4 PCS Duster Kit includes: 5-13 ft extension pole (not included human height; stainless steel rods can be installed according to requirements), bendable microfiber duster head (18 in), chenille duster head, spider web duster head, and a window squeegee. Replacing different duster heads enables cleaning in various scenarios, keeping your home free of dust. Extension Duster: extends from 5 ft to 13 ft (pole length; duster head size not included). Choose the length you need to reach high spots and behind furniture, avoiding ladders and enabling safe cleaning at any height. Washable Duster: easy to disassemble and wash. Remove the duster head from the pole, wash with water or machine wash, then hang in a ventilated place for next use. Farewell to spider webs and dust: the microfiber duster head generates static electricity during use and easily attracts dust, pollen, and hair. The fluffy microfiber and soft rubber top ensure that sofa, furniture, or wall surfaces are not scratched during cleaning. Use scenarios: - Reach high ceilings, crown molding, ceiling fans, and behind tall furniture with the extension pole. - Clean window sills, blinds, and glass surfaces with the window squeegee. - Dust sofas, walls, and other surfaces without scratching, using the microfiber and rubber provided.
