Abstract: A toilet has a first bowl connected via internal passages to a water tank having a hand-operable valve, one or more remotely-operable spray openings, directed upward, and a connected passage to a sewer line, and a second bowl, rotatable and joined to the first bowl, and operable by a lever in a manner that the second bowl maintains an upright position, or an inverted position facing downward into the first bowl, Urine or feces in the second bowl at a time of moving the lever from the first position to the second position, as the second bowl is moved to the inverted position, is dropped into the first bowl, the second bowl, inverted, is spray-cleaned by operation of the spray openings, and the cleaned second bowl is returned to upright position by moving the lever back to the first position.
