Abstract
The light transmittance of greenhouse surface directly affects the illumination of greenhouse, and will eventually affect the indoor ground temperature, temperature, humidity and Photosynthesis of crops, thus affecting the growth of crops. As a modern greenhouse maintenance and cleaning equipment, greenhouse cleaning machine plays an active role in improving the light transmittance of greenhouse and improving the production efficiency of farmers. This paper mainly expounds the structure, principle and method of different kinds of greenhouse cleaning machines in China and abroad, analyzes the current development situation and prospects of greenhouse cleaning equipment, and puts forward some suggestions.
Highlights
Greenhouse cultivation, as a new direction of modern agriculture development, has gradually changed the traditional planting mode
The best growth environment can be provided,but as time goes on, more dust will be deposited on the greenhouse surface, and algae will even grow, which will have a greater impact on the light transmittance in the greenhouse[5,6].In order to reduce the cost of greenhouse investment, many farmers choose to clean the greenhouse by themselves

Summary
Greenhouse cultivation, as a new direction of modern agriculture development, has gradually changed the traditional planting mode. It plays an irreplaceable role in increasing crop yield, improving quality and easing off-season vegetable supply in China [1,2,3,4]. The research and development of cleaning equipment with high scientific and technological content, with advanced automatic control technology, natural products manufacturing costs on the high side[7]; while most of the existing greenhouses in China are arch greenhouses and sunlight greenhouses, which the economic benefit and scientific and technological content of the existing greenhouses still lag behind,compared with the modern large-scale greenhouses in developed countries.the cost of greenhouse cleaner developed in China is not easy to be high, otherwise it is difficult for farmers to accept it
