Commercial use of washing machines
A commercial washing machine is intended for more frequent use than a consumer washing machine. Durability and functionality is more important than style; most commercial washers are bulky and heavy, often with more expensive stainless steel construction to minimize corrosion in a constantly moist environment. They are built with large easy-to-open service covers, and washers are designed not to require access to the underside for service. Often commercial washers are installed in long rows with a wide access passageway behind all the machines to allow maintenance without moving the heavy machines.

Many commercial washers are built for use by the general public, and are installed in publicly accessible laundromats or laundrettes, operated by money accepting devices or card readers. The features of a commercial laundromat washer are more limited than a consumer washer, usually offering just two or three basic wash programs and an option to choose wash cycle temperatures.
The common front-loading commercial washing machine also differs from consumer models in its expulsion of wash and rinse water. While the consumer models pump used washer water out, allowing the waste line to be located above the washer, front loading commercial machines generally use only gravity to expel used water. A drain in the rear, at the bottom of the machine opens at the appointed time during the cycle and water flows out. This creates the need for a drainage trough behind machines, which leads to a filter and drain. The trough is usually part of a cement platform built for the purpose of raising the machines to a convenient height, and can be seen behind washers at most laundromats.

By contrast, commercial washers for internal business operations (still often referred to as "washer/extractor" machines) may include features absent from domestic machines. Many commercial washers offer an option for automatic injection of five or more different chemical types, so that the operator does not have to deal with constantly measuring out soap products and fabric softeners for each load by hand. Instead, a precise metering system draws the detergents and wash additives directly from large liquid-chemical storage barrels and injects them as needed into the various wash and rinse cycles. Some computer-controlled commercial washers offer the operator control over the various wash and rinse cycles, allowing the operator to program custom washing cycles.
Most large-scale industrial washers are horizontal-axis machines, but may have front-, side-, or top-load doors. Some industrial clothes washers can batch-process up to 800 pounds (360 kg) of textiles at once, and can be used for extremely machine-abusive washing tasks such as stone washing or fabric bleaching and dyeing.
An industrial washer can be mounted on heavy-duty shock absorbers and attached to a concrete floor, so that it can extract water from even the most severely out-of-balance and heavy wash loads. Noise and vibration is not as unacceptable as in a domestic machine. It may be mounted on hydraulic cylinders, permitting the entire washer to be lifted and tilted so that fabrics can be automatically dumped from the wash drum onto a conveyor belt once the cycle is complete.
One special type of continuous-processing washer is known as the tunnel washer. This specialized high-capacity machine does not have a drum where everything being washed undergoes distinct wash and rinse cycles, but moves the laundry slowly and continuously through a long, large-diameter horizontal-axis rotating tube in the manner of an assembly line, with different processes at different positions.

Social impact of washing machines.
The historically laborious process of washing clothes (a task which often had a whole day set aside to perform) has at times been labelled 'woman's work'. The spread of the washing machine has been seen to be a force behind the improvement of women's position in society. In 2009 the Italian newspaper L'Osservatore Romano published a Playboy article on International Women's Day arguing that the washing machine had done more for the liberation of women than the contraceptive pill and abortion rights. A study from Université de Montréal, Canada presented a similar point of view, adding fridges as well.The following year, Swedish statistician Hans Rosling suggested that the positive effect the washing machine had on the liberation of women, makes it "the greatest invention of the industrial revolution". It has been argued that washing machines are an example of labour saving technology, which does not decrease employment because households can internalize the gains of the innovation. Historian Frances Finnegan credits the rise of this technology in helping undercut the economic viability of the Magdalene Asylums in Ireland, later revealed to be inhumanly abusive prisons for women, by supplanting their laundry businesses and prompting the eventual closure of the institutions as a whole.
Before the advent of the washing machine, laundry was done first at watercourses and then in public washhouses known as lavoirs. Camille Paglia and others argue that the washing machine led to a type of social isolation of women, as a communal activity became a solitary one.
In India, dhobis, a caste group specialized in washing clothes, are slowly adapting to modern technology, but even with access to washing machines, many still handwash garments as well. Since most modern homes are equipped with a washing machine, many Indians have dispensed with the services of the dhobiwallahs.
Environmental impact of washing machine
Due to the increasing cost of repairs relative to the price of a washing machine, there has been a major increase in the number of defective washing machines being discarded, to the detriment of the environment. The cost of repair and the expected life of the machine may make the purchase of a new machine seem like the better option.
Different washing machine models vary widely in their use of water, detergent, and energy. The energy required for heating is large compared to that used by lighting, electric motors, and electronic devices. Because of their use of hot water, washing machines are among the largest consumers of energy in a typical modern home.
