Ming Wang has meticulously developed filaments tailored for premium robotic vacuums. Materials such as PA612, PA66, PA6, and PBT exhibit superior abrasion resistance, fatigue tolerance, and flexibility. They boast excellent rebound and flexural recovery, as well as high heat resistance. Even at high speeds, these filaments remain shed-free and retain their shape, preventing tangling and effectively prolonging the lifespan of the robotic vacuum's side brushes.
