CROSS REFERENCE TO RELATED APPLICATION [0001] This application claims the benefit of U.S. Provisional Application No. 60/737822, filed on Nov. 17, 2005. FIELD OF THE INVENTION [0002] The present invention relates to the use and application of a zwitterionic polymer of defined structure. More specifically it relates to the application of said polymer in a composition, said composition being preferably suitable for cleaning operations, such as the cleaning of floors, work surfaces, appliances, furniture, carpet and upholstery. BACKGROUND OF THE INETION [0003] Manufacturers of cleaning products are continuously searching for new components that will improve the effectiveness of the composition, the device that delivers the composition or both. The present invention relates to a new ingredient for use in cleaning of surfaces such as floors, tiles, work surfaces, car interior plastics and leathers, ceramic surfaces, windows, blinds, shades, mirrors, household appliances, furniture, upholstery etc. In general terms, compositions for cleaning surfaces are effective at releasing the soil from the surface, suspending or solubilising the soil. However if the suspended or solubilised soil is not picked up in some way, then the soil remains on the surface and will be visible on the surface once the composition evaporates. The Applicants having investigated this problem have developed a new composition comprising a component that agglomerates soils, especially inorganic soils and soils comprising particulates such as soot, clay, dust, hair, toothpaste, mixtures of oils and dust, and the like. These soils are typically found in homes and businesses as well as in motorized vehicles. A soil agglomerate is larger than a non-agglomerated soil and is therefore easier to remove from the surface. Soil agglomerate removal is aided by using a disposable cleaning substrate chosen to bind the agglomerating agent. SUMMARY OF THE INVENTION [0004] According to the present invention there is provided a new use of a water-soluble or water-dispersible copolymer I as an agglomerating agent in a cleaning operation, said polymer comprising: [0005] at least a monomer compound of general formula i: in which [0006] R.sub.1 is a hydrogen atom, a methyl or ethyl group; [0007] R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6, which are identical or different, are linear or branched C.sub.1-C.sub.6, alkyl, hydroxyalkyl or aminoalkyl groups; [0008] m is an integer from 0 to 10; [0009] n is an integer from 1 to 6; [0010] Z represents a --C(O)O-- or --C(O)NH-- group or an oxygen atom; [0011] A represents a (CH.sub.2).sub.p group, p being an integer from 1 to 6; [0012] B represents a linear or branched C.sub.2-C.sub.12, polymethylene chain optionally interrupted by one or more heteroatoms or heterogroups, and optionally substituted by one or more hydroxyl or amino groups; [0013] X, which are identical or different, represent counterions; and [0014] (b) at least one hydrophilic monomer carrying a functional acidic group which is copolymerizable with (a) and which is capable of being ionized in the application medium; [0015] (c) optionally at least one monomer compound with ethylenic unsaturation with a neutral charge which is copolymerizable with (a) and (b), preferably a hydrophilic monomer compound with ethylenic unsaturation with a neutral charge, carrying one or more hydrophilic groups, which is copolymerizable with (a) and (b).

DETAILED DESCRIPTION OF THE INVENTION [0049] Definitions: All ratios and percentages are on a weight basis unless otherwise specified. [0050] By `aqueous` composition, it is meant water and solvents that have a 5% or more water solubility on a weight basis. Non-limiting examples of aqueous chemicals include deionized water, distilled water, city water, ethanol, 2-propanol, glycerine and propylene glycol n-butyl ether. By `ready-to-use composition`, it is meant composition concentrations that used by the consumer for actual cleaning purposes. The `ready to use` concentration is often the same as the composition concentration supplied by the manufacturer. In some instances, manufacturers will supply a composition as a concentrate and direct the consumer to dilute the composition via usage instructions; in those instances, the ready-to-use composition means the concentration of the diluted product. Unless otherwise specified all concentrations herein below are supplied on a ready-to-use basis. [0051] By `wipe` it is meant a nonwoven of convenient size for use by the consumer. By `convenient size` it is meant x-y dimensions that allow the consumer to use the wipe/pad by hand or to fit the wipe/pad onto a typical cleaning implement as available commercially or described in the art. Non-limiting examples of convenient wipe and pad sizes include 16 cm.times.27 cm, 17 cm.times.20 cm, 10 cm.times.30 cm, 20 cm.times.30 cm, 15 cm.times.36 cm, 20 cm.times.40 cm, and the like. A `pad` consists of a laminate of wipes. Laminates comprise two or more nonwoven substrates that are bound, fused, glued, conformed or heat sealed together for the purpose of creating a single structure to be used by the consumer. The wipe or pad can be dry, dry to the touch or premoistened. [0052] As used herein, the terms `nonwoven`, `substrate` and `nonwoven substrate` are used interchangeably. Nonwoven substrates are absorbent and preferably disposable. By `absorbent` it is meant that the nonwoven can absorb at least one gram of de-ionized water per gram of dry nonwoven substrate. By `disposable` it is meant that the nonwoven is typically used for a single cleaning job and then disposed of. In some cases, the disposable substrate has limited reusability in that it can be used, stored and re-used. As such the amount of re-use is limited and is typically determined by the ability of the substrate to continue to absorb more liquid and/or soil. Unlike sponges, cloths, chamois and other conventional cleaning implements, the disposable substrate, once used, can not be easily reversed to its original state by the consumer. [0053] By `synthetic material` or `synthetic fibers`, it is meant herein a hydrophobic material based on polymeric organic polymers. The synthetic material herein is selected from the group consisting of polyethylene, polypropylene, polyester, copolyesters, and mixtures and derivatives thereof. Other synthetic materials include polyvinyl acetate, polyethylvinyl acetate, polyvinyl chloride, polyvinylidene chloride, polyacrylics, polyamides, copolyamides, polystyrenes, polyurethanes and copolymers of any of the foregoing such as vinyl chloride/vinyl acetate. As used herein, the terms `thermoplastic` materials are synthetic materials that can be melted at temperatures between 75.degree. C. and 175.degree. C. [0054] As used herein, `non-synthetic material or `non-synthetic fibers`, refers to materials or fibers that are based on naturally occurring materials and are either synthetically modified or unmodified. [0055] Examples of suitable unmodified/modified naturally occurring fibers include cotton, Esparto grass, bagasse, hemp, flax, silk, wool, wood pulp, chemically modified wood pulp, jute, ethyl cellulose, and cellulose acetate. Non-synthetic materials and fibers used herein are preferably based on treated or untreated cellulose, especially wood pulp and synthetic cellulose derivatives including Rayon.RTM. and Lyocell.RTM.. [0056] By `superabsorbent material`, it is meant any material lodged inside or on an absorbent disposable substrate, that effectively traps and locks water and water-based solutions, effectively removing water or water-based solutions from the floor. A "superabsorbent material" is any absorbent material having a g/g capacity for deionized water of at least about 15 g/g, when measured under a confining pressure of 0.3 psi. Superabsorbent materials are typically high molecular weight polycarboxylate polymers that can gel upon acquisition of large amounts of aqueous composition, especially aqueous compositions that are predominantly water. Water-Soluble or Water-dispersible Copolymer I [0057] The water-soluble or water-dispersible agglomerating copolymer I of the present invention comprises, in the form of polymerized units: [0058] a) at least a monomer compound of general formula i: in which [0059] R.sub.1 is a hydrogen atom, a methyl or ethyl group; [0060] R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6, which are identical or different, are linear or branched C.sub.1-C.sub.6, alkyl, hydroxyalkyl or aminoalkyl groups; [0061] m is an integer from 0 to 10; [0062] n is an integer from 1 to 6; [0063] Z represents a --C(O)O-- or --C(O)NH-- group or an oxygen atom; [0064] A represents a (CH.sub.2)p group, p being an integer from 1 to 6; [0065] B represents a linear or branched C.sub.2-C.sub.12, polymethylene chain optionally interrupted by one or more heteroatoms or heterogroups, and optionally substituted by one or more hydroxyl or amino groups; [0066] X, which are identical or different, represent counterions; and [0067] (b) at least one hydrophilic monomer carrying a functional acidic group which is copolymerizable with (a) and which is capable of being ionized in the application medium; [0068] (c) optionally at least one monomer compound with ethylenic unsaturation with a neutral charge which is copolymerizable with (a) and (b), preferably a hydrophilic monomer compound with ethylenic unsaturation with a neutral charge, carrying one or more hydrophilic groups, which is copolymerizable with (a) and (b). [0069] The monomer (a) can be prepared, for example, according to the reaction schemes shown in U.S. Pat. No. 6,569,261 to Rhodia, column 2, line 40 to column 3, line 45 which is incorporated herein by reference. [0070] The resulting copolymer I has a molecular mass of at least 1000, advantageously of at least 10,000; it can range up to 20,000,000, advantageously up to 10,000,000. Except when otherwise indicated, when the term molecular mass is used, it will refer to the weight-average molecular mass, expressed in g/mol. The latter can be determined by aqueous gel permeation chromatography (GPC) or measurement of the intrinsic viscosity in a 1N NaNO.sub.3 solution at 30.degree. C. The copolymer is preferably a random copolymer. [0071] Preferably, in the general formula (i) of the monomer (a), Z represents C(O)O, C(O)NH or 0, very preferably C(O)NH; n is equal to 2 or 3, very particularly 3; m ranges from 0 to 2 and is preferably equal to 0 or 1, very particularly to 0; B represents --CH.sub.2--CH(OH)--CH.sub.2).sub.q, with q from 1 to 4, preferably equal to 1; R.sub.1 to R.sub.6, which are identical or different, represent a methyl or ethyl group.
