DEEBOT LDS error (laser sensor stuck)
DIRECT ANSWER
COMMON CAUSES · RANKED
Turret jammed by hair or debris MOST COMMON
Hair and dust work into the gap around the spinning turret until its little motor can't turn it — ECOVACS' own first check is whether the assembly rotates when flicked.
Robot wedged under furniture mid-scan
A turret pressed against a sofa frame reads as an LDS fault — free the robot and restart before suspecting hardware.
Dusty laser window
A film of dust over the turret's window blinds the laser even while it spins — a dry microfiber wipe restores the view.
Worn LDS motor or belt RARE
A turret that stalls repeatedly with nothing wrapped around it is wearing out inside — a repair-or-support case rather than a cleaning one.
HOW TO FIX IT
Power off and inspect the turret
Switch the robot off and look at the raised laser turret for wrapped hair or wedged debris.
Flick-test the rotation
Gently spin the LDS assembly with a finger — ECOVACS' official check. It should turn freely with no gritty resistance.
Clean the gap and the window
Pull out visible hair and wipe the turret's window and surrounding gap with a dry microfiber cloth.
Restart — on the dock for DToF models
Power the robot back on and start a clean; for newer DToF models (X2 era), ECOVACS' official fix is restarting the robot while it sits on the dock.
Escalate a repeat fault
If the alert returns on every run with a clean, free-spinning turret, contact ECOVACS support — the LDS module itself may need service.
