This is my second vaccum of this model. I purchased one of the first ones, when they came out with it, due to I have 6 very large dogs. This is the best vaccum I have ever purchased. It has such suction that none can compare. I totally burnt up and wore out my first one since I have to vaccum everyday. I was thinking about checking out some other models but after researching and investigating I changed my mine. I knew this was a great one and hated to change. I am very hard on a vaccum and this stood up great. The other main selling point that I feel deserves a hats off to is, the removeable canister--- so I can vaccum my stairs. It is a wonderful invention. I had no difficulties when ordering this vaccum or recieving this item. Delivered as it stated and it came undamaged with very little assembly. Thank you Overstock for the bargain. I will be back!
