We’ll cover everything from identifying when it’s time for a replacement to safely removing old brushes and installing new ones. You’ll also get practical tips for cleaning the brush housing, troubleshooting common issues, and maintaining your Eufy for long-term reliability.

Whether you’re dealing with pet hair, high-traffic areas, or just want to keep your floors spotless, this guide will make brush replacement quick, easy, and stress-free.

Why Changing Brushes Matters

Before diving into the steps, it’s important to understand why brush maintenance is so crucial. The brushes on your Eufy robot vacuum are the first line of defense against dirt, dust, and debris. The main roller brush (also called the main brush or roller) agitates and lifts dirt from carpets and hard floors, while the side brushes (or side sweepers) push debris from edges and corners into the vacuum’s path.

When these brushes wear down or get clogged, your Eufy can’t clean effectively. You might notice:
– Reduced suction power
– Uneven cleaning patterns
– Scratching or scuffing on floors
– The robot getting stuck or skipping areas
– Increased noise during operation

Replacing worn brushes restores cleaning performance and protects your floors and vacuum motor. It’s a simple task that can make a big difference in your home’s cleanliness and your Eufy’s longevity.

When to Replace Eufy Brushes

So, how do you know it’s time to change the brushes? Here are the most common signs:

• Visible wear: Look for frayed bristles, flattened rubber flaps, or cracks in the brush roller.
• Tangling: Hair, string, or pet fur wrapped tightly around the brush can prevent it from spinning freely.
• Reduced cleaning performance: If your Eufy isn’t picking up dirt as well as it used to, the brushes may be the culprit.
• Unusual noises: Grinding, clicking, or squeaking sounds often indicate a jammed or damaged brush.
• Brush stops spinning: If the main brush or side brushes don’t rotate during operation, they likely need replacement.

As a general rule, inspect your brushes every month. For homes with pets or high foot traffic, consider checking every two weeks. Most Eufy users should replace brushes every 6 to 12 months, but this can vary based on usage.

Tools and Materials You’ll Need

The good news? You don’t need a full toolbox to change Eufy brushes. Here’s what you’ll typically need:

• Replacement brushes: Purchase genuine Eufy replacement parts for your specific model (e.g., RoboVac 11S, 30C, G30, etc.). These are available on the Eufy website, Amazon, or authorized retailers.
• Phillips head screwdriver: Most Eufy models use small Phillips screws to secure the brush cover.
• Scissors or tweezers: Useful for cutting away tangled hair or debris.
• Soft cloth or brush: For cleaning the brush housing and removing dust.
• Small container: To hold screws so you don’t lose them.

Always use genuine Eufy replacement brushes. While third-party options may be cheaper, they often don’t fit properly, wear out faster, or can void your warranty. Genuine parts ensure compatibility and optimal performance.

Step-by-Step: How to Change Brushes on Eufy

Now, let’s walk through the process of changing the brushes on your Eufy robot vacuum. The steps are similar across most models, but we’ll highlight any key differences.

Step 1: Power Off and Prepare Your Workspace

Before you begin, make sure your Eufy is completely powered off. If it’s on the charging dock, remove it and press the power button to turn it off. Never attempt to change brushes while the robot is running or charging—this is a safety precaution to avoid injury or damage.

Place your Eufy on a flat, well-lit surface, such as a table or the floor. Have your tools and replacement brushes within reach. It’s also a good idea to lay down a soft cloth or towel to protect the robot’s surface from scratches.

Step 2: Remove the Brush Cover

Flip your Eufy over so the underside is facing up. You’ll see the main roller brush covered by a plastic or metal guard. This cover is held in place by one or two screws, depending on your model.

Use your Phillips head screwdriver to carefully remove the screws. Place them in a small container so you don’t lose them. Once the screws are out, gently lift the brush cover. Some models have a clip or hinge, so don’t force it—wiggle it slightly if needed.

Step 3: Remove the Old Main Brush

With the cover off, you’ll see the main roller brush. This is usually a long, cylindrical brush with rubber flaps and bristles. It’s held in place by two end caps or brackets—one on each side.

To remove the brush:
– Gently pull one end cap out of its slot.
– Slide the brush out from the opposite side.
– If the brush is stuck due to hair or debris, use scissors or tweezers to carefully cut away any tangled material.

Inspect the brush for wear. If the rubber flaps are flattened, cracked, or missing, or if the bristles are frayed, it’s definitely time for a replacement.

Step 4: Clean the Brush Housing

While the brush is out, take a moment to clean the brush housing. Use a soft cloth or small brush to remove dust, hair, and debris from the compartment. Pay special attention to the brush motor area and the slots where the end caps sit.

This step is often overlooked, but it’s essential. A clean housing ensures the new brush spins freely and prevents future clogs. If you see a lot of buildup, you can use a damp cloth (lightly moistened) to wipe down the area—just make sure it’s completely dry before reassembling.

Step 5: Install the New Main Brush

Take your new Eufy main brush and align it with the housing. Insert one end cap into its slot, then gently slide the brush into place. Push the other end cap into position until it clicks or sits securely.

Make sure the brush rotates freely by giving it a gentle spin with your finger. If it’s stiff or doesn’t move, double-check that it’s properly seated and that no debris is blocking it.

Step 6: Reattach the Brush Cover

Once the new brush is in place, reposition the brush cover over the housing. Align the screw holes and gently press down to secure it. Insert the screws and tighten them with your screwdriver—don’t overtighten, as this can strip the screws or crack the plastic.

Step 7: Replace the Side Brushes (If Needed)

Now, let’s move on to the side brushes. These are the small, triangular brushes located on the front corners of your Eufy. They’re usually held in place by a single screw.

To replace a side brush:
– Use your screwdriver to remove the screw.
– Lift off the old brush.
– Position the new brush so the screw hole aligns with the mounting post.
– Secure it with the screw and tighten gently.

Most Eufy models have two side brushes, so repeat this process for the other side if needed. Side brushes tend to wear out faster than the main brush, especially in homes with pets or lots of edge cleaning.

Step 8: Test Your Eufy

Once all brushes are replaced, it’s time to test your robot. Place it on the floor and press the power button. Let it run for a few minutes to ensure the brushes are spinning properly and there are no unusual noises.

If everything looks and sounds good, return your Eufy to its charging dock. It will resume normal operation and begin cleaning with improved efficiency.

Model-Specific Tips

While the general process is similar across Eufy models, there are a few differences to note:

• RoboVac 11S: Uses a single main brush with rubber flaps. The brush cover is held by two screws. Side brushes are easy to replace with one screw each.
• RoboVac 30C: Similar to the 11S but includes Wi-Fi connectivity. Brush replacement process is identical.
• RoboVac G30: Features a dual rubber roller system. The brush cover may have a slightly different design, but removal is the same—unscrew, lift, and replace.
• RoboVac L35 Hybrid: Includes a mopping function. Be extra careful not to get water or cleaning solution on the brush housing during cleaning.

Always refer to your user manual for model-specific instructions. If you’ve misplaced yours, you can download a copy from the Eufy website.

Troubleshooting Common Issues

Even with careful installation, you might run into a few hiccups. Here’s how to handle common problems:

Brush Doesn’t Spin After Replacement

If the new brush isn’t spinning, check the following:
– Is the brush properly seated in the housing?
– Are the end caps securely in place?
– Is there debris blocking the brush or motor?
– Did you install the correct brush for your model?

Try removing and reinstalling the brush. If it still doesn’t spin, contact Eufy support—there may be an issue with the motor.

Screws Won’t Tighten or Keep Falling Out

This usually means the screw holes are stripped. Try using a slightly larger screw or adding a small piece of tape to the screw threads for a tighter fit. Avoid overtightening in the future.

Side Brush Wobbles or Falls Off

Ensure the screw is tight and the brush is aligned correctly. If the mounting post is damaged, you may need a replacement part.

Unusual Noise During Operation

Grinding or clicking sounds could indicate a foreign object in the brush housing or a misaligned brush. Power off the robot, inspect the brushes, and remove any debris.

Maintenance Tips for Longer Brush Life

Replacing brushes is important, but so is regular maintenance. Here are some tips to extend the life of your Eufy brushes:

• Clean brushes monthly: Even if they don’t need replacing, remove hair and debris to prevent tangling.
• Check for obstructions: After each cleaning cycle, inspect the brush housing for stuck objects.
• Avoid wet floors: Eufy robots are not designed for wet cleaning. Moisture can damage brushes and motors.
• Use on appropriate surfaces: Avoid thick rugs or uneven flooring that can strain the brushes.
• Store properly: Keep your Eufy in a dry, dust-free area when not in use.

By following these habits, you’ll reduce wear and tear and get the most out of every brush replacement.

Where to Buy Genuine Eufy Replacement Brushes

To ensure compatibility and performance, always buy genuine Eufy replacement brushes. Here are the best places to shop:

• Eufy Official Website: Offers the full range of parts with warranty coverage.
• Amazon: Look for listings marked “Sold by Eufy” or “Fulfilled by Amazon” to avoid counterfeit products.
• Authorized Retailers: Stores like Best Buy or Walmart often carry Eufy accessories.

When purchasing, double-check the model number of your Eufy (found on the bottom of the robot or in the app) to ensure you get the right brushes.
