1. An air suction apparatus comprising:

  • an air suction port provided on a surface of the air suction apparatus; and

    an air suction controller that changes, according to a change in a dust concentration distribution in a periphery of the air suction port, an air suction mode, wherein the air suction mode is determined based on at least one of a shape, a size, a direction, an effective opening area, a position, or an air flow volume of the air suction port;

    a dust position determiner that determines a dust concentration region having a higher dust concentration than surroundings in the periphery of the air suction port;

    an air suction determiner that determines the air suction mode for applying a predetermined air suction flow to the determined dust concentration region;

    an air flow distribution determiner that determines an air flow distribution in a space where the air suction port performs air suction; and

    a dust generation determiner that determines a dust generation position, whereinthe air suction controller controls the air suction port based on the determined air suction mode, andthe dust position determiner estimates the dust concentration region based on the air flow distribution and the determined dust generation position.
