Featuring Super Cell Sponge™ technology – a dual layered cellulose sponge for maximum absorbency. The durability of cellulose provides deeper cleaning on hard flooring surfaces. Cellulose absorbs more water off the floor with less mop passes so floors dry faster! The patented built-in front scrubber helps remove scuff marks and stubborn stains. The automatic squeezing action makes wringing a breeze.
