Since the 70 s in the 20 th century, industries such as petroleum, chemical, natural gas and nuclear industries have rapidly developed, and various pipelines have been widely used as an important material conveying facility. They are often erected in the air or underground to form intricate networks of pipes. The space of pipeline, road conditions, light to and operational environment's restriction, people are difficult directly to intervene, make artifical maintenance not only difficult, and are with high costs moreover. The pipeline robot takes place by taking turns from this, and fine help people have solved above-mentioned problem.

Pipeline transportation is widely applied to various aspects of nuclear industry, petroleum and coal and social life as an efficient fluid transportation means. However, the closed characteristic of the pipeline causes troublesome work such as detection, flaw detection, maintenance, desilting and the like. The internal environments of pipelines such as petroleum and natural gas conveying pipelines, urban water conveying pipelines, factory sewage pipelines and the like which need to be cleaned frequently have large differences, the required cleaning modes are different, and the smooth operation of the pipeline cleaning work needs to be further aggravated.

Relatively strict central air conditioner use and cleaning rules are successively issued by foreign health institutions. At present, the air pipe cleaning association of the central air conditioner is established in developed countries, such as: the international society for ventilation and health, the american society for cleaning air ducts, the european association for cleaning air ducts, etc., the cleaning of air ducts of foreign central air conditioners has formed a huge industry. At present, only a few domestic central air-conditioning cleaning companies exist, and the clear equipment of the domestic central air-conditioning cleaning companies mainly depends on import, so that the equipment cost is high. Although the importance of central air conditioning duct cleaning is becoming increasingly appreciated, the high cost of cleaning is prohibitive.
