A self-service laundry business is a type of business that operates a facility equipped with commercial-grade washers and dryers. Customers bring their dirty laundry to the self-service laundry and pay a fee to use the machines. They can select the appropriate washer and dryer settings, add detergent or other laundry products, and operate the machines themselves. The business may provide additional services such as vending machines for detergent and snacks, seating areas, and folding tables.
