I'm afraid I'm not a fan of Swiffer anymore. You spray a chemical on your floor, swish the chemical plus the dirt and bacteria around on your floor, then throw away the portion of the dirt and bacteria that happened to stay on the pad. The rest of the dirt, the chemical residue, and the rest of the bacteria are still on your floor after all that work! Then as new bacteria move in, they slowly become resistant to the leftover chemical AND the dirt/bacteria are being attracted back faster than ever by that moist, smelly residue you've covered your floor with.
To me, mopping (even with a swiffer) is hard work and when I'm done, I don't want my floor to be even dirtier than when I started. What's the point? So now I use a microfiber mop from a company called Norwex that I purchased at a home-based sales show a friend had. It has an adjustable handle, a base with velcro on the bottom just like Swiffer, a dry pad that I use first for picking up dry dirt/debris, and then a wet pad that literally just gets everything, even tough spots, using just WATER! It removes 99.9% of the bacteria without leaving anything behind and then it has silver embedded in the microfiber that kills off the bacteria on contact. I like removing things from my floor, not just swishing them around, and then I can just toss the mop pads in the wash and not create any waste.
