How to Clean Eufy Roller Brush

Keeping your Eufy vacuum’s roller brush clean is essential for maintaining suction power and extending its lifespan. This guide walks you through the complete process—from removing tangled hair to reassembling the brush—so your Eufy runs like new every time.

Key Takeaways

• Regular cleaning prevents clogs: Hair, dust, and debris build up quickly on the roller brush, reducing efficiency and potentially damaging the motor.
• Use the right tools: A cleaning comb, scissors, and a microfiber cloth make the job faster and safer than using your hands or sharp objects.
• Disassemble carefully: Follow your model’s specific instructions to avoid breaking clips or misaligning parts during removal.
• Clean both sides of the brush: Don’t forget the end caps and bearings—they collect hidden grime that affects rotation.
• Let everything dry completely: Reinstalling a damp brush can cause mold or electrical issues in motorized models.
• Schedule monthly maintenance: Even light users should clean the roller brush at least once a month for peak performance.
• Replace when worn: If bristles are frayed or the brush doesn’t spin smoothly after cleaning, it’s time for a replacement.

Why Cleaning Your Eufy Roller Brush Matters

If you’ve ever noticed your Eufy vacuum losing suction, making strange noises, or leaving behind dirt it should have picked up, the culprit might be a dirty roller brush. The roller brush—also called the brush roll or beater bar—is the spinning cylinder at the base of your vacuum that agitates carpet fibers to loosen embedded dirt and debris. Over time, hair, string, pet fur, dust, and even small bits of fabric wrap around it, creating a tangled mess that slows rotation, reduces cleaning power, and can overwork the motor.

Ignoring this buildup doesn’t just mean less effective cleaning—it can lead to costly repairs or premature replacement of your vacuum. In worst-case scenarios, excessive friction from a clogged brush can cause the motor to overheat or burn out. That’s why regular maintenance isn’t optional; it’s essential.

The good news? Cleaning your Eufy roller brush is surprisingly simple, takes less than 15 minutes, and requires only basic household tools. Whether you own a Eufy RoboVac, RoboVac G30, RoboVac L35 Hybrid, or another model, this guide will walk you through the entire process with clear, easy-to-follow steps.

By the end of this guide, you’ll know exactly how to remove, clean, inspect, and reinstall your roller brush—plus how often to do it and what to watch out for. Let’s get started!

What You’ll Need Before You Begin

Before diving into the cleaning process, gather these supplies to make the job quick and safe:

• Eufy cleaning comb (included with most models): This specialized tool has serrated edges designed to slice through hair wrapped around the brush.
• Scissors or utility knife: For cutting stubborn threads or thick tangles the comb can’t handle.
• Microfiber cloth: Ideal for wiping down the brush housing and removing dust.
• Small brush (like an old toothbrush): Great for scrubbing end caps and hard-to-reach crevices.
• Compressed air (optional): Helps blow out dust from the brush bearings or housing.
• Flathead screwdriver (if needed): Some Eufy models require gentle prying to release the brush cover.

Avoid using water unless absolutely necessary—most Eufy roller brushes are not waterproof. If you must rinse (e.g., for ground-in mud), use minimal water and ensure everything is fully dry before reassembly.

Step 1: Power Off and Prepare Your Workspace

Safety first! Always turn off your Eufy vacuum and unplug it if it’s a corded model. For robot vacuums like the RoboVac series, simply power down the unit using the button on top or via the app.

Next, find a clean, well-lit workspace—a table or countertop works best. Lay down a towel or sheet to catch loose hair and debris. This not only keeps your surface clean but also prevents small parts from rolling away.

Flip your vacuum upside down so the brush roll is facing up. You should now see the brush cover—a plastic panel that runs along the bottom of the vacuum head. On most Eufy models, this cover is held in place by clips or a simple latch, not screws.

Step 2: Remove the Brush Cover

For Models with Clip-On Covers (e.g., RoboVac 11S, G10, G30)

Gently press the release tabs on either end of the brush cover. These are usually located near the wheels. Once released, the cover should pop off easily. If it feels stuck, wiggle it slightly—but never force it, as the plastic clips can break.

For Models with Screw-On Covers (e.g., Some RoboVac L-Series)

Use a Phillips-head screwdriver to remove the two screws securing the brush cover. Keep the screws in a small bowl or magnetic tray so you don’t lose them.

For Hybrid or Wet/Dry Models (e.g., RoboVac L35 Hybrid)

These may have a slightly different mechanism. Check your user manual, but typically, there’s a lever or push-button near the brush assembly. Press it and slide the cover outward.

Once the cover is off, set it aside carefully. You’ll now have full access to the roller brush.

Step 3: Remove the Roller Brush

The roller brush sits in a channel and is held in place by end caps or brackets on both sides. Here’s how to remove it safely:

Locate the End Caps

Look for plastic or rubber caps on the left and right ends of the brush. One side usually has a spring-loaded mechanism or a removable bracket.

Release the Brush

On most Eufy vacuums, you’ll need to lift one end of the brush while gently pulling it out of its socket. Start with the side that has the least resistance—often the right side. Use your fingers or a flathead screwdriver to carefully pry the end cap outward if needed.

Once one end is free, slide the entire brush out horizontally. Be mindful of any wires or sensors connected to the brush (rare, but present on some smart models). If you see wires, disconnect them gently before fully removing the brush.

Place the removed brush on your towel. It’s likely covered in a thick layer of hair, dust, and debris—don’t be alarmed! This is completely normal.

Step 4: Clean the Roller Brush Thoroughly

Now comes the main event: getting that brush spotless.

Use the Eufy Cleaning Comb

Take the included cleaning comb—it looks like a small rake with sharp teeth. Run it along the length of the brush, working from one end to the other. The serrated edge will slice through wrapped hair and pull it away from the bristles. Repeat this several times, rotating the brush as you go.

Pro tip: Hold the brush over your trash can or towel while combing to catch falling debris.

Cut Away Stubborn Tangles

If you encounter thick knots of hair or string that the comb can’t handle, use scissors to carefully cut them. Slide the scissors between the brush core and the tangle, then snip horizontally. Never pull forcefully—this can damage the bristles or the brush core.

For pet owners: Pet hair is especially clingy. Consider using a rubber glove or a silicone brush to help loosen embedded fur after cutting the bulk away.

Clean the End Caps and Bearings

Don’t forget the end caps! Remove them from the brush and wipe them with a damp microfiber cloth. Use an old toothbrush to scrub any grime stuck in the bearing housing. If there’s grease or oil buildup (common in older models), a drop of mild dish soap on the cloth can help—but rinse sparingly and dry immediately.

Wipe Down the Brush Core

Use a dry microfiber cloth to wipe the central spindle of the brush. This area often collects dust and lint that can interfere with smooth rotation.

Optional: Rinse (Only If Necessary)

If your brush is caked with mud, dried food, or other wet debris, you may need to rinse it. Hold it under lukewarm running water for a few seconds, then shake off excess water. Do not submerge the entire brush, and never use hot water—it can warp plastic components.

After rinsing, pat dry with a towel and let it air-dry completely for at least 4–6 hours (preferably overnight) before reassembly. Moisture left inside can cause rust or mold.

Step 5: Clean the Brush Housing and Vacuum Interior

While the brush is out, take the opportunity to clean the area where it sits.

Use your microfiber cloth to wipe down the brush chamber, removing dust, hair, and debris. An old toothbrush works well for corners and crevices. If there’s stubborn gunk, lightly dampen the cloth—but avoid excess moisture near electrical components.

For robot vacuums, check the side brushes and sensors too. Wipe them clean with a dry cloth to ensure optimal navigation and suction.

If you have compressed air, give the brush housing a quick blast to dislodge any hidden particles.

Step 6: Inspect the Brush for Wear and Damage

Before putting everything back together, inspect your roller brush closely:

• Check the bristles: Are they frayed, bent, or missing? Worn bristles won’t agitate carpets effectively.
• Spin the brush manually: Does it rotate smoothly? If it wobbles or feels gritty, the bearings may be damaged.
• Look for cracks or splits: Especially along the core or end caps. Cracks can worsen over time and cause imbalance.
• Test flexibility: Gently press the bristles—they should spring back. If they stay flattened, they’ve lost their effectiveness.

If you notice significant wear, it’s time to replace the brush. Eufy sells official replacement roller brushes compatible with most models. Using a worn brush reduces cleaning performance and can strain your vacuum’s motor.

Step 7: Reinstall the Roller Brush

Once everything is clean and dry, it’s time to put your vacuum back together.

Reinsert the Brush

Slide one end of the brush into its socket, then gently press the other end into place. You should hear a soft click when it’s seated properly. Make sure the brush spins freely by giving it a manual turn.

Reattach the End Caps

If you removed end caps, snap them back into position. Ensure they’re secure—loose caps can cause noise or vibration during operation.

Replace the Brush Cover

Align the cover with the vacuum base and press it down until all clips snap into place. For screw-on models, reinsert and tighten the screws—don’t overtighten, as this can crack the plastic.

Double-Check Connections

If your model has wired sensors, reconnect them now. Refer to your manual if you’re unsure which wire goes where.

Step 8: Test Your Vacuum

Turn your Eufy vacuum back on and run it on a small patch of carpet or hard floor. Listen for unusual noises—grinding, squeaking, or excessive vibration could indicate improper installation.

Check that the roller brush spins freely and that suction feels strong. If everything sounds and feels normal, you’re good to go!

How Often Should You Clean the Eufy Roller Brush?

The frequency depends on your usage:

• Light use (1–2 times per week): Clean every 4–6 weeks.
• Moderate use (3–5 times per week): Clean every 2–3 weeks.
• Heavy use (daily) or pet owners: Clean weekly.

Signs it’s time to clean include reduced suction, visible hair wrapping, loud noises, or the brush not spinning. Don’t wait for performance to drop—preventive cleaning saves time and extends your vacuum’s life.

Troubleshooting Common Issues

Brush Won’t Spin After Reassembly

Double-check that the brush is fully seated in its sockets and that the end caps are secure. Also, ensure no debris is blocking the brush chamber. If the problem persists, the drive belt (on corded models) may be loose or broken.

Vacuum Makes a Grinding Noise

This usually means something is stuck in the brush or housing. Turn off the vacuum, remove the brush, and inspect for hidden objects like coins, paper clips, or large debris.

Brush Still Looks Dirty After Cleaning

Some discoloration is normal, but if bristles are blackened or smell burnt, the motor may have overheated. Stop using the vacuum and contact Eufy support.

Replacement Brush Doesn’t Fit

Ensure you’ve purchased the correct model-specific brush. Eufy brushes vary slightly between RoboVac series. Check the part number in your manual or on Eufy’s website.

Pro Tips for Long-Term Maintenance

• Keep pets’ nails trimmed: Long nails can scratch the brush and create more tangles.
• Vacuum in straight lines: Zigzagging increases the chance of picking up strings or cords that wrap around the brush.
• Store your vacuum properly: Keep it upright in a dry place to prevent moisture buildup.
• Use the cleaning comb after every few uses: Quick combing prevents major tangles from forming.
• Schedule deep cleans monthly: Even if the brush looks clean, a thorough inspection ensures nothing is missed.

Conclusion

Cleaning your Eufy roller brush might seem like a small task, but it has a big impact on your vacuum’s performance, longevity, and your home’s cleanliness. With just a few minutes of effort each month, you can prevent clogs, protect the motor, and keep your floors spotless.

Remember: regular maintenance is always easier—and cheaper—than repairs. By following this guide, you’ll master the process and build a habit that keeps your Eufy running like new for years to come.
