When using an electrical appliance, basic precautions should always be followed:
- The robot must be used in accordance with the directions in this user manual. The company cannot be held liable or responsible for any damages or injuries caused by improper use.
- Do not allow to be used as a toy. Close attention is necessary when used by or near children. Do not allow children to sit on the vacuum.
- Clear the area to be cleaned. Remove power cords and small objects from the floor that could entangle the Robot. Tuck rug fringe under the rug base, and lift items such as curtains and table cloths off the floor.
- If there is a drop-off in the cleaning area due to a step or stairs, operate the robot to ensure it can detect the step and place a physical barrier at the edge to prevent falling. Ensure the physical barrier is not a trip hazard.
- Only use as described in this manual. Only use attachments recommended or sold by the manufacturer.
- Please ensure your power supply voltage matches the power voltage marked on the docking station.
- Do not handle or plug the appliance with wet hands.
- Non-rechargeable batteries are prohibited.
- Do not use without dust bin and/or filters in place.
- Do not operate the robot in an area with lit candles or fragile objects on the floor.
- Do not use or store in extremely hot or cold environments (below -5°C /23°F or above 40°C/104°F). Charge the robot in temperatures above 0°C/32°F and below 40°C/104°F. Follow all charging instructions; do not charge the battery pack or appliance outside the specified temperature range, as this may damage the battery and increase the risk of fire.
- Keep hair, loose clothing, fingers, and all parts of body away from any openings and moving parts.
- Do not operate the robot in a room where an infant or child is sleeping.
- For INDOOR use ONLY. Do not use the robot in outdoor, commercial, or industrial environments. Do not use the robot on wet surfaces or surfaces with standing water.
- Do not allow the robot to pick up large objects like stones, large pieces of paper, or any item that may clog the robot.
- Do not use the robot to pick up flammable or combustible materials such as gasoline, printer or copier toner, or use in areas where they may be present.
- Do not use the robot to pick up anything that is burning or smoking, such as cigarettes, matches, hot ashes, or anything that could cause a fire.
- Do not put any object into openings. Do not use with any opening blocked; keep free of dust, lint, hair, and anything that may reduce air flow.
- Take care not to damage the power cord. Do not pull on or carry the robot or docking station by the power cord, use it as a handle, close a door on it, or pull it around sharp edges or corners. Do not run the robot over the power cord. Keep the power cord away from hot surfaces. Do not unplug by pulling on the cord; grasp the plug.
- If the power cord is damaged, it must be replaced by the manufacturer or its service agent to avoid a hazard.
- Do not use the docking station if it is damaged.
- Do not use the robot or docking station if it is not working properly, has been dropped, damaged, left outdoors, or come in contact with water. It must be repaired by the manufacturer or its service agent to avoid a hazard.
- Turn off the power switch before cleaning or maintaining the robot. Turn off all controls.
- The plug must be removed from the receptacle before cleaning or maintaining the docking station.
- Remove the robot from the docking station and turn off the power switch before removing the battery for disposal.
- The battery must be removed and discarded according to local laws and regulations before disposal of the robot.
- Please dispose of used batteries according to local laws and regulations.
- Do not incinerate the robot even if severely damaged, as batteries can explode in a fire.
- When not using the docking station for a long period, please unplug it.
- Prevent unintentional starting. Ensure the switch is in the off position before connecting the battery pack, picking up, or carrying the robot. Carrying the robot with a finger on the switch or energizing the robot with the switch on invites accidents.
- When the battery pack is not in use, keep it away from other metal objects like paper clips, coins, keys, nails, screws, etc., that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
- Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, seek medical help. Liquid ejected from the battery may cause irritation or burns.
- Do not use a battery pack that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behavior resulting in fire, explosion, or risk of injury.

Product Installation
B1 Special Note
Diagram 1: Shows a floor with scattered wires, objects, and debris on the left (marked with a cross ❌), and a cleared floor on the right (marked with a checkmark ✔️). Before starting, please 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.
Diagram 2: Shows a floor with a drop-off (e.g., stairs) on the left (marked with a cross ❌), and a floor with a physical barrier placed at the edge on the right (marked with a checkmark ✔️). 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.
Tips:
- 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.
B2 Assemble
- Remove the protective film on the robot and the charging station. (Diagram shows robot and station with films indicated for removal).
- Install the side brush. (Diagram shows side brush being attached to the robot with a 'Click' indicator).
- Place the charging station and connect the power supply. Place the charging station on a flat surface and plug in the power cable. Ensure there are no objects within 0.5 meters on either side and 1.5 meters in front of the charging station to prevent obstruction of the signal. Avoid placing reflective objects, such as floor mirrors, around the charging station to prevent signal reflection. (Diagram shows charging station placement with clearance indicators).
- Charging. Align the Charging electrode at the back of the robot with the charging pins on the charging station, and place the robot accordingly. When the button light starts flashing, it indicates that the robot is placed correctly. (Diagram shows robot on charging station). Charging time is approximately 6.5 hours. Battery level <50%: Purple breathing light. Battery level >50%: Blue breathing light. When the robot is charging under powered off status, it will automatically turn on during the charging process.
