How Long Do Roomba Batteries Last?


If you have a robot vacuum at home, how long do Roomba batteries last? They generally last between two and 2.5 hours, and a number of factors play a role.

If you are looking for a Roomba, you need to find one that can adequately clean your house. This means the battery has to last long enough to get your Roomba to clean every room and then return to the docking station. In general, Roomba batteries last about two hours, but there are a number of factors that can significantly impact the life of your battery.

Your Roomba Model’s Features 

First, you need to take a look at the features that come with your Roomba. Robot vacuums have come a long way, and there is a good chance that your Rooba has a lot of special features. For example, your Roomba might have built-in cameras, a mop attachment, and even advanced LiDAR navigation. 

Even though all of these features are impressive, they also require power. Therefore, the more advanced features your Roomba has, the faster the battery life will drain. 

Various Cleaning Modes

You should also look at the cleaning modes that come with your robot vacuum. For example, many robot vacuums know that they have to increase the suction power when they go over the carpet. Even though it is nice to have a robot vacuum that can handle carpets, this can also drain the battery more quickly. If your robot vacuum has to ramp up the power every time it crosses an area rug or a carpet, the battery is going to drain faster.

How Well You Take Care of the Roomba

How well you take care of the Roomba will also impact how long the battery lasts. For example, if you don’t clean the brush regularly, the hair and fur will get trapped. This means that your robot vacuum may have to turn up the selection to clean up routine dirt piles around the home.

Furthermore, if you do not take care of the wheels, your robot vacuum has a higher chance of getting stuck. Your robot vacuum may have to use a lot of extra power to get unstuck, shortening the battery life. 

Final Word on How Long Do Roomba Batteries Last

Even though you should expect your Roomba to have a battery life of about two hours, it depends not only on the type of vacuum you buy but also on certain factors around the home. If your home has a lot of carpets, your robot vacuum will have to work harder to clean it, shortening the battery life. You also need to clean the Roomba regularly if you want the batteries to last as long as possible. Think about how long it takes the robot vacuum to clean your home and make sure you purchase a Roomba that has enough battery life to do the job.
