2. Pressure Rating The pressure rating of a pressure washer, measured in pounds per square inch (PSI), significantly affects its price. Lower PSI units (around 1,300-1,500 PSI) are ideal for delicate surfaces and cost less, while high-end models (over 3,000 PSI) offer intense cleaning power, suitable for professionals and heavy-duty applications. As expected, higher PSI models come with higher price tags.
