The energy installmen tpasses the movement to brush discs in both sides through the transmission system and makes their separately clockwise and the anti-clockwise rotation. They sweep both sides trash together, and pass it to middle rolls brushes. Then, rolls brushes again sweep trash into the trashcan to realize the function of clear sweeping. This equipment is the medium and small sweeper, which can carry on the cleaning to each kind of trash. Both brushes can facilitate to sweep the wall corner and the near obstacle clearly. In this article, massive materials can be collected. One more ideal corridor sweeper design proposal has been determined by analysis and comparison of the different scavenging arrangement. Then the concrete structure design calculation can be made according to this plan. The structure of this equipment can be made more compacted. The strength of all parts are calculated, and they all guarantee the request of design. Because the parts of equipment can be made quite easily, and the production cost is quite low, it is one more ideal economical practical corridor sweeper.
