Past Performance
Sioux Corporation has been manufacturing steam cleaning and pressure washing systems since 1939. All machines are tracked by serial number so if repairs are necessary, we can provide an exact replacement part or like performing component. This ensures longer equipment life, and consistent performance throughout the life of the machine. Sioux’s standard line of steam cleaners, hot water pressure washers, and combination pressure washer/steam cleaners are third-party certified to UL 1776 and CAN CSA-BSA140.11-M89. Sioux also offers a full line of explosion-proof models that are certified to UL 1203 and CAN CSA C22.2 No 68-92. We have provided equipment to the United States Government since 1939. Our systems have been used in the Department of Defense in every war and conflict starting with WWII.
