Super Absorbent Material: Made from 80% Polyester and 20% Polyamide, our microfiber steam mop pads provide effective cleaning with strong water absorption. They dry quickly and are designed for long-lasting durability, resisting fading even at high temperatures, helping you cut expenses on replacements. Size & Attention: This is a standard size mop pad and does NOT fit the XL (extra large) mop head. Please verify your rectangular mop head size to ensure compatibility. Note that these pads do NOT fit the S3601CO model, which has one wider and one narrower rectangular mop head. Machine Washable & Reusable: Featuring a Velcro closure to keep the pad securely in place, these pads do not shrink in the wash and can be used on both sides, providing great value and performance. Ideal for Hard Floors: Our pads glide smoothly across floors without getting stuck or skidding. They effectively trap dust and pet hair instead of just pushing it around, ensuring your floors are left spotless after use.
