The central question that those of us who don't own a Roomba robotic vacuum cleaner have often wondered: Does it really clean the whole room? Now, thanks to a personal project by signaltheorist.com, we have our answer: Hell yes, it does. Here's the explanation from the site: "I set up a photo camera in my room, turned out all the lights and took a long-exposure shot of my Roomba doing it's thing for about 30 minutes. The result is a picture that shows the path of the Roomba through it's cleaning cycle, it looks like a flight map or something. It really hits every spot!" It's certainly a better advertisement for the product than this old commercial.
