• 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.
