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: 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.

Abstract: A linear textile structure has at least two strands, wherein a first strand has microfibers and a second strand encloses the first strand, wherein the structure may provide a stable linear textile structure, by which the most effective cleaning possible can be achieved with minimum effort. Both strands can be brought into contact together at least in some sections and simultaneously with a surface to be cleaned.

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 mop cover has a planar main body with four outer edges, wherein a longer first outer edge is oriented parallel to a longer second outer edge, the first outer edge being longer than the second outer edge, two shorter outer edges respectively extending between the longer outer edges, the main body having at least two pockets, into which mop wings or tensioning elements can be introduced to tense the planar main body, being configured such that the mop cover can be readily gripped, and tensioned, by rectangular wings, wherein the mop cover can be guided effectively for cleaning purposes with the greatest possible degrees of freedom in corner regions, a mop cover of the type mentioned in the introduction is characterized in that at least one outer edge and/or at least one pocket are/is assigned at least one stiffening element for the partially reinforced stiffening of the main body.

Abstract: A torsion wringer has a receiving device for receiving the head of a mop, the receiving device having an upper part and a lower part which can be interconnected by elements. The design and to development of the torsion wringer can provide a mop that can be freed from liquid in a problem-free manner. The torsion wringer has elements designed in such a manner and/or are articulated on the parts of the container such that the parts can be rotated with respect to each other.
