General Troubleshooting Steps

Before diving into specific errors, try these universal fixes:

1. Restart the Robot Power off for 30 seconds, then restart. Clears temporary software glitches.

2. Clean All Sensors Use microfiber cloth on cliff sensors, LiDAR, cameras, and charging contacts.

3. Check for Firmware Updates Manufacturers often fix bugs via app-based updates. Check your robot's app.

4. Verify WiFi Connection Most robots require 2.4GHz WiFi. 5GHz networks are not compatible.

5. Clear Obstructions Remove hair from brushes, empty bin, check wheels for debris wrapped around axles.

When to Contact Support

Warranty Considerations

Opening your robot's casing or attempting hardware repairs may void your warranty. Contact manufacturer support first for:

Motor failures or burning smells
Battery not holding charge after 1 year
Persistent error codes after troubleshooting
Damage from manufacturing defects
Software bugs preventing basic operation

Document Everything: Take photos of errors, note error codes, and keep records of troubleshooting steps attempted.

Preventive Maintenance

Most robot issues are preventable with regular maintenance:

Weekly: Empty dustbin, wipe sensors, check for hair tangles on brushes
Monthly: Clean HEPA filter (if washable), deep-clean charging contacts, inspect wheels
Quarterly: Replace filter (if non-washable), check battery health, update firmware
Annually: Replace side brushes, main roller brush, and check for worn wheels
