Query: This vacuum is worthless

I didn't even want to give this vacuum 1 star. It stinks to put it nicely. I don't know what they souped up the one with in the infomercials, but it isn't the one they sell to the public. This thing can't pick up regular, non-ground in, sand off a hard floor or a simple, flat doorway rug. Then, after limited use because of it's worthlessness, it blows up and falls apart. Worthless, I am completely UNsatisfied.
