With the acceleration of urbanization, cleaning and maintenance issues of high-altitude buildings, bridges, power facilities, etc. have become increasingly prominent. Traditional manual cleaning methods are not only inefficient and costly, but also pose safety risks in high-altitude operations. High-pressure water jet cleaning technology carried by drones has emerged as the times require, and with its unique advantages, it has become a new solution to this problem. This technology uses a high-pressure water jet device on a drone platform to achieve long-distance, high-altitude, and precise cleaning operations, with the advantages of high operating efficiency, low cost, and good safety.
