GE made a spin-drier! Lots of them, but like Westinghouse, I don't think they resumed production of these after the war. Focus on automatic washers, dryers and the like drew the investment away from spinner washers that never really caught on anyway.
Consumer Reports magazine in 1936 (IIRC) did a report on washers and claimed that the wringer washer was inherently unsafe and inefficient and should be avoided by all buyers except those who could afford nothing else. This probably meant little to many during the Great Depression, especially those in rural areas reading by kerosene lamp or candle.
