Abstract: A bucket includes: at least two chambers which are flow connected to one another by at least one overflow channel. One of the chambers is a combined washing-out/centrifuging chamber for a cleaning device. One of the chambers is a water level-regulating chamber configured to regulate a water level in the washing-out/centrifuging chamber. The water level-regulating chamber contains a displacement body which is movable by a first actuating device.

Abstract: In an embodiment, the present invention provides a torsion wringer including: a contraction device for receiving a mop head of a mop, the contraction device having an upper part and a lower base which are interconnected by contraction lamellae, the contraction lamellae being hinged to the upper part and to the lower base such that the upper part can rotate relative to the lower base, the contraction device being movable relative to a carrier device over a distance of travel, as a result of which the upper part rotates through an angle of rotation relative to the carrier device and relative to the lower base. A reduction unit is provided so as to reduce a force which counteracts the rotation of the upper part.

Abstract: A nonwoven includes: framework fibers; an at least in part fused thermoplastic material; and a thermally embossed mesh pattern having a plurality of intersecting embossed grooves, between which a plurality of embossed elevations are arranged. At least the framework fibers are staple fibers. An equivalent diameter of the embossed elevations is smaller than 50% of a fiber length of the framework fibers. A ratio of a width of the embossed grooves to a thickness of the nonwoven in a region of the embossed elevations is less than or equal to 4/5 A ratio of the width of the embossed grooves to a thickness of the nonwoven in a region of the embossed grooves is from 0.5 to 2.
