Is your Roomba’s battery not holding a charge like it used to? Don’t worry, battery issues are common with these helpful robots. This guide will walk you through troubleshooting and fixing your Roomba’s battery, so you can get back to effortlessly clean floors.
1. Clean the Charging Contacts
One of the most common reasons a Roomba won’t charge is dirty charging contacts.
How to Clean:
- Unplug the Home Base/Clean Base from the power outlet.
- Use a lightly dampened melamine foam (like a Magic Eraser) or a cloth to clean the contacts on both the Roomba and the charging base.
- The contacts should be shiny when clean. Dull or discolored contacts (green or copper) may be damaged and need replacement.
- Ensure the power cord is firmly connected to the Home Base and the wall outlet.
2. Reset the Roomba Battery
Sometimes, a simple reset can resolve charging issues. Here’s how to reset your Roomba’s battery:
- For Roomba 500 and 600 series:
- Turn on your Roomba by pressing the “Clean” button.
- Press and hold the “Spot” and “Dock” buttons (located above and below the “Clean” button) for 10 seconds.
- Release the buttons simultaneously. You should hear the typical Roomba startup sound.
- Place the Roomba on the charging base for at least 12 hours, or until the “Clean” button turns green.
- Alternative Reset Method (for various models):
- Remove the Roomba’s battery.
- Unplug the charging connector.
- Press and hold the Power button for 30 seconds.
- Reinstall the battery and connect the charger.
3. Check the Home Base/Clean Base
The problem might not be the Roomba itself, but the charging base.
- Inspect the power cord: Make sure the power cord is not damaged and is securely plugged into both the base and the wall outlet.
- Test the outlet: Try plugging the base into a different outlet to rule out an electrical issue.
- Ensure proper docking: Make sure nothing is blocking the Roomba from properly docking. The robot should make a beep sound when correctly placed on the dock.
- Replace the Base: If the light on the dock doesn’t turn on, the dock may not recognize the robot and need replacement.
4. Reinstall or Replace the Battery
Removing and reinstalling the battery can sometimes resolve the issue.
- Turn the Roomba upside down on a flat surface.
- Use a screwdriver to loosen the edge sweeping brush and any screws that retain the bottom cover.
- Remove the bottom cover.
- Unclip the battery to remove it.
- Insert the battery back in. The battery tab will secure it into place.
- Place the bottom cover back on the robot and then tighten the screws.
If the Roomba still won’t charge or has a short runtime after troubleshooting, the battery may need to be replaced. Roomba batteries typically last for 1 to 3 years with proper care.
How to Replace the Battery:
- Purchase a new, iRobot-approved Roomba battery that is compatible with your Roomba model.
- Follow the steps above to remove the old battery.
- Insert the new battery into the battery compartment, ensuring it’s properly connected.
- Reassemble the Roomba.
- Allow the Roomba to charge fully before its next cleaning cycle.
5. Battery Maintenance Tips
To extend your Roomba’s battery life:
- Use iRobot batteries: Only use iRobot-approved batteries.
- Optimal charging temperature: Charge the Roomba at room temperature, away from direct sunlight.
- Keep the Roomba clean: Regularly clean the Roomba, especially the brushes and wheels, to reduce strain on the battery.
- Fully discharge occasionally: To maintain battery capacity, occasionally run the Roomba until the battery is fully depleted, then charge it to full.
- Vacation mode: If you’re going away for an extended period, put the Roomba in “vacation mode” or remove the battery to preserve battery health.
