Roborock Navigation Alignment or Sensor Drift

Robot vacuum drifts off straight lines, curves unexpectedly, or maps rooms with distorted shapes.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

LDS window dirty, Wheel encoder slippage, IMU calibration drift, One drive wheel worn more than the other

Safety first: Turn off the robot before cleaning sensors.

Step-by-step:

Clean LDS and sensors: Wipe the LDS turret window and underside cliff sensors with a soft cloth.
Inspect wheels: Check both drive wheels for equal wear and proper inflation (solid wheels) and remove any debris.
Remap home: Delete the existing map and perform a full cleaning run to create a new map.

If navigation remains erratic, the wheel encoders or IMU may be faulty, requiring replacement of the wheel module or main board.
