Do not use the batteries, chargers and dust collection charging piles of any third party. Do not disassemble, repair or refit the battery and dust collection charging pile without permission. Do not place the dust collection charging pile close to heat sources (such as radiator). Do not wipe or clean the dome of the dust collection charging pile with a damp cloth or wet hands. Do not discard used batteries at will. Before discarding the sweeping and mopping robot, the power supply must be disconnected and the batteries should be taken out of the sweeping and mopping robot for environmental protection. In order to avoid danger, any damaged power cord must be replaced by professionals from the manu- facturer, its maintenance department or similar departments. If you need to transport the product, make sure that the machine is turned off and it is recommended to use the original package. Do not pour water into the device or immerse it in water. If it will be not used for a long time, fully charge the machine, turn it off and put in a cool and dry place. Charge the machineat least once every three months to avoid battery damage due to over discharge. This appliance contains batteries that are only replaceable by skilled persons. This appliance can be used by children aged from � years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved.
