Let’s get started!

Why Cleaning Your Eufy S1 Matters

Before diving into the steps, it’s important to understand why cleaning your Eufy S1 is so essential. Robot vacuums work hard—navigating around furniture, picking up dirt, and returning to their dock. Over time, this constant use leads to buildup in critical areas.

If you skip regular cleaning, you might notice:
– Reduced suction power
– Loud or unusual noises
– Frequent error messages
– Poor navigation or missed spots
– Shorter battery life

These issues aren’t just annoying—they can also shorten the life of your vacuum. For example, a clogged filter forces the motor to work harder, which can lead to overheating. Similarly, hair wrapped around the main brush can cause it to stop spinning, triggering error codes.

By cleaning your Eufy S1 regularly, you:
– Maintain strong suction
– Prevent motor strain
– Extend battery life
– Improve navigation accuracy
– Reduce the risk of breakdowns

Think of it like changing the oil in your car—small efforts now prevent big problems later. With just 10–15 minutes a week, you can keep your Eufy S1 performing at its peak.

What You’ll Need to Clean Your Eufy S1

Before you begin, gather these supplies. Most are probably already in your home:

• Soft, dry cloth or microfiber towel
• Mild soap or dish detergent (optional)
• Small brush (like a toothbrush or the included cleaning tool)
• Scissors or the cleaning tool’s built-in blade
• Compressed air (optional, for vents)
• Warm water
• Paper towels or a lint-free cloth

Avoid using harsh chemicals, bleach, or abrasive cleaners. These can damage plastic parts, degrade rubber seals, or leave residues that affect performance. Stick to gentle, non-abrasive methods.

Also, make sure your Eufy S1 is turned off and unplugged from the dock before cleaning. Safety first!

Step 1: Empty the Dustbin

The dustbin is the heart of your Eufy S1—it collects all the dirt, dust, and debris your vacuum picks up. If it’s full or clogged, suction drops dramatically.

How to Remove the Dustbin

1. Turn off your Eufy S1 and place it on a flat surface.
2. Flip the vacuum over so the bottom is facing up.
3. Locate the dustbin release button—it’s usually on the side or front of the unit.
4. Press the button and gently pull the dustbin straight out.

How to Empty the Dustbin

1. Hold the dustbin over a trash can.
2. Press the release latch to open the bottom lid.
3. Tap the bin gently to dislodge any stuck debris.
4. Use a dry cloth or brush to wipe away dust from the inside walls.

Pro tip: Empty the dustbin after every cleaning cycle, especially if you have pets or live in a dusty environment. Even if it’s not completely full, small particles can accumulate and reduce airflow.

Cleaning the Dustbin

While the dustbin is out, give it a quick wash:

1. Rinse it under warm water.
2. Use a mild soap if needed—just a drop on a cloth.
3. Scrub gently with a soft brush to remove sticky residue.
4. Rinse thoroughly to remove all soap.
5. Let it air dry completely—do not reinstall while wet.

Never put the dustbin in the dishwasher. The high heat can warp the plastic.

Step 2: Clean the Filters

The Eufy S1 uses a combination of a pre-motor filter and a HEPA filter to trap fine particles and allergens. These filters are essential for maintaining air quality and suction power.

Locating the Filters

The filters are housed inside the dustbin compartment. Once you remove the dustbin, you’ll see a filter tray at the top. Gently lift it out.

Removing and Cleaning the Filters

1. Take out both the pre-motor filter (usually foam or felt) and the HEPA filter.
2. Tap them gently over a trash can to remove loose dust.
3. Rinse the pre-motor filter under warm water. Do not use soap—it can degrade the material.
4. For the HEPA filter, rinse it gently under lukewarm water. Avoid scrubbing or squeezing.
5. Let both filters air dry for at least 24 hours. Do not use a hairdryer or place them in direct sunlight.

Important: Never wash the HEPA filter with soap or let it soak. Excess moisture can damage the fine fibers and reduce filtration efficiency.

When to Replace Filters

Eufy recommends replacing the HEPA filter every 3–6 months, depending on usage. If you have pets or allergies, replace it more often. Signs it’s time for a new filter include:
– Reduced suction
– Dust escaping from the vacuum
– A musty smell during operation

Always use genuine Eufy replacement filters for best performance.

Step 3: Clean the Main Brush and Side Brushes

Brushes are responsible for sweeping dirt into the suction path. Over time, hair, string, and debris can wrap around them, causing jams or reduced cleaning efficiency.

Removing the Main Brush

1. Flip the Eufy S1 over.
2. Locate the main brush cover—it’s held in place by clips or screws.
3. Use a coin or screwdriver to loosen the cover (if needed).
4. Lift the cover and pull out the main brush.

Cleaning the Main Brush

1. Use the cleaning tool’s built-in blade to cut through tangled hair.
2. Pull the hair and debris away from the brush rollers.
3. Wipe the brush with a damp cloth to remove dust.
4. Check the brush bearings for smooth rotation—clean any debris stuck there.

Pro tip: Clean the main brush weekly if you have long-haired pets. For short-haired pets or no pets, every two weeks is usually enough.

Cleaning the Side Brushes

The side brushes (usually two small brushes on the front corners) help sweep debris toward the main brush.

1. Gently pull the side brushes off their mounts.
2. Remove any hair or thread wrapped around the base.
3. Rinse them under water if needed, then let them dry.
4. Reattach securely—loose side brushes can cause navigation issues.

Step 4: Clean the Sensors and Camera

The Eufy S1 uses advanced sensors and a camera for navigation. If these get dirty, the vacuum may get stuck, miss spots, or fail to return to the dock.

Locating the Sensors

Key sensors include:
– Cliff sensors (on the bottom, near the wheels)
– Bumper sensors (on the front bumper)
– Camera lens (on the top, under the cover)
– Charging contacts (on the bottom)

Cleaning the Sensors

1. Use a soft, dry microfiber cloth to wipe the camera lens gently.
2. For cliff sensors, wipe the small circular lenses on the bottom.
3. Clean the front bumper with a damp cloth to remove dust and sticky residue.
4. Use a cotton swab lightly dampened with water to clean around the charging contacts.

Never use alcohol or cleaning sprays directly on sensors. If needed, lightly dampen the cloth—never the sensor itself.

Why Sensor Cleaning Matters

Dirty sensors can cause:
– False cliff detection (vacuum thinks it’s about to fall)
– Bumper not registering obstacles
– Camera misreading room layout
– Charging failure due to poor contact

A quick wipe every week can prevent these issues.

Step 5: Clean the Wheels and Vents

The wheels and vents are often overlooked, but they play a big role in performance and longevity.

Cleaning the Wheels

1. Flip the vacuum over.
2. Rotate each wheel and check for hair, thread, or debris wrapped around the axles.
3. Use scissors or the cleaning tool to cut and remove tangled material.
4. Wipe the wheels with a damp cloth to remove dirt.

If a wheel feels stiff or makes noise, it may need lubrication. However, Eufy does not recommend adding oil—instead, contact customer support if wheels are damaged.

Cleaning the Vents

The Eufy S1 has air vents on the sides and back to cool the motor.

1. Use a dry brush or compressed air to blow out dust from the vents.
2. Do not insert anything sharp into the vents—this can damage internal components.
3. Wipe the exterior with a dry cloth.

Blocked vents can cause overheating, especially during long cleaning sessions.

Step 6: Clean the Charging Dock (If Applicable)

If you have the Eufy S1 with a self-emptying dock or charging base, it also needs occasional cleaning.

Cleaning the Dock

1. Unplug the dock from the power source.
2. Wipe the exterior with a damp cloth.
3. Open the dust bag compartment (if self-emptying) and check for blockages.
4. Clean the charging pins on the dock with a dry cloth or cotton swab.
5. Ensure the dock’s airflow path is clear of dust and debris.

For self-emptying models, replace the dust bag when the indicator light turns red or every 2–3 months.

Troubleshooting Common Cleaning Issues

Even with regular maintenance, you might run into problems. Here’s how to fix the most common ones.

Problem: Vacuum Won’t Start After Cleaning

Make sure all parts are fully dry and properly reassembled. Check that the dustbin and filters are securely in place. If the vacuum still won’t start, try resetting it by holding the power button for 10 seconds.

Problem: Reduced Suction After Cleaning

This usually means the filter isn’t fully dry or the dustbin isn’t sealed properly. Double-check that the HEPA filter is completely dry and the dustbin clicks into place. Also, ensure the main brush spins freely.

Problem: Vacuum Gets Stuck or Misses Spots

Clean the camera lens and cliff sensors. Also, check that the side brushes are attached and spinning. If the issue persists, recalibrate the map in the Eufy app.

Problem: Unusual Noises During Operation

Listen for grinding or whining sounds. This could mean hair is wrapped around the brush or a wheel is obstructed. Turn off the vacuum and inspect the brushes and wheels.

Problem: Vacuum Doesn’t Return to Dock

Clean the charging contacts on both the vacuum and dock. Also, ensure the dock is placed on a flat, unobstructed surface with enough space around it.

How Often Should You Clean Your Eufy S1?

Consistency is key. Here’s a simple cleaning schedule:

• After every use: Empty the dustbin
• Weekly: Clean brushes, wipe sensors, check wheels
• Monthly: Wash filters, clean vents, inspect dock
• Every 3–6 months: Replace HEPA filter, deep-clean all parts

Adjust based on your home. Pet owners or homes with high foot traffic may need to clean more often.
