tangling it caused, the machines were pretty satisfactory as most of us who have had them have found. I knew a family with 3 little boys who had to get one of the original sets of Space Mates because that was all they had room for and the mother loved the performance so much that when they wore out, she got a pair of the early 60s slant fronts. It would be a few years after these 1958 models that the design would change to the two baffle, non-tilted tub, but that started the grudging average rating in washing ability that the testing magazines had to award them. As for water extraction, our GE dryer did not have to run super hot to dry loads in regular times. If it were not for the apartment and condo designers needing a stack washer and dryer measuring 27" wide, and the replacement market that created, and the power companies that sold them, these machines would probably have died out. It's funny how like with other things, once models from Europe were introduced in the high end markets, the Askos and Mieles, other consumers started exploring the idea of these tumbler machines and found them satisfactory, too.
