The Scooba is the only robotic mopping system I have ever seen. It is the next step in an evolutionary process that will one day bring us the cooking/cleaning/shopping robot of the future. Even if you don’t want to take it apart, it is nice to hit a button and come home to a clean floor. However, if peeking under the hood of a device is SOP (standard operating procedure) for you, then the Scooba should keep you amused. At roughly $400, though, you might want to think twice before poking around its internals. One minor goof, and you will have yourself a rather expensive stepping stool.
