Let’s dive in!

What You’ll Need to Charge Your Eufy S1 Pro

Before you begin, make sure you have the following items ready:

• The Eufy S1 Pro robot vacuum
• The official Eufy charging dock (included in the box)
• The power adapter that came with your S1 Pro
• A flat, stable surface near a power outlet
• At least 1.5 feet (about 45 cm) of clear space around the dock
• Access to the EufyHome app (optional but recommended)

Using only the original charging equipment is crucial. The Eufy S1 Pro is designed to work specifically with its included dock and adapter. Third-party chargers or docks may not deliver the correct voltage or current, which can damage the battery or reduce performance over time.

Step 1: Unbox and Inspect Your Eufy S1 Pro

When you first unbox your Eufy S1 Pro, take a moment to inspect all components. You should find:

• The robot vacuum
• The self-emptying charging dock
• Power adapter
• Side brushes (pre-installed or in a small bag)
• Cleaning tool
• User manual and quick start guide

Check that the charging contacts on both the robot and the dock are clean and free of debris. These small metal strips are essential for transferring power. If you notice any dust or residue, gently wipe them with a dry, lint-free cloth.

Also, ensure the robot’s battery isn’t completely drained. If the unit was stored for a long time, it may arrive with a low charge. That’s normal—just proceed to charging.

Step 2: Choose the Right Location for the Charging Dock

The placement of your charging dock is one of the most important steps in setting up your Eufy S1 Pro. A poorly positioned dock can lead to failed docking, interrupted charging, or even navigation errors.

Follow these guidelines when choosing a spot:

Select a Flat, Stable Surface

Place the dock on a hard, level floor—such as tile, hardwood, or laminate. Avoid placing it on thick carpet or rugs, as the robot may struggle to dock properly. The surface should be dry and free of clutter.

Ensure Clearance on All Sides

The Eufy S1 Pro needs space to approach and dock smoothly. Leave at least 1.5 feet (45 cm) of open space in front of and on both sides of the dock. This allows the robot to align itself correctly using its sensors.

Avoid High-Traffic Areas

While it’s convenient to place the dock in a central location, avoid doorways, hallways, or areas where people or pets frequently walk. This reduces the chance of accidental bumps or interference.

Keep It Away from Obstacles

Don’t place the dock near furniture legs, power cords, or low-hanging objects. The robot uses laser navigation (LDS) to map your home, and obstacles can confuse its pathfinding.

Near a Power Outlet

The dock must be plugged into a working wall outlet. Use the included power adapter—do not use extension cords or power strips unless absolutely necessary. If you must use one, ensure it’s a high-quality, surge-protected model.

Ideal Locations Include:

• A corner of the living room
• Along a wall in a hallway (with clearance)
• Inside a dedicated cleaning closet or nook

Once you’ve chosen the perfect spot, place the dock firmly on the floor and plug it in. You should see a solid white or blue light on the dock, indicating it’s powered and ready.

Step 3: Power On the Eufy S1 Pro

Before charging, make sure your robot is turned on. Here’s how:

Locate the Power Button

On the top of the Eufy S1 Pro, you’ll find a circular power button with a light ring around it. Press and hold it for 3 seconds until the light turns on.

Check the Status Light

The light ring will display different colors to indicate the robot’s status:

• Solid white: Robot is on and ready
• Blinking white: Robot is charging
• Solid red: Low battery or error
• Blinking red: Charging error or dock not detected

If the light is red or blinking, don’t panic—this could just mean the battery is low. Proceed to charging.

Step 4: Manually Dock the Robot for the First Charge

For the first charge, it’s best to manually place the robot on the dock to ensure a proper connection.

Align the Robot with the Dock

Pick up the Eufy S1 Pro and carefully place it on the charging dock. Make sure the charging pins on the bottom of the robot align with the metal contacts on the dock. The robot should face forward, with its sensors aligned toward the dock’s front.

Listen for a Confirmation Sound

When properly docked, the robot will emit a soft beep or chime, and the light ring will turn solid white or begin blinking white. This indicates charging has started.

Check the Eufy App (Optional)

If you’ve downloaded the EufyHome app and connected your robot to Wi-Fi, open the app to confirm charging status. You’ll see the battery percentage and a “Charging” indicator.

Let It Charge Fully

The Eufy S1 Pro typically takes 3 to 4 hours to charge from 0% to 100%. Avoid interrupting the charge during this time. Once fully charged, the light will turn solid white, and the robot will be ready for use.

Step 5: Enable Auto-Docking for Future Charges

After the first full charge, your Eufy S1 Pro will automatically return to the dock when the battery is low or when a cleaning cycle is complete.

How Auto-Docking Works

The robot uses its built-in sensors and mapping technology to navigate back to the dock. It will do this:

• When the battery drops below 20%
• After finishing a scheduled cleaning
• When you press the “Home” button in the app

Ensure the Dock Is Powered and Visible

For auto-docking to work, the dock must remain plugged in and unobstructed. If the robot can’t “see” the dock due to obstacles or poor placement, it may get stuck or fail to charge.

Use the Eufy App to Monitor Docking

The app will notify you when the robot docks successfully. You can also check its location and battery level in real time.

Step 6: Maintain Proper Charging Habits

To keep your Eufy S1 Pro in top condition, follow these best practices:

Charge After Every Use

Even if the battery isn’t fully drained, it’s a good idea to return the robot to the dock after each cleaning. Lithium-ion batteries perform best when kept between 20% and 80% charge. Avoid letting the battery drop to 0% regularly.

Don’t Leave It Off the Dock for Long Periods

If you won’t be using the robot for several days, store it on the dock. This keeps the battery topped up and prevents deep discharge, which can shorten battery life.

Avoid Extreme Temperatures

Don’t charge the robot in very hot or cold environments. Ideal charging temperature is between 50°F and 95°F (10°C to 35°C). Avoid placing the dock near heaters, radiators, or in direct sunlight.

Clean the Charging Contacts Monthly

Over time, dust, hair, and debris can accumulate on the charging pins. This can prevent a solid connection and slow down charging.

To clean:

• Turn off the robot and unplug the dock
• Use a dry cotton swab or microfiber cloth to gently wipe the metal contacts on both the robot and dock
• Do not use water or cleaning solutions
• Let the contacts dry completely before reconnecting

Check for Firmware Updates

Eufy regularly releases firmware updates that can improve battery management and charging efficiency. Use the EufyHome app to check for updates and install them when available.

Troubleshooting Common Charging Issues

Even with proper care, you might encounter charging problems. Here’s how to fix the most common issues:
