Floor protection: Prevents scratches on wood, tile, or other floor surfaces, helping maintain the floor's appearance over time. Easy cleaning and maintenance: The guard is designed to be disassembled for separate cleaning, making maintenance faster and more convenient than cleaning the entire main brush. Reduced hair tangling: By reducing direct contact between hair and the main brush, it lowers the risk of tangling and keeps the cleaning process smoother. Main brush protection: Shields the main brush from direct contact with the floor or rough surfaces, helping to reduce friction and potential brush wear. Function and compatibility: Designed to fit compatible main brush assemblies on select floor cleaning devices. Check product specifications to confirm model compatibility. Size and material: Sized to align with standard main brush configurations on compatible devices. Material details are provided in the product specifications. Performance: Improves floor protection, simplifies maintenance, minimizes hair tangling, and helps extend the life of the main brush. Use scenario 1: In homes with hardwood or laminate floors, the guard protects finishes from scratches during daily cleaning. Use scenario 2: In households with pets or heavy shedding, the guard reduces hair tangling on the main brush, speeding up cleanup. Use scenario 3: Between deep cleans, you can detach and clean the guard separately, then reinstall for quick ongoing maintenance. Care and installation: Install the guard onto the main brush assembly as instructed by the product manual. When dirty, detach and clean the guard separately, then dry before reattaching.
