China is successfully replacing a 19th century industry with drones: skyscraper window cleaners

When we think of skyscrapers, the Western culture in which we have grown up makes us inevitably associate them with the United States and iconic skylines in cinema such as New York or Chicago, but the current reality is very different: China is the country that breaks the cord, according to the Council on Tall Buildings and Urban Habitatthe world’s leading authority on the classification of tall buildings: it is home to more than half of the world’s tallest skyscrapers. This architectural explosion has created an unprecedented maintenance challenge: having to clean millions of square meters of glass and metal facades. What started as a need for manpower has become a testing ground for advanced robotics and unmanned aviation thanks to a state plan called “Robot+” that automates tasks to compensate labor shortage. One of the most striking recent examples: automated cleaning from Nanchang Railway Station. Goodbye to human window cleaners. The traditional Spider-Man of buildings is disappearing and it makes perfect sense: the risk of accidents and the climatic conditions of cities like Shanghai or Guangzhou have made this profession increasingly less attractive for new generations, so cleaning companies it is difficult for them to find relief: the perfect scenario for automation. Furthermore, the data from cleaning drones is compelling: going from being able to clean 200 square meters a day to 10,000 with a cost between 10 and 20% less, according to the Wuhan startup Aero Technology collected by China Daily. Drones are best suited to difficult outdoors such as corners and nooks and work even on rainy or windy days without risk. And when finished, the drone uses its camera to capture images of the clean surface, which it transmits to ground personnel for review. If it doesn’t comply, give it a review. Why is it important. We have already glimpsed some of the advantages of automating cleaning at height, but one is truly essential: safety. According to the WHOfalls are the second global cause of death due to unintentional injuries, only behind traffic accidents, with about 684,000 deaths annually. In the specific workplace, they constitute one of the main risks in sectors such as construction or industry. especially dangerous are the falls in height. In the United States, OSHA data They return that falls represent between 35 and 39% of construction-related deaths. In Spain, falls from height represented in 2024 12.2% of all work-related deaths during work hours in all sectors and this year alone they cost the lives of 79 people in the Spanish state alone. The other big advantage is price: less labor, less operating time because they clean faster, lower equipment costs, and lower insurance premiums. Aero Technology quantifies savings between 10 and 20% compared to traditional methods, although the drone company Apex is more optimistic for your business, raising the range of savings up to 30 or 50% (although the reason is probably that you consider assemblies like scaffolding). Regarding water consumption, a study by Shanghai University of Engineering has shown which spends 21.8% less. Context. China faces the worst possible scenario in this framework: it is the country with the most skyscrapers in the world, it has a lot of air pollution that quickly dirtys its facades and it also suffers labor shortage for manual jobs. Although if we are looking for pioneers in the drone cleaning segment we have to go to the North American one. Surname born 2014, the Elevation from the Swiss Aerotain AG back in 2015 or the Norwegian KTV Working Dronethe owner and mistress of drone window cleaning is China. China had been preparing the ground for years, as demonstrated by different academic research papers on glass and facade cleaning robotsas this of cable-driven parallel robots from Tsinghua University or this other of fan-powered cleaning robots from the Harbin Institute of Technology. The Asian giant has the academic ecosystem, state financial support and an obvious need. Said and done: China was the one who democratized technology, moving from prototypes and more or less “artisanal” devices to large-scale production with scalable industrial systems and companies like DJI, UAEAV and Foxtech. Today they already produce between 80-90% of the world’s commercial drones and lead an industry that in 2024 was valued at 248 million dollars and has a projection of 1,257 million by 2033. according to Growth Market Reports. The substitutes. China has developed a complete industrial ecosystem that is essentially divided into two major technological aspects. On the one hand, high-pressure cleaning drones that are connected to water pumps that are on the ground, such as the DJI M400 or the solutions of Foxtech Robotics. On the other hand, autonomous climbing robots with sensors and AI navigation (such as robot vacuum cleaners) such as those from OneMovecapable of detecting and adapting to variations in façade surfaces. In between, variants in the form of projects with hybrid platforms such as that of Skybotics Technology Limited or wired parallel systems that offer high precision, such as this from the Faculty of Engineering of Shanghai University with three degrees of freedom. Some of the technologies that can be found in this type of robots are adaptive joints to reduce wind discomfort or “zero distance” spraying to increase pressure, both present in the DJI M400one of the most popular in the sector. Yes, but. Although facade cleaning robots are a revolution for the sector, they are not a panacea: they work best on flat surfaces, they have height restrictions (typically between 60 and 120 meters for wired systems) and although they have more margin than human labor to operate in worse weather conditions, they are not infallible. Finally, the initial cost is significant, which constitutes a barrier to entry for smaller companies because it is not only the drone, it is also extra auxiliary elements such as pumping stations, batteries, software or safety certifications. For example, only the complete Lucid Bots Sherpa kit It costs $75,000.which leads to opting for solutions such as renting or leasing. In any case, and … Read more
