Roomba Error Codes. What to do when you encounter them

Roomba error codes and what to do about them.

Nobody likes it when an expensive piece of equipment fails – Especially one that has the important job of keeping your floors Roomba Error Codesclean like the Roomba. Fortunately not all error codes are a big deal, and I’ll show you what you need to know to fix them. A lot of the time you won’t have to replace any parts or put any money into your Roomba


 Common Roomba error codes

Roomba will tell you if there’s an error by sounding a two tone alert, that sounds like uh-oh. Immediately following the alert tone there will be an a series of beeps or a voice explaining the error.

Error 1 – 1 Beep

Roomba’s wheels are stuck. Check to see if there’s something caught in the wheel, move Roomba to a new location then start it. Most people find that making sure the wheels are gunk-free then picking it up, putting it back down and restarting fixes the issue.

Error 2 – 2 beeps

There’s something blocking the Roomba’s brushes. These can get dirty fast depending on how much hair you have on your carpets, especially if you have ladies in the house with longer hair. ┬áLearn how to clean the brushes here

Error 5 – 5 Beeps

Not to be confused with the common charging error 5. This means that the side wheel is stuck.

Here’s a nice video explaining how to clean this Roomba error code

Error 6 – 6 Beeps

Roomba’s cliff sensors are going haywire. Your Roomba is probably not dangling off a cliff and the sensors are just dirty. Wipe them off with a cloth.

Error 9 – 9 beeps

This means that Roomba’s bumper is dirty or compressed. Just give Roomba a good solid tap on the bumper (sides) a few times and it usually clears this error.

Error 10 – 10 Beeps

Roomba’s side wheels are dirty. Spin them briskly, tap them to loosen any dirt that’s been accumulating in them and try again. repeat this a few times and the error should clear itself up.

Error 11 – 11 beeps.

No voice message will accompany this error. This is usually a serious problem, a side wheel may be stuck (or the motor in the side wheel might be having issues). Or a bumper sensor is on the fritz. This one’s worth calling iRobot customer service over because it’s not usually an easy fix and has proven to be tough to troubleshoot.

Roomba error codes related to charging

Charging error codes are different than the standard mechanical Roomba error codes. Here’s what to do when you encounter a charging error code:

Err1 – 1 Blink

Ensure that your battery is seated properly. This means that there’s not a battery connection. Try cleaning the battery contacts with a soft cloth, and if your Roomba is old you can try bending out the contacts with a pen in order to make better contact with the battery. The contact fix process is described here

Err2 – 2 Blinks

This happens when your Roomba detects an unusual level of electric current. This usually means that Roomba is dead unfortunately, but some people have had success in replacing the power supply. If your Roomba is old and out of warranty it may be worth a shot.

Err3 – 3 Blinks

Similar to Err 2, but a new power supply, according to my research and experience will not have a chance at saving your Roomba. This one’s bad! Fix under warranty or find a good deal on a new Roomba here

Err5 – 5 Blinks

I have an entire article dedicated to this error. Probably, in my experience the most common one.

Err6 – 6 Blinks

The battery is overheated. Wait at least an hour, and try to charge Roomba in a cooler environment.

Err7 – 7 Blinks

Pretty much the same thing as 6, except that instead of the battery being overheated this one means that the battery isn’t cooling down fast enough. Again, the fix is to unplug Roomba for a while and try to charge in a cooler environment.

I hope that some explanation of these Roomba error codes has helped you a little. There’s also information on iRobot support site, if you need it. Feel free to check out some of my other articles and click the share buttons to share this on Facebook or twitter.
