As usual I was skeptical. A year ago I had purchased the Roomba 770. I admit I didn't expect much. And figured it would maybe pick up a bit of dirt to help me out. After using the Roomba, it exceded my expectations. For a year I have been looking at the Scooba. The price was steep. And once again I didn't expect much. Finally I broke down and bought it. The Scooba exceded my expectations too. I am very pleased with it. The Scooba helps me out as much as the Roomba. I can multi task and get much more done in less time with the aid of these products. The Scooba is great! I am very glad I finally bought one. It isn't perfect that is why I gave four stars. But this gal isn't complaining about my little robot!
