Abstract

A self-wringing mop includes a handle, an operating sleeve, a mop head, and at least one blocking element. The handle includes a first longitudinal section having a polygonal cross-section with a plurality of edges running in an axial direction. The operating sleeve is twistably disposed on the handle so as to be twistable relative to the handle in a wringing direction and in an opposite direction. The mop head is disposed at a lower end of the handle and includes cleaning elements configured to be wrung out by a twisting in the wringing direction. The at least one blocking element protrudes radially inward from the operating sleeve toward the handle so that a twisting of the sleeve in the wringing direction results in the blocking element moving past the plurality of edges against an elastic force, and a twisting in the opposite direction results in at least one of the plurality of edges pressing the blocking element against the operating sleeve so as to block a further twisting in the opposite direction.
