High Pressure Washer Buying Guide – 2021 Edition

When choosing a high pressure washer, it is important to consider your needs and think about whether you need an industrial washer or not. This buying guide will explain the difference between commercial and industrial high pressure washers and compare some of the best options on the market right now. 

Type of pressure washers 

Most people are familiar with pressure washers and they might have used them to clean their driveway or their car. These electric powered pressure washers are fine for home use, but they are not adequate for heavy duty applications. The benefit of using an electric high pressure washer is that they are easy to plug in and use and they’re lightweight and portable. Gas powered high pressure washers are more powerful than their electric counterparts and are much better suited to industrial applications. A professional pressure washer is run on diesel or petrol and is usually much larger. It is these high pressure washers that we will focus on in this buying guide. 

What to look for in a high pressure washer 

When comparing different high pressure washers and trying to determine which one is right for your needs, there are a few important things to consider. 

The PSI 

The PSI (pounds per square inch) tells you how much pressure is used to propel the water from the washer. Essentially, it tells you how powerful the high pressure washer is. This is one of the most important things to consider because the higher the pressure, the more you spend. So, it’s important to find a washer that has high enough pressure, but also to make sure that you don’t pay for a high pressure washer that far exceeds your needs. 

Water flow rate 

The water flow rate tells you how much water the pressure washer produces per minute in litres. If you are cleaning large areas, the water flow rate is just as important as the PSI. The larger the flow rate, the quicker it will be to clean a large surface area. 

The Pump 

The pump is what pushes the water out of the pressure washer. A better quality pump helps to achieve a more consistent flow of water and a higher PSI and water flow rate. The pump also has a role to play where reliability is concerned. 

Engine type 

Reliability is so important in industrial high pressure washers, so it’s important that you check the engine type. Although water flow rate and PSI are the main things to consider, don’t make sacrifices on engine quality.
