Human laundry

Ultrasonic Bath: Human washing machine

At the 1970 World Expo in Osaka, consumer electronics maker Sanyo demonstrated their vision for the future by showcasing a series of appliances they thought would populate the home of tomorrow. Included was the Ultrasonic Bath, a pod-like human washing machine that cleans, massages and dries the user in a fully automated 15-minute process.

Of course, everyone knows that you're not fully clean unless you're "Zest-fully" clean.
