We modern woman need a device easy to use, light and clean, in order not to have to go to the toilet every time we need it, such as a kind of vacuum cleaner adapted to women's anatomy, because women's toilets are usually far from acceptable and sometimes too far from the working place. It would be a relief for millions of working women. I know teachers that don't dare to drink enough because they're afraid of having to go to the lue during the class.
