If you’re using a Roomba, there’s a good chance you may have come across the Error 6 that Roomba threw when it became stuck over a cliff or when its cliff sensors were dirty.
Like other Roomba errors, it seems as if this error message would be straightforward; there are multiple ways to fix this error, so you’ll want to take some time to read through this article before proceeding with any fixes of your own!
Why does Roomba Error 6 occur?
Sometimes an error code is just a code, and there isn’t anything wrong with your robot vacuum. But sometimes, this can be frustrating, mainly when it occurs before you’ve even had a chance to use your device for its intended purpose. So, what causes Roomba Error 6?
According to iRobot, there are a couple of reasons why you might see error code 6 on your robot. They might be,
- The cliff sensors of your Roomba may be dirty or damaged.
- Roomba is stuck on the edge of a cliff or a dark surface.
I will discuss those issues and offer some troubleshooting tips to help you fix the problem.
How to fix Roomba Error 6 issue?
In short: To troubleshoot error 6 in the Roomba vacuum, check whether the cliff sensors are dirty or damaged. The cliff sensors are located on the underside of the Roomba, and they’re used to detect drop-offs (like stairs). If the sensors are dirty, clean them with a soft cloth. But if cleaning the sensor doesn’t work, you may need to replace them.
Well, this was the most useful and practical solution, and I will explain this process in detail below. But before that, look at the below table for a better understanding…

Genuine cliff sensor for Roomba
As you know, the main culprit for Error 6 is a dirty or broken cliff sensor. So if after cleaning the sensor doesn’t fix the issue, you must replace the cliff sensor.
Step 1: Clean the cliff sensors
The first and most effective way to fix the error 6 issue in a Roomba is to check and clean the cliff sensor. There are almost three cliff sensors in a Roomba.
If one is dirty, your Roomba will stop working and show you an error telling you that you need to clean the sensor. So, to clean your Roomba’s cliff sensor, follow these steps:
☞ Gather cleaning aid
Before you start, you need the following things,
- An old bath towel.
- Some paper towels.
- Cotton Swabs.
- A window cleaner bottle or water.
☞ Locate the cliff sensor and clean it
Turn your Roomba off and set it upside down on a towel in front of you to find the cliff sensors. Then use a can of compressed air to blow away any dirt or debris to clean the cliff sensors.
You can also use a cotton swab dampened with rubbing alcohol or a paper towel moistened with window cleaner or clean water. Be sure to clean all three sensors (left, center, and right).
If your Roomba is still throwing an Error 6 message, you may need to replace the sensors. You can purchase replacement cliff sensors from iRobot’s website or a third-party retailer. But before that, read the further solutions listed below.
Step 2: Check for anything stuck on the brush
Another potential cause of Roomba error code 6 is that something is stuck on the brush. Ensure the brush is clear of any hair or debris to check for this.
If it looks clear, try running the brush manually to see if it’s stuck. If the meeting doesn’t spin, you may need to replace it. But if it looks good, move on to the next step.
Step 3: Try to clean the entire Roomba
If cleaning the cliff sensor and checking the brush doesn’t fix the problem, you may want to try cleaning the whole Roomba, including the side brush, wheel, battery contacts, and other parts.
Cleaning the battery contacts and other parts not only fix the error code but also charging issues too. If you are using the Roomba i7, here is a particular guideline to clean the Roomba i7 properly.
To clean your Roomba, start by removing the dustbin and emptying it into the garbage. Next, use a dry cloth to wipe the device, especially the brushes. If the brushes are filthy, you can remove them and clean them with soap and water.
Once you’ve cleaned the Roomba itself, it’s time to clean the charging base. Start by unplugging the base, then wipe it down with a dry cloth. If the contacts are dirty, use a cotton swab dipped in rubbing alcohol to clean them. Once everything is clean, plug the base back in, and you’re good to go!
Step 4: Try updating the Software
Although it seems hilarious, it can sometimes happen due to outdated Software. Keeping your Roomba up-to-date with the latest firmware can help it run its best. Newer firmware versions include bug fixes and performance improvements.
So it’s always a good idea to keep your Roomba’s firmware up-to-date. To check for any available software updates for your Roomba, follow the below steps:
- First, open the iRobot Home app.
- Then select More > Settings > About (robot name).
- If there is an update available, you will see it here.
Remember, your Roomba will automatically update its Software when connected to a Wi-Fi network or the internet. But it will only update its Software when it is not cleaned and is on the Home Base.
How to prevent this type of error?
You can do a few things to prevent getting this kind of error in the future.
☞ Always ensure that your Roomba is on a level surface. If it’s not, the sensors will get confused and cause the Roomba to think it’s stuck.
☞ Try to keep the area around your Roomba clear of obstacles. If there are too many things around, the Roomba may think it’s stuck and give you the error message.
☞ Regularly Clean off any dirt or debris in front of the bumper, and don’t forget to check the wheels.
The most common reasons for a Roomba misbehaving are a lack of proper maintenance and damaged parts, such as roller sensors or other parts.
Q. Will a factory reset help to fix it?
I don’t know! When I faced this problem, I cleaned the sensors using a soft cloth, and it worked. But if none of the above troubleshooting steps fix your situation, you can try a reset before replacing the sensor. But be sure to back up your setting if needed!
Q. Nothing worked! What should I do?
In this case, there is nothing left for you to do. It is best if you hand it over to a qualified repairer. But if your vacuum is under warranty, contact Irobot customer care.
