Key benefits Faster, more efficient cleaning: The main brush has fluffier, more elastic bristles that hug the floor and lift dust, hair, and debris more effectively, reducing repeated passes and shortening cleaning time. Restored suction and airflow: Replacing a worn brush prevents bristle deformation and debris entanglement that can block the air duct, allowing the vacuum to reach full suction power and remove deepset dust. Floor protection: Soft, wellformed bristles reduce hardedge contact and friction that can scratch wood floors or tiles, helping protect floor surfaces during cleaning. Quieter operation: A main brush with balanced bristles and good bearings runs more smoothly, lowering operational noise and improving user comfort. Function and performance Purpose: Direct replacement for a worn main brush to restore brush contact, airflow, and mechanical balance. Bristle characteristics: Fluffy, elastic, and soft for improved pickup, adhesion, and gentle floor contact. Performance outcomes: Faster debris pickup, improved suction efficiency, reduced floor wear, and less running noise. Practical applications / use scenarios Homes with pets: Quickly lift pet hair from carpets, rugs, and upholstery while preventing hair buildup that can reduce suction. Hard floors and tiles: Clean dust and fine debris without scratching wood, laminate, or tile surfaces. Deepcleaning carpets and edges: Restore brush action to reach embedded dirt and maintain airflow for better suction on carpets and along baseboards. Maintenance notes the main brush when bristles are visibly worn, deformed, or tangled to restore cleaning efficiency and airflow. Regularly remove hair and debris from the brush to prolong life and keep the air duct clear. This replacement main brush restores the vacuum cleaner's intended function—improving cleaning efficiency, suction, floor protection, and noise level—by returning brush bristles and components to proper condition.
