These mop heads are compatible with System 1492 and 1283. They are not compatible with other systems. Includes: 4 pack refills (handle not included). The mop head is made from highly absorbent microfiber. The extra-large size covers a larger area, absorbs more moisture, and dries floors quickly. It makes full contact with the floor and, when used with water, effectively removes dust, dirt, and debris from tile and wood floors. Easy to replace, machine washable, and durable for long-term use. Safe for use on all hard surfaces, including hardwood, tile, vinyl, laminate, marble, and glass. The fabric is easy to wring out, reducing drying time. This is an unofficial accessory designed for effective cleaning. It serves as an ideal replacement for worn mop heads or as a spare.
