What do Different Lights on Roomba Mean? (Pulsing Red/White)

Last updated on December 31st, 2023

You must have noticed the top of your Roomba emitting a light every now and then. For most models, the light is around the clean button, but for Roomba s series, the light is around the copper-colored circle on the top. You will notice not only different colors of light but also different patterns of the same color on the Roomba.

But what do different lights on Roomba mean? You might be surprised to know that each of those patterns and colors indicates other things. Let’s learn what our Roomba is trying to convey through the lights.

There are various colors of lights on Roomba, which mean distinct things for different models. For Roomba 600 to 900 series, red light means low battery and green means fully charged. For the Roomba i, j, and s series, white is for the battery, red is for errors, and blue is for Wi-Fi, virtual wall, and Dirt Detect.

Battery status lights on Roomba

A red color usually means your Roomba is very low on battery, and needs to be charged. Most Roombas automatically head back to the charging station when the red color flashes to recharge. But in rare cases, if the vacuum is not able to make it back to the dock because it ran out of battery, you have to manually place it for charging.

Make sure you know which series your model belongs to because different series show different lights while charging. It is rather easy to identify the battery status of a Roomba from the light it is showing. The table below will make it more clear for you.

  • Solid and flashing red colors tell you that your battery is extremely low and your vacuum cannot do any further cleaning before being charged.

  • Once the indicator light turns green, you can send your vacuum to clean again.

Why is there a red light on my Roomba?

A solid red light on Roomba 600 to 900 series models means that the vacuum is almost drained of all the battery, and it needs immediate charging. You should let the vacuum go to the docking station and charge enough to complete the cleaning cycle.

There are basically 3 colors in this series – white, red, and blue.

  • The white color will tell you everything you need to know about the battery status of your vacuum.
  • The red color indicates some kind of error with the Roomba. You can resolve the error by referring to the error code on the iRobot app. Or you can reboot your vacuum to make the error completely go away.
  • The blue color is more about connectivity. It will indicate the status of Wi-Fi, activation of Dirt Detect technology, detection of virtual wall barrier, etc.

Why is the red color on my Roomba not going away?

The red color on your Roomba won’t go away until you resolve the error. The solid red color on Roomba i, j, and s models usually indicates some kind of error. You have to press the ‘Clean’ button to get the exact details of the error. Roomba will either mention an error code or give a prompt like “Empty the bin.”

Alternatively, you can view the complete details about that particular error on your iRobot Home app. Solve the error, and the solid red light will automatically turn off.

Flashing blue color

One of the users was surprised to see their Roomba flashing a blue color quite often and didn’t know what to make of it. The flashing blue color is no sign of trouble. In fact, it’s good because you know your vacuum is running just fine. But there are several kinds of blue patterns like clockwise spin, counterclockwise spin, sweeping, etc. Make sure which blue pattern your Roomba is showing. Refer to the above table for exact details.

A flashing blue color indicates that the Dirt Detect technology on your Roomba has been activated. This technology identifies areas that have more dust than the others and gives more effort to clean those dirty spots. This technology can sense dirt particles with the help of dirt sensors on the base of the vacuum.

Conclusion

Now you have the complete means to interpret what each type of light on your Roomba indicates. Make sure you check the outline Roomba model number to know which series it belongs to before referring to the above-given tables. If your Roomba light won’t go off or the same type of light is on for an extended period, there might be some issues with the vacuum. In such cases, contact iRobot Customer Care Service for assistance.
