Compared with the traditional collection mode, the system has the following advantages:

1) the labor intensity of garbage collection is obviously reduced, the collection efficiency is improved, the human resources are reduced, and the human cleaning cost is greatly reduced;

2) the garbage flow is sealed and hidden and is completely isolated from the people flow, so that the probability of disease transmission is greatly reduced;

3) the smell sense and the visual pollution to residents are avoided, and the sanitary environment such as a canteen is improved;

4) the traditional pigwash cleaning cost is reduced, the collection and treatment of slag and oil are realized, and the profit and subsidy are brought to the canteen;

5) obviously improves the grade and the environment-friendly image of the building, and recycles garbage with recycling value to the maximum extent.
