Picks up over 5 times more liquid than a regular mop and locks it in place so it doesnt drip. Dont just push around water like a regular mop; the PVA mop cleans, absorbs and dries. The sponge absorbs the water as you mop, so your floors dry in minutes instead of the half hour wait you get from other mops. Roller mop head refills only, no handle included.
