Self-Cleaning Seat
March 1, 2003

This plastic toilet seat cleans and sanitizes itself in 15 seconds by rotating through a hygiene sluice that dispenses a citrus-scented, germ-killing solution on the seat's surface. SCS Self-Cleaning Seats fit on traditional commercial toilets in which the water tank or reservoir is behind the wall or mounted high above the fixture.
