Do not use it outdoors (e.g., open balconies), on non-floor surfaces (e.g., sofas), or in commercial/industrial environments. • Clean or maintain the charging dock and the robot only when the charging dock is powered off and the robot is turned off. • Do not treat the robot or charging dock as a toy, nor ride on or stand on them. When the robot or charging dock is in operation, supervise children and pets to keep them at a safe distance. • Do not use this product in rooms where infants or young children are sleeping. • Do not allow children, or people with physical, mental, or sensory impairments, to use or operate this product. • When using the product in elevated environments (e.g., duplex floors), be sure to use a stable physical barrier to prevent the robot from accidental falling and causing personal injury or property damage. • Do not let human or pet body parts (such as limbs) get close to the rotating brush head of the robot or put them into the gaps of the machine to avoid injury. • Before use, clean up scattered wires and other debris on the floor, and move unstable, fragile, valuable, and potentially hazardous items to prevent them from being tangled, stuck, dragged, or knocked over by the robot (which may cause personal injury or property damage). • Ensure the floor where the robot operates is free of standing water; otherwise, the robot may be damaged by water ingress. • Do not use the robot to clean any burning objects (e.g., unextinguished cigarette butts, matches, ashes) or any flammable and explosive items (e.g., lighters, gasoline, toner and color powder used in printers or copiers). • Before use, ensure that components such as the dustbin, filter, side brush, and mopping pad are properly installed. • Do not spray or douse the robot and charging dock with any liquid. • Do not use the robot to clean long-pile carpets (note: some dark-colored carpets may not be cleaned properly). • If the product is damaged in any way, do not use it and contact the official after-sales service promptly for resolution. • Do not store or use the product in environments where the temperature is above 40, below 0, or where the floor has any liquid or viscous substances. • Do not place any objects on the robot or charging dock, and do not cover them with any items (including dust covers). • Avoid having hard or sharp objects (e.g., construction waste, glass, iron nails) on the floor where the robot operates; otherwise, the robot and the floor may be scratched. 3 • Be sure to place the charging dock on a horizontal, hard indoor floor. Keep the robot, charging dock, and power cord away from open flames, heat sources (e.g., radiators), and areas that are damp, have water, are narrow, or may cause the robot to be elevated. • Put away fragile items and debris (e.g., vases, mirrors, plastic bags) placed on the floor to prevent the robot from being blocked during operation or causing damage to valuable items at home when it touches them slightly. • Do not place low-lying objects such as floor mats and shoes at locations where the robot may fall (e.g., stair entrances); otherwise, it may interfere with the normal operation of the robot's anti-fall sensor and cause the robot to fall. • Use this product in accordance with the instructions in the manual. The user shall bear full responsibility for any loss or injury caused by improper use, or any indirect loss resulting from the use, misuse, or inability to use this product. SAVE THESE INSTRUCTIONS For indoor use only Direct current Alternating current To satisfy RF exposure requirements, a separation distance of 20 cm or more should be maintained between this device and persons during device operation. To ensure compliance, operations at closer than this distance is not recommended. The antenna used for this transmitter must not be co-located in conjunction with any other antenna or transmitter. 4 This marking indicates that this product should not be disposed of with other household waste throughout the EU. To prevent possible harm to the environment or huma…
