All eight models of the Hotsy 1200 Series self-contained, gas-powered hot-water pressure washers use diesel (or fuel oil) to heat water and produce cleaning power ranging from 3,000 to 4,000 psi of water pressure and 4.3 to 5.6 gpm of flow volume. The models come standard with the Hotsy belt-drive high-pressure pump that comes with a seven-year warranty. Four models feature a 2,000-watt generator. They are designed to be installed on a trailer or pickup bed to work in conjunction with a water tank for added portability. For more information visit www.hotsy.com or call (8000 525 1976.
