Roborock Q5 Pro: Laser Distance Sensor Replacement

Introduction

This guide will show you how to replace the Laser Distance Sensor (LDS or LiDAR) of Roborock's robotic vacuum Q5 Pro.

You may want to do so if your robot reports "Error 1: Laser Distance Sensor blocked."

Within the guide I will also outline how to replace just the motor that spins the LDS, as well as how to clean it properly.

I recommend reading the entire guide before starting the disassembly, then following steps as needed during.

If you already know how to disassemble it or have followed my teardown guide, skip to step 11.

    • Remove the rubber band using some tweezers, forceps or your fingers.

    • Make sure to clean it. This one was quite dirty, which was causing the motor to seize.

    • Your robot may have a different iteration of the LDS, which has a cover over the rubber band section. In that case, please check: Roborock Q Revo: Laser Distance Sensor Replacement and skip to step 12.
