However to produce greater pressure, more horsepower is required to force the water through the smaller hole. The smaller the nozzle orifice, the more pressure is potentially produced. The narrow diameter of the nozzle increases the water's velocity and, consequently, its impact and cleaning power. Without the nozzle the impact of the water from the end of the pressure washer hose is similar to that from a garden hose. By restricting the flow with the nozzle, much like you do by placing your thumb over the end of a garden hose, the pressure washer produces pressure.

The pump is a positive displacement pump that forces a specific amount of water flow from the outlet. The pump is typically powered by a gasoline engine, an electric motor, or a diesel engine. Warm or hot water, or steam, melts fats and oils so that it is easier for the soap or detergent to dissolve the soil and pull it away into the rinse water.Ī pressure washer is a mechanical device that uses a pump to generate a high-pressure stream of water to clean surfaces. As the detergent emulsifies the grime, breaking the chemical bond, the blasting effect of the pressurized water strips the dirt from the surface, while the flowing water rinses the detergent and soil away.

This mechanical energy is provided by the pressure washer. Detergents cannot accomplish much until some mechanical energy or agitation is added into the equation. Basically, soap allows oil and water to mix so that oily grime can be removed during rinsing. Adding a detergent, or other cleaning chemical, or using hot water, while agitating or brushing the surface, significantly enhances the cleaning power of the pressure washer.ĭetergents and soaps are used for cleaning because pure water can't remove oily, organic soiling.

Sometimes even the force of high pressure water needed to break these chemical bonds is insufficient to get the surface clean without requiring excessive pressure, that is either impracticable or would damage the surface. Often dirt is mixed with grease or oil, or other substances, which chemically bond the dirt to the surface you are trying to clean. A pressure washer cleans by creating a high pressure stream of water that hits the surface with a large amount of kinetic energy, thus removing the dirt mechanically, while providing a constant flow of water to wash the dirt away. Understanding the cleaning process is essential to the effective use of a pressure washer.
