Are you considering getting a robotic vacuum cleaner? Chances are you’ve heard of the Roomba and are curious about how long it takes to charge. Well, you’ve come to the right place! In this blog post, we’ll be exploring how long it takes for a Roomba to charge and how you can speed up the process.

How Long Does it Take for a Roomba to Charge?

Introduction to Roomba

The Roomba is an autonomous robotic vacuum cleaner developed by iRobot. It was first introduced in 2002 and has since become one of the most popular robotic vacuum cleaners on the market. The Roomba uses a variety of sensors to navigate around a room and detect obstacles. It also has a self-charging feature, which allows it to return to its charging station when its battery is low.

How Long Does it Take to Charge a Roomba?

The amount of time it takes for a Roomba to charge depends on the model and the type of charger being used. Generally, it takes between two and four hours for a Roomba to charge completely. This means that you can expect your Roomba to be fully charged and ready to go in a few hours.

Different Roomba Models and Charging Times

There are several different models of Roomba, and the charging time varies depending on the model. The Roomba 600 series, for example, takes around two hours to charge while the Roomba 900 series takes around four hours. Some of the newer models, such as the Roomba i7 and s9, can even charge in as little as one hour.

How to Speed Up the Roomba Charging Process

If you’re in a rush and need your Roomba to charge quickly, there are a few things you can do to speed up the process. One way is to use a higher amp power supply to charge the Roomba. This will increase the charging rate and reduce the charging time. Another way is to reduce the amount of suction power the Roomba uses while cleaning. This will reduce the amount of power the Roomba consumes, allowing it to charge faster.

Troubleshooting Roomba Charging Problems

If your Roomba is not charging properly, there are a few things you can try. First, make sure the power supply is plugged in and the charging contacts are clean and secure. If the charging contacts are dirty, you can use a cotton swab to gently clean them. You should also check the charging station to make sure it is working properly.

Roomba Charging Safety Tips

When charging your Roomba, it is important to take safety precautions. Make sure the power supply is securely plugged into a grounded outlet and never leave the Roomba unattended while it is charging. You should also never use a damaged power supply or charging station.


Now that you know how long it takes for a Roomba to charge, you’ll be able to plan your cleaning schedule accordingly. You can even speed up the charging process by using a higher amp power supply and reducing the suction power while cleaning. Finally, it’s important to take safety precautions when charging your Roomba to ensure its longevity.
