Though, life isn’t quite this straightforward. Along the way, you might come across some additional battery requirements.

How Long Does Roomba Take To Charge?

The battery of a recently purchased Roomba is only half charged. If you use your brand-new Roomba, it might stop cleaning in the middle of the session if it isn’t charged.

All Roomba models, including those in the 600 and s9 series, are covered by this. The typical battery life of a Roomba is 400 charge cycles or two to four years. Your Roomba may take longer than two hours to fully recharge itself over time.

We don’t want to stop at just providing you with this little nugget of knowledge. Instead, we’ll provide you with some maintenance tips for your Roomba. In addition, we’ll respond to some of the most typical inquiries people have about batteries.

How Can I Tell When My Roomba Is Fully Charged?

Indicator lights on the Roomba can be used to check the status of its charging. Most Roombas use the following light colors to indicate battery level:

  • Green or white if the Roomba is fully charged
  • Amber pulsing if the Roomba is still charging
  • Amber pulsing or red if the battery is very low or empty

The light may or may not be visible while Roomba is charging, depending on the model. By pressing the clean button once, you can always check the battery’s condition. The indicator light will display charging status as a result of this.

You can also check the battery level in the iRobot HOME app for Roombas that are more recent. As soon as the app is opened, the top-right corner of the screen will display a battery indicator icon.

What To Do If Roomba Is Charging Slowly

Roomba will always require at least two hours to charge, but you can prevent it from taking longer. If it takes more than two to three hours to fully charge, there may be a problem with the outlet, charging dock, charging contacts, or Roomba battery.

The most frequent reason for a slow-charging Roomba is dirt on the charging contacts. At the very least once a month, you should clean the charging base with a microfiber cloth, paying close attention to keeping the charging contacts free of debris.

Even after cleaning the contacts, the battery might need to be changed if your Roomba still takes a while to charge. Buy a battery pack that is appropriate for your Roomba model. With the Roomba 600, 800, and 900 series, this one is compatible. The i-series and e-series Roombas can both use this one.
