This might help some people, I took a video last night of a standard home vacuum cleaner hose onto a soccer ball, and it works well. You get a good suction, and the ball stays with the hose unless you move it side to side really fast, which is a problem, but overall it works well. And the seams of the soccer ball have no effect at all. It can even pick up the ball straight into the air when it is directly on a corner seam.
