Query: only good on carpets

Since we got wood floors, with area rugs, we never use our Roomba anymore. It doesn't handle the uneven surface well. It also gets stuck a lot, and it's just easier to whip out the old vacuum cleaner. The old one picks up the dirt much better, too, and doesn't need to be emptied as often. Wish we hadn't bought the Roomba -- a good idea, but not a great product.
