The Shark touch-free dirt grip washable pad is an advanced multi-material microfiber steam mop pad that loosens and lifts and locked-in dirt, while cleaning, sanitizing, and drying sealed hard floor surfaces in seconds.Compatible with both the genius mop head and the intelli-mop head, the touch-free, two-sided dirt grip pad has double the cleaning surface and better absorption than previous models. The dirt grip pad's surface is a mixture of materials: a super-absorbent microfiber for locking in moisture and dirt, and a scrubbing material for breaking up tough, stuck-on stains and grit for a faster, more efficient cleaning experience.Dirt grip materials are fully reusable and washable, so you can start with a clean pad every time you mop, helping to avoid streaking and ensuing that maximum cleaning is achieved every time. Recommended for up to 20 wash cycles, dirt grip pads are a clear improvement over disposable pads, with more absorbency and more effective deep cleaning ability. Sanitization studies were conducted under controlled test conditions. Household conditions and results may vary. With genius or intelli-mop head in scrub mode only.
