The Quickie Sponge Mop Refill cleans more floor in less time than other sponge mops. The 11 in. wide sponge is made for the professional cleaner. A dual layered cellulose sponge maximizes the absorbency you need for a quick thorough clean. The cellulose provides deeper cleaning on hard flooring surfaces and absorbs more water off the floor with fewer mop passes meaning your floors dry faster! Not to mention this mop works well on tile grout and any other uneven floor surface. The patented built-in front scrubber helps remove scuff marks and stubborn stains. A butterfly squeezing action feature designed with oversized nylon rollers makes mop wringing easier than ever before. Quickie designs
