Electric Pressure Washer Terms You Must Know
- Gallons Per Minutes (GPM)
Gallon per minute is the water flow rate per minute. The most common GPM range is 1 to 5 gallons per minute. More water flow consumes less time to clean a particular location. The higher GPM pressure washer is ideal for professionals to carry out a heavy and frequent volume of cleaning projects. Comparatively, light cleaning projects need a lower GPM machine.
- Pounds per Square Inch (PSI)
Pound per square inch (PSI) refers to the pressure rate. The common PSI range is from 1000 to 3500. It indicates the pushing forces, though the original forces on the ground depending on the spray wand nozzle and the distance between the surface and the nozzle you hold.

Not electric pressure cleaner, especially, gas washer owns an engine to generate power to the pump.

For example, an identical pressure washer is Honda GCV190. Here the 190 indicates the engine’ cubic centimeter (CC). The stronger the engine the higher the pounds per square inch.
The electric pressure washer uses a motor to generate power to pump. They are illustrated with their Watts and Amps that provide the energy.
There are three types of the motor of an electric pressure washer. They are induction motors, universal motors, and water-cooled motors.
The induction motors the medium-duty motor that ensures an extraordinary performance. It is very quiet and durable. Generally, the commercial duty pressure washer is equipped with an induction motor.

It would be more flexible, longer-lasting and lighter to move the machine easily.
