The inner wall is ultra‑smooth and polished without burrs, which greatly reduces air resistance and dust adhesion, maintains strong and consistent suction power, and improves cleaning efficiency. With high toughness and anti‑breakage design, it is resistant to bending, stretching, extrusion and daily wear, not easy to crack or deform, providing long‑lasting durability for long‑term use. Excellent sealing performance effectively prevents air leakage and dust leakage, ensures full utilization of motor power, and delivers stable and powerful suction for better cleaning effect. Lightweight and flexible structure reduces the weight burden of the whole machine, making the vacuum cleaner easier to handle and operate, bringing more comfortable and effortless user experience. Resistant to high and low temperatures, it will not become hard in cold environments or soft and deformed in high temperatures, maintaining stable performance in various using scenarios., Manufacturer: dlm0507
