4.1 Special Notes Before Cleaning

• Before starting, clear the floor of scattered wires, hard objects, sharp items (such as nails, glass), and other debris. Also, remove items that are easily toppled, fragile, valuable, or could potentially cause danger. Avoid situations where the robot may become entangled, stuck, dragged, or cause harm to individuals or property.
• If using this product in an environment with drop-offs, it is essential to employ sturdy physical barriers to prevent the robot from accidentally falling and causing harm to individuals or property.
• During the initial cleaning process, it is advisable to accompany the robot throughout the entire session to assist with addressing any minor issues that may arise. Once resolved, the robot will be able to proceed with autonomous cleaning smoothly in subsequent sessions.
• If there are areas that do not require cleaning or where the robot may get stuck, you can set up virtual barriers using the mobile app to prevent the robot from entering those zones.
• Avoid letting the robot vacuum up hard or sharp objects (such as construction debris, glass, nails, etc.), as this may cause damage to both the robot and the floor surface.

4.2 Assembly
