Error forty-two (42) means that your Roomba® failed to re-localize during a direct cleaning job using Smart Maps, and the map may also appear to not look correct in the app.
Your robot's headlight on the front-facing camera is designed to help your robot avoid obstacles and dock, but the headlight does not produce enough light for the robot to navigate correctly in the dark. Ensure the house has adequate light (daylight or dim lighting should be sufficient) for Roomba® to navigate correctly. Extremely dark rooms could obscure the iAdapt® localization camera and cause problems with navigation and coverage.
Reasons why the error may occur:
- Changes to the environment during the cleaning cycle (i.e., closed door, moved furniture)
- It is possible for Roomba® to drive over transitions, such as doorway thresholds, that it cannot drive over again to leave the area
- Not enough adequate lighting (daylight or dim lighting is sufficient) for Roomba® to navigate. Extremely dark rooms could obscure the iAdapt® localization camera and cause problems with navigation and coverage.
- Excessive clutter could contribute to this error. Clear cluttered areas.
- The camera is covered with dust or debris. If so, wipe the clear window on the top surface using a microfiber or soft cotton cloth that has been lightly dampened with water or a screen cleaning solution
- Roomba® was picked up and moved to another location while cleaning
Please ensure there were no changes or edits to your Smart Map. Place your Roomba® back onto the Home Base® and attempt another direct cleaning job.
If the message persists, try moving your Home Base to a different location and start Roomba from the Home Base®. Environmental interference may prevent Roomba® from navigating as expected. If navigation does not improve, please contact iRobot Customer Care.
