When you are looking for a pressure washer to buy, it can be difficult to figure out which one is the best for your needs. PSI (pounds per square inch) is an important spec to look at when making your decision, but it’s not the only thing you need to consider. In this blog post, we will go over the different factors you need to think about when choosing a pressure washer and provide a PSI chart that will help you find the perfect one for your needs!

Factors to consider when purchasing a pressure washer


There are a few different things you need to take into account when purchasing a pressure washer. The first is what PSI you need. PSI is a measure of how much water pressure the machine produces. The higher the PSI, the more powerful the pressure washer will be. However, too much PSI can damage surfaces, so it’s important to choose the right one for your needs.


Another factor to consider is GPM (gallons per minute). This measures how much water the pressure washer can output in a minute. A higher GPM means that the machine can clean larger areas in less time.


You also need to think about what type of nozzle you need. There are three different types of nozzles: wide-angle, pencil, and fan. Wide-angle nozzles are best for large areas, while pencil nozzles are better for getting into small spaces. Fan nozzles produce a narrower stream of water that is great for reaching high places.

Power source

Finally, you need to decide what kind of power source you want. Pressure washers can be powered by electricity, gas, or diesel. Each has its own advantages and disadvantages.

  • Electric pressure washers are the most popular type because they are easy to use and maintain. They also don’t produce as much noise as gas or diesel models. However, they require a power source, so you’ll need to have an outlet nearby when using one.
  • Gas pressure washers are more powerful than electric models and can be used without a power source. However, they require more maintenance and produce more noise.
  • Diesel pressure washers are the most powerful type, but they are also the heaviest and most expensive. They are best for commercial use.
