Sanyo's Human Washing Machine From 1970

Back in 1970, Sanyo envisioned a future where manual bathing was obsolete and head-washing was (apparently) optional. At the World Expo in Osaka, Sanyo unveiled their plan in the form of the Ultrasonic Bath.

Essentially, the device was a human washing machine that cleaned, massaged and dried the occupant in a fully-automated 15 minute cycle.
