Query: Great vacuum for a $100

After reading all the reviews on different vacuums, I came to the conclusion that there really is no "perfect" vacuum. I went with the Bissell 3910 because it appeared to have the best reviews for a vacuum in this price range.Pros: It was easy to assemble and light weight enough to carry up the stairs. I didn't have any problems detaching the hose from it's base like others have written nor did I mind the 35' cord. Ergonomically, it was was easier on my back and moved effortlessly as if it as self-propelled. If you are tall, you will like the height of this vacuum. The canister was easy to empty. I went from carpet to hardwood floors without any problems.Cons: The hose could be longer. The dial to set the vacuum level seems to vibrate to other settings. Also, the beater brush did not always stop in the bare floor mode which I think it should. Like I said, no vacuum is perfect.
