Speedy, efficient housekeeping is a requirement for busy hotels and resorts. The main distinction between housekeeping and cleaning is that cleaning services focus on just that: improving an area's cleanliness, whereas housekeeping also includes tidying up and making a space look inviting and 'on brand'.

Industrial cleaning services are specialized cleaning services for areas in industrial facilities, such as factories and manufacturing facilities, self-storage buildings, warehouses and power plants.

Janitorial services are a type of commercial cleaning that handles various tasks in professional corporate settings. This includes financial institutions, medical facilities, factory offices, and the like. Your service providers are referred to as janitors, cleaners, or custodians.

The largest janitorial company in the US is ABM Industries, with a revenue of $7.8 billion and 140,000 employees. As of 2022, the US janitorial service industry has a market size of $97.6 billion.
