| 1. A self-wringing mop, comprising:
a handle, the handle including a first longitudinal section having a polygonal cross-section with a plurality of edges running
in an axial direction;
an operating sleeve twistably disposed on the handle so as to be twistable relative to the handle in a wringing direction
and in an opposite direction;
a mop head disposed at a lower end of the handle and including cleaning elements configured to be wrung out by a twisting
in the wringing direction; and
at least one blocking element between the handle and the operating sleeve, wherein a twisting of the sleeve in the wringing
direction relative to the handle results in the blocking element moving past the plurality of edges against an elastic force,
and a twisting of the sleeve in the opposite direction relative to the handle 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;
the handle including a second longitudinal section having a different cross section from the first longitudinal section, the
operating sleeve being axially displaceable from a first position on the first longitudinal section to a second position on
the second longitudinal section, wherein the blocking element is disengaged and the operating sleeve is freely twistable relative
to the handle when the operating sleeve is in the second position.
