The ""bowling ball vacuum"" is a phony sales pitch term. They use a canister vacuum to demonstrate how it can pick up a bowling ball. What a joke! Ha Ha. If you don't believe me, go in there and detach the hose fitting from the vacuum and put the nozzle on the bowling ball and then just breath in with your mouth through the other side. It will pick up the bowling ball with ease. Ha Ha. What a fake way to con customers into buying their product! Not only that, but you also get the worst service possible with the manager there who's name is Scott. He has the worst attitude out of any retailer I have ever delt with. And you will get ripped off in a heart beat by this guy if you go here. Oreck isn't interested in your needs but instead they are all about money in there pocket, plain and simple. All the Oreck dealerships are nothing but ""con artists"" waiting to shaft anyone who walks through there door. Don't get one, they are junk.
