Love those map pad refills.They are perfect for hard floor or wood floor cleaning.It is a complete clean in one pad- it vacuums,locks away debris and absorbs.It is disposable hard floor pads,one pad is enough to clean floors in the house.So easy to use just clip it on your shark vacuum mop vacmop and ready to go.We have tiles and wood floors and this mop pad refills just made every day floor cleaning easier,as we have dogs and dog's hairs always been a problem for us,but now we can have a clean floor every day,even my kids love using it.
