Key benefits Faster, more effective cleaning: The main brush has fluffier, more elastic bristles that lie closer to the floor to pick up dust, hair and debris on the first pass, reducing repeated cleaning and shortening cleaning time. Restored suction performance: Worn or deformed bristles and tangled debris can block the air duct and reduce suction. A fresh main brush keeps the airway clear so the vacuum's suction can be fully effective and remove deepseated dust. Floor protection: Soft, wellformed bristles reduce hardedge contact and friction that can scratch wood, tile or other floor surfaces, minimizing wear during cleaning. Quieter operation: , balanced components and healthy bearings run more smoothly, reducing abnormal vibration and noise for a more comfortable cleaning experience. Key functions and attributes Function: Direct replacement for a vacuum cleaner main brush to restore brushing action, airflow and overall cleaning performance. Bristle characteristics: Fluffy, elastic and soft bristles that conform to the floor surface for better debris pickup and gentler contact with floor materials. Performance: Improves pickup of dust, hair and debris, prevents air duct blockage, enhances suction effectiveness, and reduces operational noise. Condition: parts are balanced and from deformation or accumulated debris that cause bearing strain or vibration. Practical applications / use scenarios Pet hair and daily debris: Quickly lift pet hair, lint and household dust from carpets and hard floors with fewer passes. Hard floors and delicate surfaces: Clean wood, laminate and tile while reducing the risk of scratches and surface damage thanks to softer, conforming bristles. Deep cleaning and traffic areas: Restore suction and brush performance to reach deeper dirt in rugs and traffic zones without repeated effort. Maintenance tip the main brush when bristles become flattened, bent, heavily clogged or when you notice reduced suction or unusual noise. Regular replacement keeps the air duct clear, protects flooring and maintains cleaning performance.
