Connect the power adapter to the charging station and plug it into a wall outlet. The indicator light on the charging station will illuminate.
2. Initial Charging
Before first use, fully charge the robot vacuum cleaner. Place the robot onto the charging station, ensuring the charging contacts align. The robot's indicator lights will show the charging status. A full charge typically takes approximately 4-5 hours.

4. Remote Control Batteries
Open the battery compartment on the back of the remote control and insert the two AAA batteries, observing the correct polarity.
5. Virtual Wall Setup (Optional)
The virtual wall creates an invisible barrier that the robot will not cross. Insert two AA batteries into the virtual wall unit. Place it on the floor where you want to restrict the robot's access. Ensure the beam is not obstructed.
