For over eight decades, Sioux Corporation has manufactured and supplied industrial cleaning and heating equipment to federal, state, and municipal agencies across the United States. Every unit is engineered, assembled, and tested at our facility in Beresford, South Dakota.
Sioux Corporation was founded in 1939 with a single product: a steam cleaner designed for automobile engines. Since then, we have grown into one of the country's most recognized manufacturers of industrial pressure washers, steam cleaners, water heaters, and steam generators. Our cleaning equipment for military installations operates on every continent and across a wide range of demanding environments.
A Legacy Built on Reliability
As a government industrial equipment supplier, Sioux has worked with agencies at every level, from small municipal public works departments to branches of the U.S. Department of Defense. Our engineering team holds over 50 patents, and our sales staff includes specialists who understand public-sector procurement requirements and the applications that matter most to government buyers.

Sioux manufactures a complete line of pressure washers and cleaning equipment for government facilities, military bases, and public infrastructure. Units are available in fuel-fired, all-electric, and explosion-proof configurations. Machines can be mounted on a self-contained trailer with an included water tank for operations in remote or field locations.
