Introduction
If your Roborock Q5 Max Plus side brush has stopped spinning, moves erratically, or triggers repeated error messages, the side brush motor may need replacing. While this component is built to last, years of regular cleaning, especially in homes with pets or high debris, can eventually wear it down. This guide will show you how to safely replace the side brush motor and restore proper edge-cleaning performance. Be sure to power off the vacuum and remove it from the dock before starting any repairs.
