Bath time has never been easier -- assuming you don't mind risking a six-foot fall to the bathroom floor.
Unveiled at Expo '70 in Osaka, Japan, 1970, the Sanyo Ultrasonic Bath or the "human washing machine" (that is, a washing machine for humans) took all that low-tech tedium of going at it with soap and loofah and replaced it with state of the art automated ablutions. Just climb into the top of the machine (assuming that you have a twelve-foot high bathroom ceiling), set the temperature, and the machine's ultrasonics gently produced heaps of lather. Soaks, washes, rinses, dries, and massages; the Sanyo Ultrasonic did it all.
The spin cycle was apparently beyond words.
