Compatibility and purpose Direct replacement side brush motor for 1C STYTJ01ZHM and D9 / D9Pro / D9max / L10Pro robotic vacuums. Designed to the original side brush motor without modifying the vacuum's structure or other components. Key benefits (why you need it) Restores reliable sidebrush operation so edge and corner cleaning performance returns to factory levels. Stable power output during use keeps the side brush spinning evenly, improving debris pickup along baseboards and in narrow gaps. Durable core components resist wear under continuous rotation, reducing the frequency of future repairs and extending the service life of the side brush and the robot. Performance and construction Manufactured with standardized craftsmanship to ensure consistent, repeatable operation. Core parts are made from wearresistant materials and engineered to handle longterm rotational load. Optimized for steady torque and rotation speed to maintain effective cleaning along edges and corners. Ease of installation Includes a clear installation guide for stepbystep replacement. Can be installed by users without professional experience; operation is straightforward and convenient. Fits into the original mounting points and electrical connections for a plugandplay replacement. Practical applications / use scenarios Routine maintenance: a worn or failing side brush motor to restore edgecleaning performance and avoid buying a robot. Performance recovery: When the side brush slows, vibrates, or stops, swapping in this motor brings back consistent rotation and cleaning efficiency. Preemptive service: Install during scheduled maintenance to reduce downtime and extend the overall lifespan of the vacuum system. What to expect after replacement Improved corner and edge cleaning as the side brush regains proper speed and stability. Reduced noise and vibration compared with a worn motor. Longer interval between subsequent sidebrush or motor services due to durable materials and consistent manufacturing. Notes Fits only the listed models: 1C STYTJ01ZHM, D9, D9Pro, D9max, and L10Pro. Ensure model compatibility before . Replaces the original side brush motor; no structural modification of the vacuum is required.
