This is going to be the coolest thing! iRobot, the makers of Rooma the robot vacuum cleaner are coming out with the Scooba. The scooba is a Robotic Floor Washer and its exactly what I need for my hardwood floors. The scooba works by first vacuuming up the flotsam and jetsam, then applying a liquid cleaner, and following up by drying the floor. Its coming out in the fall so it will be on my Christmas wishlist.. Videos and more info here. Here is a picture of my roomba in action.
