For various reasons post WWII some housewives clung to semi-automatic washing machines well into 1960's. Some did this out of necessity (issues with hot water supply, indoor plumbing, personal preference...) and so forth so they clung to wringer washers. Suds saving automatic washers were a sales/marketing answer to that situation in hopes of countering various objections Her Indoors may have had against fully automatic washing machine.
Never a huge part of market as affluence grew post WWII many couldn't get over the "ewwww" factor of reusing wash water. That was something their mothers or grandmothers did and seemed antediluvian to many modern housewives.
As with a wringer washer using a suds saver required a housewife or whoever to put a bit more planning into order of laundry work. Something not universally welcomed and could be avoided by not reusing water.
Many consumer groups didn't see point of suds saving washers either. Aside from ick factor of reusing "dirty" water they pointed out whatever hot water was stored waiting to be used again likely cooled considerably.
Post war housing boom saw huge numbers of modern homes built designed for "modern living" as it were. More often than not large sinks or built in tubs once used to wash/rise laundry by hand, soak or just drain water were replaced by standpipe drains. One could purchase portable tubs from Sears among others, many designed to accommodate suds saving washers, but that was another expense on top of machine itself.
Newer hones were more likely connected to public sewer systems replacing septic systems. This helped solved worries about water use that suds savers helped solve. This or more and more local areas were connecting existing homes/streets to public sewer system with same results.
Indeed well into 1980's areas of country were homes still largely were on septic systems were likely to be same still using wringer washers or maybe a suds saving automatic. During that decade there was renewed interest in suds saving washers in some quarters as way to reduce energy and water use on wash day.
Like wringer washers and other semi-automatic machines AW seems to have these lively discussions on suds saving washer pretty often. It's always fun to hear from those who were there and their experiences. Our sainted mother dear wouldn't have anything to do with reusing wash water. *LOL* Thus such a machine stood nil chance of getting past front door.

The tub full of hot wash water in this picture is probably made by Mustee. I have a newer one and the tub inside the metal cabinet is made of some type of soft plastic. If I have to wash anything large and delicate like a glass dome or a control panel, I put folded towels in the bottom of the...
