How to clean the side brush on a Roomba

The side brush is on all Roombas and helps sweep dirt, dust, and hair into the vacuum's suction. However, that same dirt and dust may stop it from being trapped under the unit. Side brushes also can get old and go wrong, so we'll discuss what to do in each situation. Grab your Roomba, and let's dive into it.

Step 1: Clean dirt from the brush.

The first and most common action that you'll have to do is clean the dirt from the brush. Next, you'll have to remove the brush using the screws underneath it. Then, remove all the dirt in and around the side brush.

Step 2: Clean dirt from the gearbox and motor compartment.

Unscrew the back part of the Roomba and unscrew the side brush along with all visible screws. From there, you will clean out all the dirt and dust you see.

Step 3: Lubricate the brush.

While you have access to all components, take this time to lubricate the side brush module with oil. When the brush gets old, it can stick more and more due to rusting. Once you're finished, reassemble your Roomba.

Step 4: Replace the brush.

After cleaning and lubricating, if your brush still isn't spinning you'll need to replace it. For most Roomba models, iHome either includes an extra replacement brush, or you can order one from the company.

However, it's possible for the wear and tear to be too much or the brush to be physically damaged, which is another reason why you'd replace it.

Step 5: Replace the Roomba.

If the brush still doesn't work after replacing it, there are a couple of things that could be wrong, including an issue with the robot vac's motherboard or battery. Though these things likely affect your entire Roomba, you should look into either having iHome replace it or buying another one.

Even if you need to replace parts, it's much more affordable than buying another Roomba.

The Saros Z70 is the most exciting robot vacuum I’ve ever seen

Out of all the robot vacuum brands available in 2025, Roborock is probably my favorite. The company has been churning out premium, reliable, and powerful robots for years, with their releases consistently landing on our best robot vacuum and mop roundup. CES 2025 was filled with intriguing smart home reveals, but the Roborock Saros Z70 is by far the coolest upcoming device. Designed with a robotic arm that can pick up small obstacles that get in its way, it’s the most innovative robot vacuum I’ve ever seen -- and I’ve never been more excited to see how it shakes up the industry.

Robot vacuums are intended to be autonomous assistants that roam our homes and keep floors clean with little manual intervention. But far too often, this isn’t the case. Whether it be poor sensors that cause the robot to get stuck, suction power that’s inadequate to pick up troublesome debris, or poor obstacle navigation that causes it to get tangled in your phone’s charging cable, some robots simply aren’t as hands-free as expected.

Ecovacs shows off powerful Deebot X8 Pro Omni robot vacuum at CES 2025

Ecovacs came out swinging at CES 2025, revealing a slew of smart home products running the gamut from robot vacuums and lawnmowers to bizarre window-cleaning robots. The star, however, was the Deebot X8 Pro Omni -- a powerful robot vacuum that makes big changes to its mopping abilities thanks to a new collaboration with Tineco.

Though it didn’t pick up a robotic arm like the Roborock Saros Z70, the Deebot X8 Pro Omni did learn some cool new mopping techniques. There are two big upgrades here, the first being additional pressure while mopping. The X8 Pro Omni can create up to 4,000Pa pressure and spin at up to 200 rpm, which should result in better cleaning than anything else we’ve seen from Ecovacs so far. The other upgrade is a self-washing mop, which continually cleans itself while mopping your floors, ensuring every mess is tackled by a clean mop.

Narwal debuts innovative robot vacuum with new mop-cleaning functionality at CES 2025
Narwal Flow

Narwal is responsible for some of our favorite robot vacuums, including the premium Narwal Freo Z Ultra, which features a modern aesthetic and ultra-quiet operation. The company’s track record of innovation continued at CES 2025 with the reveal of the Narwal Flow -- an upcoming robot vacuum built with a powerful new mopping system.

The Narwal Flow employs a new type of mopping system (dubbed the FlowWash Mopping System) that actively cleans its rolling mopping plate as it's cleaning your floors. This ensures you won’t be tracking dirty mops across the ground and should result in a better overall cleaning experience. The robot is equipped with both a clean and dirty water tank, allowing it to extract dirty water from the mop while simultaneously rewetting it. This allows the mop to remain in excellent condition without needing to head back to the docking station for self-cleaning.
