I was a professional cleaner for 15 years before I discovered this trick. How did I find out about it? A client saw me struggling with a lint roller before I steam cleaned her sofa. It had white cat hair all over it. She said, "Oh, there's a better way than that." She slipped on a rubber glove and took the hair off in about 30 seconds. WOW! No hair removal contraption I've ever seen works as well on upholstery and clothing as this. Try it!
