Description

Mop cover

The invention relates to a damp mop covering which has a textile fabric with at least one cleaning-active side and two holder insertion pockets arranged on the back to the cleaning-active side.

Cleaning textiles or structures as well as mop covers currently consist mainly of cotton and plastic fibers. Mostly there are mixtures of both basic components. This is necessary because some types of textile have opposite properties and a mop cover only enables maximum performance if many positive properties are combined in it. The water suction power of cotton is approx. 250%, that of plastic fibers practically 0%. The dirt-bearing capacity of cotton is good, while that of plastic fibers, with the exception of micro or polypropylene fibers, is poor. The abrasiveness of cotton is very low, while that of plastic fibers is high. Cotton, polyester and polypropylene are washable up to 95 ° C, but the washing stability of cotton is poor, while that of polyester and polypropylene is good. Cotton has a strong shrinkage, while plastic fibers hardly shrink. The gliding behavior of cotton is poor, while that of synthetic fibers is good.

On their top, d. H. the side facing away from the floor when wiping, damp mop covers or damp mops usually consist of a cover sheet, side bias tapes or seams and attached holder insertion pockets. The material requirements for these components of a damp mop cover are high washing stability, extreme tear resistance, low shrinkage and good shape stability with simultaneous elasticity during the washing process.

The active cleaning side, ie the side facing the floor during the wiping process, of a damp mop cover usually consists of fringes, loops, Shag or slats. This or this side should have a high suction or water absorption capacity, the largest possible dirt absorption capacity and dirt retention capacity, smooth-running sliding behavior, excellent washing stability and the highest possible resistance to fluff release.

Since these technical requirements are varied and in some cases contradicting each other, flat mop covers are made from a large number of individual components with different properties by sewing.

For the cover sheets, the holder pockets and the bias tapes, there are usually fabrics made of pure polyester or blended yarns, e.g. B. 75% polyester and 25% cotton, use. For these components of a damp mop cover, the focus is on the greatest possible stability with low absorbency. With these fabrics it is necessary to sew the warp directions in the main tensile stress.

Mixed yarns consisting of 50% polyester and 50% cotton are generally used for the fringes, loops or shag. The polyester content favors the gliding behavior of the cleaning-active side, whereas the cotton causes the absorbency and dirt adhesion of the cleaning-active side. Open fringes are distinguished from loops by greater dirt adhesion and more spontaneous suction. On the other hand, open fringes, on the other hand, create greater frictional resistance when wiping and give off more fluff.

The fringes or loops are sewn to the cover sheet. There is a risk that the fringes or loops will come loose from the cover sheet after repeated use of a damp mop cover. In the case of the loops consisting of endless threads, there is a possibility of fastening them after the so-called tufting process with the cover page. This leads to perforation of the cover sheet and thus a reduction in its tear resistance.

Since the cover sheet is usually a woven fabric, it must be edged with bias tapes or surrounded by a hem seam in order to prevent the fabric structure from disintegrating and dissolving during use of a damp mop or damp mop cover. Furthermore, damp mops usually have a fringe ring running around the outside in order to be able to clean abutting surfaces delimiting the respective wiping surface near the edge. Furthermore, the cotton portion in the cleaning-active side is exposed to heavy wear due to the friction effect that occurs during wiping.

Overall, therefore, the manufacture of flat mop covers is relatively complicated and expensive. In particular, many capital-intensive machines, such as a fringe ribbon folding machine, fringe ribbon sewing machine, trimmings laying machine (textile edging) and trimmings sewing machine, a sewing machine for internal fringes, a tufting machine, pocket punching and pocket sewing machine, pocket sewing machine and a machine for end seams are required for automatic assembly. Such a large number of machines is not only capital-intensive, but due to the large number of individual production steps also leads to the entire production process being susceptible to malfunction, which has not previously been possible with fully automated production.

The main disadvantages of the previous wet mop covers, also referred to as flat mop covers or wet mops, are in the reduced stability of the cover sheet due to its perforation when sewn with the trim elements on the active cleaning side, in the poor adhesion of the bias binding and the associated fraying of the cover sheet in the loosening the loops of the cover sheet, the fraying and the lint dispensing. Cleaning water serves as a means of transport for the loosened and dispersed dirt. In practice, limits are shown here, since cotton absorbs only 250% of its own weight in water and, moreover, a pure cotton fabric is very unfavorable because of its poor sliding behavior and its instability when washing. In the case of blends of cotton and plastics, properties such as abrasiveness, shrinkage, sliding behavior and washing stability can be adapted to many needs by appropriate selection of the material proportions, but the water suction power is in any case lower than 250% when using different blended materials.

A flat mop cover for the maintenance of hard floor surfaces, consisting of a carrier fabric, on which material sections are sewn on the underside and on which upper side insert pockets are sewn on, is known from DE 38 09 279 C1. This describes a damp mop cover for floor care, which consists of a preferably textile carrier fabric with holder insert pockets sewn on top on the longitudinal ends and with material attached on the underside to absorb dirt and moisture. It has a low weight, good absorbency and a large water storage capacity. The underside material in the form of sponge or non-woven cloth material with a high liquid absorption capacity is attached in the form of several strips arranged in a row next to one another, the strips being fastened in regions to the carrier fabric by sewing on. The water absorption capacity of the material made of sponge or fleece cloth arranged side by side is up to 3,600 g / m3, whereby the water absorption capacity is determined according to DIN 53 923 and the relative water absorption of the sponge or fleece cloth material is up to 1,400%.

The flat mop cover according to DE 38 09 279 C1 can, however, still be improved. The fact that the strips of sponge or fleece material with are sewn to the backing material, the reversible drying shrinkage of 30% compared to the wet state leads to considerable problems in handling the flat mop covers. When wet, the covers show the calculated length dimension, the cover sheet made of carrier material being flat. When dry, the sponge cloth lamella shrinks by approx. 30% compared to the cotton / polyester cover sheet, which leads to extreme warping. Wipers can therefore no longer be easily inserted into the covers. If the wipers are still forced into the holder insert pockets, this will result in damage. If the covers are first moistened before being attached to the wiping devices, the wiping devices can be inserted, but this is associated with considerable time and handling. Another disadvantage is that sewing the material around the seams significantly reduces the water absorption capacity of the material.

An improvement in the water absorption capacity or the water suction power has been achieved, for example, in the above-mentioned patent DE 38 09 279 C1 by using a sponge or nonwoven cloth material with a high viscose content in addition to cotton and plastic. Other water-absorbing materials, such as sponge or wood, act by filling the voids in the dry state with air and displacing the air from the voids when the materials are immersed in liquid. However, this liquid absorption requires the material to be immersed in the liquid. This complicates the absorption of cleaning liquor from hard floor surfaces. Even with a residual amount of 15 g of cleaning liquor per square meter, which is unacceptable wetness for coated PVC floors, for example, the thickness of the moisture film on the floor is only a fraction of a millimeter, and the material can hardly be immersed in the liquid to any significant extent. A different form of water absorption capacity, which can be described by the water absorbency, is therefore required for a mop cover that holds the cleaning liquor. Here, the material fetches the liquid via the suction effect at the contact interfaces, so that the liquid is literally absorbed. While a remainder of 15 g of cleaning liquor per square meter on hard floor surfaces is unacceptable wetness, one is

2 aim for a remaining liquor quantity of 10 g / m. It has been observed that with a residual moisture content of 11 g / m, the cleaning performance drops suddenly.

This negative jump is explained by the free mobility of the pigment dirt in the relatively higher moisture film on the wiping surface. This option is switched off below 11 g / m. The dirt can no longer avoid the wiping materials, but rather adheres to the material on the active cleaning side during the wiping movements and can be removed in this way.

The invention is therefore based on the object of creating a damp mop cover which has improved cleaning performance and ease of handling with reduced manufacturing outlay.

In the case of a damp mop cover of the type mentioned at the outset, this object is achieved in that the at least one active cleaning side consists of a knitted fabric made of plastic microfibers, on the back of which at least one absorbent pad made of plastic material is arranged.

The invention thus initially creates the possibility of designing and arranging the (primarily) absorbent material in the form of a suction pad at a different location than on the floor-facing, cleaning-active side and regardless of the areas or sections with (primarily) cleaning-active material. The (highly) absorbent material is now formed and arranged on the rear side of the active cleaning surface. Since the necessary water absorption function, ie the water suction and Water storage function is now essentially separated from the cleaning function, the cleaning-active material could be designed specifically for its cleaning-promoting effect, the water absorption effect or absorbent effect of the material being neglected.

According to the invention, the cleaning-active material consists of a knitted fabric made of plastic microfibers. Microfiber is a microfiber tangle of 300 to 600, preferably 450 to 550, filaments per fiber, the mean fineness (titer) of the filament being 0.5 to 1 dtex.

Knitted fabrics are made from one or more thread systems by stitching on knitting machines. These machines stabilize the knitted fabric along a cut. In the case of flat knitted fabrics, no seam seams or bias tapes are required to solidify the textile cut of the flat knitted fabric and to avoid fraying the edges. This already reduces the manufacturing effort compared to the manufacturing process of conventional damp wiping covers. at

Damp mop covers with a cover sheet can be easily inserted as an intermediate layer between these two elements without much additional effort when sewing the cover sheet and cleaning-active knitted fabrics.

The knitted fabric which can now be completely optimized for the cleaning effect can now consist entirely of plastic microfibers. This increases the ease of handling, since there is no need for friction-increasing cotton components that would only be necessary for water absorption. This also results in a lower amount of fluff or less fluff discharge compared to flat mop covers with a cotton-containing, cleaning-active side. On the other hand, the knitted fabric made of plastic microfibers is sufficiently thin and permeable to water so that the suction pad arranged on the back can soak up dirty water from the floor through the knitted fabric during the cleaning process. Likewise, after appropriate impregnation with fresh cleaning water, it can release it through the knitted fabric onto the floor surface to be cleaned. Microfibers with a high number of filaments, whose average fineness is low, are particularly suitable. This results in a larger surface, which is why the protective absorption capacity increases. It is also advantageous if the filaments are dexturized, because the individual filaments are held together well.

The absorbency of the absorbent pad can be influenced and varied by selecting a suitable material that forms the absorbent pad.

In an embodiment, the invention provides that the textile fabric consists of the knitted fabric. This has the advantage that a cover sheet is no longer necessary, so that the holder insert pockets and the suction pad can be attached directly to the back of the cleaning-active side facing the floor. This also has the advantage that a second cleaning-active side is now available with the side carrying the suction pad and the holder insertion pockets. This supports the cleaning effect of the damp mop, in particular in areas in which the floor surface to be wiped meets an edge boundary, for example a baseboard or a wall, with the formation of a butt edge.

A further simplification of the production processes can be achieved if the active cleaning side is designed as a knitted, loop-free, shag-free or lamella-free flat knitted fabric. This means or should express that the active cleaning side consists only of the knitted fabric made of plastic microfibers. Since no more that Elements or structures that increase cleaning activity are also not required to be attached to the knitted fabric. In particular, perforation by sewing on the active cleaning side of effective fringes or loops with the knitted fabric and a reduction in tear strength associated therewith is therefore avoided.

It has proven to be particularly advantageous that the knitted fabric consists of polyester fibers or polyester threads, and one possibility is also seen that the knitted fabric consists of a textile fiber made of polyethylene terephthalate, which the invention also provides. Microfibers made of polyester are extremely stable and cleaning-active. They achieve a high cleaning performance with easy sliding behavior. In addition, a knitted fabric made of polyester microfibers or threads is characterized by high rubbing stability, i.e. H. a relatively low abrasiveness. Compared to a flat knitted fabric made of other plastic microfibers, this flat knitted fabric is characterized by a significantly reduced amount of lint, which is again improved compared to conventional fringed mops, or a significantly lower amount of lint released during the wiping process.

The knitted fabric is expediently rectangular, which the invention further provides. This makes it easy to produce a damp mop cover or damp mop matched to the usually rectangular area of mop or damp mop holder.

It is advantageous according to a further development of the invention that the knitted fabric is larger on all sides than the wiper device contact surface defined by the distance between the holder insert pockets and the width of the holder insert pockets. This results in an edge region surrounding the wiper device support surface on all sides. This edge, which protrudes beyond the wiper device support surface and thus the wiper during wiping, replaces the trimmings of the previous damp mop covers Wet mops, but enables the same wiping cleaning close to the edge in the area of abovementioned abutting edges on the edge of the floor wiping surface. This further simplifies or reduces the production process and the manufacturing outlay compared to conventional flat mop covers, since trimmings no longer need to be attached to the mop cover.

It is expedient that the at least one suction pad is formed in the area of the wiper device support surface, which the invention further provides.

A damp mop cover in an embodiment of the invention has a particularly good cleaning performance and ease of handling, in which the absorbent pad is formed from hydrophilic polyester sponge or hydrophilic polyester foam. Hydrophilic polyester sponge or hydrophilic polyester foam is distinguished by the fact that it can be washed at 100 ° C. without deformation, has no noteworthy wash shrinkage and, as a redried sponge or molded foam body, has no change in shape. Also, such a sponge or foam molded article does not lose its color when washed at 100 ° C. and a pH of 10, i. H. the sponge color does not bleed out under such conditions, as the person skilled in the art says.

A hydrophilic polyester sponge or hydrophilic polyester foam which has a water absorption capacity of up to 98% of its volume and / or of up to 1500% of its own weight is very particularly suitable for the configuration of a damp mop cover according to the invention. The combination of a polyester microfiber fabric with such a hydrophilic polyester sponge leads to a particularly good cleaning performance, which is due to the high dirt-carrying capacity of the Polyester microfiber knit and the extremely high water absorption capacity of the polyester sponge is characterized.

A suction pad made of plate-shaped, hydrophilic polyester sponge or polyester foam with a thickness of 5 to 40 mm is particularly easy to process, whereby the invention is characterized in a further embodiment.

Such plates can be processed relatively easily into the suction pad. Here, the invention further provides that the at least one absorbent pad is sewn to the knitted fabric. The sewing of the knitted fabric made of plastic microfiber with the suction pad, especially if it is plate-shaped, represents a simple and inexpensive connection method.

According to a further development of the invention, however, the suction pad can also be arranged in a pocket-shaped or bag-shaped cavity which is surrounded by a plastic material, preferably completely made of polyester, in particular polyester fabric or knitted fabric, preferably made of microfibers. By means of this configuration, a damp mop cover made entirely of plastic, possibly even entirely of polyester, can be created, in which the knitted fabric and the cavity containing the absorbent pad have no significant differences in shrinkage behavior, and furthermore the material forming the absorbent pad in the cavity without restricting its expandability is arranged by fastening seams.

In an expedient embodiment, the invention provides that the cavity has several, in particular two, chambers, which can be arranged parallel to one another and extending in the longitudinal direction of the damp-mop cover. According to a further embodiment of the invention, it is advantageous here if the chambers extend over the length of the mopping device support surface.

In an expedient embodiment, the invention is further characterized in that the suction pad consists of one plate or one plate per chamber. According to a further development of the invention, the plate can be sewn onto the back of the knitted fabric and / or sewn into the cavity. In particular, in order not to make a cover sheet necessary, the wet mop cover in a further embodiment according to the invention is characterized in that the holder insert pockets are sewn to the knitted fabric.

It is also of particular advantage that the holder insert pockets consist of a plastic material, preferably completely made of polyester, in particular polyester fabric or knitted polyester, preferably microfibers, which the invention also provides. In this embodiment, it is now possible to produce the wet mop cover or wet mop entirely from plastic, ie the knitted fabric made of plastic microfiber, holder insert pockets made of plastic material and the absorbent pad made of hydrophilic polyester sponge or foam material, but in particular uniformly made of polyester. Thus, all elements of the damp mop or damp mop cover have no or no noteworthy wash shrink. Such damp mop covers can therefore be produced to fit the holder of the mopping device that is to be provided with them. On the other hand, with the damp wiping or flat wiping covers customary on the market, a wash shrinkage of approx. 4% occurs because they contain cotton components. This shrinkage and the required production tolerance of 1% require a 5% oversize of the damp mop cover during its manufacture. As a result, such covers only reach their correct, exact fit after approximately the fifth wash at 60 ° C with a heavy-duty detergent at a pH of 10. In addition, such a completely made of plastic wet mop cover is characterized by the fact that it shows virtually no lint dispensing, which enables a long period of use or usage beyond the period of use of previous wet mop covers. A damp mop cover made entirely of plastic also offers the best prerequisites for use in cleaning so-called clean rooms, such as those used in the manufacture of electronic components.

A method for producing a damp mop cover with the features according to one of the preceding claims is characterized in that fabric trees made of plastic microfiber fabrics rolled up on a cardboard core are cut to the width required for a mop cover by severing the cardboard core, and the cut roll is endless, preferably automatically by sewing on the suction pads and the holder insert pockets and then separating the desired length ranges to the wet mop cover.

Finally, the invention provides in an embodiment a system which consists of a damp mop cover with the features according to one of claims 1 to 20 and a wiper device with a handle and a wiper plate connected or connectable to the handle via a preferably cardanic joint. tion of the damp mop cover on an underside of the wiper plate and consists of a squeezing device for the mopping device provided with the mopping cloth, the squeezing device having a bearing surface provided with openings and a spaced-apart counter bearing device, so that the mopping plate between the bearing surface and the counter bearing device with a downward insertion movement insertable and by tilting with support on the counter bearing device with its underside which holds the damp mop is pressed against the bearing surface. Such a wiper device and such a squeezing device, which interact in the manner described, are known from WO-A-98/06316 and GB-C-330 543 and from German patent application 100 13 044 by the applicant. In this respect, express reference is made to the disclosure content of these writings. As part of this system, the damp mop cover according to the invention can be conveniently and easily squeezed out and freed from the dirty water absorbed in the suction pad.

The invention is explained below by way of example with reference to the drawing. This shows in

1 shows a first exemplary embodiment of a damp mop according to the invention and in

Fig. 2 shows a second embodiment of a damp mop cover according to the invention.

The terms wet mop cover and wet mop and possibly flat mop cover are used as synonyms in the context of the present description. The damp mop cover 1 consists of a textile fabric 2, which as a knitted fabric 3 consists of plastic microfibers, in the present case of polyester fibers or polyester threads. The microfiber knitted fabric consists of 508 individual filaments, each filament having an average fineness of 0.6 dtex. The knitted fabric 3 can be made of a textile fiber made of polyethylene terephthalate. In the damp mop cover shown, the textile fabric 2 consists of the knitted fabric 3, so that the damp mop cover has two cleaning-active sides, the bottom-facing cleaning-active side 4 as the underside and the side 5 facing away from the floor as the top. Alternatively, the top of the damp mop cover could also be made of a textile fabric trained cover sheet, preferably made of plastic material, in particular polyester. In this case, the cover sheet would be sewn to the knitted fabric 3. On the back to the active cleaning side 4, ie on the top 5 two holder insertion pockets 6 and 7 are sewn onto the knitted fabric 3.

Between the two holder insertion pockets 6 and 7, a suction pad 8 is applied to the top 5 of the knitted fabric 3. The suction pad 8 is preferably sewn onto the top 5 of the knitted fabric 3. The suction pad 8 is made of plastic material. This is a hydrophilic polyester sponge or a hydrophilic polyester foam. The polyester sponge or foam has a water absorption capacity of up to 98% of its volume and / or up to 1500% of its own weight. Furthermore, the hydrophilic polyester sponge or foam is characterized by a bulk density according to DIN EN ISO 845 of 58.0 +/- 3.0 kg / m ³ , a compression hardness, CV40 according to DIN EN ISO 3386-1 of 5.0 +/- 0.8 kPa, a tensile strength according to DIN 53571 of at least 100 kPa, an elongation at break according to DIN 53571 of at least 200% and a compression set, 50%, according to DIN EN ISO 1856 of a maximum of 5.0%. The hydrophilic polyester foam is easy to punch and has a hydrophilicity of at most 60 seconds in a sink test in water, ie the material absorbs water and sinks in water from a floating position within 60 seconds. This hydrophilic polyester sponge foam material does not deform even at washing temperatures of 100 ° C and does not lose its color at this temperature and a pH of 10. Furthermore, this sponge material is characterized by the fact that it does not show any noteworthy wash shrinkage and after it has dried as a sponge that has dried again, it does not show any changes in shape. The suction pad 8 consists of plate-shaped hydrophilic polyester sponge or polyester foam in the form of a rectangular plate 9 with a thickness of 5 to 40 mm. The plate 9 is on the bottom 4 for active cleaning back side, the top 5, sewn on. The seams are not shown in FIG. 1. The cleaning-active side 4 of the knitted fabric 3 is, apart from the loops formed by the stitches of the knitted fabric, formed as a fringe-free, loop-free, shag-free or lamella-free fabric. Overall, the surface knitted fabric 3 is rectangular, it has edge lengths that cause the surface knitted fabric 3 to be larger on all sides than the wiper device support surface defined by the spacing of the holder insert pockets 6, 7 from one another and the width of the individual holder insert pockets 6, 7. In the exemplary embodiment according to FIG. 1, this wiper device support surface is covered by the rectangular plate made of hydrophilic polyester sponge. In the application, the holder surface of a mopping device is inserted into the pockets 6 and 7, so that the underside of the mopping device holder rests on the rectangular plate 9 in the inserted position. In this position, the damp mop cover 1 is then guided over a floor surface for cleaning. Here, the suction pad 8 absorbs moisture from below through the active cleaning side 4 on the floor surface. Dirt is absorbed by the textile fabric made of polyester microfiber. For cleaning or dispensing the dirty water taken up, the damp mop cover is fed to a press together with the mopping device holder and the dirty water is pressed out by compressing the suction pad 8. Here, the press preferably has a support surface and a counter bearing device, as will be explained in more detail below. The damp mop cover can then be fed into a container with fresh cleaning water. The suction pad then sucks up the fresh cleaning water. If the damp mop cover is now guided over the floor surface with the holder, a slight pressure from above onto the holder plate of the device is sufficient to compress the suction pad 8 and to deliver cleaning fluid to the floor surface to be wiped. After the liquid has been dispensed, the damp mop cover can then be guided over the moistened surface and, as explained above, moisture and dirt can be removed from the surface. FIG. 2 shows an alternative exemplary embodiment, components identical to the exemplary embodiment according to FIG. 1 being provided with the same reference symbols. The difference from the embodiment of FIG. 1 is that the suction pad 8 is formed in a cavity 10 which consists of two pocket-shaped or bag-shaped chambers 11, 12. The cavity 10 can also consist of only one chamber. The two chambers 11, 12 are arranged parallel to one another and extend in the longitudinal direction of the damp mop cover 1 over the length of the mop surface. A plate made of the hydrophilic polyester sponge or polyester foam material is arranged in the cavity 10 or the respective chambers 11, 12. These are preferably sewn into the cavity 10 or the respective chamber 11, 12. Of course, it is also possible to arrange more than one plate in the cavity 10 or in the respective chamber 11 or 12. The cavity 10 is formed on the one hand by the top 5 of the knitted fabric 3 and on the other hand by forming an envelope to form a cavity on this top, in particular formed on this sewn plastic material. This plastic material enveloping the cavity 10 is preferably material that consists entirely of polyester, in particular it is a polyester fabric or knitted polyester fabric. A polyester knitted fabric made of microfibers is also preferred.

In the context of the present invention, knitted fabric is understood to mean a flat structure which is produced from one or more thread systems by stitch formation on knitting machines. This includes both the processing of a cross thread system in the so-called knitting operation and the processing of a longitudinal thread system, which can optionally be supplemented by a cross thread system, in the so-called warp knitting. The holder insert pockets 6, 7 sewn onto the top side 5 of the knitted fabric 3 consist of a plastic material which preferably also consists entirely of polyester, in particular polyester fabric or knitted polyester, preferably microfibers.

Of course, it is also possible for the suction pad 8, in contrast to that shown in FIGS. 1 and 2, to extend beyond the wiper device support surface on the upper side 5 of the damp mop cover 1.

For the production of a damp mop cover 1, it has proven to be expedient to first cut the web-shaped plastic microfiber knitted fabric supplied as a roll onto a cardboard core by dividing the roll to the width required for a mop cover. In this case, a slice corresponding to the width of the mop cover 1 to be produced is separated from the fabric roll by severing the cardboard core. This separated disk or roll is then unrolled endlessly and provided in sections in a production line with the suction pad 8 or additionally with the pocket or bag-shaped chambers 11, 12 or a cavity 10 and the opposite holder insertion pockets 6, 7. The individual wet mop cover sections thus formed are then separated from the endless belt, so that the individual mop covers result. Depending on the processing and production line, the width of the pane separated from the original roll corresponds to either the width of the finished mop cover or the longitudinal extent of the finished mop cover.

The wet mop cover according to the invention is used in a system consisting of the wet mop cover and a wiper device with a handle and a wiper plate connected or connectable to the handle via a preferably cardanic joint for holding the wet mop cover on the underside of the mop plate and from one Squeezing device for the wiping device provided with the damp mop cover. The squeezing device has a bearing surface provided with openings and a counter-bearing device arranged at a distance from it, so that the wiper plate between the bearing surface and the counter-bearing device can be inserted with a downward insertion movement. By tilting with support on the counter bearing device, the wiper plate with its underside holding the damp mop cover can be pressed against the bearing surface, so that wiping water contained in the suction pad 8 or the damp mop cover is pressed out. Such a squeezing device and a corresponding wiping device are known to the person skilled in the art. For example, these are known or described in WO-A-98/06316 and GB-C-330 543 and German patent application 100 13 044.
