How to Clean bin sensors on a Roomba? (10 Easy Steps)

Last updated on January 9th, 2024

Bin sensors are responsible for alerting you when your Roomba’s dustbin is full. They sense when the dustbin reaches its capacity and turn on the indicator light on the robot. Wi-Fi-enabled vacuums also send a notification on the iRobot Home app when the bin is in full.

All of this is possible because of the bin sensors. It’s vital that you clean bin sensors on a Roomba and keep them free of debris so they don’t give any errors.

Cleaning Roomba bin sensors

To clean bin sensors on a Roomba, use a microfibre cloth to wipe them clean. If there’s still debris on them, use a small soft brush to agitate and remove it. Don’t forget to disinfect the inner bin sensors from time to time because they constantly come in contact with debris. Use an alcohol-based cleaning solution for this purpose.

You should start off by locating all the bin sensors. There are a total of 6 of them. Let’s see where to find them.

Locating the bin sensors

The 6 bin sensors of a Roomba are located in three different locations around the dustbin. They are:

  1. On the robot where the dustbin is placed
  2. On the outside of the dustbin (outer sensor ports)
  3. On the inside of the dustbin (inner sensor ports)

All these sensors need to be cleaned from time to time. Otherwise, they will show an error. Error 36 indicates that the full bin sensor is not cleared when the debris is emptied. If you see an Error Code 36 on your vacuum, know that you need to clean the full bin sensors.

Cleaning the sensors requires some tools.

Tools required

Gather all these items before you take out your dustbin and set them in an accessible location. So once you empty the bin, you can clean bin sensors on a Roomba right away. For this, you will need the following:

  • A microfibre cloth
  • A soft brush
  • Q-Tips
  • Cleaning solution

These items are usually available in most households. If not, they are easily available online at very cheap prices. We recommend buying these items as they are common for cleaning several parts of a Roomba. Once all is set, you can get to cleaning. But don’t forget to take the necessary precautions before, after, and while cleaning the bin sensors.

Take these precautions

Taking all the measures below will ensure that your bin sensors remain in tip-top condition.

  • Don’t use water directly on the sensors.
  • Don’t let the sensors rust.
  • Don’t cover the sensors with anything.
  • Don’t scratch the sensors.

While keeping all these things in mind, start cleaning the bin sensors on your Roomba.

Cleaning procedure

You can follow the below procedure to clean bin sensors on a Roomba.

Step 1: Start by taking out the bin from your Roomba.

Step 2: Empty the contents of the bin and clean it with a soft towel.

Step 3: Before you empty the bin, place the Roomba upside down on a soft towel.

Step 4: Now, locate all 6 bin sensors on the Roomba.

Step 5: Start cleaning them one by one.

Step 6: Take a microfibre cloth and swipe it around each sensor to rid it of any debris.

Step 7: If there’s something stuck to the sensors, use a soft brush to remove it.

Step 8: For hard-to-reach areas, use Q-Tips to clean the sensors.

Step 9: Use an alcohol-based cleaning solution to wipe the sensors later so that they get disinfected.

Step 10: Ensure all the sensors and the dustbin are completely dry before you insert it back into the vacuum.

There you go! That’s all you need to do to clean the bin sensors on your Roomba.

Final Thoughts

Cleaning bin sensors is an essential part of Roomba maintenance. Unclean bin sensors give errors like showing the dustbin is full even if it isn’t. That’s why it is important you clean them at least once a week. The process is simple, but it needs to be done thoroughly to maintain their health. If a problem persists with the bin sensors, try to reset your Roomba.
