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.

Tools

Step 1

Power off your Roborock and place the device on a flat surface with the wheels facing up.
Position the robot so the five-pronged side brush is on the bottom right side.

Step 2

Use a Phillips #2 screwdriver to loosen the single side brush screw.
The screw is attached to the side brush so they cannot be separated.

Step 3

Lift the side brush up and off.

Step 4

Use a Phillips screwdriver to remove the seven 15 mm screws from the bottom panel.

Step 5

Gently lift off the bottom panel cover.
If the bottom panel is stuck, use a plastic spudger along the edges to gently lift it out of place, then remove it by hand.

Step 6

Use the two white straps to lift the battery out slightly to reveal the battery connector.
The battery is still connected to the robot vacuum. Take care not to strain the battery cable.

Step 7

Using moderate pressure, squeeze and pull on the four-wire connector to disconnect the battery from the robot vacuum.
