The roller brush is usually installed at the bottom of the robot and is divided into two types: main brush and side brush. The main brush is responsible for pushing the dirt on the ground to the suction port, while the side brush helps to sweep the dust on the edges and corners to the main brush for better cleaning. As the core component of cleaning, the convenience of disassembly and assembly of the sweeping robot roller brush is crucial to user experience and machine maintenance. If the disassembly and assembly process of the roller brush is inconvenient, a series of problems may arise;
