1. A laundry device including: i) a flexible waterproof housing for housing a textile item, water and cleaning material;ii) an opening in the housing for inserting or removing the textile item; andiii) a seal for sealing the opening;iv) a flexible base secured to the housing, wherein the base covers an aperture in the housing, and the base having a thickness that is greater than a thickness of the housing;v) a frictional washing surface incorporated on the base forming a portion of an inner surface of the housing; andwherein a textile item is pressed and rubbed against the frictional washing surface to effect cleaning by gripping or pressing on an outer surface of the housing. 2. The laundry device of claim 1, wherein the frictional washing surface makes up less than 50%, less than 40% or less than 30% of the total inner surface of the housing. 3. The laundry device of claim 1, wherein the frictional washing surface includes projections and/or depressions provided on the base which is attached to the housing. 4. The laundry device of claim 3, wherein the base includes one or more flex lines to increase the flexibility of the frictional washing surface. 5. The laundry device of claim 1, wherein the seal includes a waterproof zipper, a fold-over seal, a roll down seal, a zip-lock or a clamping seal. 6. The laundry device of claim 1, wherein the housing includes a valve for releasing air. 7. The laundry device of claim 1, wherein the housing includes a gripping surface on the outer surface of the housing backing at least part of the base to restrict movement of the frictional washing surface relative to a surface the laundry device is placed on. 8. The laundry device of claim 7, wherein the gripping surface includes an elastomeric polymer layer, an elastomeric polymer coat, or elastomeric polymer projections. 9. The laundry device of claim 7, wherein the housing includes a gripping portion backing the base and a non-gripping portion on the outer surface of the housing opposite the frictional washing surface, wherein the gripping portion has a coefficient of friction greater than a coefficient of friction of the non-gripping portion. 10. The laundry device of claim 1, wherein the waterproof housing includes an outlet for removing fluid from the waterproof housing while retaining textiles in the waterproof housing. 11. The laundry device of claim 1, wherein the waterproof housing is invertible. 12. The laundry device of claim 1, wherein the waterproof housing has a volume between 2 L and 40 L. 13. The laundry device of claim 1, wherein the waterproof housing includes an optimal water level marking, which indicates a level between 10% and 65% of the capacity of the housing when sealed. 14. The laundry device of claim 1, wherein the waterproof housing includes a transparent or translucent portion to allow visualisation of the contents of the laundry device. 15. A method of producing the laundry device of claim 1, the method comprising attaching or applying the frictional washing surface to the inner surface of the flexible waterproof housing during production of the housing or after production of the housing or by attaching the frictional washing surface to cover the aperture in the flexible waterproof housing. 16. The method of claim 15, wherein the method further includes attaching or applying a gripping surface to the outer surface of the housing that backs the frictional washing surface. 17. The laundry device of claim 1, wherein the housing includes a fabric with microdenier fibres or fibres, filaments, threads or yarns with a denier between 0.5 and 600, the fabric, fibres, filaments, threads or yarns coated or impregnated with a polymer. 18. The laundry device of claim 17, wherein the fibre, filament, thread or yarn has a denier between 1 and 300, or between 25 and 220. 19. The laundry device of claim 17, wherein the fibres, filament, thread or yarn include nylon fibres, polyester fibres, ultra high molecular weight polyethylene fibres, liquid crystal polymer fibres, aramid fibres, carbon fibres, phenol-formaldehydes, polyvinyl alcohol fibres (PVA), polyvinyl chloride fibres, polyolefin fibres, PBO Zylon fibres, PEN fibers, poly-urethane fibres, rayon fibres, cotton fibres, silk fibres, wool fibres, linen fibres, hemp fibres, coir fibres, or jute fibres. 20. The laundry device of claim 17, wherein the polymer includes a urethane, a silicone, a PVC, a PVC substitute, a vinyl, an acrylic, a polytetrafluoroethylene, a polyester, a polyamide, a polyimide, a para-aramid, a flouroplymer, a DWR or a latex coating. 21. The laundry device of claim 17, wherein the fabric is a ripstop fabric, a Cordura® fabric, a Kodra® fabric, an Oxford weave fabric, a Taffeta fabric, a CTF3® fabric or a Cuban fabric. 22. The laundry device of claim 1, wherein the base includes the frictional washing surface on a top surface and a gripping surface on a bottom surface and the base attached to the housing to cover the aperture in the housing thereby allowing the frictional washing surface to be on the inside of the device and the gripping surface to be on the outside of the housing and backing the frictional washing surface. 23. The laundry device of claim 1, wherein the housing has a tubular shape and the frictional washing surface is provided on a side wall of the tubular housing with a gripping surface backing the frictional washing surface. 24. The laundry device of claim 1, wherein the housing includes an outlet with a surface area less than 10 cm2 for releasing air, the outlet including a valve or a cap to control airflow through the outlet.
