So far so good
I love this thing. My floors are cleaner now than ever before. This is a must have- especially if you have hardwood floors and cats as I do. As an added bonus the cats are really fascinated by the little guy. The only real drawback is the dirt compartment fills fast- which is why I drop to 4 stars. As a result, you need to empty it after every use- meaning you can not schedule the little guy more than once if you are away from home on vacation or business. That said, I am still happy with the purchase!
