Important Safety Instructions

WARNING: Read all safety warnings and instructions. Failure to follow the warnings and instructions may result in electric shock, fire or serious injury.

READ ALL INSTRUCTIONS BEFORE USING THIS APPLIANCE.

For Household use only

When using an electrical appliance, basic precautions should always be followed, including the following:

1. The robot must be used in accordance with the directions in this User Manual. Lefant 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. 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, operate the Robot to ensure it can detect the step. 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 recommended or sold by the manufacturer.
6. Please ensure your power supply voltage matches the power voltage marked on the Docking Station.
7. Do not handle or plug the appliance with wet hands.
8. Non-rechargeable batteries are prohibited.
9. Do not use without the dust bin and/or filters in place.
10. Do not operate the robot in an area with lit candles or fragile objects on the floor.
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 temperatures 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 the specified temperature range. Charging improperly or at temperatures outside 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 the 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 flammable or combustible materials such as gasoline, printer or copier toner, or use in areas where they may be present.
17. 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 Docking Station by the power cord, use the power cord as a handle, close a door on the power cord, or pull the power cord 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; 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 to avoid a hazard.
21. Do not use the Docking Station if it is damaged.
22. 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 to avoid a hazard.
23. Turn OFF the power switch before cleaning or maintaining the robot. Turn off all controls.

28. Do not incinerate the robot even if it is severely damaged. The batteries can explode in a fire.
29. When not using the Docking 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 the battery pack, picking up, or carrying the appliance. Carrying the robot with your finger on the switch or energizing the robot with the switch on invites accidents.
31. 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.

33. 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.
34. Do not expose a battery pack or appliance to fire or excessive temperature. Exposure to fire or temperature above 130°C/265°F may cause explosion.
35. Have servicing performed by a qualified repair person using only identical replacement parts.
36. Do not modify or attempt to repair the robot or the battery pack (as applicable) except as indicated in the instructions.
37. Do not operate the robot in a room that has lit candles on furniture that the vacuum may accidentally hit or bump into.
38. Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
