After cleaning with the Libman Wonder Mop, you may wonder how you cleaned without it! Each Wonder Mop head is constructed out of our unique GRIPSTRIPS , designed to lift up to 20% more dirt from your floors, leaving them even cleaner. The Wonder Mop has a built-in plastic wringer, designed to squeeze out and remove more water from the microfiber mop head. This allows your floors to dry faster so you can be back on them sooner. The mop head is also eco-friendly, thanks to being machine washable up to 50-times -- keeping disposable cleaning pads out of landfills. Simply remove the head, wash, and reinstall it to keep cleaning. The Wonder Mop is great on all floor surfaces.
