• Do not allow children or pets to play with or operate the robot/base station. Supervise them closely when the device is in operation.
• Do not use in rooms where infants or young children are sleeping.
• If used in a suspended environment (e.g., duplex floor), ensure a sturdy physical barrier is in place to prevent falls.
• Keep limbs and other body parts away from rotating brushes and machine gaps to prevent injury.
• Before use, clear scattered wires, fragile items, and other obstructions from the floor to prevent entanglement, damage, or personal injury.

2. Physical Barrier (Suspended Environments): If using in a suspended environment (e.g., duplex floor), ensure a firm physical barrier is in place to prevent falls.
3. Floor Condition: Ensure there is no accumulated water on the floor. Do not wash the main unit with water.
4. Install Mop and Side Brush: Align and install the mop mounting shaft and the side brush onto the robot. A "click" sound confirms correct installation.
5. Remove Protective Film: Remove any protective film from the robot.

3.2 Base Station Installation

Place the base station on a flat surface and connect it to a power socket. Ensure no objects are within 0.5 meters (1.64 ft) on both sides and 1.5 meters (4.92 ft) in front of the charging station to prevent signal blockage. Avoid placing reflective objects (e.g., floor mirrors) around the station.

3.3 Watering the Clean Water Tank

Lift the clean water tank upward, open its upper cover, and add clean water. Tightly close the cover and install the tank back into the base station. Ensure it is fully installed.

• Do not pour hot water into the tank, as it may cause deformation.
• Do not add cleaning solution directly to the tank, as it may lead to excessive concentration.

3.4 Adding Cleaning Solution

Remove the clean water tank, open the sealing plug of the cleaning solution box, and pour the cleaning solution into the box. Close the plug and reinstall the water tank.

• Only use official cleaning solutions or disinfectants to avoid product damage.
• This step can be skipped if you do not need to use cleaning solution for daily use.

3.5 Power On and Charge

Press and hold the power button for 3 seconds to turn on the device. Once the power indicator light is steady, place the robot in front of the powered-on base station. Double-click the power button, and the robot will automatically return to the base station for charging. Keep the robot charged for daily use to maintain battery performance.

• If the robot is charged while turned off, it will automatically turn on.
• If the battery is too low, place the robot directly into the base station for charging.

3.6 Connect to the App

1. Download the App: Search for "Lefant" in your app store (iOS/Android) or scan the QR code provided in the manual.
2. Enter Network Configuration Mode: Press and hold the robot's power button for 6 seconds until you hear a voice prompt "Entering network configuration mode." The power indicator light will flash slowly in blue.
3. Add Device: Open the Lefant app, click "Add Device" or the "+" button, and follow the on-screen prompts to add your device.

Note: Ensure your phone and home network are connected before configuring. If the robot remains in the waiting-to-connect state for more than 3 minutes, the WiFi function will turn off. Re-enter network configuration mode to connect again.

4. Operating Instructions

4.1 Power On/Off

• Power On: Press and hold the power button for 3 seconds. The indicator light will turn on, and the robot will enter standby.
• Power Off: Press and hold the power button for 12 seconds. Note: The robot cannot be powered off while charging.

4.2 Start Cleaning

Briefly press the power button to start cleaning. The robot will dynamically plan its cleaning route, typically starting with mapping along walls and then cleaning rooms in a zigzag pattern.

• It is recommended to let the robot start automatically from the charging state to ensure smooth return to the base station.
• Do not move the base station during cleaning.
• If the battery is low, charge it before cleaning.
• Clear all wires and valuable items from the floor before cleaning.
• If cleaning time is less than 5 minutes, a new map will not be created or overwrite the old one.
• If the battery level is insufficient during cleaning, the robot will return to the base station. After reaching 80% charge, it will resume cleaning from the interruption point.
• When cleaning, the mop will rise by default for carpets. Adjust carpet avoidance settings in the app if needed.
• Select pure sweeping or sweeping and mopping mode via the app before each task.

4.3 Pause

Press the power button once to pause. Press twice to send the robot back to the charging dock. Press once again to resume cleaning. Alternatively, manually place the robot back on the base station to terminate the task.

4.4 Auto-sleep Mode

If inactive for more than 5 minutes, the robot enters dormant state. Wake it up by pressing any key. If battery is below 70%, it shuts down after 24 hours. If below 30%, it shuts down after 10 minutes.

4.5 Do Not Disturb Mode

The default do-not-disturb period is 22:00 to 08:00. This can be modified or turned off in the mobile app (Settings > Do Not Disturb). You can also set whether the robot initiates cleaning, resumes cleaning, performs dust collection, washes/dries the mop, or controls voice broadcast/indicator lights during this period.

4.6 Charging

After cleaning, the robot automatically returns to the base station. Double-click the power button to send it back. The button indicator light will flash while charging and turn off when fully charged.

• If the robot cannot find the base station, it returns to the starting position. Manually place it on the base station.

4.7 Dust Collection

After cleaning, the robot automatically detects if dust collection is needed. You can also manually start/pause dust collection via the app.

• Do not manually initiate dust collection multiple times in quick succession.
• Ensure the dustbin cover and disposable dust bag are properly installed.

4.8 Air Dry

After cleaning, the robot returns to the base station to clean the mop, then automatically air-dries it.

4.9 Clean the Mop

When starting a sweeping and mopping task, the robot first cleans the mop. The mop washing interval can be set in the app. After washing, the robot returns to the relay point to continue cleaning. You can manually control mop washing via the app. The mop-washing process can be stopped in the device settings.

• To ensure proper mop cleaning, let the robot start automatically from the charging state.
• Do not move the base station during cleaning.
