Roborock Robot Vacuum Error 1 — LDS laser distance sensor blocked or stuck
Roborock Robot Vacuum · Error code Error 1
What Error 1 Means
The LiDAR (laser distance sensor) on top of the robot is jammed, blocked, or cannot spin freely. Without it the robot cannot map or navigate.
Symptoms
- Robot stops shortly after starting
- Voice prompt says 'LDS is blocked, please tap to release'
- App shows Error 1
- LiDAR turret does not spin
- No map being drawn
Common Causes
Long hair winds around the rotating turret and seizes it.
Buildup under the turret prevents free rotation.
Turret physically pinned by furniture edge.
A pressed bumper can also trigger LDS-related errors on some firmware.
Internal motor or PCB on the LiDAR module has failed.
How to Fix It
- Power off the robot using the switch under the lid.
- Manually spin the LiDAR turret with your finger — it should rotate freely with light resistance.
- Use tweezers to remove any hair, string, or fibers wound around the base of the turret.
- Blow out dust from the LDS base with compressed air; do not use liquids.
- Press the bumper several times to confirm it springs back fully.
- Move the robot to an open area (not under a couch) and restart.
- If the turret still won't spin, the LDS module needs replacement — contact Roborock support.
