Today’s pressure washers are more powerful and versatile than ever, and the sheer number of options available can make it difficult to know which one is right for you. If you’re in the market for a pressure washer, this guide will help you learn about three things you never knew about them along with information on how to choose one that meets your needs.

Not all surfaces will react well to the pressure washer

Pressure washers can be a great addition to any home or business, but they’re not the best choice for all surfaces. 

For example, pressure washers are not recommended for cars. Many people have been using pressure washers to clean their cars, but they can cause more harm than good. Using a pressure washer can affect or nick the paint, resulting in rust. A car wash, as well as a garden hose, will usually suffice.

Cleaning your roof with a pressure washer is also risky, not to mention possibly harmful. Roof shingles can also be loosened by a strong stream of water. If your shingles are asphalt, it can wipe away the embedded granules that help your roof last longer.

Bigger isn’t always better

The bigger the pressure washer, the more powerful it will be. However, a larger machine doesn’t necessarily mean it’s more effective. 

If your pressure washer is too big for your needs, then it won’t be very useful for cleaning your house or car. It could even cause problems with noise levels in your neighborhood as well as carbon emissions from running it so often.

Before you go out and buy one of those $1,000+ models, you should know that there’s more than one type of pressure washer on the market today. Some small compact models are perfect for cleaning driveways or small residential properties, while others are larger and more powerful.

The right nozzle eliminates potential damage to your property

If you want to do a good job with your pressure washer, you must have a nozzle that has the right size for your machine. This means you will be able to use it as efficiently as possible. A small nozzle won’t be able to clean as well as a large one would in most cases.

If you want to avoid breaking anything on your property, ensure that your nozzle has plenty of distance between it and any surfaces. You don’t want it hitting anything too hard or too close together. Just go ahead and spray as much water around as possible until everything is drenched evenly!


Pressure washers are powerful machines that, when used improperly, can cause serious damage to your property. These machines can be complex for anyone unless you educate yourself on how they work and how to operate them safely. With that said, pressure washers are effective tools for cleaning large areas quickly that make a difference in everyday life.
