Let’s dive in!

Understanding Your Robovac Eufy’s Charging System

Before we get into the how-to, it’s helpful to understand how the charging system works. Most Eufy Robovac models—like the Robovac 11S, 30C, 15C, and G30—use a lithium-ion battery and a wireless charging dock. The robot navigates back to the dock using infrared sensors and physical contact points. Once it docks, power flows from the dock to the robot’s battery through metal charging contacts.

The charging process is automatic in most cases. When the battery drops below a certain level (usually around 20–30%), the robot will pause cleaning and return to the dock. Once docked, it begins charging. A full charge typically takes 2.5 to 4 hours, depending on the model and battery capacity.

It’s important to note that Eufy Robovacs are designed to stay on the dock when not in use. This keeps the battery topped off and ensures the robot is always ready for the next cleaning cycle. Unlike some other robot vacuums, Eufy models don’t support “trickle charging” or continuous low-power charging, so they’ll charge fully and then stop until the battery begins to drain again.

Step 1: Unbox and Inspect Your Robovac Eufy

Before you start charging, take a moment to unbox your Robovac and inspect all components. You should have:

– The Robovac unit
– Charging dock
– Power adapter
– Side brushes (usually pre-installed)
– User manual

Make sure nothing is damaged during shipping. Check the charging contacts on both the robot and the dock—these are small metal strips usually located on the bottom or rear of the robot and on the front of the dock. They should be clean and free of debris.

If you’re setting up a used or refurbished unit, wipe down the contacts with a dry cloth to remove any dust or residue.

Step 2: Set Up the Charging Dock

Proper placement of the charging dock is crucial for reliable charging. Here’s how to do it right:

Choose the Right Location

Pick a spot that’s:
– Flat and level (avoid carpets or uneven flooring)
– At least 1.5 feet (45 cm) away from walls, furniture, or obstacles
– In a well-lit area (some models use visual cues to locate the dock)
– Away from direct sunlight, heat sources, or moisture

Avoid placing the dock in a dark corner or behind furniture. The robot uses sensors to “see” the dock, and obstacles can block its path.

Plug In the Dock

Connect the power adapter to the dock and plug it into a wall outlet. The dock’s indicator light should turn on—usually green or blue—to show it’s receiving power.

Don’t use extension cords or power strips if possible. A direct wall outlet ensures stable power delivery.

Test the Dock

Place your Robovac on the dock manually to see if it connects. The robot should align with the charging contacts, and the dock light may blink or change color to indicate charging has started.

If the robot doesn’t recognize the dock, double-check the placement and ensure the contacts are clean.

Step 3: Charge Your Robovac for the First Time

New Robovac units often ship with a partial charge—enough to power on and run a short test, but not enough for a full cleaning cycle. For best results, charge your robot fully before using it.

Place the Robot on the Dock

Gently align the robot’s charging contacts with those on the dock. The rear of the robot should face the dock, and the wheels should rest on the dock’s platform.

You’ll hear a soft click or see the robot shift slightly when it’s properly seated.

Wait for Charging to Begin

Once docked, the robot’s display (if it has one) will show a charging icon or light. On models without a screen, the dock’s light may blink or turn solid to indicate charging.

A full charge typically takes 2.5 to 4 hours. Avoid interrupting the charge during this time.

Check the Battery Level

After charging, press the power button or check the app (if your model supports it) to confirm the battery is at 100%. This ensures the robot is ready for its first cleaning run.

Step 4: Enable Auto-Return to Dock

One of the best features of the Robovac Eufy is its ability to return to the dock automatically when the battery is low. Make sure this feature is enabled so your robot doesn’t get stranded mid-clean.

Using the Physical Buttons

On most Eufy models, the auto-return feature is enabled by default. However, you can confirm it by:
– Pressing and holding the “Dock” or “Home” button for 3 seconds
– Watching for a confirmation beep or light flash

Using the Eufy Clean App

If your model supports the app (like the Robovac 30C or G30), follow these steps:
– Download and open the Eufy Clean app
– Connect your Robovac to Wi-Fi
– Go to “Device Settings” > “Cleaning Settings”
– Ensure “Auto Return to Dock” is turned on

This feature ensures your robot will pause cleaning and head back to charge when the battery drops below 20–30%, then resume cleaning once charged (if you’ve enabled “Resume Cleaning”).

Step 5: Maintain Proper Charging Habits

How you charge your Robovac affects its long-term battery health. Follow these best practices:

Keep It on the Dock When Not in Use

Always return your Robovac to the dock after cleaning. This keeps the battery topped off and ready for the next cycle. Lithium-ion batteries last longer when kept between 20% and 80% charge, but since Eufy robots charge fully and then stop, keeping them docked is still the best practice.

Charge After Every Use

Even if the battery is still above 50%, it’s a good idea to recharge after each cleaning session. This prevents deep discharges, which can stress the battery over time.

Avoid Overcharging (Myth Busting)

Don’t worry—modern Eufy Robovacs are designed to stop charging once the battery reaches 100%. They won’t overcharge, even if left on the dock for days. In fact, it’s recommended to leave them docked when not in use.

Use Only the Original Charger

Using third-party docks or adapters can damage the battery or cause charging failures. Always use the charger that came with your Robovac. If you need a replacement, buy it directly from Eufy or an authorized retailer.

Step 6: Clean the Charging Contacts Regularly

Dust, hair, and debris can build up on the charging contacts, preventing a solid connection. Clean them every 2–4 weeks for reliable charging.

How to Clean the Robot’s Contacts

– Turn off the robot and flip it over
– Use a dry, soft cloth or cotton swab to gently wipe the metal contacts
– Avoid using water or cleaning solutions—moisture can cause corrosion

How to Clean the Dock’s Contacts

– Unplug the dock first
– Wipe the contacts with a dry cloth
– Use a can of compressed air to blow out any dust in hard-to-reach areas

Clean contacts ensure a strong electrical connection and faster charging.

Step 7: Monitor Battery Performance

Over time, all lithium-ion batteries degrade. Here’s how to tell if your Robovac’s battery is still healthy:

Check Runtime

A new Robovac should run for 60–100 minutes on a full charge, depending on the model. If you notice the runtime dropping significantly—say, from 90 minutes to 30 minutes—the battery may be aging.

Watch for Charging Issues

Signs of a failing battery include:
– Taking much longer to charge
– Not holding a charge
– Shutting off unexpectedly

Use the App for Diagnostics

If your model supports the Eufy Clean app, check the battery health section. Some models provide battery cycle counts or health percentages.

If the battery is no longer performing well, consider replacing it. Eufy sells replacement batteries for most models, and installation is usually straightforward (check your user manual for instructions).
