I tested this vacuum as soon as it was delivered. It was much too heavy and much too noisy- I was so disappointed. I don't know how they can advertise it as under 9 lbs. There was nothing lightweight about it and the vacuum was difficult to maneuver- didn't want to roll smoothly. It's cleaning capability is good. Amazon, true to their word, refunded the cost & I was pleased about that & most certainly will deal with them again and again.
