Safety Information

Precautions

• This product is intended for floor cleaning in residential environments only. Do not use it outdoors (e.g., on an open porch), on non-floor surfaces (e.g., sofas), or in commercial or industrial settings.
• Clean or maintain the self-emptying charging station (hereinafter "station") and the robot only when the station is unplugged and the robot is switched off.
• Do not use the robot and station as toys, and do not step or stand on them. When the robot or station is in operation, supervise children and pets and keep them away as much as possible.
• Do not use this product in a room where infants or small children are sleeping.
• Do not allow children or persons with physical, mental, or sensory impairments to use or operate this product.
• If using in an elevated environment (e.g., a maisonette apartment), ensure a strong physical barrier is present to prevent injury or property damage from the robot accidentally falling.
• Do not place limbs or other body parts of people or pets into the rotating position of the robot's brush or into the machine's crevices to avoid injury.
• Before use, clear all scattered cables and other debris from the floor, and move objects that are easily knocked over, fragile, valuable, or potentially dangerous to prevent the robot from tangling, jamming, dragging, or knocking them over, which could lead to injury or property damage.
• Ensure the floor where the robot operates has no standing water, otherwise the robot could be water-damaged.
• Do not use it to clean burning objects (e.g., unextinguished cigarettes, matches, ash, etc.) or flammable and explosive items (e.g., lighters, gasoline, toner and powder for printers or copiers, etc.).
• Before use, ensure that components such as the dustbin, filters, dust bag, side brush, mop, main brush, and main brush cover are correctly installed.
• Do not use the product without a dust bag.
• Beware of heat from hot water. Do not touch the water outlet of the station.
• Do not pour liquid agents onto the robot and station.
• Do not use it to clean long-pile carpets (some dark-colored carpets may not be cleaned properly).
• If the product is damaged in any way, do not use it and contact official customer service promptly for a solution.
• Do not store or use it in an environment with a temperature above 40°C, below 0°C, or where the floor is liquid or viscous.
• Do not use disinfectants other than the official cleaning fluid, otherwise the robot and station could be severely damaged.
