pressure washer pump. All methods do the same thing, turn the
pump. It is important to use enough horsepower to match the
requirements of the pump.
Many pressure washer manufacturers have settled on Honda as the standard engine for their machines. Briggs and Subaru have also been used as an alternative to Honda. Recently there has been an influx of inexpensive engines from China, which have had varied success. Reliability has been a problem. While many Chinese made engines look exactly like a Honda, they did not run like a Honda, with major problems showing up after only a few hours of running. Honda have responded to these knock-offs by going after sellers of any engine that looks like a Honda, using copyright laws.
If you are contemplating purchasing a pressure washer with a gas engine made in China make sure you understand the possible problems. Also, verify the reliability of the dealer for warranty and parts and service.

Don't expect too much from one of these units and be prepared to replace it on occasion. If you have lots of time and patience then one of these will do the job.
Most commercial buildings and facilities do have higher voltages available allowing for small to very large pressures and flows In-plant applications are ideal for electric powered washer. With no fuel or fumes to deal with they can be installed anywhere in a plant.
Many operations such as boats, barges, trucks, cranes, concrete pump trucks, excavators, tractors, loaders and farm machinery have a hydraulic source available. Another great application for a hydraulic powered pressure washer is that they can be used in remote and explosive environments where gas engines or electric motors can not be used.
