Our team tried to use a vacuum suction system last year for ball acquisition. Let's just say it didn't go well. First of all, it can be very heavy and space consuming, since the vacuum can weigh a ton, depending on what parts you use. Second, it is very unreliable, either not having enough power to pick up a ball, or having too much power and not letting go. I suggest using either something with pneumatics or surgical tubing/spring type system. good luck!
