Robot announces E18 and may not start cleaning or may stop near obstacles

Safety: Turn the robot OFF.

• Remove front caster: Flip the robot over. Pull the front caster wheel straight up to remove it from its socket.
• Clean wheel and axle: Remove hair and debris from around the wheel and the axle. Ensure the wheel spins freely.
• Clean socket: Remove any debris from the caster socket in the robot.
• Reinstall: Push the caster back into place until it clicks and rotates freely.
• Test: Power on the robot and start a cleaning cycle.

If E18 persists and the wheel does not spin freely, replace the front caster assembly.
