I've had my Swiffer for years now. Never really had a problem with it until I opened up a new box of 24 refill pads and they don't stick. Maybe they're defective? There was nothing on the box that states that they wouldn't work with the older models. I would hate to have to buy a new one just because I can't use the refills. My original Swiffer works fine, I just need refills that will stick.
