Compared to traditional high-altitude cleaning methods (such as suspended platforms and manual cleaning), tethered roof cleaning drones offer three significant advantages: First, high safety, as operators do not need to climb to great heights, only needing to operate from the ground, greatly reducing the risk of falls; second, increased efficiency, with a single drone capable of cleaning 500-2000 square meters per day, 3-5 times that of manual labor; and third, controllable costs, especially suitable for cleaning irregular surfaces (such as curved glass and irregularly shaped structures), eliminating the need for scaffolding or renting large equipment, reducing overall costs by 40%-60%.
Currently, this technology is widely used in urban building maintenance, wind power operation and maintenance, and transportation facility cleaning. For example, after a wind power company adopted tethered drones to clean its turbine blades, the power generation efficiency of a single unit increased by 8%, and annual maintenance costs decreased by 200,000 yuan.
A tethered roof cleaning drone is a specialized unmanned aerial vehicle system specifically designed for cleaning the surfaces of high-altitude buildings and large facilities. Its core feature lies in its connection to a ground power supply or cleaning fluid supply system via a tethering device (usually a high-tensile-strength, lightweight composite cable), enabling long-term hovering and stable operation. This overcomes the limitations of traditional drones, such as short flight time and limited payload capacity, making it particularly suitable for cleaning and maintenance of high-altitude environments such as building facades, bridges, wind turbine blades, and large billboards.
