When my daughter is home from college, our vacuum gets a workout. She's never been able to tolerate a gritty floor or dusty corner, and lucky for me, she loves to whip out our trusty Dyson and go to town on every nook and cranny. (With three cats in our small apartment, she's got her work cut out for her.) When she's not home, it's a different story—which got me wondering: What would happen if a person didn't vacuum for, say, a whole month?
