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

Dirty front IR sensors, Bumper switches not triggering, Bumper travel limited by debris, Faulty obstacle sensor board

Safety: Turn OFF the robot.

Clean front sensors: Wipe the front IR sensor windows with a soft, dry cloth.
