Safety first: Turn off the robot and keep it on a stable surface.

Locate LDS turret: On mapping-capable Neabot models, the LDS is usually a raised circular turret on top of the robot.
Clean LDS window: Wipe the transparent window or ring on the turret with a soft, dry microfiber cloth to remove dust and fingerprints.
Check turret rotation: Gently try to rotate the turret. It should move freely with slight resistance. If it feels stuck, inspect for foreign objects wedged around the base.
Power-on test: Turn the robot on and listen for a faint spinning sound from the LDS. If there is no sound and E10 persists, the LDS motor or sensor may have failed.
Service or replace: LDS modules are delicate; if cleaning and freeing the turret do not resolve the error, the LDS assembly or mainboard should be replaced by a qualified technician.

Warning: Do not open the LDS module or look directly into the laser; although low power, direct exposure is not recommended.

Robot vacuum shows E10 and refuses to start; often described as a laser sensor or LDS error on mapping models.
