Knapp:When there is a problem with a Roomba robot vacuum, a red light will illuminate accompanied by an error code and error message. This "light code" tells you what's happening and what you can do to fix the problem.

If an iRobot Roomba has a problem, it will alert you with a red light. The light ring on the top of the robot vacuum may remain lit or start flashing.

The biggest difference between these light codes is the number: For example, you only get 11 error messages with the Roomba 800, with the extensive J series there are over 40. However, the numbers of these codes indicate the same problem. For example, on all Roomba series, error code 1 means the left wheel is stuck and/or Roomba is stuck.

Is an error code missing or can't find it? please send me a message,

Can you avoid error messages in the future?

As you have probably seen, many error codes have different causes. However, two main factors stand out. On the one hand, the environment seems to be the cause of an error message in many cases. Many error messages arise, for example, when the vacuum robot gets stuck or one of the wheels lands on a surface.

In addition, if the vacuum cleaner is poorly maintained, you can also expect a lot of error messages. For example, you will receive a series of error codes if a blockage can be found in the vacuum robot or if the parts do not (or no longer) connect properly.

To possibly avoid the error codes and error messages in the future, you can use the following tips:

  • Make sure the robot vacuum has time and space to get to know your home during installation.
  • Before activating Roomba, walk around the room and clean any items on the floor
  • Keep iRobot Roomba clean and clean it regularly

Curious about how to properly clean your robot vacuum cleaner and what goes into it? I've written a full guide on how to do thisCleaning Roomba.

In summary:When a Roomba issues an error message, a red light will illuminate. If you press the delete button or the bumper, you can hear what's happening, accompanied by an error code. The error code can help you figure out what you can do to fix the problem.
