By simply lying down in a 2.3-meter-long capsule, the bather is washed by the machine with microbubbles and a fine mist shower, with the whole process, including drying, completed in about 15 minutes. Sensors monitor a bather's health during use, while the machine provides relaxing visuals and music. More than 40,000 applications were submitted for the bathing experience at the expo, which ended in October.
