Much like the fabric softener bar that BOUNCE created to stick to the inside of your dryer. This will also stick to the inside of your dryer, but for the sole purpose of getting rid of pesky pet hair without the hassle of rewashing and drying. Instead of it being in bar form, it would come in sheet form and attract the hair like the swiffer duster attracts dirt and must also be able to work for the washer as well.
