3. Setup

Base Station Installation

Place the base station on a flat surface and connect the power cord. Ensure there are no objects within 0.5 meters on both sides and 1.5 meters in front of the charging station to prevent signal blockage. Avoid reflective objects like floor mirrors around the charging station.

Robot Assembly

1. Align and install the mop mounting shaft and the side brush onto the robot. You will hear a "click" sound when correctly installed.
2. Remove the protective film from the robot.

Water Tank and Cleaning Solution

1. Watering the Clean Water Tank: Lift the clean water tank, open the upper cover, add clean water, then tightly close the cover and install the tank back into the base station. Do not pour hot water or cleaning solution directly into this tank.
2. Adding Cleaning Solution: Remove the clean water tank, open the sealing plug of the cleaning solution box, and pour the cleaning solution into it. Close the plug and install the water tank back. Attention: Do not add non-official cleaning solutions or disinfectants. This step can be skipped if not using floor cleaning solution daily.

Power On and Initial Charge

Press and hold the power button for 3 seconds to turn on the device. Once the power indicator light is constantly on and you hear a voice prompt, place the robot in front of the base station. Ensure the base station is powered on. Press the power button twice briefly, and the robot will automatically return to the base station for charging. Keep the robot charged for daily use.

• During charging, the purple light breathes if the battery is less than 50%, and the blue light breathes if greater than 50%.
• If the robot is charged while off, it will automatically turn on.
• If the battery is low, you may need to place the robot directly into the base station for charging.

App Connection

Start Cleaning

Briefly press the power button to start cleaning. The robot will dynamically plan the cleaning route, typically mapping along walls and then cleaning in a zigzag pattern. It is recommended to let the robot start from the charging state and not move the base station during cleaning.

Pause

Briefly press the power button once to pause. Press it twice to send the robot back to the charging dock. In paused state, press once to resume cleaning. Alternatively, place the robot back into the base station to terminate cleaning.

Auto-sleep Mode

If unoperated for more than 5 minutes, the robot enters dormant state. Press any key to wake it up. If battery is below 70%, it shuts down after 24 hours of standby. If below 30%, it shuts down 10 minutes after dormancy.

Do Not Disturb Mode

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

Charging

After cleaning, the robot automatically returns to the base station. Press the power button twice briefly to send it back. The button indicator light will flash in a breathing pattern 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 back on the base station.

Dust Collection

After cleaning, the robot returns to the base station and 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 dustbin cover and disposable dust bag are properly installed.

Air Dry

After completing the cleaning task, the robot returns to the base station to clean the mop and then air-dry it automatically.

Clean the Mop

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