Complete Roomba Error Code Guide (Error 7, 25 & more)

Last updated on September 20th, 2023

When your Roomba encounters a problem, it uses a combination of lights and sounds to address the issue. A shining red light can be observed on the Roomba’s body that indicates an error, and by pressing the Clean button you can hear the specific problem it is facing.

This is usually followed by an error code. In this article, we will discuss all the error code types that are encountered on various Roomba models. Keep on reading below.

What are the common Roomba error codes?

Error 7, Error 19, and Error 25 are some of the most common error codes faced by Roombas. Error 7 means that the robot’s battery is low, error 19 shows that the bot has lost connection with the docking base, and error 25 signifies an internal circuit error.

How to find which Roomba error code is involved?

Different error messages displayed by Roomba

The Roomba contains a tiny speaker through which it tells the error message. To hear the error message, you have to press the Clean button, and the Roomba will tell you the error. By pressing the clean button again you can re-hear the error if you missed the initial letter or need to confirm the error details before taking any action.

Another way to hear the message is by pressing the front bumper that replays the error message, without interrupting the Roomba’s operation.

Whereas, if your Roomba shines blue light it means everything is fine, and no issue is detected. Here we have an error code table, which will help you to know about them and help to fix them.

Complete Roomba error codes

Note: The above table gives the complete list of error codes that occur in different Roomba models. So some might not occur in your robot.

Preventive measures to minimize these errors

To prevent future error codes and error messages with your Roomba vacuum cleaner, here are some essential tips to keep in mind:

  1. Clear the Floor: Before activating Roomba, take a quick walk around the room and clear any objects or obstacles from the floor. This helps to prevent the vacuum cleaner from getting stuck or encountering surface irregularities during its cleaning process.
  2. Allow Sufficient Setup Time: When setting up your robotic vacuum cleaner, give it enough time and space to familiarize itself with the new environment. This allows the Roomba to create an accurate map of the surroundings, resulting in smoother cleaning sessions.
  3. Regular Cleaning Routine: Keep your Roomba vacuum cleaner clean by following a regular maintenance routine. Empty the dust bin after each cleaning session and clean the brushes, wheels, and sensors to remove any debris or blockages. This ensures optimal performance and reduces the chances of errors caused by clogged components.
  4. Follow Manufacturer’s Guidelines: It is essential to follow the manufacturer’s guidelines for maintenance tasks such as filter replacement and general upkeep. These guidelines are designed to keep your Roomba in optimal condition and minimize the occurrence of errors.

Solving some common errors

Now, let’s address some specific error messages and how to handle them:

  • Battery Disconnected Error: If you frequently encounter this error, make sure you are using an original iRobot Lithium-Ion battery. Check the battery connection for any obstructions or loose connections.
  • The battery is too Warm Error: Avoid placing your Roomba near heat sources such as heating vents or furnaces. Charging the vacuum cleaner at room temperature can help prevent overheating and this specific error message.
  • Charging System Error: To resolve this error, clean the charging connections on both the Roomba robot and the Home Base. Make sure there is no dirt or debris interfering with the battery’s connection.

By incorporating these tips, you can proactively prevent most errors from occurring. However, in the event that you encounter an error during the operation of your Roomba, you can refer to the table above for the specific error code and its corresponding troubleshooting steps.

What do the LED Light and Beep Patterns Mean?

In older versions of Roomba, such as the 600, 800, and 900 series, you can determine error codes by observing the LED light and beep patterns. Each specific beep or LED blink corresponds to a particular error code, which helps users identify the issues that their Roomba might be experiencing. These indicators serve as a useful troubleshooting tool to diagnose problems with the robot.

Here’s a completed version of the table for the Roomba error codes, LED light patterns, beep patterns, meanings, and troubleshooting steps:

Whenever Roomba runs into any error, it notifies you by blinking an LED which is present on its body. By following the pattern of blinking, you can deduce the error the Roomba is facing. You can also view the error on the iRobot app and take action accordingly.
