This robot floor cleaner was patented in 1957 by Donald G Moore. Controlled by a central console, you only need to press a button and the little robot appears and buzzes around just like the Roomba. It uses similar sensor technology and follows a preprogrammed path around the room so that the entire room is cleaned. One way it differs from the the Roombas on the market today, is one floor unit both vacuums and "mops."
