Pressure Washers


Pressure Washers - Sioux Corporation

Sioux has over 500 standard models available with a wide range of accessories and options. In addition, Sioux is the industry leader in custom engineering to provide the exact equipment for your specific application. It is well-known for manufacturing the longest lasting machines in the industry.

In mining, Sioux's pressure washers are used to clean underground mining equipment by blasting off grease, oil and grime off Cats, crawlers, loaders, bolters, graders, and other equipment. Sioux cleaners are also available as self-contained units with an integrated pressure washer/steam cleaner, water tank, gasoline or diesel engine and mounted on a heavy-duty over the road trailer. These custom machines are great for cleaning at remote locations where water, fuel or electrical sources are not available which is especially common in surface mining conditions.
