Did you know that human washing machines exist?

Human washing machines are advanced devices designed to automate the process of washing and massaging a person’s body, much like a traditional washing machine cleans clothes. The Japanese “Human Washing Machine” from the 1970s, developed by Sanyo, combines bathing, scrubbing, and massaging in one unit.
Modern versions have evolved with more features like water jets, bubbles, and even music to enhance relaxation, often used in luxury spas or therapeutic settings.
