How Many Years Does a Roomba Battery Last?

The iRobot Roomba is a super popular home vacuum cleaner – but how many years does a Roomba battery last before it needs to be replaced?

When taken care of properly, a Roomba battery should last 2-3 years before it needs to be replaced. The latest Roomba vacuums come with high-performing lithium-ion batteries, designed to be durable and long-lasting, so your battery should last several years without issue.

Find out what you need to know about your Roomba battery and tips on how to look after it properly.

1. How to Look After a Roomba Battery?

As is the case with all applications, the durability of your Roomba battery depends on how well you look after it. Therefore, to ensure that your Roomba battery lasts 2-3 years, you should make sure of the following:

  • Charge your Roomba at room temperature and keep the vacuum away from direct sunlight.
  • Thoroughly clean your Roomba and remove any hair or debris. Using the device when it’s dirty will add more strain to the battery.
  • Following each use, recharge the battery as soon as you can. When not in use, keep the Roomba plugged in and set to Home Base.
  • Fully charge the battery at least once every six months for optimal performance.
  • If you’re not planning to use the Roomba for two weeks or more, place it in Sleep Mode to preserve the battery.

These simple tips will help you look after your Roomba battery and ensure that it doesn’t need to be replaced. Should you care for your device, your battery will last 2-3 years without any significant issues.

2. How Do I Know if My Roomba Needs a New Battery?

You should be able to use a Roomba for at least fifty minutes on a full charge. If the vacuum dies after 10-30 minutes, it’s a sign that the battery is on its way out.

What’s more, if the battery is slow in charging when connected to power, it’s another sign that it could be time to replace the battery.

Roombas have an excellent reputation for the speed at which they charge, so you should consider your options if the device is slow to reach full battery capacity.

Of course, another sign is the age of the battery itself. We’ve mentioned that Roomba batteries typically last for 2-3 years without needing to be replaced.

So, if your device reaches the 2-3 year mark and you notice that the battery isn’t performing as well as it once did, it could be time to find a replacement.

3. How to Replace a Roomba Battery?

If you’ve decided to replace a Roomba battery, you can order a replacement directly from the manufacturer. Remember, there are several different batteries, depending on the make and model of your Roomba, so you need to make sure you order the correct battery for your application. 

Once ordered, replacing the battery on your Roomba device is really easy. 

Unscrew the panel on the back of the vacuum by loosening the screws before unclipping the battery from the relevant section.

You can insert the replacement battery, and the tab will secure it. 

Screw the panel back on, and you’re all set. You might need to place the Roomba back onto its Home Base to wake it up, as some batteries disconnect after a period of inactivity.

4. How Much is a Replacement Roomba Battery?

You can order a replacement Roomba battery directly from the manufacturer or a third-party store like Walmart. The replacement battery’s cost depends on your device’s model number.

At the time of writing, a replacement Lithium Ion battery for the Roomba e and iSeries is $89.99 from the manufacturer.

However, you can find slightly cheaper options elsewhere, even though it always makes sense to purchase a replacement directly from the manufacturer to save any compatibility issues.

Granted, a replacement lithium-ion battery for a Roomba is undoubtedly costly.

Still, given that the initial battery should last 2-3 years, you can wait to replace the battery until you have used the application for a considerable time.

5. Do iRobot Roombas Come with a Warranty?

When you purchase an iRobot Roomba from the manufacturer, your purchase is covered by a lifetime warranty, which protects you should your Roomba become defective at any point after purchasing it.

However, you should be aware that general maintenance of the item is not included in the warranty, meaning that the replacement of the battery and brushes, for instance, are not covered by the warranty.

Therefore, while it’s good to know that a warranty covers your Roomba to protect you should your device malfunction or be defective, you need to cover the cost of a replacement battery yourself.

Conclusion

If you look after it correctly, your iRobot Roomba battery should last 2-3 years before it needs to be replaced.

When the time comes, you can order a replacement lithium-ion battery directly from the manufacturer, saving you any issues regarding durability or compatibility.
