Why you need this main brush cover Stops dust from escaping: the imported Bayer sealing strip provides firm, deformationresistant sealing that prevents dust from flying while the sweeper runs, improving overall cleaning results. Restores reliable operation: replacing a worn or cracked cover brings back proper brush containment and helps your robot vacuum work more effectively. Built to last: made from plastic, the cover resists wear and maintains shape through repeated use. Key benefits at a glance tightness: Bayer sealing strip ensures a secure, longlasting seal around the brush area to reduce dust leakage. Durable material: quality plastic construction resists cracking and deformation for consistent performance. Enhanced cleaning efficiency: precise fit and craftsmanship keep debris directed into the suction path, improving pickup and reducing recirculation. Easy replacement: designed for quick installation and removal so you can swap old or damaged parts without tools or professional help. compatibility: engineered to match a wide range of sweeping robot brush assemblies for straightforward replacement. Important attributes Function: main brush cover prevents dust from escaping, protects the brush assembly, and helps maintain suction efficiency. Material: plastic body with imported Bayer sealing strip for durable, deformationresistant sealing. Fit and form: compact, formfitting design for reliable contact with the brush area and effective containment of dust and debris. Performance: improves working efficiency of the sweeping robot by keeping debris in the suction path and reducing airborne dust. Typical applications / use scenarios 1. Daily home cleaning: a cracked or loose brush cover to reduce dust escape while vacuuming hardwood, tile, or lowpile carpet, improving indoor air quality during routine cleaning. 2. Pethair maintenance: use the cover to keep hair and dander confined to the brush path so the robot can pick up pet hair more efficiently without spreading it back into the room. 3. Workshop or garage touchups: install the cover when using your sweeper in dusty or lightdebris environments to minimize dust clouds and protect internal components. Installation and care Quick, tool replacement and removal for routine maintenance. Inspect the sealing strip and plastic body regularly; when the seal shows wear or the cover becomes cracked to maintain cleaning performance and prolong the life of the sweeper. This main brush cover delivers improved sealing, durable construction, and easy replacement to help your sweeping robot clean more effectively and reliably.
