The Xiaomi Mi Robot Vacuum-Mop Pro Side Brush in white is a replacement cleaning component designed to help your vacuum reach dust and debris in corners and along edges. Made from a combination of white PC and nylon, it weighs only 10 g and measures 90 x 90 x 20 mm. The nylon bristles are specifically engineered to be gentle, ensuring that your floors and furniture remain free from scratches during the cleaning process. Because this part is washable, you can maintain it between replacements to extend its utility. Depending on how often you clean, you can expect a lifespan of 3 to 6 months before a new brush is needed to keep your robot performing efficiently.
