1. Important Safety Instructions
Please read this instruction manual carefully before using the product and keep it in a safe place for future reference. Failure to follow these warnings and instructions may result in electric shock, fire, or serious injury.
General Safety Precautions:
- The robot must be used in accordance with the directions in this user manual.
- 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; 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, you should operate the robot to ensure that it can detect the step necessary to place a physical barrier at the edge to keep the unit from falling. Make sure 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 make sure your power supply voltage matches the power voltage marked on the docking station.
- Do not handle or plug 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 where there are lit candles or fragile objects on the floor to be cleaned.
- Do not use and store in extremely hot or cold environments (below -5°C /23°F or above 40°C/104°F). Please charge the robot in temperature above 0°C/32°F and below 40°C/104°F. Follow all charging instructions and do not charge the battery pack or appliance outside of the temperature range specified in the instructions. Charging improperly or at temperatures outside of the specified range 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 robot on wet surfaces or surfaces with standing water.

- 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 the docking station by the power cord, use the power cord as a handle, close a door on the power cord, or pull power cord around sharp edges or corners. Do not run the robot over the power cord. Keep power cord away from hot surfaces. Do not unplug by pulling on cord. To unplug, grasp the plug, not the cord.
- If the power cord is damaged, it must be replaced by the manufacturer or its service agent in order to avoid a hazard.
- Do not use the docking station if it is damaged.
- Do not use the robot or the 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 in order to avoid a hazard.

3. Setup and Installation
Preparation Before Use:
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 the robot from getting entangled, stuck, dragged, or knocked down, which could cause damage to people or property.
If this product is used in a suspended environment (e.g., near stairs), be sure to use a sturdy physical barrier to prevent personal or property damage caused by the robot accidentally falling.
Remove Protective Film:
Remove the protective film from the robot and docking station before first use.
Install the Side Brushes:
Push the side brushes down firmly onto their posts until you hear a “click”. This indicates that they are securely in place.
Docking Station Installation:
- Connect the docking station to the adapter.
- Position 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 having reflective objects, such as floor mirrors, near the docking station to prevent signal reflection.
- Optional: To secure the docking station, attach the double-sided soft adhesive to the back or bottom of the charging dock and press it firmly against the wall or floor.
Initial Charging:
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 charging while powered off, it will automatically power on.
Water Tank Installation (for Mopping Function):
- Stick the mop cloth to the bottom of the water tank.
- Open the silicone seal plug of the water tank and fill the tank with clean water.
- 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.

5. Maintenance
Mop Cloth Removal and Maintenance:
- You can easily remove the water tank by pulling it upward from the rear of the water tank.
- Remove the top cover of the water tank.
- After cleaning or replacing the mop cloth, please refer to the "Water Tank Installation Instructions" to reinstall the water tank assembly, and then you can continue mopping.
Warm Tips:
- If you use disposable mop cloths, please directly discard them after use and replace with new ones.
- For washable mop cloths, please clean them in a timely manner after use or replace them according to the actual wear and tear.
- When the whole-house cleaning is completed or the mopping function is not needed temporarily, be sure to drain all the water in the water tank in a timely manner to prevent the remaining water inside the tank from continuously seeping out and causing water stains or puddles on the floor.
Friendly reminder: After finishing the mopping task, please thoroughly clean the mop immediately and dry it in a well-ventilated area. This is to avoid the mop from developing an odor or breeding bacteria due to long-term storage.
Dust Bin Maintenance:
Attention: The high-efficiency filter and filter cotton cannot be washed with water.
- Open the faceplate and take out the dust bin.
- Dumping of garbage.
- Remove the filter bracket, and then take out the high-efficiency filter and filter cotton.
- Clean the high-efficiency filter and filter cotton with a cleaning brush. Do not wash them with water.
- The main body of the dust box and the filter bracket can be washed with water. Rinse and allow to dry completely for at least 24 hours before returning to use.
