Jeff,
There are a few rules that come into play here, but the test will be if the device contacting the floor provides traction or braking (more than 5% in any direction) in addition to the wheels provided and that said device does not damage the playing field surface. That second one is far easier to determine. I am guessing you think that that a ball chute that follows the floor is needed to pick up balls. If you were to investigate a little further, I think you would find that the ball diameter is sufficient to allow pickup without touching the floor.
