Robot vacuum drifts to one side or does not move in straight lines.

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

Unequal wear on drive wheels, Debris in one wheel gearbox, Faulty wheel encoder on one side, Weak drive motor on one side

Safety first: Turn off the robot before inspecting wheels.

Clean wheels: Remove debris from both drive wheels and ensure they rotate freely.
Check tire wear: Compare the rubber treads on both wheels. If one is significantly more worn, replace the drive wheel assembly.
Test on open floor: Run the robot on a large, flat area and observe its path. If it consistently veers, the slower side’s motor or encoder may be faulty.
Service if needed: Replacing the affected drive motor assembly is typically required to correct persistent drift.
