Query: Vacuum too strong?

Even after the reworking of this item's design, it still collapses as soon as the vacuum is powered on. Absolutely nothing could enter the tube when it was "sucked" closed and flat. Maybe if your vacuum is lacking power from the start, it might work. I used with a Hoover Wind tunnel upright and it was a total loss. According to many reviews, the tube used to be shipped folded with kinks. The new longer packaging allows for the tube to ship without any folding. So this was not the cause of the tube collapsing flat.
