More than 50 years later, the “Human Washing Machine” is back. This time it is ready to step into our bathrooms and revolutionize the way we wash ourselves!
What is a Human Washing Machine?
Imagine stepping into a machine that senses your stress levels and mood and adapts the washing program accordingly to give you maximum relaxation and spa experience in 15 minutes. In addition, you will be completely clean in the process!
This is the concept for the Human Washing Machine, which first saw the light of day at the Osaka Expo in 1970. Unfortunately, not much came of the project 50 years ago as, among other things, technical challenges stood in the way.
“We aimed for small bubbles, which we thought would remove more dirt, but it was technically difficult,” former Sanyo engineer Eiji Yamaya told The Mainichi Shimbun.
Furthermore, production was somewhat rushed, which led to too many compromises, such as putting too much focus on design instead of function. This led to the effectiveness of both the cleaning bubbles and the ultrasonic waves not having the desired effect. Probably the concept was also a bit ahead of its time and the public was simply not ready to jump into a “Human Washing Machine”.
Although the original company, Sanyo, has been acquired by Panasonic and development started by a completely different company, Science Co, many of the original developers remain as consultants for the project. With the revival in 2025 and the integration with, among other things, AI systems that detect and adapt the settings to the individual, Science Co hopes that the time has come and success is a fact!
Science Co’s “Human Washing Machine”
What is the difference between today’s human washing machine and the 1970 model?
- AI-driven personalization: The machine uses AI to adapt the washing experience to individual needs. Sensors measure, among other things, vital signs and stress levels to optimize water temperature and other settings.
- Vital Sign Monitoring: Sensors in the machine monitor the user’s vital signs, which can help detect any health problems.
- Stress analysis: The machine can analyze the user’s stress levels and create a relaxing environment by adjusting lighting, sound and other factors.
- Ultrafine bubble technology: The machine uses ultrafine bubbles, smaller than 0.001 mm, to effectively and gently clean the skin. This technology is also environmentally friendly as it reduces water consumption.
- Relaxing environment: In addition to washing the body, the machine aims to “wash the mind” by creating a calming experience. It can project soothing images and adjust the atmosphere according to the user’s mood.
In addition to this, the whole process takes about 15 minutes, from the start to the end of the drying process. More precise information and testing will come in April 2025 at the Osaka Kansai Expo, where the machine will be displayed and tested by the public for the first time. After the fair, the company expects to be able to better adapt the washing machine to home use in order to reach a wider audience.
The impact of the human washing machine
Imagine a future where your human washing machine stands next to the sink and toilet in the bathroom. Instead of jumping into the shower to wake up in the morning and risk being stuck for 20 minutes, maybe more. Instead, you jump into your human washing machine, start the program and feel the warm microscopic bubbles remove dirt and stress from the body. When it’s done, you’re warm and dry and ready for a new day!
The human washing machine has the potential to change morning routines and make them pleasant and personalized. Even for elderly people, or people with disabilities, it could provide a more independent and comfortable washing process.
Man and technology
Humans have always had a divided opinion about innovation and new technology. It is new technology and innovation that has made possible everything we have in our homes today, but sometimes it can be too much. Especially today, where a lot goes from simple, but viable products, to advanced, high-tech ditto that offer us endless functions, but with a limited lifespan and a lot that can go wrong.
Where the human washing machine will fall on this spectrum remains to be seen, but, personally, I definitely see a market for it, albeit a niche one. Today, more people choose, e.g. Japanese toilets, advanced whirlpool baths and shower systems. So, why not a washing machine for you and your family?
However, man is a creature of habit and both the shower and the customary bathtub are central to many people’s lives, which I don’t think will change for quite some time. There is something special about stepping into the shower and feeling the warm water wash over you. For small children or pets, it is hard to imagine that such a machine would replace more traditional solutions.
Location, cost & target group
Many modern bathrooms, especially in big cities, aren’t made for several different types of washing possibilities, but are often limited to a shower or bathtub. There rarely is room to set up a human washing machine – it is often hardly possible for a normal washing machine to fit in. In these types of bathrooms it will be difficult to justify another large machine.
However, many exclusive hotels, hospitals, rehab centers, spas and bathhouses will likely be interested! Here there is an opportunity to create a more luxurious facility with unique, fully automated treatments for its visitors with relatively small funds. As with tanning beds, it is not too unlikely that many people will set up a human washing machine here and there in their facilities.
Technology & Privacy
As with smart speakers and health apps, there is growing concern about how data from sensors can be used and shared. Consumers want to know: Will information about my stress levels and vital signs be stored securely, or shared with third parties? Science Co has not yet mentioned how they will handle this, if the data will be available locally only, or if it will be sent to the “cloud” for analysis.
A few last words
Although the human washing machine is likely to be a luxury product at first, it reflects a wider trend towards technological innovations that combine convenience and personalization – something that could change the way we look at everyday routines in the future. The question is whether this time the public is ready to get into a human washing machine and let AI decide which program is needed right now. Products like robotic vacuum cleaners and Japanese toilets show that even skeptical consumers can embrace new technology when it makes life more convenient.
Whether it becomes an everyday product or a luxury item, the human washing machine shows that the future is here – and it wants to make us both cleaner and happier.
Could you imagine being washed in a washing machine instead of a hot bath or shower?
