I've had mine for 5 years. For the most part I like it although I have never liked the bulky wands and hose handle. The hose handle is slightly smaller though than on the 6500 and 9000 that I had. When I visited the vac museum Tom gave me a brush roll with stiffer bristles - it made the world of difference to the effectiveness of the power nozzle. Mine does not shut off either when the bag is full - only the light turns on. Also it will run with no bag in place. Although the bags are small, they hold a lot of dirt and get packed solid before the light comes on.
