Error 19 Irobot: Troubleshooting Guide


iRobot is a well-known brand in the market of robotic vacuum cleaners. Their products are designed to make cleaning tasks easier and more efficient for households. However, like any other electronic device, iRobot can also encounter errors and malfunctions. One of the most common errors that users face is error 19.

What is Error 19?

Error 19 is a common technical issue that users encounter while using iRobot. This error usually occurs when the robot vacuum cleaner’s sensors are unable to recognize the environment properly. In other words, it means that the sensors are not working correctly, and the robot cannot navigate or move around the room.

Reasons for Error 19

There are several reasons why your iRobot may encounter error 19. Some of the most common reasons include:

Dirty Sensors

The sensors on your iRobot’s body and wheels can accumulate dust and debris over time, which can affect their performance. If the sensors are dirty, they may not be able to pick up signals from the environment correctly, thus causing error 19.

Obstacles in the Path

Another reason why your iRobot may encounter error 19 is due to obstacles in its path. If your robot vacuum cleaner encounters an obstacle that it cannot navigate around, it may trigger error 19.

Low Battery

If your iRobot’s battery is low, it may not function correctly. A low battery can cause your robot to malfunction and trigger error 19.

How to Fix Error 19

If you encounter error 19 while using your iRobot, there are several ways to fix it. Here are some of the most effective ways to troubleshoot error 19:

Clean the Sensors

Cleaning the sensors on your iRobot is the first step to troubleshoot error 19. You can use a soft-bristled brush or a microfiber cloth to remove any dust or debris that may have accumulated on the sensors.

Clear the Path of Obstacles

If your iRobot is encountering obstacles in its path, you can clear the path to allow it to move freely. Remove any clutter or objects that may be blocking the robot’s path.

Charge the Battery

If your iRobot’s battery is low, you need to recharge it before you can use it again. Plug the robot into its charging dock and wait for it to charge fully.

Reset the Robot

If none of the above methods work, you can try resetting your iRobot. You can do this by holding down the Clean button for 20 seconds until you hear a beep. This will reset the robot’s sensors and may fix the error.


Error 19 is a common issue that iRobot users encounter. However, it is not a significant problem and can be fixed easily. By following the troubleshooting guide above, you can fix error 19 and get your iRobot back to functioning correctly. Remember to keep your sensors clean, clear the path of obstacles, charge the battery, and reset the robot if necessary.
