Quick answers
What is wrong?
Hair or debris catches a drive wheel so the robot struggles to move or reports a wheel error.
What you might notice
- Wheel / drive-wheel alert
- Struggles to move or turns oddly
- Wheel does not spring back
Can I fix this myself?
Often yes with careful cleaning. Difficulty: easy · about 5-15 min. If unsure or it returns, use mail-in repair.
What you need
- Soft cloth
- Cleaning tool or tweezers
Do this
- Power off and flip the robot.
- Clear hair/debris from both main wheels and axles. Press each wheel down — it should spring back; spin by hand.
- Clean the front caster / omnidirectional wheel the same way.
- Place on a clear dry floor and restart. If the alert returns, request wheel-module repair.
Parts (only if cleaning fails)
- Drive wheel assembly (service)
