Professional flat mops are made for pre-moistening. 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 percentage of water per weight of the dry mop, for example "175% water per weight of the dry mop".

Mops for pre-moistening are flat sheets of (often microfiber) textile, usually about {{Convert |15|cm|0|abbr = on}} wide, and come in variable lengths (usually {{Convert|30|-|100|cm|0|abbr = on}}). Mops for pre-moistening 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-moistening 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 bring a heavy [[bucket]] of water when mopping 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 leaving puddles is reduced.
