Main Roller Brush Cover — Compatible with EXVAC660, EXVAC680S, EXVAC880 Key benefits Restores proper brush function: replaces worn or damaged cover to ensure the main roller brush stays secure and rotates as intended, improving cleaning consistency. Durable construction: made from quality materials for longer lifespan and better resistance to wear and tear than a compromised cover. Direct fit for listed models: engineered to match the original cover dimensions and attachment points for EXVAC660, EXVAC680S, and EXVAC880 robotic vacuum cleaners, enabling reliable replacement without modifications. What it does Protects the main roller brush and its bearings from debris and impact. Keeps the brush aligned and stabilized so it maintains consistent contact with the floor surface. Helps prevent hair and large debris from interfering with brush rotation, supporting better vacuuming performance. Important attributes Compatibility: specifically for EXVAC660, EXVAC680S, EXVAC880 robotic vacuum cleaner main roller brush assembly. Material: constructed from quality, wearresistant materials to extend service life and reduce the need for frequent replacements. Fit and function: designed to match original part size and mounting points for straightforward installation and reliable operation. Performance impact: contributes to even brush rotation, reduced brush wobble, and improved overall cleaning results. Installation and maintenance Designed as a direct replacement for the original cover — remove the old cover, align the cover with the main roller brush assembly, and secure it in place according to your vacuum's service instructions. Inspect periodically for cracks or excessive wear; if damaged to avoid further brush or motor strain. Clean any trapped debris or hair during replacement to maximize brush performance. Practical use scenarios Routine replacement: restore brush alignment and cleaning performance after months of use or if the original cover shows signs of wear. Pet households: reduce interference from pet hair and protect the brush assembly from clogging and abrasion caused by frequent hair pickup. Postimpact : a cracked or damaged cover after accidental bumps or collisions to prevent damage to the roller brush and maintain safe operation. Compatible with EXVAC660, EXVAC680S, and EXVAC880 only. the main roller brush cover to maintain brush performance and prolong the life of your robotic vacuum.
