A pressure washer is a useful household item for keeping outdoor surfaces clean. With a high-quality gas pressure washer, you can clean your sidewalk, driveway, siding, fence, concrete floor, deck, and patio with maximum performance and professional quality. The best gas pressure washers contain multiple spray nozzles to provide a powerful and efficient stream of water. A soap nozzle can be extremely useful for washing vehicles, including cars, trucks, SUVs, boats, trailers, and RVs. A high pressure, long-length hose system and high-quality wheels are important pressure washer features that provide mobility and flexibility.

Summary List

Another one of our top picks is the Simpson MSH3125 MegaShot gas pressure washer. The unit provides 3200 PSI at 2.5 GPM, which makes it incredibly efficient for all kinds of cleaning purposes. You can use it for home jobs as well as construction applications. Thanks to the high power output, the washer removes the heaviest dirt and most stubborn stains. The Simpson gas pressure washer features a sturdy and durable construction. The steel frame makes it even more resistant to outside threats. Additionally, the unit has 10-inch pneumatic wheels and rolls easily over different surfaces. The package also includes five quick-connect nozzle tips for more precision and control over the cleaning process. However, the unit doesn't have a built-in soap tank. It's also quite loud, so you might want to use earplugs during operation. Lastly, the handle is somewhat awkwardly positioned and a tad short for tall people.

This is another highly-reliable Simpson gas pressure washer. It offers 3100 PSI at 2.4 GPM, which is rather impressive. Because of the high water flow, the washer can clean all kinds of heavy dirt and debris. It's ideal for home purposes, especially for cleaning driveways, cars, RVs, and more. Users also love the overall design of the Simpson washer. It comes with a maintenance-free axial cam pump, a 25-foot long hose, and M22 connectors. The unit also features a sturdy and durable steel frame and a hose that is resistant to tangling and abrasion. Furthermore, the package includes five nozzle tips and a two-year limited warranty on the engine. The product is not without drawbacks, however. First, the handle is not very tall, and some users report that the hose is a tad short, which restricts overall mobility during the cleanup. Second, the water hose attachment is too close to the pressure hose attachment, so it's difficult to connect and disconnect it.

If you're looking for an affordable gas pressure washer, you might want to check out this model from A-iPower. It's a powerful machine that delivers 2700 PSI and 2.3 GPM. You can clean most surfaces from heavy dirt and grime, including sidewalks, driveways, patios, vehicles, and more. The washer has an axial cam pump and comes with three nozzle tips for a wide range of applications. The 25-foot-long hose allows for excellent reach, and the 8-inch wheels ensure more portability. Overall, the unit is easy to operate and allows for effortless cleaning. Thanks to the lightweight design, the A-iPower gas pressure washer is highly portable and ideal for home use. However, the hose is not protected against overheating. It might melt due to the high temperature coming from the engine. To avoid that from happening, you might need to take frequent breaks while using it. Also, the on/off switch is somewhat flimsy and might break easily.

We just had to include another Simpson gas pressure washer. It's a compact and portable machine you can use around the house for cleaning all kinds of surfaces. With the 2400 PSI and 2.0 GPM, the machine is perfect for light to medium demanding jobs. This little unit is ergonomically designed and super easy to maneuver. It comes with an axial cam pump, a flexible hose, and three spray nozzles. All of this allows for more freedom and precision during the cleaning process. Additionally, the machine has a steel frame construction and folds down for quick and easy storage. It's quite durable, so you'll definitely be able to use it for a while. However, keep in mind that the tank is not very large. Depending on the project, you might need to stop in the middle of the job to refill it. Also, the handle is not very tall, and both the garden and pressure hose connectors are located at the bottom of the machine. That makes using and storing the pressure washer more challenging.

The TACKLIFE gas pressure washer features a 173cc OHV engine that pumps 2.4 gallons per minute. It has a maximum pressure of 3200 PSI and puts out 6.5 horsepower, so it's built for hard-to-remove stains. The manufacturer boasts that the unit provides 50 percent more cleaning power compared to high-pressure electric power washers. The device is very efficient, and you don't have to worry about tangled wires when using it. The washer comes with five quick-connect nozzles (0, 15, 25, and 40 degrees, as well as a soap nozzle), and it's designed for use on vehicles, garages, roofs, and other surfaces. It has 11-inch wheels, and the detergent tank is 0.8 gallons large. The unit also features a 25-foot pressure hose and metal spray gun designed to last a long time. Also, TACKLIFE includes a 24-month service contract for the engine and 12 months for the frame and accessories, which provide users with some peace of mind. One downside is there is no hook to wrap the hose around when you're using the power washer. There have also been some complaints that there is no oil drain plug, which is very inconvenient.

The Generac gas pressure washer is designed to clean your home and patio, as well as your car or truck. It features 3100 PSI and has an electric start and auto choke, which are reliable and make it easy to operate. The unit comes with a lithium-ion battery designed to last up to 18 months. A charger is also included. The detergent tank is simple to access, and it comes with a vertical axial cam pump and extended connections, so assembly and cleaning are seamless. The spray gun is adjustable based on the task. The settings include car, concrete, soap, and wood. It also comes with four quick-change nozzles: 0, 25, and 40 degrees, and soap. This pressure washer also has a two-year limited warranty. Overall, it has a lot of power, and the hose doesn't kink when you're using it. The wand is also lightweight and doesn't make you too tired when you use it. One problem is that the wheels are a little small if you use it when climbing stairs. The handle is also a bit short if you're on the taller side. In addition, the plastic parts are a little flimsy, and the hose is a little short.

The YARD FORCE 3100 PSI gas pressure washer is built with a Briggs & Stratton 875EXi engine with an axial cam pump that's supported by a two-year warranty. It has a remote electric start, so you can easily operate it while you're on a ladder or as far away as 100 feet away. The unit comes with a 20-volt lithium-ion battery that accommodates up to 100 starts when it's fully charged. This pressure washer has a metal frame that provides storage for the spray gun, four quick-connect nozzles (0, 25, and 40 degrees, and soap), and a 25-foot hose. It features 12-inch wheels designed to tackle various terrain and a one-gallon soap tank that allows you to do the job longer without refilling the machine. The metal wand has brass QC fittings that work with most accessories, and the unit is PWMA-certified. One problem with this machine is that the directions are not the greatest and may include a misprint, which can cause problems when you're attempting to pair the remote. Also, there have been complaints that the hose is stiff and not very maneuverable.

The Duromax gas-powered pressure washer has 3100 PSI and pumps 2.5 gallons of water per minute. The machine is designed for everything from cleaning your driveway and sidewalks to cleaning your gutters and roof. It features an engine that can put out 7 horsepower and shuts down when the oil gets low. It also has a 140-degree Fahrenheit thermal relief valve and onboard storage for the spray gun, hose, and six quick-connect nozzles (0, 15, 25, and 45 degrees, soap, and turbo). The unit has a built-in detergent reservoir and a three-piston axial cam brass head pump. The frame is durable and designed to protect the engine and pump. It's also simple to lift. The spray gun has a cushioned grip and is easy to use without causing fatigue. Overall, it provides adequate power to cut through dirt and grime and is easy to start. It also takes about 15 minutes to assemble if you're mechanically inclined. Unfortunately, some of the parts are fragile, such as the wand holder. The hose is also not the best quality and may fail if it comes into contact with the muffler.

The Champion Power Equipment gas pressure washer has 3200 PSI, which is greater than some other choices. It features a 224cc single-cylinder OHV engine and a high-performance Annovi Reverberi axial cam pump. The machine comes with a quick-connect spray gun, wand, and five nozzles: 0, 15, 25, and 40 degrees, and soap. It also has a 25-foot quick-disconnect hose and detergent tank. One of the best things about this machine is the spray gun trigger is ergonomically designed to minimize fatigue during use. It also has space to store the hose, trigger gun, and spray wand. In addition, Champion provides a two-year limited warranty and lifetime technical support should you need it. Users report that it's powerful, easy to assemble, and is compact enough to easily store when it's not in use. One downside is the frame vibrates a bit, which may wear down the wheels over time. It may also be hard to find replacement parts if something fails, and it may rust prematurely.

The TACKLIFE is a 3300PSI gas pressure washer with a 212cc engine that gets 6.5 horsepower. It's larger than the previous TACKLIFE entry with a 30-foot pressure hose, 1.2-gallon soap tank, and five nozzles (0, 15, 25, and 40 degrees, and soap). This machine is 80 percent more powerful than electric counterparts, according to the manufacturer. It's also highly efficient, and there is minimal wire entanglement. The unit is designed for use on homes, RVs, vehicles, boats, lawn equipment, and more. The anti-slip wheels are detachable, and the machine is easy to assemble. It comes with several accessories, and the spray gun has a safety lock, so the pump shuts off if the trigger is not engaged. The steel frame is designed to hold the water pipe, spray gun, and five nozzles. It meets CARB certification and is backed by a two-year warranty. Some users have complained that the unit becomes more and more difficult to start using the pull cable over time. Also, the included hose isn't the best quality and may kink and twist.

Overall, it starts on the first pull, has good power, and is easy to handle. However, the wand could be a little longer for more accessibility.

Best Gas Pressure Washers Buying Guide

If you're interested in buying the best possible gas pressure washer, it's crucial to learn all you can about the machine. Once you learn all about the product, you can pick the one that works the best for your particular application. For that reason, we composed a general guide for gas pressure washers. We tried to include not only the most important features to look for, but also answer frequently-asked questions so that users will hopefully find the best gas pressure washers and be fully satisfied with their purchases. 

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. 

  • Ideal for heavy-duty cleaning jobs where more efficiency and power is required
  • Remove stubborn stains and heavy dirt
  • Allows for more flexibility and mobility

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. 

Extra Features 

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.


Lastly, we answered some of the most frequently-asked questions about gas pressure washers. To pick the best machine for the job, it's essential to have all the necessary information about it. Therefore, we wanted to make sure you'll get all your questions answered, so you can pick the perfect model of gas pressure washer for yourself.

Q. How do I test a gas pressure washer?

A: To avoid damaging the cleaning surface, test the gas pressure washer on the pavement or some kind of wood. That way, you can determine the strength of the flow. 

Q. What is the best gas pressure washer?

A: It depends on your needs and the application. Some people need less powerful washers, while others need an extra-high flow for better efficiency. 

Q. What is the purpose of a gas pressure washer?

A: Gas pressure washers are used for outside deep-cleaning. They are highly beneficial when it comes to removing heavy dirt and stubborn stains due to their high power output.
