Why Calibrate Your Eufy Robovac?

Calibration is the process of resetting and aligning your Robovac’s internal sensors and navigation system. Think of it like recalibrating a GPS after a long trip—your vacuum needs to “relearn” its surroundings to move accurately.

Here’s why calibration is important:

• Improved Navigation: Calibration helps the Robovac create accurate maps of your home. This means fewer missed spots and less backtracking.
• Better Obstacle Detection: Sensors detect furniture, cords, and stairs. Calibration ensures they respond correctly.
• Smoother Movement: A well-calibrated vacuum moves in straight lines and turns smoothly, instead of wobbling or getting stuck.
• Enhanced Battery Efficiency: When the vacuum knows where it is, it doesn’t waste time or power retracing steps.
• Post-Update Optimization: After firmware updates, calibration ensures new features work as intended.

Without regular calibration, your Robovac might develop “drift”—a gradual loss of accuracy in its movement and mapping. This can lead to frustration, especially if you rely on scheduled cleanings or room-specific settings.

When Should You Calibrate Your Eufy Robovac?

You don’t need to calibrate your Robovac every week, but there are certain situations when it’s essential:

• First-Time Setup: Always calibrate a new Robovac before its first cleaning cycle.
• After Moving the Vacuum: If you’ve relocated the vacuum to a new home or a different floor, recalibrate it.
• Following a Firmware Update: Updates can change how sensors operate. Calibration ensures compatibility.
• After Cleaning or Maintenance: If you’ve removed and reattached wheels, brushes, or sensors, recalibration helps the system sync.
• Performance Issues: If your Robovac is getting stuck, missing areas, or showing error messages, calibration may resolve the problem.
• Seasonal Changes: If you’ve rearranged furniture or added rugs, recalibration helps the vacuum adapt.

As a general rule, consider calibrating your Robovac every 3–6 months, or whenever you notice a drop in performance.

What You’ll Need Before You Start

Before beginning the calibration process, gather these items to ensure a smooth experience:

• Eufy Robovac: Fully charged and powered on.
• Smartphone or Tablet: With the EufyHome app installed and logged in.
• Wi-Fi Connection: Stable internet access for app communication.
• Clean, Open Space: A flat area with at least 3 feet of clearance around the vacuum.
• Soft Cloth or Brush: For cleaning sensors (optional but recommended).
• Owner’s Manual: For model-specific details (available in the app or online).

Make sure the vacuum is on a hard, flat surface—avoid thick rugs or uneven flooring during calibration. Also, remove any obstacles like shoes, cables, or pet toys from the area.

Step-by-Step Guide: How to Calibrate a Eufy Robovac

Now that you’re prepared, let’s walk through the calibration process. We’ll use the EufyHome app, which is the easiest and most reliable method for most Eufy Robovac models, including the RoboVac 11S, 30C, G30, and L70 Hybrid.

Step 1: Charge Your Robovac Fully

Start by ensuring your Robovac has a full charge. A low battery can interrupt calibration or cause errors. Place the vacuum on its charging dock and wait until the indicator light shows it’s fully charged (usually a solid green or blue light).

While it charges, take a moment to clean the sensors and wheels. Use a soft, dry cloth to wipe the cliff sensors (on the bottom), the bumper sensor (front), and the charging contacts. This helps the vacuum detect its environment accurately during calibration.

Step 2: Open the EufyHome App

Launch the EufyHome app on your smartphone or tablet. If you haven’t set up your Robovac yet, follow the initial setup prompts to connect it to your Wi-Fi network. Make sure your phone is connected to the same Wi-Fi network as your vacuum.

Once logged in, tap on your Robovac from the device list. You should see a dashboard with options like “Clean,” “Schedule,” “Map,” and “Settings.”

Step 3: Access the Calibration Menu

Tap the Settings icon (usually a gear or three dots) in the top-right corner of the screen. Scroll down until you find an option labeled “Calibration” or “Sensor Calibration.” Not all models have this labeled the same way—on some, it may be under “Advanced Settings” or “Maintenance.”

If you don’t see a calibration option, your model may require a different method. Check the troubleshooting section below for alternatives.

Step 4: Begin the Calibration Process

Tap “Start Calibration” or “Begin Sensor Calibration.” The app will display instructions and may ask you to confirm that the vacuum is on a flat surface and free of obstacles.

The Robovac will then begin moving slowly in a small circle or straight line. This allows it to test its wheels, gyroscope, and cliff sensors. You’ll see a progress bar in the app indicating how far along the process is.

Do not touch or move the vacuum during this time. Let it complete the full cycle, which usually takes 1–3 minutes.

Step 5: Confirm Calibration Success

Once the process finishes, the app will display a message like “Calibration Complete” or “Sensors Aligned.” If successful, you’ll see a green checkmark or confirmation screen.

If the calibration fails, the app may show an error message. Common reasons include low battery, blocked sensors, or unstable Wi-Fi. We’ll cover how to fix these in the troubleshooting section.

Step 6: Test the Vacuum

After calibration, run a short cleaning test. Tap “Clean” in the app and let the Robovac operate for 5–10 minutes in a small area, like a hallway or living room.

Watch how it moves. Does it travel in straight lines? Does it avoid obstacles smoothly? Does it return to the dock correctly? If everything looks good, your calibration was successful.

Alternative Calibration Methods

Not all Eufy Robovac models support app-based calibration. Some older or budget models may require manual methods. Here are two common alternatives:

Manual Wheel Calibration (For Models Without App Support)

If your Robovac doesn’t have a calibration option in the app, you can perform a manual wheel reset:

• Power off the vacuum.
• Remove the side brush and main brush.
• Flip the vacuum over and gently rotate each wheel 10–15 times in both directions.
• This helps reset the wheel encoders and improve tracking accuracy.
• Reassemble the brushes and power on the vacuum.
• Run a test cleaning cycle to check performance.

Factory Reset + Re-Setup

If calibration fails repeatedly, a factory reset may be necessary. This erases all settings and returns the vacuum to its original state. After resetting, you’ll need to reconnect it to Wi-Fi and set up schedules and maps again.

To factory reset:

• Press and hold the Home and Spot buttons simultaneously for 10 seconds.
• The vacuum will beep and restart.
• Open the EufyHome app and follow the setup process as if it were new.
• Complete calibration during setup.

Note: A factory reset should be a last resort, as it deletes all saved maps and preferences.

Troubleshooting Common Calibration Issues

Even with careful steps, calibration can sometimes fail. Here’s how to fix the most common problems:

Calibration Fails or Stops Midway

Possible Causes:

• Low battery
• Blocked sensors
• Unstable Wi-Fi
• Obstacles in the path

Solutions:

• Ensure the vacuum is fully charged.
• Clean all sensors with a dry cloth.
• Move closer to your Wi-Fi router or restart it.
• Clear the area around the vacuum.
• Restart the app and try calibration again.

Vacuum Wobbles or Drifts During Calibration

This usually indicates a wheel or sensor issue.

Check the following:

• Are the wheels spinning freely? Remove debris from wheel wells.
• Is the main brush tangled? Clean it thoroughly.
• Are the cliff sensors dirty? Wipe them gently.
• Is the floor too slippery? Avoid polished marble or wet surfaces.

If the problem persists, try recalibrating on a different surface, like a hardwood floor.

App Doesn’t Show Calibration Option

Some Eufy models, especially older ones, don’t support app-based calibration.

What to do:

• Check your model number in the app or on the vacuum.
• Visit the Eufy support website and search for your model’s manual.
• Use the manual wheel method described above.
• Contact Eufy customer support for model-specific guidance.

Calibration Succeeds, But Performance Doesn’t Improve

If your Robovac still misses spots or gets stuck after calibration, the issue may not be navigation—it could be mechanical or environmental.

Try these fixes:

• Update the firmware via the app (Settings > Firmware Update).
• Reset the map in the app (Map > Reset Map).
• Rearrange furniture to create clearer pathways.
• Use boundary strips to block off problem areas.
• Schedule more frequent cleanings to prevent debris buildup.

Tips for Maintaining Calibration Accuracy

Calibration isn’t a one-and-done task. To keep your Robovac performing well, follow these maintenance tips:

• Clean Sensors Weekly: Wipe cliff sensors, bumpers, and charging contacts with a dry cloth.
• Check Wheels Monthly: Remove hair and debris from wheel axles to prevent slipping.
• Replace Brushes as Needed: Worn brushes can affect movement and sensor feedback.
• Update Firmware Regularly: New updates often include navigation improvements.
• Avoid Moving the Vacuum Mid-Clean: If you pick it up, place it back gently to avoid confusing the map.
• Use Consistent Dock Placement: Keep the charging dock in the same spot to help the vacuum orient itself.

By staying proactive, you’ll reduce the need for frequent recalibrations and extend your Robovac’s lifespan.
