FAQ: How is a cold water pressure washer different from a hot water pressure washer?

The main difference is that cold water pressure washers do not heat the water, while hot water pressure washers have a burner system that heats the water before spraying it. Cold water pressure washers are great for general cleaning tasks like washing driveways, sidewalks, decks, vehicles, and siding. However, they are less effective at cutting through grease, oil, and heavy industrial grime, which is where hot water machines excel.
