After the Vacuum cleaner, this great complex mechanical WC.
I ask me if we couldn't to join the both, for our individual daily use; a ThroneVaccum or VacuumThrone.

I like this Throne; by Principle or Prince, nobody works enough on the seat that everybody uses all the days during all his life. It will be nice in my Dining room, may be also in my library where I don't have a lack of paper.
