Query: Most worthless appliance I ever bought.

I purchased this item from a traditional vendor. It was absolutely worthless! It is literally so loud you have to wear hearing protection to use it or your ears ring for several minutes afterward. Most of the water it sucks up gets sprayed back out the exhaust vent and all over your clothes and the room you are using it in. I threw it out after a couple of times using it. Don't waste your money.
