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.

Abstract: A thermoformable decorative material for an automotive interior includes: a decorative layer including a textile substrate; a digitally printed design disposed on at least one side of the textile substrate and having dispersion ink and/or pigment ink; and an overlay adhesive coating applied to the digitally printed design. The overlay adhesive coating has an adhesive that includes polyurethane and/or polyacrylate.
Abstract: A beveled broom and step-on dustpan cleaning system including a step-on dustpan having a step-on portion configured to allow a user to collect debris in a receptacle of the dustpan when a force is applied on the step-on portion. The dustpan includes a lip portion which is configured to seal against a floor surface upon a user stepping on the step-on portion to collect debris. A beveled broom having a broom head configured with a beveled or chamfered shape at a functional angle to provide an effective and efficient contact surface to a floor surface to collect debris during use.
Abstract: A sealing bellows includes a casing. The casing includes a rubber-elastic material, which includes an edge region at the front side on both sides. A clamping ring for fastening the sealing bellows to a machine element is arranged in at least one of the edge regions. The clamping ring is formed by an annular disk which, viewed in the circumferential direction, has a meander-like configuration.
Abstract: A bucket assembly for use with a mop includes inner and outer bucket assemblies including first and second reservoirs, respectively. The inner bucket assembly includes a rinse bucket, fluid connection and closure element between the rinse bucket and the first reservoir. The first reservoir is optionally otherwise sealed when the at least one closure element is in the open position. The inner bucket is disposed at least partially within the second reservoir. A drainage channel fluidly connected to the second reservoir is formed by at least one of the inner bucket assembly and/or the outer bucket assembly.
Abstract: A method includes using a sealing element to dynamically seal a sealing body in the presence of a lubricant. The sealing element has an elastomeric base body and a plasma coating. The coating includes the elements carbon, oxygen, silicon, and hydrogen. The coating has the following properties at least at the surface: the amount ratio C:Si (at %/at %) is >5, the amount ratio O:Si (at %/at %) is >3, and the surface energy is <50 mN/m. In an embodiment, the coating includes the element fluorine.

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 cleaning device includes: a main body having a front edge; a suction device having a suction opening and a suction channel; a brush assembly having a rotatable roller brush; and an apparatus for wetting a floor to be cleaned with liquid, the apparatus being associated with the roller brush. The suction opening and the roller brush are arranged in the main body in such a manner as to face the floor to be cleaned. The suction opening has a first wall facing the front edge of the main body and a second wall facing the roller brush. The roller brush loosens dirt from the floor to be cleaned. A pivotable lip is associated with the suction opening and alternately rests against the first wall or the second wall.
Abstract: A cleaning system includes: a bucket; a cleaning device with a mop head, the mop head including a carrier body and cleaning fringes that are fixed to the carrier body, the carrier body being connected to a stick on its side facing away from the cleaning fringes; and a washing-out device arranged in the bucket for washing out the cleaning fringes, the washing-out device including a basket settable into an upward and downward movement by a first actuating device, and a spinning device arranged in the bucket for spin-drying the cleaning fringes, the spinning device including the basket, which is settable into rotational movement by a second actuating device, and a centering pin, which is arranged in the basket and centers the cleaning device. The carrier body is essentially disk-shaped, with a circumferential boundary and with a maximum extension d1 between two circumferential areas opposite to each other.
Abstract: A floor mop including a handle, a shaft coupled to the handle, a multidirectional joint coupled to the shaft opposite the handle, and a mop plate. The mop plate is unitarily formed and includes an upper plate including an upper surface, a substantially parallel lower plate including a lower surface, lateral faces extending between the upper and lower plate, and at least one internal web extending between the upper and lower plates. The upper plate, lower plate, lateral faces and at least one internal web are unitarily formed. The mop plate and the multidirectional joint further include complementary coupling structures.
Abstract: A sensor element includes: a supporting body; and a sensor body, the sensor body being planar in shape, being made of an elastic material, and having a first surface and a second surface coated so as to be electrically conductive. The sensor body includes a measuring segment and a fastening segment. A layer thickness of the fastening segment is greater than a layer thickness of the measuring segment.
