Take your cleaning to the next level with the Heavy-duty Wonder Mop. It has everything you love about the Wonder Mop as well as the ability to clean larger areas and an integrated scrub brush to remove hard, stuck-on messes. The mop head features a 45% bigger mop head, with 10 In. long versions of exclusive antibacterial GRIPSTRIPS material, and is designed to lift even more dirt. It removes over 99% of Staphylococcus Aureus and E. Coli on ceramic tile and wood floors when used with water, while also being machine washable up to 50 times. Simply remove the head, wash, and reinstall it to keep cleaning while keeping disposable cleaning pads out of landfills. A built-in power wringer squeezes more water, allowing floors to dry faster.
