Possible Causes

LDS turret blocked by debris, LDS turret stuck due to hair or dust, LDS window dirty or covered, Robot wedged in tight space affecting LDS rotation

How to Fix / Troubleshooting

Safety first: Turn the robot off using the power switch (if present) or hold the power/clean button until it shuts down. Remove the robot from the charging dock before working on it.

Step-by-step:

  • Relocate the robot: Pick up the robot and place it in an open area away from tight corners, under furniture edges, or reflective glass walls. Restart the robot and try a spot clean.
  • Inspect the LDS turret: On most Roborock models (S5, S6, S7, S8, Q series, etc.), the round turret on top houses the laser. Check that it can rotate freely by gently nudging it. It should spin smoothly without grinding or sticking.
  • Clean the LDS window: Use a soft, dry microfiber cloth to wipe the transparent window around the turret. Do not use water or solvents directly on the turret.
  • Remove debris around turret: Check the gap between the turret and the top cover for hair, threads, or dust buildup. Use tweezers or a soft brush to remove any obstruction.
  • Reboot the robot: Power the robot off for 30–60 seconds, then power it back on. Start a cleaning cycle from the app or the physical button.

If the error persists: The LDS motor or sensor may be failing. Avoid disassembling the turret unless you are experienced; contact Roborock support or a qualified technician for LDS module replacement.
