Incheon International Airport in South Korea has deployed six PUDU MT1 units in the arrival areas of T1 and T2 terminals for daily sweeping operations on large-area carpets. Faced with the operational characteristics of large public areas in the terminals, continuous passenger flow, and frequent cleaning tasks, the machines undertake high-frequency basic cleaning with wide-area cleaning, large capacity collection, and flexible operation modes. This helps the cleaning team maintain the cleanliness of the arrival areas while deploying personnel more flexibly to areas requiring detailed cleaning, such as VIP lounges and restrooms, thereby enhancing the collaborative efficiency and service stability of airport cleaning operations.
