Roomba Pac-man Game
Imagine you have a cleaning rig like this. Your house will be spotless! Utilizing five different Roombas instead of only one, this Pac-Man Roomba set-up insures that you have a little amusement while the Roombas do their jobs. The genius creator behind the Roomba Pac-Man game has also rigged the system up so that the ghost Roombas can distinguish the Pac-Man Roomba from the rest, thus setting into “chase mode.” Alright, enough talk, let’s get cleaning. Check out this video, it might just turn you into a houseman!
