The maintenance guide on the official website recommends checking whether the cleaner’s nozzles are blocked, whether the spray angle and water flow are normal, and observing the operation of the brushes and drive rollers. The fan filter pressure differential, flexible air duct connections, valves, and water piping should also be included in the inspection. Before cleaning the water tank, shut off the water supply and confirm that the heater temperature has dropped. Then drain the tank and clean the inner walls and filter screen. Afterward, refill the tank with fresh water and check the water level and condition. Specific maintenance arrangements should be carried out in accordance with the equipment instructions and on-site safety requirements.
