A team of student researchers from the US led by 22-year old mechanical engineering graduate Nick Bradford have developed a new toilet seat cleaning system, which requires no chemicals, rotating seat sleeves, electric or battery supply and works like a mini carwash.
The system uses water from the plumbing which is diverted into a cleaning mechanism that is enclosed in the toilet lid. The water flows under high pressure to three arms mounted on a rotating disc, and the force of the water rotates the disc to clean the toilet seat.
The design of the system eliminates the need for expensive motion sensors that deliver a plastic seat cover whenever a person enters the cubicle.
