My vacuum has the ability to fill air matresses, so all that I need is an entention to fill a sport ball. I'd rather that over an electric ball pump because they're priced at $60+ and probably not as good!
No. You could rig something though. Do you have 100 balls to fill or something? It takes very little time to fill a ball by hand.
get a bicycle pump and a needle to inflate sports balls.
Vacuum cleaners don't generate enough pressure to fill a sports ball.
