Benefits of a Gas Pressure Washer
Gas pressure washers are ideal for heavy-duty cleaning projects. They do a magnificent job of cleaning exterior surfaces that require more cleaning power. With them, you can make cars, driveways, decks, patios, and walkways look new in a matter of minutes.
The main benefit of gas pressure washers is the fact they provide more power and therefore, can clean heavy-duty dirt and grime. Gas pressure washers work like a charm on everything from dust-coated to oil-stained surfaces. For that reason, they can usually be found on construction sites, where more power and efficiency is required.
Also, gas pressure washers are ideal for areas where there's no access to a power outlet. Because these machines work on gas, you don't need to plug them into an outlet. As long as you keep the tank full, a gas pressure washer will work anywhere. Therefore, you'll have more mobility, reach distant areas, and avoid tripping on tangled cords.

Different Kinds of Gas Pressure Washers
If you're about to pick a gas pressure washer, you want to make sure that you get the right model for your particular application. Although there are not many types of gas pressure washers, there's one thing that differentiates one model from another. We break down all the necessary information in the sections below.
DIY Gas Pressure Washers
All gas pressure washers come with similar specifications. They have powerful engines that work on gas and provide a high output. However, there is a difference in the overall power of the units. Some of them are budget-friendly but have less power, while others are extremely powerful and, consequently, very expensive.
The units with less cleaning power are mostly designed for home purposes. They are very convenient for cleaning pavements, sidewalks, cars, and more. Although not as powerful as commercial gas models, they are still more efficient than electric pressure washers.
Commercial Gas Pressure Washers
Gas pressure washers can turn out to be rather expensive. That's because of the extremely powerful engines that provide immense cleaning power. The higher the CPU (cleaning power units), the more powerful and expensive the washer turns out to be.
Gas pressure washers with high CPU are mostly used for commercial purposes. They can be found on construction sites where high cleaning power is needed for removing heavy dirt and stubborn stains. Although they are suitable for home purposes as well, most people don't need excessive power for regular home jobs.
What to Consider When Buying a Gas Pressure Washer
Gas pressure washers are convenient machines that can make your life a lot easier. You don't have to hire a professional for cleaning your backyard patio and vehicles. With a gas pressure washer, you get to do it all on your own without much effort. Still, it's important to pick a proper machine for the job. You want to get the best gas pressure washer for your particular application. That's why we listed some of the most important things to consider when buying a gas pressure washer. Once you get through our general guide, you can get back to the product recommendations and choose the perfect model for yourself.
One of the first things to consider when buying a gas pressure washer is the CPU or cleaning power units. CPU stands for the overall efficiency and performance of the washer—the higher the number, the better and faster the unit will clean. You can calculate it by multiplying PSI and GPM ratings.
PSI (pounds per square inch) measures the pressure that a compressor can produce per square inch of space. GPM (gallons per minute) stands for the volume of water the washer can pump per minute. Both ratings are incredibly important. You don't want to get a washer that has high PSI but low GPM because it won't be able to supply enough water.
Consider your application before deciding on a particular unit. Average household gas pressure washers have around 2500-3300 PSI and 2-2.5 GPM. Still, you can get more or less powerful ones, depending on the application.
Another important thing to consider is the overall portability of each gas pressure washer. Although these models are more portable than corded ones, there are still some things to keep in mind before the purchase.
For example, it's crucial to pick a model that doesn't weigh too much. You want to be able to carry along the washer without putting in a lot of effort. On the other hand, if you need an extremely powerful unit, you want to look for large wheels. That way, the pressure washer that accommodates a heavy engine can be easily rolled around the household.
You also want to make sure the washer is built to last. Whether you're planning to use it in your backyard or at the construction site, you want to have a unit that can withstand heavy and daily abuse. Well-built gas pressure washers can be used for different projects and last for a while.
Additionally, it's essential to get an ergonomically designed gas pressure washer. Thanks to the user-friendly design, you can handle the machine with ease and get more work done. Look for the pressure washers that have cushioned handles and convenient spray triggers.
When buying a gas pressure washer, you can look for some features that would reduce the effort you have to put in the cleaning process. For example, some machines have a crank-operated mechanism for rolling the hose, while others have a hose storage compartment.
Another great extra feature is the soap tank. It allows you to spray water and soap onto surfaces for a thorough cleanup. Additionally, you might want to look for some added protection if you're planning to run the washer over rough terrains. Steel frames might be necessary to protect the unit from bumps and impacts.
Tips for Using Gas Pressure Washers
Consider getting some accessories to complement your gas pressure washer. They will allow you to achieve more efficiency and get the job done easier. For example, there are specially designed nozzles that control the intensity of the water output. With them, you can adjust the flow according to each particular job.
Also, make sure to properly store the gas pressure washer. Even when the machine is resistant to weather, it's smart to keep it in a dry and dark place. That way, you can avoid exposure to threats and prolong the overall lifespan of the washer.
When storing the pressure washer, use the built-in compartment for storing the hose. If your particular unit doesn't have one, try to store the hose properly. If it lays twisted or cranked, the hose is likely to get damaged easier.
- Check for accessories such as nozzles that can help you get the job done faster.
- Make sure to properly store the washer to prolong its lifespan.
- Use a built-in storage compartment for storing the hose or lay it without twisting the material.
