TOKYO: After wowing World Expo visitors, a human washing machine is now on sale in Japan, a company spokeswoman said Friday.

Users lie down in the pod, close the lid and get cleaned like clothes in a washing machine — but without the spin — while music plays.

A prototype of the device, called the human washer of the future, attracted long queues at the six-month Expo that wrapped up in Osaka in October after welcoming over 27 million people.

Made by Japanese firm Science, the device is an update of a product displayed the last time Osaka hosted the event, in 1970.

“Our (company) president was inspired by that as a 10-year-old boy at the time,” Science spokeswoman Sachiko Maekura told AFP.
