For different automobiles, the automobile top cleaning device mainly aims at private automobiles including sedan type automobiles, SUV type automobiles and the like, and particularly for SUV type automobiles, due to the fact that the automobile is tall and tall, the automobile top is a position which is difficult to be directly touched by a common person when the automobile is cleaned, and therefore difficulty is brought to the cleaning of the automobile top. In addition, in the course of modern people driving SUV off-road vehicles to test off-road traveling, large articles required for traveling, such as bicycles, surfboards, luggage boxes and the like, need to be placed on a luggage rack on the top of the off-road vehicle, so that the space in the off-road vehicle is fully utilized, and the space outside the off-road vehicle can be fully utilized to carry articles. Large articles placed on the luggage rack on the top of the off-road vehicle need to be stably connected with the vehicle body and can be conveniently taken by a user.

In the prior art, when a user takes a large article on a luggage rack on the roof of the off-road vehicle, the user needs to climb from the rear body of the off-road vehicle to a position close to the roof by means of an outer frame or a folding ladder. Or the user climbs to a position close to the roof through a folding ladder originally installed on the off-road vehicle roof or erected by self modification. With respect to the former, it is generally time consuming and laborious for a user to climb to a location near the roof of the off-road vehicle due to the large size of the vehicle body. In the latter case, the height, volume and load of the all terrain vehicle are increased by erecting a folding ladder on the top of the all terrain vehicle. Therefore, the folding ladder becomes an obstacle for certain limited-height terrain environments; and may easily snag on the roof and other items on the roof during travel of the off-road vehicle due to vibration jolts.
