I hate to be pushed this far, but you don't know everything. You don't even know that much. Don't give us this crap that hand washing was all that was available a century ago or your oscillating basins. They had the wooden wash wheels in commercial laundries in California going back at least to the beginning of the 20th century, perhaps before that. My parents saw them in old laundries owned by the same families that built them who were friends in the 1940s. I am only responding because I and many others refuse to be bullied by you just because you can type. Launderess stated that tumbler washers have been proven best for a century. You do not know laundry history, at least not in this country.
All of your double talk about the tests on washers by CU in the 1980s report is just that: double talk. By the 80s, detergents had improved and tumbler washer drums had increased in size. Actually the drums increased in size in the Westinghouse by 1960 or so. They gave results on a par with top loading agitator washers. Get over it already. Much as you would like to, you cannot rewrite history based on your beliefs (or on the performance of older European tumbler washers). We have enough people trying to do it in this country so we don't need you doing it from outside.
