> So the toilet cleaner retrains to become the toilet repair person? I once had a summer job as a manager of this issue - my job was to find a cleaning company and assure quality in one company building (roughly 500 toilets, around 30 cleaners). From my experience, these people were unable to properly do their jobs (not the cleaning part, stuff like opening windows so the toilet doesn't smell like acid and actually dries, not forgetting to clean something...). None of these people would be able to or would want to invest the time to learn to repair the incredibly complex Japanese toilets - they will rather live on welfare. Of course it's anecdotal and I'm sure that a lot of people will do just what you said - most certainly not everyone though, and there won't even be place for everyone, rather like every hundredth at most. > Unless you're suggesting that a Japanese toilet is a robot that cleans the whole bathroom? Yes, there are "toilet boxes" that can clean the whole thing including floor, ceiling and walls.
