3. Setup and Installation

3.1 Pre-Installation Notes

Before starting, please clear the floor of scattered wires, hard objects, sharp items (such as nails and glass) and other debris. Also, remove items that are prone to falling, fragile, valuable or potentially hazardous. This prevents entanglement, getting stuck, or damage to the robot, people, or property.

If the robot is used in an elevated area, ensure a sturdy physical barrier is in place to prevent accidental falls.

Tips:

• During initial cleaning, it is advisable to monitor the robot to address any minor issues. Once resolved, the robot can operate autonomously.
• Avoid vacuuming hard or sharp objects (e.g., construction debris, glass, nails) as this may damage the robot and floor.

3.2 Remove Protective Film

Remove all protective film from the robot and the docking station before use.

3.3 Install the Side Brushes

Push the side brushes down firmly onto their posts until you hear a “click”, indicating they are securely in place.

3.4 Docking Station Installation

1. Connect the docking station to the power adapter.
2. Place the docking station against a wall on a flat surface. Ensure there are no items within 0.5m (1.64 ft) to the left or right and 1.5m (4.92 ft) in front to avoid blocking the charging signal. Avoid reflective objects, such as floor mirrors, near the docking station to prevent signal reflection.
3. Secure the charging dock: After positioning, attach the double-sided soft adhesive to the back or bottom of the charging dock to secure it to the wall or floor.

3.5 Charging the Robot

Place the robot with its button side facing the docking station. When the button light starts to blink, it indicates correct placement. If the robot is powered off while charging, it will automatically power on.

3.6 Water Tank Installation

1. Stick the mop cloth to the bottom of the water tank.
2. Open the silicone seal plug of the water tank and fill the tank with clean water.
3. Close the seal plug.
4. Align the fixing posts of the water tank with the installation holes on the bracket, then press vertically downwards until the water tank is fully attached to the bottom of the robot. Once this is done, the installation is complete, and you can use the mopping function normally.
