Sun & Earth Microfiber Mop Pads are a better, eco-smart option than disposable covers or pads that are used once then thrown-away.  Machine washable, they perform effectively on nearly all hard surfaces.  When used  

The technology used in the microfiber makes for superior cleaning capabilities.  With fibers that are 100 times thinner than a human hair, absorbing power is quicker than normal cotton.  The fine texture/pores absorb water as well as lift and trap dust, dirt, and grime.
