The Roomba autonomous vacuum / kitten transportation vehicle may be able to go potty all by itself like its cuddly counterparts if these patent applications from iRobot ever come to fruition.

There are no guarantees that we will see a Roomba capable of cleaning itself anytime in the near future, but it does seem like the next logical step. [Robot Stock News]
