Whether you’re a first-time robot vacuum owner or just need a refresher, this guide is designed to be simple, clear, and practical. Let’s get started!

Why Cleaning the Filter Matters

Before diving into the cleaning process, it’s important to understand why cleaning the filter is so crucial. The filter in your Eufy 11s Max plays a vital role in the vacuum’s performance and your home’s air quality.

The Eufy 11s Max uses a high-efficiency particulate air (HEPA) filter, which is designed to trap tiny particles like dust, pollen, pet dander, and even some bacteria. As your vacuum runs, these particles accumulate on the filter. Over time, this buildup restricts airflow, forcing the motor to work harder to maintain suction. This not only reduces cleaning efficiency but can also lead to overheating and premature wear.

Additionally, a dirty filter can release trapped particles back into the air, especially when you empty the dustbin. This defeats the purpose of having a HEPA filter in the first place and can worsen allergies or asthma symptoms.

By cleaning the filter regularly—ideally every 2 to 4 weeks, depending on usage—you ensure that your Eufy 11s Max maintains strong suction, runs efficiently, and contributes to a healthier indoor environment.

What You’ll Need

Cleaning the filter on your Eufy 11s Max is a quick and easy task, but having the right tools on hand will make the process smoother. Here’s what you’ll need:

• A soft, dry cloth or microfiber towel
• A small brush (like a clean toothbrush or the cleaning tool that came with your vacuum)
• A bowl of lukewarm water (optional, for light rinsing—see notes below)
• A clean, dry towel or paper towels
• A well-lit, flat workspace (like a table or countertop)

Important: Avoid using soap, detergent, or any cleaning chemicals on the filter. These can degrade the HEPA material and reduce its effectiveness. Also, never use a hairdryer or heat source to speed up drying—this can warp or damage the filter.

Step 1: Turn Off and Unplug Your Eufy 11s Max

Safety first! Before you begin any maintenance on your robot vacuum, make sure it’s completely powered off and unplugged from the charging dock.

Even though the Eufy 11s Max is a battery-operated device, it’s still a good habit to ensure it’s not in standby or charging mode. This prevents accidental activation and protects both you and the device.

How to Power Down

• Press and hold the power button on the top of the vacuum until the lights turn off.
• If your vacuum is docked, remove it from the charging station.
• Place it on a flat, stable surface where you can work comfortably.

Once your Eufy 11s Max is safely powered down, you’re ready to move to the next step.

Step 2: Locate and Remove the Dustbin

The filter is housed inside the dustbin, so the first step is to remove the dustbin from the vacuum.

Finding the Dustbin

• Flip your Eufy 11s Max upside down so the bottom is facing up.
• Look for the rectangular dustbin compartment near the front of the vacuum, just behind the main brush roll.
• You’ll see a small latch or button on the side of the dustbin.

Removing the Dustbin

• Press the release button or slide the latch to unlock the dustbin.
• Gently pull the dustbin straight out from the vacuum.
• Set it aside on your workspace.

Now that the dustbin is out, you can access the filter inside.

Step 3: Remove the Filter from the Dustbin

Inside the dustbin, you’ll find the HEPA filter—a rectangular, sponge-like component that fits snugly into a slot at the top of the bin.

Accessing the Filter

• Open the dustbin lid by pressing the small tab on the front.
• Look inside—you’ll see the filter sitting in a designated compartment.
• The filter is usually held in place by a plastic frame or clips.

Carefully Extract the Filter

• Gently lift the filter out of its slot. It should come out easily with a slight tug.
• If it feels stuck, wiggle it slightly—don’t force it, as this could tear the material.
• Place the filter on a clean, dry surface.

Now that the filter is removed, you can inspect it and begin cleaning.

Step 4: Clean the Filter Thoroughly

This is the most important step in the entire process. Proper cleaning ensures your filter remains effective and your vacuum performs at its best.

Inspect the Filter First

• Hold the filter up to a light source. If you can’t see light through it, it’s likely clogged and needs cleaning.
• Check for visible dirt, hair, or debris trapped in the fibers.
• Look for signs of damage—tears, holes, or fraying edges mean it’s time to replace the filter.

Method 1: Dry Cleaning (Recommended for Routine Maintenance)

• Use a soft-bristled brush (like a clean toothbrush) to gently scrub the surface of the filter.
• Brush in one direction to loosen dust and particles.
• Tap the filter lightly over a trash can to dislodge any remaining debris.
• Use a dry microfiber cloth to wipe away any surface dust.

This method is ideal for weekly or bi-weekly cleaning and helps extend the life of your filter.

Method 2: Light Damp Cleaning (For Heavily Soiled Filters)

• If the filter is very dirty, you can rinse it under lukewarm water.
• Do not use hot water, as it can damage the HEPA material.
• Gently squeeze the filter under running water—do not twist or wring it.
• Rinse until the water runs clear, but avoid soaking the filter for long periods.

Important: Never use soap, detergent, or any cleaning agents. These can leave residues that reduce airflow and filter efficiency.

Let the Filter Dry Completely

• After cleaning, gently shake off excess water.
• Place the filter on a clean, dry towel or paper towels.
• Let it air dry in a well-ventilated area, away from direct sunlight or heat sources.
• Allow at least 12–24 hours for complete drying—never reinstall a damp filter.

Installing a wet or even slightly damp filter can lead to mold growth, unpleasant odors, and reduced suction power.

Step 5: Clean the Dustbin and Other Components

While the filter is drying, take the opportunity to clean the rest of the dustbin and related parts. This ensures your entire vacuum system stays in top condition.

Empty the Dustbin

• Open the dustbin lid and empty all contents into a trash can.
• Tap the bin gently to remove any stuck debris.

Wipe Down the Interior

• Use a damp cloth to wipe the inside of the dustbin.
• Focus on corners and crevices where dust tends to accumulate.
• Let the dustbin air dry completely before reassembling.

Check the Brush Roll and Side Brushes

• Remove the main brush roll by pressing the release clips on either end.
• Use scissors or the cleaning tool to cut away hair and string wrapped around the brush.
• Wipe the brush and housing with a dry cloth.
• Inspect the side brushes for wear and replace if bristles are bent or broken.

Cleaning these components regularly prevents clogs and ensures your Eufy 11s Max moves smoothly across all floor types.

Step 6: Reinstall the Filter and Dustbin

Once the filter is completely dry and all components are clean, it’s time to put everything back together.

Insert the Filter

• Place the clean, dry filter back into its slot inside the dustbin.
• Make sure it sits flat and secure—don’t force it.
• Close the dustbin lid until it clicks into place.

Reattach the Dustbin

• Align the dustbin with the compartment on the bottom of the vacuum.
• Slide it back into place until it locks with a click.
• Give it a gentle tug to ensure it’s securely attached.

Your Eufy 11s Max is now ready to go!

Step 7: Test Your Vacuum

Before resuming regular use, it’s a good idea to test your vacuum to make sure everything is working properly.

Run a Quick Cleaning Cycle

• Place your Eufy 11s Max on the floor in a small, open area.
• Press the clean button to start a short cleaning cycle.
• Listen for normal motor sounds and check that suction feels strong.
• Observe the vacuum’s movement—it should navigate smoothly without unusual noises.

If everything sounds and feels right, you’re all set. If you notice weak suction or strange sounds, double-check that the filter and dustbin are properly installed.

How Often Should You Clean the Filter?

The frequency of filter cleaning depends on several factors, including how often you use your vacuum, the type of flooring in your home, and whether you have pets.

Here’s a general guideline:

• Light use (1–2 times per week): Clean the filter every 4 weeks.
• Moderate use (3–4 times per week): Clean every 2–3 weeks.
