Query: Best thing since sliced bread!!!

I was not sure if this thing would work, but I have to wonder how I lived without it! I have 3 kids and 3 inside dogs, and this is a life saver. It cleans 100% better than my central vaccuum. My husband accidentally dropped it and broke off the front wheel. One call later they said send it in and they will replace and clean it. I was back like new within 2 weeks- faster than I ever expected. I love it, was thinking about getting another one, putting eyes on it and name it spot.
