Is your Roomba displaying Error 15 and disrupting your cleaning schedule? This error can be frustrating, but understanding its causes and knowing how to troubleshoot it can get your robotic vacuum back on track. This article provides a comprehensive guide to resolving Roomba Error 15, ensuring your home cleaning remains efficient and hassle-free.
What Does Roomba Error 15 Mean?

Roomba Error 15 generally indicates an internal error within the robot. According to iRobot, it means your Roomba experienced an internal error and was able to take care of itself, and is letting you know about it afterward. This can sometimes be a temporary glitch, but if it occurs frequently, it needs attention. While in some instances, iRobot says you don’t have to perform any troubleshooting, frequent occurrences of Error 15 can interfere with the Roomba’s ability to clean.
Common Causes of Roomba Error 15
While Error 15 points to a general internal fault, some factors can trigger it:
- Software Issues: Glitches in the Roomba’s software can lead to this error.
- Mapping Problems: Issues with the Roomba’s smart map, especially after software updates, can cause Error 15.
- Low Battery: A low or faulty battery can sometimes trigger the error.
- Internal Communication Error: A communication problem between the Roomba’s internal components can also cause this error.
- Wheel Motor Issues: In some Roomba models, Error 15 can indicate a problem with the wheel motor.

Here’s a step-by-step guide to troubleshooting Roomba Error 15:
- Reboot Your Roomba: A simple reboot can often resolve temporary software glitches.
