Can a Pentair (Rainbow) Pro Vac vacuum head be used in a pool with a vinyl liner? Pentair's website describe these as residential & commercial vacuums but does not state if they are suitable for use with vinyl liners. I called Pentair and the customer service rep had never been asked this question before. She spoke with her supervisor who said that the ball bearing wheels could scratch the liner.
What do the pro's use when they clean residential pools? I am looking for a better vacuum than the triangle head the pool builder provided.
