This item is described as flat, for cleaning under limbs and the like. It was sent in a folded tube, which was left under piles of books for three days to straighten it. Then, when used, it would always return to its folded form. Virtually useless to use. And it is not suitable for ordinary vacuum hoses. I had to cut the clamp to fit my regular Bissel type vacuum hose. It's not expensive, but more than worth it.
