The cleaning of the roof of the carriage has the following difficulties: 1. The overall length of the carriage is long, generally 120-160 meters, and the roof of the carriage is high. The worker usually needs to stand on a working ladder to clean, and can only clean a small range at a time and then move the working ladder, which is a frequent repetition of actions, and is laborious and tiring. 2. The most important and troublesome part of the cleaning of the roof of the carriage is the cleaning of the air outlet of the air conditioner. The air outlet of the air conditioner is usually designed to be about 2.26-2.35 meters from the ground. In order to meet the passenger carrying needs in different environments, subway operating companies design air outlets of different sizes and shapes, such as a herringbone shape and a fan shape. The angle of the air outlet is also of many types, such as obliquely downward, vertically downward and laterally. After each subway operation, a deep layer of dirt is formed on the air outlet. The ordinary cloth used by the worker in the cleaning work cannot penetrate into the interior of the air outlet, resulting in the remaining of dust and stains and affecting the air outlet quality of the air conditioner. 3. The worker needs to hold the cleaning tool close to the roof of the carriage for cleaning. The roof of the carriage has a lighting system, and the worker is affected by being too close to the light source, being too close to the dirt layer, looking up for a long time and holding the hand up for a long time, which causes a certain degree of strain on the worker's vision, respiratory system, spine and arm muscles.
