    Technical area
    The invention relates to a wiper strip for a squeegee of a floor cleaning machine, a squeegee for a floor cleaning machine for cleaning and / or disinfecting a floor with a liquid and a floor cleaning machine with such a squeegee and wiper strip.
    State of the art
    From DE 20 2013 103 571 U1 a ride-on floor cleaning machine is known. To clean the floor with a cleaning liquid, this floor cleaning machine is moved by a user. Cleaning liquid is dispensed along a cleaning path in the area of rotating bristles for cleaning the floor. Furthermore, the floor cleaning machine comprises a suction arrangement with a suction base, by means of which a cleaning liquor is sucked off the floor after cleaning the floor. This suction cup is arranged behind the bristles. The suction cup includes first and second lip arrangements. The cleaning liquor is partially dammed up by the first lip arrangement and passed through openings into a suction chamber located behind it. A second lip arrangement, which follows the first lip arrangement and forms the suction chamber, rests on the floor. The liquor collected in the suction chamber is completely suctioned off via a suction hose, so that a dry floor then remains behind the cleaning lane.
    The hygiene requirements for cleaning floors are increasing. In addition, infection prevention is required, particularly when cleaning floors in hospitals or other medical and non-medical areas.
    Presentation of the invention
    The invention is based on the object of proposing a wiper strip for a squeegee of a floor cleaning machine, a squeegee for a floor cleaning machine and a floor cleaning machine, which enables floors to be cleaned and / or disinfected.
    This object is achieved by a wiper strip for a squeegee of a floor cleaning machine, which has a wiper body with a fastening section for attaching the wiper strip to the squeegee, wherein the fastening section is part of the wiper body or is integrated into the wiper body or is provided on the wiper body and the wiper body comprises at least one wiper lip, which extends along a longitudinal side of the wiper body and which is formed at least from a moisture-adhering, moisture-distributing and / or moisture-absorbing material, the wiper body on the at least one end face along its longitudinal extension at least one bead as a wiper lip or several on one another Has lined up bristles as a wiper lip. With this at least one wiper strip arranged on the squeegee of the floor cleaning machine, when the floor to be cleaned is driven over, a film that is closed on the floor can be generated from the liquor remaining in the suction chamber of the squeegee. This wiper strip does not achieve complete suction of the liquor remaining in the suction chamber of the squeegee, but rather a small proportion of the liquor is evenly distributed on the floor by the wiper strip, so that a thin and closed film is formed. Particularly when using disinfectants or a cleaning agent with disinfectant, a disinfecting effect can be achieved through the targeted formation of the closed film.
    According to the first embodiment of the wiper strip, the wiper lip formed from bristles is preferably designed as a brush strip. This brush strip can have a fixed wiping body in which the individual bristles or bristle bundles are fixedly arranged or held clamped. The wiping body of such a brush strip can consist of plastic or metal. The bristles are mostly made of plastic. Alternatively, other materials can also be provided for this.
    In the further advantageous embodiment of the wiper lip as a bead, this bead can preferably be formed from a fleece, felt, fibers, loops, textile and / or a sponge. All these materials have the properties that the moisture can at least adhere to them and / or be distributed and / or the moisture can be absorbed. This promotes film formation. The at least one bead preferably extends continuously along an end face in the longitudinal extension of the wiper body.
    According to a further preferred embodiment of the wiper strip, the bead of the wiper lip and the wiper body of the wiper strip are formed from the same material. Simple manufacture can thereby be made possible.
    A preferred embodiment of the wiper strip provides that the wiper body is folded or turned over at least along its longitudinal side oriented towards the floor and the at least one bead is thereby formed as a wiper lip. The terminal strip preferably engages the at least one bead adjacent to the wiper body or supports the bead. The wiper lip designed as a bead can enable the film to be formed evenly, even on uneven surfaces of the floor.
    According to a further preferred embodiment of the wiper strip, the bead is designed as an L-shaped or arcuate section adjoining the wiper body. As a result, this wiper lip in the installed state on the suction cup can be aligned so as to lag in the direction of travel in a simple manner. This enables a larger contact surface and a better and more uniform distribution of the remaining liquor to achieve the closed film. Alternatively, the bead can be designed as a bottom segment-shaped or cylindrical section which is connected to the wiping body.
    This also makes it possible to achieve the same advantages as in the previous embodiment.
    The fastening section of the wiper strip is preferably designed as a clamping surface which can be fastened to a support of the suction cup with a retaining strip and / or a clamping strip. This enables a simple replacement and positioning of such a wiper strip for the support of the suction cup. In addition, existing suction feet can easily be retrofitted with such a wiper strip to form a wiper nozzle.
    Alternatively, the fastening section of the wiper strip can be designed as a holding and / or clamping strip which can be fastened to the support of the suction cup. This allows a reduction in the number of components for the suction cup.
    Furthermore, the fastening section can alternatively be formed from a Velcro or Velcro tape which can be connected to the carrier with a Velcro or Velcro tape. This enables quick attachment and quick release of the wiper strip on the squeegee.
    A further alternative embodiment of the fastening section of the wiper strip provides that the wiper strip can be connected to connecting elements, in particular pins, arranged on the carrier by a plurality of recesses provided in the wiper body. The pins can, for example, each be designed as a detachable fastening element, such as a clamping element, or can accommodate a screw, so that the wiper strip can be replaced without a tool.
    Furthermore, the fastening section of the wiper strip can alternatively be designed as a pocket in the wiper body, in which a holding and / or clamping strip can be inserted in order to fasten the wiper strip with the carrier on the suction cup.
    In addition, the fastening section of the wiper strip can alternatively be designed as a pocket which has an opening along a longitudinal side of the wiper body so that the wiper strip can be pulled over a holding and / or clamping strip and / or a rubber lip attached to the suction cup.
    Another alternative embodiment of the wiper strip provides that the fastening section on the wiper body has a profile at an end opposite the wiper lip, in particular in the form of a welt or for a tongue and groove connection that can be connected to the support of the suction cup. As a result, the wiper strip can be fastened by pulling in or pushing in the wiper strip on the carrier.
    Furthermore, the wiper body can be formed from a metal and the wiper lip can be held in a clamped manner. Alternatively, the wiper body can be made of plastic and / or elastomer and the wiper lip can be clamped and / or cast and / or encapsulated.
    Furthermore, the fastening section of the wiper body is preferably designed as a component for a force-fitting and / or form-fitting connection with the carrier on the suction cup, in particular as a component for a detachable latching, clip, bayonet, screw, clamp -, plug-in and / or pull-over connection.
    The object on which the invention is based is further achieved by a suction cup for a floor cleaning machine, in which the first and second lip arrangement form a wiper nozzle with a suction chamber, at least the second lip arrangement having at least one wiper strip according to one of the embodiments described above, which at Driving over the floor to be cleaned creates a film that is closed on the floor from the liquor remaining in the suction chamber. This wiping nozzle thus enables a closed film that remains on the floor to be produced in a targeted manner, in particular after driving over a cleaning path. The film is advantageously produced from a liquid which comprises a combination of a cleaning agent for cleaning the floor and a disinfectant or just disinfectant. The targeted formation of the closed film enables it to remain on the floor for at least thirty seconds, thereby achieving the disinfecting effect.
    The second lip arrangement preferably has at least one wiper strip with at least one wiper lip which receives a portion of the liquor, distributes it and / or to which a portion of the liquor adheres. The closed film can be achieved through this configuration of the at least one wiper lip. Complete wiping of the liquor from the floor using a wiper lip or a doctor blade and complete suction of the liquor is specifically not provided. Rather, the wiper lip is intended to form a film from the liquor still remaining in the suction chamber and not sucked up. For this purpose, the wiper lip is preferably formed from a moisture-adhering and / or moisture-absorbing material.
    Furthermore, the at least one wiper strip can preferably be fastened directly to a carrier of the suction cup or with at least one clamping bar to the carrier or between a retaining bar and a clamping bar to the carrier of the suction cup. The at least one wiper strip is preferably fastened to the carrier in an exchangeable manner via the fastening strip. For example, a clamp or screw connection can be provided. A simple change and attachment can thus be made possible without additional tools. In addition, such a wiper lip can be retrofitted with the at least one fastening strip on already existing suction feet.
    Another preferred embodiment of the second lip arrangement provides a first wiper strip leading in the direction of travel and at least one second wiper lip lagging behind the first wiper strip. The first wiper strip and the at least one subsequent second wiper strip preferably have different permeability with regard to the liquor. Thus, for example, the leading wiper strip can enable permeability and a coarse distribution of the remaining liquor and the at least one trailing wiper strip can form a uniformly closed film.
    To form the wiper nozzle, the first lip arrangement preferably has a lip with a pull-off edge, which comprises several interruptions and is preferably fastened to the carrier with a terminal strip, in particular exchangeable. These interruptions are each offset inwardly viewed from an outer right and left edge of the cleaning path and, due to the preferably sickle-shaped alignment of the lip, allow the liquor to be transferred to a central area of the suction chamber for suctioning off a portion of the liquor. This lip of the first lip arrangement is preferably made of a soft plastic material so that the peeling edge rests on the floor and has a good peeling effect and supply of the liquor, in particular through the interruptions, into the suction chamber. A small proportion of the liquor within the suction chamber remains on the floor in order to form the closed film on the floor by means of the second lip arrangement. This dries off after a short time.
    The object on which the invention is based is furthermore achieved by a floor cleaning machine for cleaning and / or disinfecting a floor with a liquid, in which a suction cup according to one of the embodiments described above is provided. Such a floor cleaning machine is preferably designed as a ride-on cleaning machine. As a result, the closed film formed by the suction cup can remain on the floor or on a cleaning path for a short time without the floor cleaning machine running over it or an operator stepping into the film before it is dried. The floor cleaning machine can preferably also comprise a work tool, such as brushes, by means of which the floor is cleaned along a cleaning path. The suction cup extends in particular transversely to this cleaning path.
    Furthermore, the suction cup is preferably guided along the cleaning path with its own weight resting on the floor. This enables a simple structural design of the floor cleaning machine.
    Furthermore, a continuous, but not complete, suction of the liquor is preferably provided during a cleaning trip in which the liquid for cleaning and disinfecting the floor is constantly being dispensed. As a result, a certain proportion of the liquor is sucked off and a remaining proportion of the liquor remains for permanent moistening of the wiper nozzle, in particular of the at least one wiper lip of the second lip arrangement.
    The liquid used for the floor cleaning machine advantageously comprises a portion of a cleaning agent and a portion of disinfectant. This means that increased hygienic requirements can be met. The liquid can also only be a disinfectant.

    Ways of Carrying Out the Invention
    In Figure 1, a schematic view of a floor cleaning machine 10 is shown. FIG. 2 shows a view from the rear. This is, for example, a ride-on floor cleaning machine which comprises driven wheels 12, in particular a pair of wheels, and a steerable wheel 14 on a housing 17. The wheels 12 are driven by a motor, not shown in detail, which is provided within the housing 17. The housing 17 furthermore comprises a seat 18 for an operator and a steering wheel 19 for controlling the steerable wheel 14. Control elements 21 for controlling the floor cleaning machine 10 are arranged adjacent to the steering wheel 19.
    For cleaning a floor 11, such as, for example, a hard covering made of stone, tiles, plastic or the like, the floor cleaning machine 10 brings a liquid onto the floor 11 via an outlet 23 from a storage container 22. For example, water with the addition of a chemical cleaning agent and / or a disinfectant can be used as the liquid. To clean the floor 11, the floor cleaning machine 10 comprises a working tool 24. This can be embodied, for example, as a pair of brushes made up of two brushes, in particular disc brushes. If the working tool 24 is arranged in pairs, these can be arranged offset from one another in the direction of travel 26 and preferably driven by a drive 25. Instead of two disc brushes, only one or more than two disc brushes as well as roller brushes or drive plates with pads can be provided. In the following explanations, reference is made to brushes as work tools 24 by way of example.
    The liquid is dispensed in front of the brushes 24 and / or in a region of the brushes 24 during the operation of the floor cleaning machine 10. The brush 24 brushes the floor 11 along a cleaning path with the liquid.
    Seen in the direction of travel 26 behind the pair of brushes 24 or in the rear region of the floor cleaning machine 10, a suction arrangement 31 is arranged. This suction arrangement 31 is shown in a non-use position 33. This rests on the floor 11 in a working position. The liquid remaining after cleaning with the brushes 24 is referred to as liquor and is a mixture consisting of the liquid dispensed and the dirt that has loosened from the floor 11 as a result of the brushing. This liquor is sucked off from the floor 11 via the suction arrangement 31.
    The suction arrangement 31 comprises a suction cup 34, which is shown in more detail below in FIGS. 3 to 5.
    This suction cup 34 extends transversely to the direction of travel 26 and preferably has a width which corresponds to a cleaning path formed by the pair of brushes. The suction cup 34 can also be accommodated in a pivotable manner. A swivel arm arrangement 35 can advantageously be provided between the housing 17 and the suction cup 34.
    The suction cup 34 comprises a support 40, at the outer end of which, in particular on a support plate 42 of the support 40, deflector elements 41 or rollers are provided, which prevent the suction cup 34 from impacting against side walls while driving along the side walls or when cornering to or away from a sidewall. These deflector elements 41 can furthermore limit the pivoting range of the suction cup 34.
    In addition, support rollers 43 are advantageously provided on the carrier 40, in particular on a carrier plate 42 of the carrier 40, which are preferably adjustable in height so that the suction cup 34 can be positioned at an optimal distance from the floor 11.
    On the carrier 40, a connection 46 is also provided, to which a suction hose 47 can be connected. A suction chamber (FIG. 5) is formed within the suction foot 34, via which the liquor is sucked in and fed to a dirty water container 39 in the housing 17.
    In FIG. 3, a view of the suction cup 34 pointing in the direction of travel is shown. FIG. 4 shows a perspective rear view of the suction cup 34. In FIG. 5, a perspective view of the suction cup 34 according to FIG. 3 is shown. FIG. 6 shows the carrier 40 from below, from which, for example, a second lip arrangement 61 has been removed. In the middle area of the carrier 40, the connection 46 for the suction hose 47 is provided. The connection 46 in the carrier 40 opens into a suction chamber 48 which is designed to be open at the bottom.
    Adjacent to this, a quickly releasable clamp fastening is provided in order to fasten the carrier 40 to the swivel arm arrangement 35 of the housing 17 or to a further connection plate of the housing 17.
    The carrier 40 comprises a carrier foot 44. On the carrier 40, in particular on the carrier foot 44, a first lip arrangement 51 and a second lip arrangement 61 are provided. These lip arrangements 51, 61 and an underside of the support foot 44 form the suction chamber 48, which is open towards the base 11. At least one suction opening 45 is provided in the support foot 44, which opens into the connection 46. The support foot 44 has, for example, a sickle-shaped contour in its longitudinal extension. The lip arrangement 51, 62 can be provided, preferably detachably, on each outer side of the support foot 44. The first and second lip arrangements 51, 61 are preferably arranged in a crescent shape to one another, that is, the respective outer ends of the lip arrangements 51, 61 abut one another, and a wider section is provided in the central area, the width of which is equal to or smaller than the connection 46 can. Alternatively, the first and second lip arrangements 51 and 61 can also be arranged in a straight line to one another, the support foot 44 having a corresponding contour.
    The first lip arrangement 51 on the suction cup 34 is provided in advance of the second lip arrangement 61 in use. This first lip arrangement 51 comprises a lip 52 which is fixed to the carrier 40 via a clamping strip 53. Detachable fastening elements 54 are preferably provided. These can be designed, for example, as simple wing nuts, so that the lip 52 can be detached without the aid of a tool. The lip 52 preferably has a pull-off edge 56. A plurality of interruptions or recesses 57, which form inlet openings for the liquor into the suction chamber 48, are provided on the pull-off edge 56.
    The first lip arrangement 51 and the second lip arrangement 61 form a wiper nozzle 71. This wiper nozzle 71 on the suction cup 34 enables a closed film from the liquor to remain on the floor 11 when the wiper nozzle 71 moves over the cleaning path after the wiper nozzle 71 . When using a liquid which, among other things, includes a disinfectant, the disinfectant can act over a longer period of time, preferably between thirty seconds and ten minutes, due to the formation of the film, until this film dries off. This enables the disinfection effect to be achieved and the hygiene requirements to be met.
    In FIG. 7, a first embodiment for forming a wiper nozzle 71 is shown in perspective.
    The second lip arrangement 61 comprises at least one wiper strip 60 with at least one wiper lip 62. The second lip arrangement 61 is positioned following the pull-off edge 56. This at least one wiper lip 62 of the second lip arrangement 61 is preferably designed differently from the pull-off edge 56 of the first lip arrangement 51.
    The wiper strip 60 comprises a wiper body 66 on which the at least one wiper lip 62 is provided. At least one fastening section 63 is formed on the wiper body 66. This fastening section 63 can be attached to the wiper body 66 or fastened thereto. The fastening section 63 and the wiper body 66 can also consist of one part.
    In this embodiment in FIG. 7, the wiper strip 60 is formed as a wiper lip 62 by a brush strip made of several bristles lined up in a row. These bristles are received by the fastening section 63. This fastening section 63 is formed in one piece with the wiper body 66. This can preferably be made of a plastic material or elastomer or else metallic. The wiper body 66 is, however, bendable to the extent that it can assume the contour, as shown in FIG. As a result, the fastening section 63 can be brought to bear against an outside of the carrier foot 44. This wiper strip 60 can be fastened to the carrier 40 directly or preferably via a terminal strip 64. Detachable fastening elements 54, such as wing nuts, are advantageously provided. Alternatively, the wiper strip 60 can also be provided with a clamp fastening in the form of a clip or latch connection or a tensioning connection for quick release and fixing on the carrier 40 or on a carrier foot 44 or retaining strip 68, for example made of plastic or steel, provided on the carrier 40. The fastening section 63 is preferably received on a plurality of spaced apart pins 49 on the support foot 44 which engage the fastening section 63 in the individual openings 65. The fastening elements 54 engage the pins 49 in order to fix the terminal strip 64 and the wiper strip 60 to the carrier 40.
    The design of the individual bristles with regard to the length and / or the density over the length and / or the width of the fastening strip 63 is designed in such a way that, on the one hand, allows sufficient suction in the suction chamber 48 to suck off a certain portion of the liquor and, on the other hand, a closed film is formed over the width of the second lip arrangement 61, which film still remains after the suction cup 34 has passed over the floor 11.
    In FIG. 8, a schematic sectional view along the line IV-IV in FIG. 4 is shown. The front ends of the brush strip, which form the wiper lip 62 of the second lip arrangement 61, are preferably provided at the same level as the pull-off edge 56 of the lip 52 of the first lip arrangement 51. Alternatively, it can also be provided that the wiper lip 62 protrudes further in height in the direction of the floor 11 opposite the pull-off edge 56, as a result of which the bristles rest on the floor 11 in a curved manner. This makes it possible for a small proportion of liquor to build up in front of the bristles, so that uniform and permanent moistening of the floor 11 on the one hand and a targeted exit of the liquor to form the film behind the second lip arrangement 61 on the other hand is enabled.
    An alternative embodiment of the wiper strip 60 provides a fastening section 63 on the wiper body 66, which is formed, for example, by a Velcro or Flaus tape so that a loop or Velcro tape is fastened to the support foot 44 in order to fix the wiper strip 60 to the support 40 . Alternatively, a receptacle can be provided on the carrier foot 44 of the carrier 40 so that the wiper body 66 with its fastening section 63 can be inserted therein or that the wiper body 66 can be fastened with the fastening section 63 on the carrier foot 44 by a clip and / or latching connection. A pull-over fastening can also be provided. In this case, the fastening section 63 is designed as a pocket in the wiper body 66, which has an opening along a longitudinal extension of the wiper body 66 and the wiper lip 62 opposite, so that this opening can be pulled over a corresponding strip on the carrier foot 44 and preferably with a Velcro fastener, snap fastener, loop straps or the like can be secured.
    The first wiper lip 62 according to FIG. 7 can have a strip made of a fleece, a felt, fibers or loops, a textile or a sponge instead of a brush strip with several bristles arranged in a row.
    Two or more wiper lips 62 in a wiper strip 60 can also form the second lip arrangement 61. A plurality of wiper strips 60 can also form the second lip arrangement 61 in a row. At least one wiper strip 60 can also form the first lip arrangement 51 and at least one wiper strip 60 can form the second lip arrangement 61 for a wiper nozzle 71. The wiper strips 60 can comprise one of the above embodiments and can also be designed differently from one another to form the lip arrangement 51, 61.
    In FIG. 9, an alternative embodiment of the suction cup 34 to FIG. 3 is shown. FIG. 10 shows a perspective illustration of the suction cup 34 according to FIG. 9 with an alternative structure of the second lip arrangement 61. FIG. 11 shows a schematic sectional view along the line XIII-XIII in FIG.
    In this embodiment, the wiper strip 60 is formed from a single material, that is, the wiper lip 62 and the wiper body 66 consist of the same material. The fastening section 63 is thus part of the wiper body 66. In this preferred embodiment, the wiper body 66 and the wiper lip 62 are formed, for example, by a strip made of a fleece, fibers, felt, a textile, a fringe or loop arrangement or a sponge. To fix the wiper strip 60, a clamp to the carrier 40 is provided. For example, the wiper body 66 can only be received by a terminal strip 64 or between a retaining strip 68, which advantageously acts directly on the carrier 40, and clamped to the carrier 40 with a terminal strip 64. The fastening elements 54 can be designed analogously to the embodiment according to FIG. The alternatives to the detachable fastening described in relation to FIG. 6 can also be provided.
    In this embodiment according to FIG. 8, the wiping body 66 preferably has a bead 69 at least along its longitudinal side aligned with the base 11. This bead 69 can be formed by a kind of thickening of the material or the fastening section 63 is tapered compared to the widened bead 69. Alternatively, this bead 69 can also be formed in that a strip of the material to form the bead 69 is turned over along the longitudinal side. This bead 69, which is preferably integrally connected to the fastening section 63, can also be formed by pressing a thicker strip of the respective material or by machining it away from the material. The bead 69 can, for example, have a semicircular or three-quarter circular or circular cross section. Other geometries are also possible. This bead 69 can also be designed as a curved segment or as a curved strip. As a result, an enlarged contact surface and a uniform configuration of the film can be achieved by means of the wiping nozzle 71. The wiper body 66 advantageously comprises a bead 69 each on its upper and lower longitudinal side. As a result, the wiper strip 60 can be rotated and reused after the one bead 69 has worn off, in order to align the second bead 69 with the floor.
    Furthermore, one or more wiper strips 60 made of different materials can alternatively be lined up and fastened to the carrier 40 by a clamp fastening or a retaining strip 68 to the carrier 40. A further holding strip 68 can also be provided between two wiper strips 60, so that a wiper strip 60 is held between a holding strip and / or a clamping strip 64 or between two holding strips 68 or two clamping strips 64. The retaining bar 68 and / or the clamping bar 64 can be made of steel and / or plastic and / or elastomer. By means of the retaining strip 68 and / or the clamping strip 64, it is also possible for the wiper lip 62 to rest in a targeted manner and / or to rest on the floor 11. The wiper strip or strips 60 are preferably wider than the clamping strip 64 and / or holding strip 68. The clamping strip 64 can also have a curved contour pointing towards the floor, the lower edge being aligned so as to allow the wiper lip 62 to rest in a targeted manner on the floor 11.
    In FIG. 12, a perspective view of an alternative embodiment of the wiper strip 60 is shown. FIG. 13 shows a schematic sectional view of the wiper strip 60 according to FIG. 12. In the case of this wiper strip 60, it is provided that it consists of a fleece, a felt, a textile, a loop material or a fabric.
    For example, this material can be turned over or folded so that a bead 69 is formed as a wiper lip 62. As shown in the exemplary embodiment, the wiping body 66 can be designed in two layers. As an alternative, the wiping body 66 can also be designed only in one or more layers. The bead 69 is preferably designed as a curved section of the wiper body 66. The bead can also be L-shaped or segment-shaped and connected to the wiper body 66. On an outside of the wiper body 66, a fastening section 63 is provided, on which a Velcro connection 81 is provided. For example, a Velcro or loop tape can be provided on the fastening section 63. The complementary tape for forming the Velcro connection 81 is provided on the carrier 40, in particular on an outside of the carrier foot 44 or on a retaining strip 68. In this embodiment, for example, the terminal strip 64 can be omitted. However, this terminal strip 64 can also be provided for securing purposes. Breakthroughs 65 can also be provided in the wiper body 66 so that this wiper strip 60 can be positioned relative to the pins 49 of the carrier 40 and fixed with fastening elements 54 if such pins 49 are provided on the carrier foot 44.
    In FIG. 14, a further alternative embodiment of the wiper strip 60 is shown in perspective. FIG. 15 shows a schematic sectional view of the wiper strip 60 according to FIG. 14. In this embodiment, it is provided that the wiper strip 60 is pocket-shaped, so that this pocket-shaped wiper strip 60 extends from the floor over a section on the carrier 40 or over a retaining strip 68 on the carrier 40 can be pulled over. For example, a Velcro or Velcro tape can be provided on both sides of a strip-shaped retaining section of the retaining strip 68, so that a Velcro or Velcro tape, which is provided on an inside of the pocket of the wiper body 66, can be attached to it. It is provided that the wiper strip 60 is positioned in relation to the holding strip 68 in such a way that holding tabs 77 protrude freely on its upper end face opposite the wiper lip 62 and can be fastened to the pin 49 of the support foot 44, for example. These retaining tabs 77 on the retaining strip 68 can also be correspondingly adapted to other fastening systems of the respective carrier foot 44.
    In FIG. 16, an alternative embodiment of the wiper strip 60 to FIG. 14 is shown. FIG. 17 shows a schematic sectional view of the wiper strip 60 in FIG. 16. In this embodiment, a pocket-shaped wiper body 66 is also provided. The retaining strip 68 is inserted into the pocket of the wiper strip 60. Sections 78 of the wiper body 66 extend between the retaining tabs 77 of the retaining strip 68. These sections 78 of the wiper body 66 can be connected to one another by a Velcro connection 81 provided in between in order to fix the pocket-shaped wiper strip 60 on the retaining strip 68. Alternatively, pushbuttons or other latching or clip connections can be provided between the sections 68 of the wiping body 66 for quick fixing and releasing.
    In FIG. 18, a perspective view of a further alternative embodiment of the wiper strip 60 is shown. 19 shows a sectional view of the wiper strip 60 according to FIG Fastening sections 63 is fastened to the part of the retaining strip 68 inserted therein. Outside the wiper body 66 and opposite the wiper lip 62, the retaining strip 68 has a profile 84, for example in the form of a welt. This profile 84 can be inserted or retractable in a profile receptacle 83. This profile receptacle 83 can form a second component of the retaining strip 68. This profile receptacle 83 can also form a section on the support foot 44 which is attached or integrated thereon.
    The profile receptacle 83 and the profile 84 are adapted to one another so that simple pulling in or insertion is possible. A lateral fixation against pulling out can be carried out by a form-fitting delimitation on the profile receptacle 83 or on the profile 84. A second form-fitting delimitation can be designed on the opposite side as a sliding or swiveling bolt. Furthermore, sliding or swiveling bolts that can move on both sides can also be formed.
    As an alternative to a round profile cross-section according to the profile 83 shown, a square or polygonal or T-shaped cross-section or another geometry that deviates therefrom can also be provided.
    Due to the design of the at least one bead 69 on the wiper strip 60, an enlarged contact surface on the floor is made possible for evenly distributing the liquor remaining in the suction chamber 48 of the suction cup 34 in order to form a closed film. Furthermore, this configuration of the wiper strip 60 has the advantage that uneven floors can be leveled out. In addition, by adjusting the height of the wiper strip 60 relative to the suction cup 34, the remaining amount of the liquor on the floor can be adjusted in a simple manner.
    In FIG. 20, a perspective view of an alternative embodiment of the suction cup 34 is shown. In this embodiment, a wiping cloth 73 is assigned to the wiping nozzle 71. This wiper 73 can be provided interchangeably on a holding device 75 by means of a clamp fastening. The holding device 75 can be fastened to the carrier 40 by means of a clamp, latch, clip connection or a releasable screw connection or bayonet connection. This wiper 73 can be formed from a fiber material, from textile, from bristles, a nonwoven material, fringes and / or loops and / or a sponge. This wiper 73 can be provided in addition to the wiper nozzle 71. Alternatively, this wiper 73 can also be attached to a suction cup 34 by means of the holding device 75, in which the second lip arrangement 61 instead of the wiper lip 62 has a lip which is permeable to a small proportion of the liquor without forming a closed film. This closed film is then formed by the wipe 73.
