Hotsy Cleaning Systems, Inc. carries many hot water pressure washer models in a variety of formats. Why choose a hot water pressure washer? Because cleaning with hot water is often quicker and in some cases, more thorough, depending on what you’re cleaning. For instance, if you’re cleaning oily-based residues, a hot water power washer will cut through and penetrate grime at the molecular level, instead just pushing it around like a cold water machine does.

Hot Pressure Washers Reach High Temperatures
For industries like food processing that worry with sanitation requirements, sanitizing cleaning equipment such as a hot water power washer provides a defense against germs and bacteria. By the time the water rushes out of the heating coil and through the wand, it will have reached temperatures of up to 200°F. Combine this hot water with our specially formulated detergents, and you have an outstanding cleaning weapon, delivering a one-two punch.

Hotsy hot pressure washers use either electric or gasoline to run the high-pressure pump and a secondary fuel source to fire the burner. The choice between electric or gasoline-powered hot water pressure washers is typically dependent on where you’ll be cleaning. Next pick a fuel source for the burner - Hotsy hot water washers are heated with fuel oil, diesel, natural gas, propane, or electric. The final choice depends on whether or not you need portability.

We have locations in Madison, La Crosse, Eau Claire, Wausau, Green Bay as well as our main location in Delafield. Call toll-free (800) 242-2353.
