So which is best? In most applications the 1000 psi unit would clean more efficiently even though it has only two thirds the pressure. Both have the same amount of cleaning units (3000) but vary significantly in pressure. If the design criteria called for more pressure, a pump would be selected for 2 gpm at 1500 psi. A pump could be selected for output of 3 gpm at 1000 psi. For example, a pressure washer with a 2 horsepower electric motor is capable of producing 3000 cleaning units. Cleaning units is calculated simply by multiplying pressure (psi) times flow (gpm). The terminology used for this measurement is “cleaning units”. Proper balance of flow and pressure: With a given amount of horsepower, a pressure washer design will result in a tradeoff between pressure and flow. Another problem with excessive pressure is that without proper experience and operator training, the surface may be damaged instead of cleaned. For instance, 4 gallons per minute at 4000 psi popular with the average user but a professional cleaning company will select a 5 gpm model at 3000 psi to complete the job faster even though both professional pressure washers have the same horsepower. In the pressure washer industry, we have seen a trend that the more popular selling models have more pressure and less flow except with the professional contract cleaners who understand the efficiency of their equipment better because they use it every day. Alternatively, you can also contact their Customer Support: 1-80.Is more pressure better? People who pressure wash occasionally will often select a pressure washer with the highest spray pressure without considering flow which typically delivers less than ideal cleaning results.
