The Shark Steam & Scrub Automatic Steam Mop scrubs and sanitises* at the same time cleaning with the power of steam. The combination of steam and rotating pads delivers up to 2x better stuck-on stain removal vs. traditional steam mops on hard floors. This deeper cleaning removes layers of dust residue grease and bacteria while providing chemical-free sanitisation that removes 99% of bacteria from your floors. Steam channels evenly distribute steam throughout the mop head for consistent cleaning and a streak-free finish on all sealed hard floor surfaces like tile marble hardwood and stone. Specifically designed Scrubbing Pads rotate 150 times per minute to hold and lock dirt in the pad making them tough on stains but gentle on floors. Shark s steam mop pads are reusable machine washable and quick drying simply throw them in the washing machine. With 4 pads included in the box you ll always have a fresh pair ready to go.
