Microfiber floor cleaning is not only friendly to the environment, it's friendly to your floors as well! Microfiber is also an excellent choice because it is easy to use, it lasts a long time and it does an amazing job of cleaning your floors. Microfiber is better for cleaning than traditional sponge mops because it picks up more and doesn't simply spread the dirt around. It's better for the environment than using disposable cleaning pads. And the pads are washable. Set of 5 helps ensure you always have a clean pad ready to go!
