We gave you an exclusive look at our test drive of a Scooba at my house awhile back, and now we have the full results. It wrestled with my wife's dresser and scared the cat but, in the end, did a great job on the floors.
If you shut it up in the bathroom for 20 minutes and ignore all the bumping and buzzing, you can come back and find the tile floor clean and sparkling. We tried to send it over the stairs, but sensors planted underneath make it veer away from heights. If you're looking for a gift, it's not a bad idea, although at $399 it's a bit steep. (You can return it after 30 days if you haven't destroyed it.) You can also get a remanufactured Roomba vacuuming robot for $109.
