The replacement parts kit is compatible with Eufy RoboVac 11S, RoboVac 15C, RoboVac 30, RoboVac 30C, RoboVac 2, and RoboVac 35C vacuum cleaners. This roller brush is made of high-strength materials, durable, delicate, and soft, capturing 99.99% of particles released during cleaning, including particles as small as 0.3 microns, and expels non-allergenic fresh air. The roller brush sits close to the ground, moving dust and hair into the groove through high-speed rotation. A quiet clean rolling brush design significantly reduces vacuuming noise, providing a quieter environment for your home and daily activities. Regular replacement of roller brushes helps maximize cleaning performance. Especially in homes with pets, it is recommended to replace the roller brush every 2-3 months.
