Error Code 1
Dreame Robot Vacuum
Severity:What Does This Error Mean?
Dreame Error Code 1 means the LiDAR sensor is blocked or cannot spin freely. Wipe the transparent LiDAR tower on top of the robot with a soft cloth, make sure nothing is obstructing its rotation, and restart.
Affected Models
- Dreame L10 Pro
- Dreame L20 Ultra

Common Causes
- Dust or debris on the LiDAR sensor window
- Sticker, tape, or packaging material blocking the sensor tower
- Debris preventing the LiDAR tower from rotating
- Hardware sensor failure — rare
How to Fix It
-
Turn the robot off.
Power off the Dreame robot before cleaning the sensor.
-
Locate and clean the LiDAR tower.
Find the cylindrical sensor tower on the top centre of the robot. Gently wipe its transparent window with a soft, dry microfiber cloth. Do not press hard — the sensor window can scratch.
-
Check the tower can rotate freely.
Gently try to rotate the LiDAR tower by hand — it should spin freely with minimal resistance. If it is stiff or stuck, check for a piece of debris, a sticker, or a hair wrapped around its base. Never force the tower.
-
Power on and test.
Turn the robot on. The LiDAR tower should begin spinning within a few seconds as the robot starts up. Press Clean and confirm Error 1 no longer appears.
-
Contact support if error persists.
If the LiDAR tower is clean and spins freely but Error 1 persists, the sensor itself may have failed. Contact Dreame support — the robot may be under warranty.
