    Abstract: TOILET MAID is a product to keep toilet bowls clean with a liquid cleaner. It is composed of two major parts; a reservoir capable of being refilled and a float lever to control output. System is installed in toilet tank with 2 hook hangers. The float system opens the hole in the reservoir when stool is flushed and water drops allowing float to drop. When the water rises the float rises and shuts off hole in reservoir. This constant use keeps the toilet clean and avoids cleaning with brush and severe chemicals.
