Roborock Q5 LiDar Sensor Replacement

Introduction

LiDAR (Light Detection and Ranging) sensors are essential for navigation and obstacle avoidance. If the sensor is not functioning properly, it may affect the robot vacuum's ability to navigate and avoid obstacles. It can result in inaccurate data readings and navigation problems if the calibration is off or misaligned.

Regular cleaning may help, but in some cases, replacement might be necessary. It is recommended to troubleshoot the issue to ensure the problem is indeed with the sensor.

The replacement lidar sensor is available on Ali Express. OEM model # is LDS04RR. Here's a link to the correct part (as of Sept 2025): Original Roborock LDS Replacement LDS04RR For Robot Vacuum Cleaner Q5 / Q7/ Q7 Max / S8 Series Accessories Laser Distance Sensor - AliExpress

Before replacing, take a good look at the motor shaft of the lidar sensor - it can get tangled with hair and lint and may be the reason your sensor is not spinning. Cleaning the shaft may save the need for a new part (but not the hassle of dissassembly)
