Make sure your robot vacuum is powered on and within Wi-Fi range. Follow the in-app setup instructions to pair your Eufy 11s with your smartphone. This usually involves pressing and holding the “Home” button on the robot until it beeps, then selecting your Wi-Fi network in the app.

Step 3: View Battery Status

Once connected, your Eufy 11s will appear on the app’s home screen. Tap on the device to open the control panel. Here, you’ll see a battery icon with a percentage—this shows the current charge level. For example, if it says “78%,” your robot has 78% battery remaining.

The app also shows whether the robot is currently charging, cleaning, or idle. If the battery is low (typically below 20%), the app may display a warning message and suggest returning to the dock.

Pro Tip: Enable Notifications

Turn on push notifications in the app settings so you’ll be alerted when the battery is low or when cleaning is complete. This helps you stay informed without constantly checking the app.

Method 2: Check Eufy 11s Battery Using LED Indicators

If you don’t have your phone handy, the Eufy 11s has built-in LED lights that convey battery status through color and blinking patterns. These visual cues are especially helpful during setup or when the app isn’t accessible.

Understanding LED Colors and Patterns

The LED ring around the power button changes color based on the robot’s status:

• Solid Blue: The robot is fully charged and ready to clean.
• Blinking Blue: The robot is charging. The light will blink slowly while charging and turn solid once full.
• Solid Red: The battery is critically low (usually below 10%). The robot may not start cleaning and will need to return to the dock.
• Blinking Red: There’s a charging error or the battery is too low to operate. This could indicate a problem with the dock, power supply, or battery itself.
• Solid Orange: The robot is in standby mode or paused during cleaning.
• Blinking Orange: The robot is returning to the charging dock automatically due to low battery.

How to Use LED Indicators to Check Battery

To check the battery using the LED:
1. Look at the light ring on top of the robot.
2. Note the color and whether it’s solid or blinking.
3. Match the pattern to the list above to determine battery status.

For example, if the light is blinking blue, your Eufy 11s is charging. If it’s solid red, plug it in immediately.

Pro Tip: Check the Dock’s LED Too

The charging dock also has an LED light. A solid blue light means it’s powered and ready. If the dock light is off or red, check the power adapter and outlet.

Method 3: Listen for Voice Alerts

The Eufy 11s uses voice prompts to communicate important status updates, including battery levels. These spoken alerts are helpful if you’re nearby but not looking at the robot or app.

Common Voice Alerts Related to Battery

• “Battery low, returning to dock.” This means the battery has dropped below the threshold (usually 15–20%), and the robot is navigating back to charge.
• “Charging.” Spoken when the robot successfully docks and begins charging.
• “Charging complete.” Announced when the battery reaches 100%.
• “Please place me on the dock.” If the robot is low on battery but can’t find the dock, it will ask for help.

How to Use Voice Alerts to Monitor Battery

Simply listen for these phrases during or after cleaning. If you hear “Battery low,” check the app or LED to confirm. If the robot says “Charging complete,” you know it’s ready for the next task.

Pro Tip: Adjust Volume or Disable Voice Alerts

If the voice prompts are too loud or unnecessary, you can adjust the volume or turn them off in the EufyHome app under “Device Settings” > “Voice Prompt.”

Method 4: Manual Battery Check (Without App or Wi-Fi)

If your Eufy 11s isn’t connected to Wi-Fi or the app isn’t working, you can still get a rough idea of battery level through behavior and timing.

Observe Cleaning Performance

A healthy battery allows the Eufy 11s to clean for about 100 minutes on a full charge. If your robot:
– Stops cleaning after 30–40 minutes
– Struggles to move or loses suction
– Frequently returns to dock mid-clean

These signs suggest the battery may be weak or degraded.

Time the Charging Cycle

A full charge typically takes 3–4 hours. If your robot charges in under 2 hours but dies quickly, the battery may not be holding a charge well. Conversely, if it takes longer than 5 hours to charge, there could be a charging issue.

Check Physical Signs

Inspect the robot for:
– Swollen or bulging battery compartment (rare but serious)
– Excessive heat after charging
– Unusual smells

These could indicate a failing battery and should be addressed immediately.

Tips for Maintaining Eufy 11s Battery Health

Checking the battery is only half the battle—keeping it healthy ensures long-term performance. Follow these best practices to extend battery life.

Keep It Charged (But Not Overcharged)

Lithium-ion batteries, like the one in the Eufy 11s, last longest when kept between 20% and 80% charge. However, it’s safe to leave the robot on the dock when not in use. The Eufy 11s is designed to stop charging once full, preventing overcharging.

Avoid Deep Discharges

Letting the battery drain completely before recharging can stress the cells. Try to recharge when the battery drops below 30%.

Clean Charging Contacts Monthly

Dust and hair can build up on the charging pins on both the robot and dock. Use a dry cotton swab or soft cloth to gently clean them. Dirty contacts can prevent proper charging, leading to false low-battery readings.

Store in a Cool, Dry Place

High temperatures degrade battery life. Avoid leaving the Eufy 11s in hot cars or near heaters. Ideal storage temperature is between 32°F and 77°F (0°C to 25°C).

Update Firmware Regularly

Eufy releases firmware updates that improve battery management, navigation, and performance. Check for updates in the EufyHome app under “Device Settings” > “Firmware Update.”

Use Original Charging Accessories

Always use the original charging dock and power adapter. Third-party chargers may not deliver the correct voltage, damaging the battery over time.
