Robot vacuum squeaks or chirps when the wheels move.

Safety: Turn off and flip the robot over.

• Clean wheel area: Use a soft brush to remove dust from around the drive wheels and front caster.
• Check caster wheel: Pop out the front caster wheel (if removable), clean the axle and socket, and reinstall.
• Avoid oil: Do not use oil-based lubricants; if necessary, a tiny amount of dry PTFE lubricant can be applied to the caster axle only, avoiding sensors and belts.
• If squeak persists from drive wheels: The wheel modules may need replacement.
