Abstract: An automated toilet seat and seat cover lifting and lowering system that eliminates the need for the user to touch any area of the toilet with their hands. The system utilizes the force of pressurized water to lift the toilet seat and seat cover. A lever actuator housing is mounted on the top surface of the toilet bowl adjacent the rear end of the toilet seat. A plurality of lifting levers extend from the front end of the lever actuator housing and they are connected respectively to either the toilet seat or the seat cover. The actuator assembly inside the lever actuator housing has means for using pressurized water to raise the respective lifting levers and the toilet seat and seat cover attached to them from a horizontal position to a vertical position. Remote control buttons located on a wall separated from the toilet can be utilized to lift and lower the toilet seat or seat cover as desired.
