Imagine – you have bought a Roomba. If you do not know what a Roomba is, it is a robot vacuum cleaner, made by iRobot that looks like a discus with brushes, buttons and wheels that vacuums your house for you while you are not there. Before you go out you remember to switch it on to conveniently vacuum the house while you are away. You get back a little later and enter the room where the Roomba perhaps is still working away.
