While the terms are frequently used interchangeably by homeowners, the primary technical difference is water temperature. A standard pressure washer uses unheated ambient tap water, relying entirely on high-pressure mechanical force to blast away dirt. A power washer features an integrated heating element that heats the water to high temperatures, creating hot water or steam that dissolves grease, oil, and stubborn biological contaminants significantly faster than cold water alone.
