Full Roomba Maintenance Guide (Dustbin, Filter, Bruses & more)

Last updated on April 11th, 2024

Roomba owners need to have thorough knowledge about the maintenance of each Roomba component. It is difficult to get all that information from a single source. We have solved that problem and created a comprehensive maintenance guide for Roombas.

Here, you will not only find the frequency in which specific components need maintenance but also detailed procedures to clean and maintain each of these components.

Roomba maintenance procedure

The following are the procedures for maintaining each of the Roomba components.


Cleaning the dustbin (Roomba maintenance)
Cleaning the dustbin

A Roomba dustbin needs more frequent cleaning. It is constantly in contact with dust, which can lead to forming a layer inside the dustbin or even a foul smell. Now, those having a self-emptying base could skip this for a bit, but you will eventually need to do it. To do it, follow the steps:

Step 1: Firstly, throw out all contents of the dustbins in your regular bin.

Step 2: Then, wash the dustbin under flowing water from the tap. You can use a mild soap.

Step 3: Make sure the filter is not installed while cleaning because it is not washable.

Step 4: Then air dry the dustbin and install it back only when it’s completely dried.


Tapping to clean the fillter

The filter is usually located on the side of the dustbin. Gently remove it and tap out the accumulated debris. Doing this is essential because if the filter gets blocked, its efficiency will decrease. It will not be able to trap allergens as effectively. The cleaning process could even show an error if the filter is blocked. Follow these steps to clean it.

Step 1: Try to clear out as much debris as possible by tapping.

Step 2: If you think there’s still something left, then use a small brush to get between the grid of the filter.

Step 3: Alternatively, if you have a handheld vacuum, you can use it to suction out all dust particles from the filter.

Main brush

When you turn your Roomba upside down, you will find a plastic frame guarding the brushes.

  • Lift the two yellow tabs on this frame to open it.
  • After opening, you will be able to take out the brushes.

The one with bristles needs more cleaning as hair gets more tangled in it. Sometimes, you might even have to cut out the hair tangled in this brush. The rubber brush could also have hair around it, but those could be removed easily. Don’t forget to remove the yellow brush caps on either side of the brush. Clean under the caps, as sometimes hair gets stuck there as well.

  • Once done cleaning, place the caps back on and insert the brushes in their position.
  • Place the protective frame back on the brushes.

Side brush

The side brush is the one located on the edge of the vacuum. It usually needs cleaning only once a week. But if you have pets, more hair could get tangled around it. So clean it twice a week to be on the safe side. If hair is tangled in the side brush, its performance is slowed down. Follow the steps given below to clean it.

Step 1: To clean the side brush, turn your Roomba upside down.

Step 2: The brush is pinned in with a screw, so get a screwdriver to unscrew it.

Step 3: Take the brush out and remove all debris that is tangled around it and its position.

Step 4: Then screw the brush back in.

Step 5: Make sure you keep the screw secure. If you lose the screw, buy it from the iRobot Store or an authorized retailer.

Charging contacts

Charging contacts are the shiny surfaces that align with the docking station. There are two contacts on the robot and two on the dock. You must clean all of them. iRobot recommends you use a dampened melamine foam to clean them. They are easily available in the market. Magic Eraser will do just fine if you can get your hands on one.

Simply wipe the contact with the foam. Make sure they are always shiny. Don’t let them catch rust, or it will highly affect the charging process.

Castor wheel

The following are the steps to clean the front caster wheel on your Roomba. It is the small wheel at the front of the vacuum’s base.

Step 1: Pull the caster wheel firmly to remove it from the robot.

Step 2: Spin it with your hand. If it doesn’t spin freely, take out the wheel from its housing and remove any dirt stuck inside the wheel cavity.

Step 3: Remove the axle completely from the wheel by pushing firmly on the axle.

Step 4: Check the axle for any debris or hair tangled around it and clear it.

Step 5: Wipe the wheel clean to ensure it’s free from any remaining dirt.

Step 6: Insert the axle back in and make sure both sides of the axle snap securely in place.

Step 7: Place the wheel back into the housing. If the wheel keeps falling out, contact iRobot Customer Care for support.

Step 8: Install the caster wheel back into your Roomba.


The sensors are the easiest to clean. Most of them you need to clean once a month. The dustbin sensors need more frequent cleaning as they come more in contact with debris.

Cliff sensors

Cliff sensors are located at the base of the vacuum. They are 4 to 6, depending on the model of your Roomba. Locate these sensors and just use a soft towel to wipe them down. Make sure dust doesn’t accumulate on them, or it could cause problems for navigation.

Full bin sensors

The full bin sensors are located inside the dustbin. There are 2 of them on either side of the bin. They get dirty very often because they constantly come in contact with dirt, dust, and debris. Use a cloth to clean these sensors. If they still have something stuck to it, use a soft brush to scrub it away.

Floor tracking sensor

The floor tracking sensor is located at the right-hand side of the base of the vacuum. It’s a small circular opening, hardly noticeable. Just swipe a cloth over the opening. Don’t insert anything in the opening, as it will damage the sensor.

Only a few select models of Roomba have a camera. This is usually a small lens on the top or front of the vacuum, depending on the model. Locate the camera on your model and clean it once every month. You can use a soft towel or a microfibre cloth to wipe the camera lens. To obtain the best results, use a screen cleaning solution.

Don’t spray the solution directly on the camera, as it can spread and seep into the vacuum. Instead, spray the cleaning solution on a microfibre cloth and then use that cloth to wipe the lens.

Main body

The main body of the Roomba collects dust and fingerprints quite easily. The shiny surfaces on a few models look particularly dirty if you let them be. We recommend getting a good microfiber cloth to wipe the surface of the Roomba. Don’t put too much pressure; just do a quick wipe. Do this after every cleaning cycle, if possible. This will prevent dust and fingerprints from accumulating on the Roomba’s body.


These maintenance techniques will help keep your vacuum in the best shape. Doing timely maintenance has often led to Roombas having a long life. Without timely cleaning and replacement of parts, Roombas wear out fast and give a diminished performance. If your Roomba is not performing as well as it used to, it’s time to give it a thorough maintenance check.

Happy Cleaning!
