Robotoi

Most of the time, this well-crafted, gracefully designed porcelain toilet stays in the bathroom. But when you call to it, using any natural-language command, such as "Toilet, come here!", the Robotoi will disconnect from the wall and roll into your living room, or kitchen, or den, following the sound of your voice and using its infra-red sensors to navigate a route thru your house to your present location.

The toilet has sealed itself off at the bottom and it is now a stand-alone commode.

You conveniently take care of your business without ever having to look away from the television set, put down the phone, or stop working on your computer.

Using the toilet paper dispenser that Robotoi has built into it, you clean up, and send it away. Robotoi then returns to the bathroom from whence it came, reattaches itself to the household plumbing, flushes itself, and releases a pleasing puff of fragrant aerosol spray.

It is recommended that you visit the washroom before eating, so that you can wash your hands in a proper manner. ...Wait! Next idea: Robosink!
