Roomba Error 99 Causes
When your Roomba vacuum isn’t able to complete the cleaning job or mapping job due to an issue. The Roomba will automatically cancel the cleaning job.
The most common reasons the cleaning wasn’t able to complete and was cancelled include:
- The Roomba sensors are dirty, so it’s unable to navigate as it cleans or maps. It leads to confusion and the Roomba will stop and cancel the job.
- The Roomba was picked up and moved somewhere, so it’s confused about where it is. That leads to Roomba cancelling the job.
- There are too much clutter and obstacles in the ground, so the Roomba is unable to navigate its way through your home to clean. That causes Roomba to stop and cancel its current job.
- The Roomba is unable to find the dock station, so it will stop and give the error 99 message.
You’ll see the job as ‘cncl’ in the mission report to signify the job was cancelled.

Roomba Error 99 Fixes
To fix and avoid navigation and mapping issues in the future, try the following:
- Use a clean cloth or cotton swab to clean the navigation sensors on the bottom of the Roomba. If the deep sensor is dirty, the Roomba”s navigation system will be unable to map and navigate the floor to correctly clean.
- When the Roomba is moving around and cleaning, don’t pick it up. This will cause the Roomba to be confused about where it is. If you do move it in the middle of a job, put it back where it was or put it on the home base to reset.
- Clear the floors of excessive clutter, wires, and obstacles before the Roomba starts to clean. Alternatively, you can only let the Roomba clean areas that have no clutter. You can use Dual Mode Virtual Wall Barriers or Keep Out Zones to prevent the Roomba from going into the cluttered areas.
- Move the home base dock to a centralized location of your home. Put the Roomba on the dock and allow the Roomba to remap the home’s floor plant.
