Error 33 means your Roomba cannot complete cleaning and has cancelled its cleaning job.
- Ensure there were no changes to the environment during the cleaning cycle (i.e. closed door, moved furniture).
- It is possible for your Roomba to drive over transitions, such as doorway thresholds, that it cannot drive over again to leave the area. In this case, you may need to use Dual Mode Virtual Wall® Barriers to section off these areas to clean.
- Ensure the house has adequate light (daylight or dim lighting is sufficient) for your 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 or use Dual Mode Virtual Wall® Barriers to block off problem areas.
- Ensure the camera is clear of any dust or debris. 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.
If the message persists, perform a robot reboot by pressing and holding down the CLEAN button for 20 seconds.
