The robot must be used in accordance with the directions in this User Manual. Our company cannot be held liable or responsible for any damages or injuries caused by improper use. 2. Do not allow to be used as a toy. Close attention is necessary when used by or near children.x. Do not allow children to sit on the vacuum. 3. 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. 4. 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. 5. Only use as described in this manual. Only use attachments recom- mended or sold by the manufacturer. 6. Please make sure your power supply voltage matches the base station. 7. Do not handle or plug appliance with wet hands. 8. Non-rechargeable batteries are prohibited. 9. Do not use without dust bin and/or filters in place. 10. Do not operate the robot in an area where there are lit candles or fragile objects on the floor to be cleaned. 11. 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. 12. Keep hair, loose clothing, fingers, and all parts of body away from any openings and moving parts. 13. Do not operate the robot in a room where an infant or child is sleeping. 14. For INDOOR use ONLY. Do not use the robot in outdoor, commercial or industrial environments. Do not use Appliance on wet surfaces or surfaces with standing water. 15. Do not allow the robot to pick up large objects like stones, large pieces of paper or any item that may clog the robot. 16.

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. 18. 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. 19. Take care not to damage the power cord. Do not pull on or carry the robot or the base 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. 20. If the power cord is damaged, it must be replaced by the manufacturer or its service agent in order to avoid a hazard. For Household use only When using an electrical appliance, basic precautions should always be followed, including the following: 3 21. Do not use the base station if it is damaged. 22. Do not use the robot or the base 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. 23. Turn OFF the power switch before cleaning or maintaining the robot. Turn off all controls 24. The plug must be removed from the receptacle before cleaning or maintaining the base station. 25.

The battery must be removed and discarded according to local laws and regulations before disposal of the robot. 27. Please dispose of used batteries according to local laws and regula- tions. 28. Do not incinerate the robot even if it is severely damaged. The batteries can explode in a fire. 29. When not using the base station for a long period of time, please unplug it. 30. Prevent unintentional starting. Ensure the switch is in the off position before connecting to battery pack, picking up or carrying the appliance. Carrying the robot with your finger on the switch or energizing the robot that have the switch on invites accidents. 31. When battery pack is not in use, keep it away from other metal objects, like paper clips, coins,keys, nails, screws,ect, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire. 32. Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns. 33. Do not use a battery pack that is damaged or m…
