Roomba Error Codes: Light Codes & Its Meaning

When your Roomba robot vacuum malfunctions, a red light will flash along with an accompanying error code and message. This ‘light code’ allows you to pinpoint the issue at hand so that you can quickly work on resolving it.

Have you just heard your Roomba beep and received an error code you don’t know about? We are here to answer all your doubts, from what an error code is to how you can fix one.

Your Roomba robot vacuum cleaner may experience various issues; all these issues are neatly categorized by iRobot’s Roomba and are represented by error codes. 

These error codes include a plan of action in addition to classifying mistakes and describing them like charging errors, communication error, etc. So, if you run into a problem, you must continue as per the message and follow the instructions to fix it.

When it comes to showing the error codes, different models behave slightly differently: some only beep, while others say what the issue is. Thankfully, the error codes themselves are often the same across all models.

This complete guide is designed to help you troubleshoot your Roomba error codes and provide you with the best possible solution to resolve them.

How do I Find Out Which Error Code is Involved?

Roomba Series Error Codes: Causes & Solutions

Here, we have mentioned the common errors and their respective causes and fixes in a table below, which you can refer to troubleshoot the error code on your Roomba device.                 

Depending on the particular model, iRobot has modified certain error code styles in recent years.

From the Roomba i-series to the 800-series and J-series, each product line has its own set of specific error codes.

The Roomba 800 only displays 11 error messages, compared to the extensive J-series which has more than 40 different codes. Although their numbers may differ, these light codes generally denote a similar issue.

Although we’ve tried our utmost to compile each one of them in our guide, it’s a smart option to visit the iRobot website or contact irobot customer care for your particular model.

Use These Tips To Prevent Error Messages in Future

Preventing Roomba error messages

You can use the tips below to prevent future error codes and error messages.

  • Ensure that your robotic vacuum cleaner has adequate time and room to become familiar with its new environment during setup.
  • Before using Roomba, ensure that there are no objects on the floor.
  • Keep your Roomba vacuum cleaner clean and clean it regularly.

However, if you are facing some specific errors, you can refer to the instructions below:

The battery disconnected error frequently arises if your Roomba vacuum cannot detect the battery. Use an original iRobot Lithium-Ion battery if you want to avoid this issue. 

Also, see if anything is blocking the battery connection if you are using it and still seeing this warning.

You will get a Charging System Error if dirt interferes with the battery’s connection to the Roomba robot’s contacts. The problem should be fixed if the Home Base and Roomba robot’s charging connections are cleaned.

If you position your Roomba near a heating vent, furnace, or anything else that generates heat, the error “Battery is too warm” will frequently occur. Charging your Roomba cleaner at room temperature can avoid this issue in the future.

Roomba can show Communication Error if the battery is low or drained out. To avoid this issue, use original and compatible lithium ion batteries.

If the battery in the Roomba cleaner begins to malfunction, the Lithium-Ion Battery Error is shown. Depending on the particular model, this message may differ. If you see this error notice, you should contact iRobot customer service right away.


If there is an error with iRobot Roomba, it will communicate with red light and make a two-tone sound, followed by many beeps, or by speaking in a voice called error codes. You can replay the error code by pushing the bumper or the ‘CLEAN’ button at the base.

Your Roomba should continue to function properly for many years if you consistently respond to any error codes it may display. To prevent error codes from appearing, you should maintain & clean your Roomba once a week.

Frequently Asked Questions

What do the symbols on my Roomba mean?

The different symbols on your Roomba indicate the status of your robot. The three main indicators are a triangle, an exclamation mark, and two arrows.

  • The triangle symbol is a reminder that you should empty the bin after each cleaning cycle. This symbol will light up when the dustbin needs to be emptied.
  • The exclamation mark symbol indicates an error or problem with the Roomba. If this symbol appears, you should check the manual to troubleshoot the issue.
  • The two arrows indicate when your Roomba is in cleaning mode. The left arrow shows that it’s currently in Vacuum Mode, while the right arrow shows that it’s in Spot Clean Mode.

In addition, other symbols may appear on your Roomba, such as an X is a battery indicator and shows when you need to recharge the battery, or a spinning circle when it is currently cleaning.

How do I fix my Roomba bin error?

If your Roomba is displaying a bin error, then the dustbin needs to be emptied. To do this,

  • Press and hold the CLEAN button until you hear a beep.
  • Then, open up the dustbin lid and pull out the filter.
  • Empty it into a trash can, replace it in the robot, close the lid, and press the CLEAN button again.
