General description The 3 Pack Replacement Parts Rolling Brush is designed for compatibility with RoboVac models including 11S, 15C, 30, 30C, 2, and 35C. Made from high-strength materials, these brushes are delicate yet effective, capturing 99.99% of particles as small as 0.3 microns and expelling non-allergenic fresh air. The roller brush operates close to the ground, efficiently moving dust and hair into its groove with high-speed rotation. Its quiet design significantly reduces vacuuming noise, creating a peaceful environment. Regular replacement of the roller brushes is recommended every 2-3 months, especially in homes with pets, to maintain optimal cleaning performance.
