Above, we see two renderings of circa-1948 automatic (sans wringer) washers. The Frigidaire Fully Automatic model, seen in the first rendering, came with the hefty price of $329.75! In today's money, this washer would cost over $3,700! The price of General Electric's All Automatic machine is not divulged in the advert.

A full page ad, dated June 6, 1949, hailing the new Bendix Economat machine. Its thrifty price -of just $179.95- must have made it a hot-selling item!
