Possible Causes
How to Fix / Troubleshooting
Safety first: Keep the robot on the floor while cleaning top sensors to avoid dropping it.
Steps to resolve:
- Clean top sensors: For models with a raised camera turret or top-facing sensor, gently wipe the lens/window with a soft, dry microfiber cloth.
- Improve lighting: Ensure rooms are moderately lit during mapping runs; very dark environments can cause navigation errors.
- Clear obstacles: Remove clutter, loose cords, and reflective objects from the floor during mapping.
- Reset map (if needed): In the iRobot HOME app, delete the existing map and allow the robot to create a new one.
- Update firmware: Check the app for updates and install them with the robot docked.
When to replace parts: If Error 15 continues after cleaning and remapping, the top camera/navigation sensor module may be defective.
