Roomba Charging errors:

There are some common charging issues your Roomba faces that you can fix in no time.

Charging Error 1

This is more like a mistake than an error. This happens when you forget to connect the battery after assembly or don’t connect the battery properly. So the Roomba warns you of the unavailability of the battery with a single beep.

Just check the battery and connect them properly.

Charging Error 2

Your Roomba will warn you about this type of error with two beeps. This mainly occurs when the battery is overheated because of the extra current above the recommended ratting or the batteries are fake.

In this case. Just unplug the robot and let it sit for at least 3-4 hours. Then you need to check the batteries if they are original. This case is common in the Roomba series 500 and the later models.

Charging Error 3

This kind of error will warn you with 3 beeps at once. All you need to do is reset the robot and recharge it (Help the Roomba to get back to its charger).

Charging Error 5

This happens when you first buy the Roomba. There is a yellow stripe that breaks the circuit and cuts the power system.

You need to reboot the Roomba to solve this problem.

Charging Error 6

In this case, you will find that you’re your battery is not charging anymore. This happens when your batteries overheat to the max point that it stops charging.

You need to unplug the Roomba and let it be until it cools down. After that put it in the plug again and recharge. If you find the Roomba is charging properly, then you are good to go. But if the Roomba is still not charging then you need to replace the battery.

Charging Error 7

If you find the continuous occurrence of error 6 mentioned before then it is time you think about replacing your batteries as early as possible. This error is considered an error 7.

These were all the common charging issues you will find in your Roomba.

Roomba vacuum operational errors

Operational errors are mostly simple bugs that you can fix in no time with just some simple tips. This error will alert you with a different number of beeps. You have to recognize the problem of counting the beeps.

Beeps 1 time or Error 1

If you hear a single beep then your Roomba may have stuck at any place or a side wheel is hanging.

In this case, move your Roomba and press the ‘CLEAN’ button to start. Now you have to check the side wheels of your Roomba. Look for any obstacle in the wheel such as stuck hair or so. You can do this by pushing the wheels back and forth to make sure the wheels are clean. Check each wheel separately to find the equal resistant level on each one of them.  And then check the wheel assembly with a vacuum to complete the final check.

Beeps 2 times or Error 2

These 2 beep indicates that the brushes have accumulated so much dirt that they can’t turn anymore.

For this first, you need to open the brush case and check the bearings. Make sure there isn’t any dirt stuck on the brush blocking the turning by giving them a wash. Also, wash the gears and the bearings, and the cases. Replace the brushes if needed. After all the cleaning, assemble the brushes, gears, and bearings properly.

Beeps 5 times or Error 5

This one is related to the side wheels. Your Roomba will alarm you with 5 beeps if there is an obstacle in the side wheels that will prevent the wheels from functioning properly. Check for any stuck hair or dirt on the side wheels and remove them. For this just flip the robot and push the wheels to see any obstacle. When you get rid of the obstacle check for the same level of resistance on both wheels. And finally, clean the wheels with a vacuum.

Beeps 6 times or Error 6

This type of 6 beeps will warn you about your cliff sensors. Either the cliff sensors have accumulated dirt or are stuck over a cliff.

To fix it wipe the sensors with a clean dry cloth or blow compressed air to properly clean the sensors.

Beeps 7 times or Error 7

This one is also related to the side wheels as error 5. This means anyone or both the side wheels are stuck. These obstacles will prevent the wheel from turning any further.

To fix it, check for any stuck hair or dirt on the side wheels and remove them. For this just flip the robot and push the wheels to see any obstacle. When you get rid of the obstacle, check for the same level of resistance on both wheels. And finally, clean the wheels with a vacuum.

Beeps 8 times or Error 8

This will indicate that the Roomba is stalled in one place because the caster at the front is stuck or the whole vacuum is stuck.

To get rid of it just clean the front caster and you are good to go. But after cleaning if the caster is still stuck then it is time for you to change the caster of your Roomba.

Beeps 9 times or Error 9

In this case, you need to concentrate on the area between the frame and bumper with the whole body. This alarms you that there is dirt in the sensors. So you need to clean the sensors along with the whole Roomba. This way your Roomba will work just as new. Just check the bumper in the case by pushing it back and forth to make sure it is clean.

Beeps 10 times or Error 10

This has a unique meaning to these 10 beeps. This means your Roomba hasn’t identified anything as an obstacle yet. But it also indicates that the side wheels are stalled due to some obstacles. You need to check the side wheels as mentioned before for any dirt accumulation. And check the resistance on each wheel. Finally, clean the wheel with a vacuum.

Beeps 11 times or Error 11

This is similar to error 10. This indicates that the Roomba hasn’t found any obstacle yet. This is likely to happen in a larger room with less furniture.

Try using a hand vacuum for this type of room.

Beeps 12 times or Error 12

This is similar to the cliff sensor error mentioned before. When the cliff sensor is dirty and can’t do the job properly, the Roomba will beep 12 times to let you know this.

Wipe the cliff sensors to get rid of this problem. But if this error continues, try to get the sensor replaced as soon as possible.

Some Roomba error message charts you may check.

Hope it will help you,


Final Words

Roomba is one of the most convenient ways of cleaning the house with less effort. But like all other electrical devices, this will also need some regular maintenance. Check for the side wheels, bumper, gears, bearing, sensors, and brushes on a regular basis. This will keep away your Roomba from any trouble.

Even if you’re Roomba shows any sign of the errors mentioned above, don’t panic and just follow the Roomba vacuum troubleshooting guide. This way you will be able to solve the problem by yourself at home in no time.

    • Hey Jerry, this means the virtual walls are in odd places; where they shouldn’t be. Your roomba robot is experiencing problems configuring where to go and where not to go. Maybe they are facing each other. Can you send me an overview of the placement of the barricades?

  1. Roomba e6 moves around in circle, makes normal noice, brush does not move, roomba stops with green battery light on, and red error code light on and blinking. I have taken battery out twice, and rebooted several times. Please help.

    • My room a 980 battery went out and I purchased a higher capacity battery installed it and upon placing it on the charger I receive error code 3. Do you know what could be the problem?

    • Maybe the problem is external, there are debris stuck in one wheel and making it move in irregular angle. Clean the debris and it will be fixed.

  2. Roomba 650 works. So I know the battery is in correctly. But I get the “Charging Error 1” when I attempt to charge in docking station. I have cleaned all the metal charging “terminals” and still get the error. Any other thoughts or suggestions?


  3. Hi, could you help me with an error one message on my Roomba 500?
    I’ve recently replaced the battery, I noticed that the new battery is 4500mAh but the old one was 2500mAh.
    The only way I’ve been able to charge the battery is to lay the unit on its back and remove the undertray and plug the power able directly into the Roomba.
    If the unit returns to the dock it reports an error. If I plug the power cable directly into the unit, it reports an error.
    The battery looks identical apart from the earlier mentioned difference.
    I’ve tried holing down the spot & dock buttons to reset but nothing seems to happen.


  4. My s9 says error 31. From my research, it looks like it’s the kiss of death. It worked for the first 3 weeks, but now is throwing this code. I’ve done everything you’re supposed to do, and the problem persists. I bought it from a reputable dealer on eBay, new. However, eBay isn’t an authorized roomba dealer, so iRobot won’t exchange it. I’m just trying to figure out if there’s anything I can do so I didn’t waste $1,000! Any help would be greatly appreciated!

    • You might be well acknowledged of the fact but telling anyway, it means internal communication error. Perform a reset and see if that helps.

      And hey, you are the reason I always suggest buying from an authorised store.

  5. Hi,

    I have an old 500 series Roomba that sat neglected for years. I thought it had died. I did some reading and realized it needed a battery replacement, so ordered one (Ni-Mh) from Amazon, cleaned the machine, replaced parts and battery and, as it says the battery needs to be fully charged before first use, put it on the charger. I got error message 1. I checked the placement of the battery and repeated the process — twice. Got the same error message. I did a reset, holding the power button down for a few seconds, unplugged it and turned it on. It was fully charged and ran for about 45 minutes. Then I got the “charge Roomba” message, put it on the charger and got, once again, error message 1.
    Please explain, if you can. Thanks. At this point the button is flashing red, so I don’t know if it is charging or not.

    • Seems like the battery is okay since it already gave a backup of 45 minutes. Did you do what you did in the first place, the whole procedure again but nothing happened? let me know

  6. Thank you George for publishing this info. It helped me solving my Roomba 960 sensors’ error. I was going to go through the return process, but I wanted to make sure I wasn’t overlooking any instruction when I found your site. Thanks to the clear instruction (which I couldn’t find in my manual!) about how to clean thoroughly the vacuum cleaner, I was able to solve the problem and now my Roomba is perfect!

    Thank you again

  7. Hi! My roomba 650 has error 6. Bit there is nothing wrong with it. We have Remove and clean both large wheels and small wheel. Removed bumper and cleaned. Cleaned the brushes. EVERYTHING. Removed battery and put back in. And factory reset it .. but the error continues. please help!!

  8. Had an old roomba 550 in storage. Ordered an off brand replacement battery to get it working again. Old battery and new battery give charging error 7 from dock and direct plugged.It acts like it’s charging on all chargers all different ways but then about 4 hours into it it throws the error code. I’m pretty confident it’s not the charger. Roomba worked fine with the new battery 1st run. Tried to charge in several rooms so it’s not an outlet or climate issue.

    • Maybe the old battery is drained out of juice and the new one is occuring problem for being unauthentic. We recommend using an authentic battery from Roomba.

  9. I have a Roomba 560 that I recently resurrected from storage. It was working great for a few weeks but now when I go to start it, it will begin to run for about 5-10 seconds then stop and do the “Uh-oh” tone as it blinks red I think 7 times (could be 6). There is no other audio indicator other than the “Uh-oh”. I’ve cleaned all sensors, wheels, brushes and berrings thoroughly. No change. Please help!

  10. What do I do now? My error 7 is telling me i have bought a counterfeit replacement battery. Its always blinking red now. I did a hard reset a couple weeks ago, but this problem returned. It still operated after the reset. Do i just need to keep doing hard reset?
    Do i need to worry about counterfeit battery?

    • The issue is complex here, so we recommend you take the device to authentic customer service and ask for expert help. If you are having a warranty then utilize that.

  11. My roomba i3 keeps stopping and saying Error 30 even after we’ve cleaned out the bin and changed filters multiple times. What do I do now?

    • Though the vacuum is experiencing insufficient airflow, cleaning the bin would have solved it. If didn’t we would recommend to run a factory reset.

  12. Hi, I set my Roomba i7 to clean, it will go forward a short distance, stop and go backwards quickly then stop. A message did say check the wheel.The clean light comes on red, I did clean the wheels and brushes.

    • After cleaning the brushes and wheels if it keeps showing the same message, go for a quick reset. Hope it will solve the issue.

    • Your Roomba i3 is stuck in the infrared (IR) beam of a Virtual Wall® or Home Base®, you should take it to a new location manually.

    • Though it is not a charted issue by the provider, you can check whether the side wheels are stuck or not. Clearing the wheels may solve your issue.
