- Mar 26
- 2 min read
Choosing between a cold water and hot water pressure washer is one of the biggest equipment decisions contractors face. Both types deliver cleaning power, but the right choice depends on the jobs you handle, the surfaces you clean, and how much grime, grease, and buildup you encounter.
Below is a contractor‑focused comparison, along with top pressure washer picks you.

Cold Water Pressure Washers (Best for General Contractors)
Cold water units are the most common among contractors because they are affordable, powerful, and versatile. They rely on high PSI to blast away dirt, mud, mildew, and surface debris.
Best Uses
House washing
Concrete cleaning
Decks and fences
Vehicle washing
Driveways and sidewalks
General contractor cleaning
Recommended Cold Water Units
1. Simpson PowerShot 4400 PSI Contractor‑grade Honda engine, welded steel frame, and high PSI make this a staple for heavy‑duty daily use.
2. Westinghouse WPX3400 Gas Pressure Washer: A strong, budget‑friendly model with excellent reviews and reliable performance for general cleaning.
Hot Water Pressure Washers (Best for Grease & Commercial Cleaning)
Hot water units use a burner system to heat water up to 200–250°F, allowing them to cut through grease, oil, and industrial residue far faster than cold water models.
Best Uses
Restaurants and commercial kitchens
Equipment and machinery cleaning
Oil‑stained concrete
Industrial facilities
Fleet washing
Stubborn grime removal
Recommended Hot Water Units
1. NorthStar Hot Water Pressure Washer (300 PSI / Diesel Burner): A leading contractor‑grade model known for reliability and high heat output.
2. Powerhorse Propane‑Fired Hot Water Pressure Washer: Easier to maintain than diesel units and excellent for oil, grease, and industrial maintenance.
Cold Water vs Hot Water: Which Should Contractors Buy?
Choose Cold Water If You:
Do standard power washing (homes, driveways, decks)
Want lower equipment cost and maintenance
Need portability and long run times
Choose Hot Water If You:
Clean grease, oil, or industrial surfaces
Work with commercial contracts
Need faster results with less detergent
Want to offer premium‑priced services
Most professional power washing companies eventually use both, adding a hot water unit as they expand into commercial or industrial work.
