How to Check Roomba Battery Level? (2 Methods)

Last updated on December 31st, 2023

Roombas truly give a hands-free cleaning experience. But sometimes, you might want to check the battery level of your vacuum. Maybe you are trying to decide whether you should let it out for a quick clean or charge it more. In any case, if you want to know the current battery level of your Roomba, there are a few ways in which you can do it. Let’s check them all out in this article.

So how to check Roomba battery level?

You can check the Roomba battery level from the indicator lights on the vacuum or from the iRobot Home app. Press the ‘Clean’ button on the robot to check the current battery status, or look at the top right corner of the main page of the iRobot Home app. The app also gives a battery status message on top of the ‘Clean’ button.

Check Roomba battery level

There are two ways in which you can check the battery level on your Roomba:

  • From the indicator lights
  • From the iRobot Home app

Both these are simple to follow methods. It doesn’t matter which method you choose because you will get the live update of your battery status anyway.

  • If you are near the vacuum, you can choose to view the indicator lights.
  • If you are away from home or the Roomba is in another room, then you can save the trouble and just check on the iRobot app.

Now let’s discuss both ways of checking the battery level of your Roomba.

With indicator lights

You can know your Roomba’s battery status from the indicator lights on the robot. These lights are usually around the ‘Clean’ button. But for Roomba s series, it is around the top lid of the vacuum.

  • On some Roomba models, indicator lights keep glowing. You can just look at the color they are showing.
  • For other models, you have to press the ‘Clean’ button once on the robot. On pressing the button, Roomba will emit a particular color light; from that, you can know the battery status.

Note: Various colors and patterns of lights indicate the different status of the battery.

As the indicator lights tell the battery level on your Roomba, it is important to understand which color and which pattern signifies what. In the following table, locate the series of the Roomba you own and check what different colors and patterns indicate in front of it.

From the above table, it is clear that:

  • Roomba 500 to 900 series uses a Solid Green light to indicate vacuum is completely charged. But that changed with the Roomba i series.
  • In the Roomba i, j, and s series, a Solid white light indicates the completion of charging.

From the iRobot Home app

To check the battery level from the iRobot Home app, open the app on your phone. On the app’s main screen, you will notice a large ‘Clean’ button. You will notice the battery indicator icon on the top right corner of the screen. The green bar on the icon will tell the current level of the battery. This will show the exact amount of battery on your Roomba.

Alternatively, there’s a message written above the ‘Clean’ button on the same screen. The message could be “Ready to clean. Charging” or “Ready to clean. Fully charged.” You can deduct from these messages the level of battery on your Roomba.

  • “Ready to clean. Charging” – Roomba is not completely charged yet but has enough battery to start a cleaning cycle. You will get a shorter cycle as the battery is not full.
  • “Ready to clean. Fully charged” – Roomba battery is completely charged, and you can start the cleaning cycle without any worry.

How Roomba tells the battery level is low?

If you ever see a red light on your Roomba, it could indicate your battery is low. Different series show different patterns of the red light, so first check which series your Roomba belongs to. The following indications for those particular series tell you that the Roomba’s battery is low:

  • Roomba 500 to 900 series – Solid red
  • Roomba i, j, and s series – Pulsing red

This indicator light will turn off once your vacuum is charging. But if it persists, there could be some issues with your Roomba. In the next section, we have highlighted all the major issues encountered with a Roomba’s battery. If you are not able to make the red light go away, then don’t hesitate to contact iRobot Customer Care. They will provide the most appropriate solution or a replacement if you are still under warranty.

Problems faced with Roomba battery level

Some of the common problems faced while viewing the Roomba battery level are:

  • The battery indicator is not reaching full when charging
  • Roomba’s battery level is not increasing (Roomba is not charging)

There is this common issue with Roombas that sometimes their battery indicator doesn’t show it is fully charged, no matter what. You might charge your Roomba for a long time, but the battery level doesn’t change. There’s nothing to worry about if this is happening to you because there are simple solutions to this issue. By employing the below-addressed solutions, you can resolve this issue with ease.

Solutions to battery-level problems

The battery status of Roomba is updated at certain time intervals on the app. If you think your battery status is not updating, wait for 15 minutes and then reopen the app. If the status doesn’t change even after a long time, then use one or more of the below solutions.

Ensure proper network connection

The battery status is updated on the app only when it is connected to the same Wi-Fi network as the robot. If you are connected to any other Wi-Fi network, or you are away from your home, the battery update will not be reflected on your app. To check the correct battery status, make sure you and the robot are connected to the same Wi-Fi network.

Check Roomba’s alignment on the charging station

Sometimes, a Roomba doesn’t align correctly with its charging station, and this charging doesn’t take place. It is obvious that if the vacuum is not charging, the charging indicator won’t be full. So, if you are connected to the local network, and still the app doesn’t update the battery status check the alignment of the vacuum on the dock. If it is incorrectly aligned, then simply align it properly.

Clean charging contacts

The battery indicator not reaching full could also be associated with dirty charging contacts. Debris builds on the charging contacts in the robot as well the charging station. And they hinder the charging process.

  • You have to clean them with a damp cloth or melamine foam, such as a Magic Eraser, to clear all the debris.
  • Ensure they are shiny and not rusted.
  • Cleaning the charging contacts should resume the charging, and this updates the battery indicator.

Even after using all these solutions, if the problem with the battery persists then contact iRobot Customer Care for help.

Does the Roomba light stay on when charging?

Yes, the Roomba light stays on in some models, but in others, it turns off after a few seconds. It really depends on the model of Roomba you have. If your Roomba light is on when it is docked, it could probably be because it is charging. To know whether the indicator light on your Roomba should stay on during charging, refer to the table below.

Roomba modelsLight when charging
Roomba 500 seriesPulses after 4 secs
Roomba 600 seriesPulses after 4 secs
Roomba 700 seriesStays on for 60 seconds, then turns off
Roomba 800 seriesStays on for 60 seconds, then turns off
Roomba 900 seriesStays on for 60 seconds, then turns off
Roomba s seriesStays off
Roomba i3 and i1Stays off
Roomba i7Stays on
Which Roomba lights stay on during charging

From the table, it is clear that the old Roomba series was used to keep the indicator lights on. But Roomba has adopted the power-saving method now.

To avoid unnecessary use of power, new Roombas keep their indicator lights off while charging.

They will, however, turn on for a few seconds when you press the ‘Clean’ button.

Conclusion

As discussed in this article, you can either interpret the indicator lights on your robot or check the exact status on the iRobot Home app to know the battery level of your Roomba. Both methods are easy to employ. There are a few issues reported with the app battery status, but if you employ the provided solutions, you shouldn’t face any problems.
