Performance of older FLs
Tom, At the time that tumbler washers were really in competition with top loaders, the low or controlled suds detergents were not as effective at cleaning as were the high sudsers. Another thing was that, unlike Jeff's machine which is the larger double load machine, most of the tumbler drums were small and did not allow for much tumbling room. Jeff's machine uses the drum from the Duomatic. When Consumer Reports tested the first Bendix Duomatic in the big laundry report of 1954, I think, the Duomatic earned a place just below the highly rated WP agitator washer for washing performance. They said at that time, and again when they tested combos in the early 60s, that the larger drums of the combos gave better washing performance than front loading washers with smaller drums. It is possible that if the Bendix & Philco Bendix washers had used two different pressure switches, one to give a lower water level in the wash and a higher water level in the rinse, the washing ability might have been improved because a shallower pool of wash water would have given more tumble room for the clothes and, at the same time, deprived the sudsing process of the deeper pool of water that created suds every time a tub vane slapped into the pool. The new front loaders that carry most of the wash water within the clothes as they tumble show that this works.
