Clean charging contact points

Roomba not charging? The first thing you should do is clean the charging contacts. Over time, these contact points can become dirty or corroded, preventing the Roomba from charging correctly. To clean the contact points, simply use a cotton swab or Q-tip dipped in rubbing alcohol. Next, gently rub the charging contacts until they are clean.

How to Clean the Charging Contacts

Clean the Charging Station

In addition to cleaning the charging contact points, you should also clean the charging station. The docking station can become dusty or blocked, preventing the Roomba from properly charging since it does not have a sufficient power supply. To clean the docking station, use rubbing alcohol and a soft cloth to wipe it down.

Clean the caster wheel

If your Roomba is not charging, the caster wheel may be to blame. The caster wheel is located at the front of the Roomba and helps it move around. Unfortunately, over time, this wheel can become dirty or clogged.

The contact points of the Roomba won’t reach the contact points of the Home Base if the caster wheel has been pushed up. As a result, the device will not be able to charge itself. To resolve this, remove any debris obstructing the caster wheel.

Check if the Battery is Placed Properly

It’s possible that your Roomba won’t charge because its battery is not placed correctly in the battery compartment. If the battery is inserted incorrectly, it will not connect well with the charging contact points. As a result, the Roomba will not charge. To fix this, simply remove the battery and reinsert it.

Reset the Roomba

If your Roomba isn’t charging, it may be due to software bugs. A soft reset can clear these glitches and let your Roomba work like new again. To reset your Roomba, press and hold the clean button on your device until you hear a beep. Then, plug your Roomba back in, and it should display a charging indication.

700 and 800-series have a dedicated reset button. In that case, you can simply hold down that button to reset the device.

Try another Power Outlet

If your Roomba is still not charging, try plugging it into a different power outlet. It’s possible that the outlet you’re using is not working correctly. To test this, plug something else into the outlet to see if it powers on. If it does, then the outlet is probably not the problem.

Factory Reset the Roomba

You can try a factory reset if a soft reset doesn’t work. This action will restore your Roomba to its default settings. However, a factory reset will erase any customized settings or routines stored on the Roomba, so ensure that you back up your data first. 

The easiest way to do this is to use iRobot HOME App. A factory reset will remove the robot from your iRobot HOME App and disassociate any saved data from the iRobot cloud. To do this, open the iRobot HOME App and ensure your mobile device is connected to the same Wi-Fi network as your Roomba. Then, press Settings and select Remove/Factory Reset (robot name).

Replace the Battery

If none of the above steps work, it’s possible that your Roomba’s battery is damaged and needs to be replaced. You can buy a replacement battery from iRobot or a third-party retailer.

Once you have a new battery, simply remove the old one and insert the new one in its place. Don’t forget to remove the battery pull tab. Make sure that the battery is inserted in the proper direction.

How to maximize your Roomba battery life?
