Abstract
A partition skirt device for a cleaning apparatus includes an inner ring and a skirt body. The skirt body includes: a root connected to the inner ring; an edge part arranged at an end of the skirt body away from the inner ring; and a plurality of collapsing parts arranged at intervals between the root and the edge part along a circumferential direction of the skirt body, and each extending along a radial direction of the skirt body. Along a thickness direction of the skirt body, the collapsing part protrudes relative to the skirt body on a first side surface of the skirt body and is recessed relative to the skirt body on a second side surface of the skirt body. On the first side surface of the skirt body, a size of a portion of the collapsing part protruding from the skirt body gradually decreases from the root to the edge part.
