It's simple: Spritz the broom with a cleaner before sweeping. When I asked her why, she shrugged and said, "It helps with the hair." Turns out, the reason it works has less to do with the hair itself and more to do with static electricity. Pet fur picks up static charges from rubbing against carpets, furniture, and fabric (or maybe that perpetually squashed dog bed). That's why it's so stubborn to sweep up.
