A mop is a textile mounted on a handle used in cleaning. It is generally used for cleaning floors.
The inventor Eddy Key received a patent for a mop holder in 1837.
In daily speech a mop is used in reference to a yarn mop. The mop (eye) consists of thick lengths of yarn (about 25 cm) or, in newer models, soft strands of water-absorbing fabric or Wettex. A yarn mop is usually mounted on a long (about 1.5 m) handle with a thread end on which the mop can be fastened by turning it clockwise.
To clean a floor, the mop is soaked in a bucket of water, usually mixed with a cleaning solution and swept against the surface. Some buckets include a wringer to strain excess water from the mop, so as not to saturate the floor and as not to leave excessive water on the floor. Leaving too much (contaminated) water on the floor will usually result in dust collection and thus result in a less clean floor.
Yarn mops are also often used to clean up liquid spills.
A dry-mop or dust-mop is designed to pick up dry, loose contamination like dust, earth and sand from the surface. It consists of yarn and/or microfiber and is used as a first step in cleaning a floor.
Professional dry mops consists of a flat sheet of micro fiber textile or sheets with a surface of looped yarn, usually about 15 cm wide, and comes in variable lengths (usually 30 - 100 cm).
The dry-mop can in many instances replace a broom and has the ability to hold a limited amount of dust or sand within itself. Ideally, it should be machine washed when it becomes saturated with dust. Another option is using a vacuum cleaner to suck surface dust away from the mop, however this is limited in its effectiveness.
Single-use dry-mops are available.
Professional wet-mops consists of a flat sheet of microfiber textile or sheets with a surface of looped yarn (which might contain microfiber as well), usually about 15 cm wide, and comes in variable lengths (usually 30 - 100 cm).
Professional flat mops are made for pre-moisting. Mops are pre-impregnated with an ideal amount of water mixed with an appropriate amount 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 wide, and comes in variable lengths (usually 30 - 100 cm). Mops for pre-moisting is fastening 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.
Advantages with pre-moisting are among other:
A mop handle consists of a long piece of wood or aluminium tubing fitted with some kind of mount for the mop. The handle can be made for mounting a mop on it by means of:
