Changing the brushes on your Eufy Robovac 11 is a simple maintenance task that ensures optimal cleaning performance. This guide walks you through the entire process, from identifying worn brushes to installing new ones, helping you extend your robot vacuum’s lifespan.

Key Takeaways

Introduction: Why Brush Maintenance Matters

Your Eufy Robovac 11 is a smart, efficient cleaning companion—but like any machine, it needs regular care to perform at its best. One of the most important maintenance tasks is replacing the brushes. Over time, the main roller brush and side brush wear down, collect hair and debris, and lose their effectiveness. If you’ve noticed your Robovac 11 struggling to pick up dirt, making unusual noises, or leaving streaks on your floors, it might be time for a brush change.

In this comprehensive guide, we’ll walk you through how to change the brushes on Eufy Robovac 11 step by step. Whether you’re a first-time robot vacuum owner or a seasoned user, this tutorial will help you keep your device in top shape. You’ll learn how to identify worn brushes, safely remove the old ones, install new replacements, and maintain your vacuum for long-term performance.

By the end of this guide, you’ll have the confidence and knowledge to perform this essential maintenance task quickly and correctly—no technical expertise required.

What You’ll Need Before Starting

Before diving into the brush replacement process, it’s important to gather the right tools and materials. Fortunately, you won’t need anything fancy—just a few basic items that are likely already in your home.

Tools and Supplies Checklist

• Phillips-head screwdriver: This is essential for removing the brush cover. A small to medium-sized screwdriver works best.
• Clean, dry cloth: Use this to wipe down the brush housing and remove dust or debris.
• Replacement brushes: Purchase genuine Eufy Robovac 11 replacement brushes. These include the main roller brush and the side brush. You can find them on the official Eufy website, Amazon, or authorized retailers.
• Scissors or tweezers (optional): Helpful for removing tangled hair or string from the brush housing.
• Small bowl or tray: Use this to hold screws and small parts so you don’t lose them.

Why Genuine Parts Matter

While third-party brushes may be cheaper, they often don’t fit as well or last as long as genuine Eufy parts. Using non-OEM (original equipment manufacturer) brushes can lead to poor performance, increased wear on the motor, and even void your warranty. Genuine Eufy brushes are designed specifically for the Robovac 11’s dimensions and cleaning needs, ensuring a snug fit and reliable operation.

When to Replace the Brushes

You don’t need to wait until the brushes are completely destroyed. Here are some signs it’s time for a change:

• The main brush shows visible fraying, cracks, or missing bristles.
• The side brush spins sluggishly or not at all.
• Your Robovac 11 is leaving behind dirt, especially along edges and corners.
• You hear grinding or squeaking noises during operation.
• It’s been 3–6 months since your last brush replacement (depending on usage).

Regular inspection helps you stay ahead of wear and tear. Make it a habit to check the brushes every time you empty the dustbin.

Step-by-Step Guide: How to Change the Brushes on Eufy Robovac 11

Now that you’re prepared, let’s get into the actual process. Changing the brushes on your Eufy Robovac 11 is straightforward and should take no more than 10–15 minutes.

Step 1: Power Off and Flip the Vacuum

Safety first! Before handling any internal components, make sure your Robovac 11 is completely powered off. Press and hold the power button until the device shuts down. Then, unplug it from any charging dock.

Next, flip the vacuum over so the bottom side is facing up. Place it on a clean, flat surface like a table or countertop. This gives you easy access to the brush compartment.

Step 2: Remove the Brush Cover

Locate the brush cover on the underside of the vacuum. It’s a rectangular plastic panel held in place by two Phillips-head screws—one on each end.

Use your screwdriver to carefully remove both screws. Place them in your small bowl or tray so they don’t get lost. Once the screws are out, gently lift the brush cover away from the vacuum. It should come off easily, but don’t force it—there may be a slight clip or tab holding it in place.

Step 3: Remove the Old Main Brush

With the cover off, you’ll see the main roller brush inside the brush housing. This is the long, cylindrical brush that rotates to sweep dirt into the suction path.

To remove it, gently pull the brush out from one side. It’s held in place by a small plastic bracket on each end. You may need to wiggle it slightly to free it from the housing. Be careful not to damage the surrounding components.

Once the brush is out, inspect it for wear. If it’s frayed, cracked, or missing bristles, it’s definitely time for a replacement.

Step 4: Clean the Brush Housing

Before installing the new brush, take a moment to clean the brush housing. Over time, hair, string, and dust can accumulate around the brush area, causing clogs and reducing performance.

Use your fingers, tweezers, or scissors to remove any tangled debris. Wipe the inside of the housing with a dry cloth to remove dust and dirt. This simple step helps prevent future issues and keeps your vacuum running smoothly.

Step 5: Install the New Main Brush

Take your new main brush (make sure it’s the correct model for the Robovac 11) and align it with the brush housing. Slide one end into the bracket, then gently press the other end into place. It should fit snugly and rotate freely when you spin it by hand.

Double-check that the brush is seated properly and not crooked. A misaligned brush can cause noise, reduced suction, or even damage the motor.

Step 6: Replace the Brush Cover

Once the new main brush is in place, it’s time to reattach the brush cover. Align the cover with the housing and press it down gently. Make sure it sits flush with the bottom of the vacuum.

Insert the two screws back into their holes and tighten them with your screwdriver. Don’t overtighten—just snug them up so the cover is secure.

Step 7: Replace the Side Brush

Now let’s move on to the side brush, which is located near the front corner of the vacuum. This small, star-shaped brush helps sweep debris from edges and corners into the vacuum’s path.

The side brush is held in place by a single screw. Use your screwdriver to remove it. Once the screw is out, gently pull the old side brush off the motor shaft.

Take your new side brush and slide it onto the motor shaft. Make sure it’s oriented correctly—the bristles should face outward. Reinsert the screw and tighten it securely.

Step 8: Final Inspection and Testing

With both brushes replaced, give your Robovac 11 a quick visual check. Ensure all screws are tight, the brush cover is secure, and nothing looks loose or misaligned.

Flip the vacuum back over and place it on the floor. Power it on and run a short cleaning cycle—just a few minutes on a small area. Listen for any unusual noises and watch to see if the brushes are spinning properly.

If everything looks and sounds good, you’re all set! Your Eufy Robovac 11 is now ready to tackle dirt and debris with renewed efficiency.

Tips for Maintaining Your Eufy Robovac 11 Brushes

Replacing the brushes is just one part of keeping your robot vacuum in great condition. Here are some additional tips to extend the life of your brushes and improve overall performance.

Clean the Brushes Between Replacements

Even if the brushes aren’t due for replacement, they can collect hair and debris that affects performance. Every 1–2 weeks, remove the main brush and use scissors or a seam ripper to cut away tangled hair. Wipe the brush and housing with a dry cloth.

For the side brush, simply unscrew it and clean off any wrapped hair. A clean brush spins more freely and picks up more dirt.

Check for Obstructions Regularly

Before and after each cleaning cycle, take a quick look at the brush area. Make sure nothing is stuck in the rollers or around the side brush. Common culprits include pet hair, string, and small toys.

Adjust Cleaning Frequency Based on Usage

If you have pets, kids, or high foot traffic, your Robovac 11 will get dirtier faster. Consider running it daily and checking the brushes weekly. In low-traffic homes, weekly cleaning and monthly brush checks may be sufficient.

Store Your Vacuum Properly

When not in use, keep your Robovac 11 on its charging dock in a dry, dust-free area. Avoid storing it in humid or dirty environments, as this can accelerate brush wear.

Keep Spare Brushes on Hand

It’s always a good idea to have a set of replacement brushes ready. That way, when you notice wear, you can swap them out immediately without waiting for a delivery.

Troubleshooting Common Issues

Even with proper maintenance, you might encounter a few hiccups. Here’s how to address some common problems related to brush replacement.

Brush Won’t Spin After Replacement

If the main or side brush isn’t spinning, double-check the installation. Make sure the main brush is seated correctly in the housing and the side brush is securely attached to the motor shaft. Also, ensure there’s no debris blocking the rotation.

If the brush still doesn’t spin, the motor may be faulty. Contact Eufy customer support for assistance.

Vacuum Makes Grinding or Squeaking Noises

This usually indicates a problem with the brush or motor. Remove the brush and inspect it for damage. Check the housing for debris. If the noise persists, the motor bearings may be worn—again, contact Eufy for help.

New Brush Doesn’t Fit Properly

If your replacement brush doesn’t fit, confirm you’ve purchased the correct model. Eufy offers different brush sets for various Robovac models. The Robovac 11 uses a specific brush size—double-check the product description before buying.

Brush Cover Won’t Stay On

If the cover feels loose or won’t snap into place, make sure the main brush is fully inserted and not pushing against the cover. Also, verify that the screws are tightened evenly.
