Today, the toilet consumes much water. People think that a toilet is never clean. As a common project in our life, i think there are somethings to improve.

The toilet 'drop' is a prospective concept. Thanks to the sensor system, we don't need to touch to use. And the foam water replaces the normal water, we save 80% water for every flush. People sit always on the 'drop', the posture simulates to squat, that is really good for our colons. 

Thanks for your attention.
