NorthStar Hot Water Pressure Washer w/ Wet Steam – Commercial Grade Cleaning Power

This NorthStar hot water pressure washer with wet steam is built for the toughest cleaning jobs where cold water units fall short. Loaded with advanced technology, it delivers an unbeatable combination of high heat, high impact pressure, and high flow rate to melt through grease, oil, manure, and heavy grime fast.

Featuring a 250°F wet steam mode and an industry-leading 150°F temperature rise, this unit dramatically improves cleaning efficiency while reducing chemical use. The digital thermostat provides precise temperature control—maintaining a stable 15–18°F range—so you get consistent hot water without the temperature swings common in other brands.

Power comes from a Honda GX390 engine with electric start, paired with a CAT Pumps direct-drive pump for quiet, reliable performance. A fuel-efficient downdraft burner and large 8-gallon fuel tanks extend run time, letting you work longer with fewer refueling stops.
