ABSTRACT:
A self-sanitizing toilet seat cleaning apparatus includes a seat in the shape of a generally circular ring that is rotatably mounted above the toilet bowl and includes a gear on its underside meshing with a pinion gear attached to the drive shaft of a drive motor for the seat. An arm extends over a rear portion of the seat and includes flow passages that convey a disinfectant on top of the seat, under the seat, and into the toilet bowl. Under the arm, a wiper is provided that wipes the top surface of the seat as it rotates. The toilet includes a weight sensor that stops rotation of the seat if a person is sitting on it and a proximity sensor to activate flushing of the toilet and rotation and disinfecting of the seat and bowl.
