Xiaomi ROBOROCK S5 Laser Distance Sensor Motor Replacement

Introduction

This guide demonstrates how to replace the laser distance sensor on your Roborock S5 robotic vacuum cleaner. The laser distance sensor is the periscopic orange laser on top of the Roborock S5 that swivels around and allows the robot to tell where it is in the room.

If your robot is reading "Error 1: Laser Distance Sensor" there is a good chance you may need to replace the motor that drives the laser. For additional information, check on the Roborock S5 Troubleshooting page.

Before you begin, power off your robot vacuum.
