Roborock Error 1 — LiDAR Sensor Fault (Fix Guide)

What Does This Error Mean?

Roborock Error 1 means the LiDAR sensor (the spinning dome on top of the robot) cannot rotate or read properly. The most common causes are a physical obstruction around the dome or the robot starting in a space too small for the LiDAR to calibrate.

Affected Models

Roborock S5 Max
Roborock S6 Pure
Roborock S7
Roborock Q5+
Roborock S8 Pro Ultra

Common Causes

Something is touching or blocking the rotating LiDAR dome on top of the robot
Robot was placed under a table or in a space too confined for LiDAR operation
Hair or a thin object has wound around the LiDAR dome shaft
LiDAR dome is dirty and the laser cannot get clean reflections
LiDAR motor has failed (requires service)

How to Fix It

Move the Roborock to an open area — at least 1 metre of clear space in all directions. Place it on the floor and press the power button.

When the robot starts, the LiDAR dome spins up and sweeps the room. If something is within range that blocks the laser, the robot may interpret this as a sensor fault.
Inspect the transparent dome cover and the base of the dome for any objects, packaging material, or hair that could be touching or snagging the spinning mechanism.

A single strand of hair caught on the dome shaft is enough to stall the LiDAR motor and trigger Error 1.
Wipe the transparent dome cover with a dry soft cloth to clean the surface.

Dust and fingerprints on the dome degrade the LiDAR readings. While this rarely triggers Error 1 directly, it helps maintain accurate navigation.
Power off the robot, wait 10 seconds, and power back on. Watch the dome as the robot starts — you should see it begin to spin within 10 seconds of startup.

If the dome visibly spins up normally and the error clears, an environmental factor (obstacle, tight space) caused the previous error.
If Error 1 persists after moving to an open area and cleaning the dome, check the Roborock app for a firmware update. Known LiDAR sensor firmware bugs have been fixed in several updates.

Open the Roborock app > Devices > your robot > Software Update. Install any pending update.

When to Call a Professional

If the LiDAR dome does not spin when the robot is on (you can see it rotating through the transparent dome cover), the LiDAR motor has likely failed. Contact Roborock support at roborock.com/support.

Frequently Asked Questions

Can I use my Roborock if the LiDAR is broken?

No. The LiDAR is the primary navigation system on Roborock robots. Without it, the robot cannot map, navigate, or avoid obstacles reliably. Running a Roborock with a broken LiDAR would result in it driving randomly, getting stuck, or potentially falling down stairs.

How long does the Roborock LiDAR motor last?

The LiDAR motor in Roborock robots is designed to last the life of the robot — typically 5+ years of daily use. Premature failure is rare and is usually caused by hair getting wound around the shaft. Regular cleaning of the dome shaft area prevents the most common cause of early LiDAR failure.
