The Dreame RMB10 is a replacement main brush designed to keep your robotic vacuum running efficiently by tackling one of the most common maintenance hurdles. Its specialized TriCut design automatically cuts through human and pet hair as it cleans, which prevents long strands from wrapping around the roller and clogging the mechanism. Finished in black with gold accents, this brush is compatible with a wide range of advanced models, including the L10s Ultra, L20 Ultra, L30 Ultra, L40 Ultra, and the X30 and X40 Master series. It provides a practical solution for households with pets or long-haired residents, reducing the time you spend manually cutting away tangled debris to maintain peak suction performance.
