Cleaning apparatus and cleaning method

A cleaning apparatus, comprising two wiping parts opposite to each other, a connection part and a cleanliness detection device, the two wiping parts defining a space therebetween to accommodate a part to be cleaned, and the two wiping parts being connected through the connection part,

• wherein the cleanliness detection device is configured to detect cleanliness of the part to be cleaned;
• and
• the connection part is configured to control a distance between the two wiping parts based on the detected cleanliness,
• wherein a wiping part of the two wiping pails is of a plate shape, and the cleaning apparatus further comprises a driving par configured to control the wiping part to move in a plane where the wiping part is located, and
• wherein a pressure sensor is provided on the wiping part as the cleanliness detection device, connected with the driving part, and configured to sense a pressure in a wiping process;
• in a case where the pressure for a position of the part to be cleaned sensed by the pressure sensor is larger than a predetermined threshold value, the driving part is configured to control the wiping part to wipe the sensed position;
• and
• in a case where the pressure for a position of the part to be cleaned sensed by the pressure sensor is smaller than or equal to the predetermined threshold value, the driving part is configured to control the wiping parts to move away from each other.
