Roomba batteries are designed to work with short charge times and high discharge rates. This means, once your battery has been charged for the first time, the normal charging time should be about two hours. Life isn’t quite as simple as this, though. There are a few other battery needs you may discover along the way.
Charge your Roomba battery overnight before using it for the first time. This initial charge provides a boost to the life of the battery. iRobot points out the importance of this first charge for all versions of their products.
After the first use, the normal charging time will be about two hours. A full charge should provide around sixty minutes of cleaning time. Once your robot learns your home’s layout, sixty minutes should provide plenty of time for a good cleaning.
We don’t want to leave you with just this little bit of information. Instead, we’re going to give you a few maintenance ideas for your Roomba. We’ll also answer a few of the most frequently asked questions people have about their batteries.
Giving your Roomba an intense first charge will add to its battery life. There are a few other things you do. Try out these ideas:
Press the CLEAN button. The LED lights will indicate the charge level. Here is a guide to the meaning of the lights:
The battery is too low to allow any cleaning. Return the robot to its charging station and allow it to charge. If the battery has been depleted for a long time, the vacuum will go into a 16-hour refresh cycle.
If you notice the cleaning time of your Roomba decreasing, it may mean your vacuum needs to be reset. You may not need a new battery. There are some simple steps you can follow to reset your Roomba and get some more life from its battery.
Different Roomba models have different ways of rebooting:
For Roomba with Dock and Spot Buttons (e, 500, 600, and 800 Series)
For Roomba with the CLEAN button
As we said, this indicates the Roomba has entered its 16-hour refresh cycle. Just leave it alone and it will come back online normally when the battery is ready.
There is no magic number here. However, if you take good care of cleaning your robot, then the battery should last for a long time. Buildup of dirt, hair and debris in the wheels of the robot will stress its parts during cleaning. This could lead to more discharging than required.
You only need to replace the battery if its cleaning time has been severely reduced from normal.
Of course! Go to iRobot’s website and order a replacement. They should also have clear instructions to guide you through the process. Don’t use a cheap, fake battery. These may cause problems during charging and cleaning.
Absolutely! The battery is made to be discharged and recharged frequently. If you allow it to return to its charging station after every use, you will be extending the life of the battery. The exception to this is vacation storage. If you’re going away for more than a few days, let the Roomba charge and then store it somewhere safe.
Every day or every other day. There are two reasons for this:
How long does it take to charge a Roomba? Just two hours. Of course, there’s more to it than such a simple answer. Let us know if you have more questions or better suggestions.
