context_page_description: A mop is a mass or bundle of coarse strings or yarn, etc., or a piece of cloth, sponge or other absorbent material, attached to a pole or stick. It is used to soak up liquid, for cleaning floors and other surfaces, to mop up dust, or for other cleaning purposes. The word is attested in English as early as 1496, but new refinements and variations of mop designs have been introduced, from time to time. For example, American inventor Jacob Howe received U.S. patent #241 for a mop holder in 1837 and Thomas W. Stewart in 1893. At the 1968 Miss America protest, protestors symbolically threw a number of feminine products into a "Freedom Trash Can", which included mops.
context_section_description: Professional flat mops are made for pre-moisting. Mops are pre-impregnated with an ideal amount of water mixed with an appropriate amount of detergent. This means that the cleaner does not need to bring any additional water on the cleaning trolley. This ideal amount is often recommended by the manufacturer in terms of weight percent of water per weight of the dry mop, for example "175% water per weight of the dry mop".
  Mops for pre-moisting are flat sheets of (often microfiber) textile, usually about 15 cm (6 in) wide, and comes in variable lengths (usually 30–100 cm (12–39 in)). Mops for pre-moisting are fastened on a handle with a flat pad mount with the aid of velcro or a pouch on the mop, in which the pad on the handle fits.
  Pre-moisting can be done with a special washing machine or by hand by simply folding and packing the mops tight in a container and pouring the measured amount of water over them. The mops will then need about 5–10 minutes for the liquid to distribute evenly in their tissue before use. This offers some advantages:
  The cleaner does not have to have a bucket of water with him/her when sweeping the floor, but simply carries an appropriate number of mops. This means the weight of the equipment can often be kept lower.
  The risk of over-wetting the floor and leave puddles is eliminated if the wetness is ideal.
