  • Publication number: 20260108126
    Abstract: A cleaning device includes a hexagonal flat mop head and an articulating mop handle and that are geometrically configurable into a plurality of different cleaning positions with respect to linear handle axis to improve access to surfaces and corners of a restricted access controlled environment. To enable articulation of the mop handle, an articulating handle joint interconnects an upper handle segment and a lower handle segment so as to pivot with respect to a handle pivot axis that can be orthogonal to the linear handle axis. The cleaning device may also include a mop coupling enabling multiaxial movement of the flat mop head and the articulating mop handle.

  • Publication number: 20260108125
    Abstract: A cleaning module, including a first cylindrical core, a second cylindrical core arranged in parallel to the first cylindrical core, and a cleaning material disposed between the first cylindrical core and the second cylindrical core, the cleaning material being adapted to unroll from the first cylindrical core and roll onto the second cylindrical core. The cleaning module further includes a pressure tray arranged between the first and second cylindrical cores, the pressure tray being configured to apply a pressure against the cleaning material and thereby press the cleaning material against an exterior surface.

  • Patent number: 11465596
    Abstract: A system and method for cleaning a cart wheel includes an elongated body having a central channel having an entry end and an exit end. A shuttle slidably engages the elongated body and is engageable by a wheel entering the central channel from the entry end such that the wheel pushes the shuttle along the central channel and disengages the shuttle adjacent the exit end, wherein a sliding engagement between the wheel and the shuttle cleans the wheel.

  • Patent number: 11045064
    Abstract: A flat mop cover for mop-cover holder, where the flat mop cover comprises an elongate basic body. The basic body has a first elongate surface and a second elongate surface, which lie opposite one another. At least one foam-material layer is disposed between the elongate surfaces, and the two elongate surfaces are each configured to be cleaning surfaces. The two elongate surfaces are disposed such that a plate-shaped carrying element of a mop-cover holder is configured to be disposed in a sandwich-like manner between the two surfaces. The basic body is configured to absorb in a reversible manner at least four times, and at most twenty times, its dry weight in liquid, and wherein the foam-material layer has no fibers.

  • Patent number: 10918257
    Abstract: An insert for a mop includes a rail and a cleaning element at least partially disposed in an internal channel of the rail. Two protrusions are disposed on the body, each forming a leg connected to the body and a cylindrical wall defining an actuation bore connected to the leg. Each actuation bore is adapted to overlap a substantial portion of a tine, the tine being associated with a sponge mop having a hand lever that operates to pull the tine, the tine being disposed in the actuation bore and configured to impart a force onto the body through the actuation bore to pull the rail and the cleaning element through a set of rollers to wring out fluids that may be present in the cleaning element.
