As the name implies, a pressure washer is a piece of equipment used for cleaning different surfaces with high pressure levels. In this process, a high pressure stream of water is aimed at the object to be cleaned. The water then removes tough stains, grease and other particles, leaving the surface clean. In some applications, detergent is added to the water to make the cleaning process fast, easy and effective. Such equipment is used for industrial and commercial applications, like cleaning trucks, pools, pavements, doors, machinery and so on.

There are many different types of pressure washers, varying by power methods, temperature options, heating methods, pressure levels, flow rates, and mobility. Often the most significant among these variations is the power method. There are electric pressure washers, gas pressure washers and propane pressure washers. Each of these power methods has pros and cons; let us look at some of them.
Weight
Electric washers are lighter as they do not have gasoline or propane tanks along with them. However, electric pressure washers do require that the unit is plugged into an electrical outlet, making them ideal for indoor applications where an electrical source will be readily available.
Noise
Electric pressure washers are less noisy as compared to their counterparts, gas and propane. This too makes electric-powered equipment ideal for indoor locations where the level of noise must be taken into consideration, as with nursing homes and hospitals.
Exhaust
Unlike gas and propane pressure washing equipment, the electric equipment does not emit exhaust. Therefore, it is best suited for indoors. Due to their production of exhaust, gas units should be used outdoors or in very well-ventilated areas.
Power
Gas and propane pressure washers are often more powerful due to their use of high-powered motors. However, the best electric pressure washer do offer high pressure levels and flow rates to rival the power of gas or propane powered machines. Additionally, all power methods can feature cold water, hot water, or steam temperatures depending upon the configuration of the machine. Higher temperatures mean greater cleaning power, making steam pressure washers the most effective. For a more versatile machine, consider equipment that can operate in all three depending on the application at hand.
Mobility
As far as mobility is concerned, electric pressure cleaning machines do not fare as well as gas and propane ones. Since an electric machine needs an electrical connection, it is not ideal for outdoors and other places where there is no power supply. At such places, gas pressure washer and propane pressure cleaning equipment should be used. These are also known as mobile pressure washers. You should never try using electric pressure cleaning equipment with cord extenders, as this method is unsafe.
Ease of Use and Maintenance
Electric pressure washers need less maintenance than gas and propane pressure cleaning equipment. Moreover, these machines are much easier to operate; just turn on the power supply and the equipment is ready to use. While gas and propane equipment may be difficult to operate, this difficulty is often overlooked due to their advanced power offerings.

You should choose the pressure cleaning machine depending upon the purpose for which you intend to use it. For indoor, commercial purposes, an electric pressure washer might be ideal. While the power method is important, remember that there are many other options to choose from when finding the right machine. Consider the temperature options, heating methods, power methods, pressure levels, flow rates, and mobility configurations when shopping for a pressure washing machine.
