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.
