Pressure washers use water to remove grime from your patio or patio furniture, driveway, fence, and other surfaces. If you want a clean outdoor space without paying professional service fees, a gas pressure washer typically provides a higher power level at a smaller price point than electric pressure washers.
However, finding the best gas pressure washer for your DIY needs depends on a variety of factors, such as what type and size job you’re looking to complete, your budget, the material of the surface you’re washing, and how much mobility you need the washer to have. Gas pressure washers can cost anywhere from $150 to $200 for a budget-friendly light-duty model, to over $500 for high-motor devices for larger projects.
To help you narrow down your options and find the best gas pressure washer for your needs, we examined the top models on the market. Overall, our top choice is the DeWalt DXPW3300-S Gas Pressure Washer, which has a powerful motor, a variety of quick-change nozzle tips, and large wheels for added mobility.

What Are People Saying About the Dewalt DXPW3300-S Gas Pressure Washer?
We found that customers who gave this product a positive review were impressed with its straightforward assembly, excellent power level, and ease of use and maneuverability. However, a few customers had issues with the design of this pressure washer, specifically regarding the hose attachment and the handle alignment.
“This pressure washer is a beast! … Ease of assembly is great. Directions are logical and clear. The unit is very easy to maneuver, unlike the old washer I had. The hose hookups are right were they should be instead of under the rear of the unit, requiring gymnastic and barked knuckles to attach the hose. The engine and pump are very powerful. This medium priced unit just set the bar very high for the rest of the competition. Very pleased with the unit. Would buy again.” — Vincent L. Wilde via Amazon
“Looks great, seems to have plenty of pressure. The design could use some help. Once the hose is connected to the wand, the holder for the wand is useless, it falls out. The only workaround is to remove the hose each time. … The water outlet for the wand should be on the other side I feel to not work against the natural fall of the wand and pressure hose when attached. .” — Ken via Amazon

What Are People Saying About the Westinghouse Gas Pressure Washer?
Happy Amazon customers said that this power washer was easy to assemble. In addition, other reviewers praised the manufacturer for making the connectors out of metal instead of plastic. However, negative reviews said that the motor failed after only a few uses. Some also said that the other parts of the machine felt flimsy.
“Got this product and I was able to quickly assemble without problems. All the parts were inside the box and labeled correctly. I’ve used it a couple of times already. It works excellently. It’s got a lot of power. Much better than the plug-in that I had in the past. I’m really pleased with my purchase. Worth every penny.” — SandaLee via Amazon
“The pressure washer works very well when it runs. The design is flawed for the water inlet allowing the water hose to vibrate against the wheel of the unit. It is not easy to reroute the input water hose, and the water hose must be tied up elsewhere. The new water hose cost me $26 dollars. The engine turned off several times during the first use, and the oil, water, and fuel were fine. This was baffling and did not occur during the 2nd use. Maybe the water hose was damaged by the pressure washer, and that was causing a low water pressure, while I was unaware of the damage being created at the time. Annoying.” — Eddie in VA via Amazon

What Are People Saying About the Simpson Cleaning PowerShot Gas Pressure Washer?
Pleased customers experienced excellent customer service from the manufacturer. Others pointed out that this gas pressure washer was easy to use and highly maneuverable. However, some unhappy customers said that this washer leaked oil and was poorly packaged, which sometimes led to damage.
“…The Simpson starts easily and runs like a champ. First day out, I used it for 6 straight hours, stopping only for fuel … and it never missed a beat. Have used it for a couple of hours on three other occasions, and ran perfectly every time. It’s really more power than I need, but really happy I decided to go to the triplex pump and the peace of mind it provides in not having to worry about it failing or wearing out. Plus, I find I can run it with the throttle only midway and still get plenty of power but with less noise. The low profile is great for storage.” — JRM via Amazon
“My experience mirrors many reviews on the item. So far, it is a great residential washer. The biggest complaint is very poor packaging. Simpson may as well shipped it bare. The box was split and ripped it had been retapped and then ripped apart multiple times, judging from the multiple tape layers. All the internal bracing was loose or missing. The included motor oil had fallen out. But the damage was minor. I don’t understand why a rational person would put a nice power washer in a box marginally strong enough to hold tissue paper. Summary: good washer at a good price but good luck with shipping.” — Kathy Herman via Amazon
Best Value
BILT HARD Gas Pressure Washer
- $269.99

Good For: Homeowners looking for a budget-friendly pressure washer that can still deliver results.
What Are People Saying About the BILT HARD Gas Pressure Washer?
Our team noticed that several customers who gave this product a positive review appreciated its interchangeable quick-connect nozzles and its high power level, especially for its size and price point. Several others also commented on how easy it was to set up and start. On the other hand, some customers had issues with the hose breaking after minimal use, and others said the soap cap was cheaply made.
“This thing is a powerhouse! I absolutely love it! …With recent construction of the driveway the red clay dirt just ran off the surface of the siding! I am so happy with the results. With five interchange nozzle choices it wasn’t hard to find the right nozzle for the job. They quickly snap into place, and made the job efficient and quick. Not super heavy to move around which for me is a plus!” — Barbara Kipley via Amazon
“The pressure washer works great. Easy to assemble and easy to start. However, the one feature that should be changed is the soap tank cap. After I finished my wash, I picked the unit up to put it away and the snap lid on the soap tank popped open and covered me and my shop floor with liquid soap.” — Allen Baxton via Amazon

Generac Gas Powered Residential Pressure Washer

Good for: Homeowners looking for a well-designed gas pressure washer that’s easy to use.
What Are People Saying About the Generac Gas Powered Residential Pressure Washer?
We noted that those who were satisfied with this gas pressure washer liked that it had a durable construction and was lightweight and easy to move around. Others were impressed with its easy-start design. However, others found the hose connection to be difficult to manage, and others said they couldn’t get the soap dispenser to work properly.
“…Pretty much every part is already pre-mounted. It is amazing how quickly you can put this product together. … Everything takes no less than 15 minutes to put together, and you’re on your way. Honestly, it started super easy on the first crank. I cleaned my driveway and my deck, and the results were above my expectations… makes an amazing product, and I totally recommend this gas-operated pressure washer.” — Alain Loyer via Amazon
“…The wheels are mounted in the cheapest way possible. They wobble side to side as you roll it around. The pressure hose is typical — very rigid. The pressure hose and garden hose connects are very close to each other making it a little hard to connect. I intend to add a fitting on the water input to make it come out the back, giving me more room. My gripes are by no means deal breakers.” — Amazon Customer via Amazon
What To Know Before Buying a Gas Pressure Washer
The right tools make heavy-duty cleaning jobs easy and effortless. To find the best pressure washer for your needs, there are several important factors you need to take into consideration. First, consider the engine size and power level (in GPM) of the pressure washer. Next, examine the hose connections, spray wand, and other features that stand out. Finally, consider the portability and weight of the pressure washer, especially if you plan on moving it frequently from place to place.
Read our buying guide below for more information on how to select the best gas-powered pressure washer for your needs.
What should you look for in the engine of a gas pressure washer?
Most gas pressure washers have four-stroke engines, but some have two-stroke engines. Four-stroke engines last longer, are quieter, and release fewer emissions than their two-stroke counterparts. Two-stroke engines are commonly found in smaller tools, such as gas chainsaws, and run faster than four-stroke ones.
Another important indicator of an engine’s quality is its horsepower (hp), which tells you how powerful the engine is. A higher hp rating indicates more power.
What hose connections does a gas pressure washer have?
Your gas pressure washer should come with multiple connection ports for different hoses or attachments. These connections should be easy to access and accommodate other hoses that didn’t originally come with the product, allowing for customized cleaning jobs.
How do you determine the portability of a pressure washer?
Gas pressure washers can be heavy, with the smallest models weighing around 60 pounds. If you want to perform several tasks around your yard, look for a model with wheels and a handle to help you move it from one location to another.
How is the pressure level measured in gas pressure washers?
The pressure of the water that the machine releases is measured in pounds per square inch (psi). A higher psi gives you more power to cut through dirt and grime. Most machines have adjustable pressure settings, allowing you to change the water pressure to match a variety of jobs.
What are spray wands in pressure washers?
Pressure washers have spray guns with hoses that usually extend between 25 and 35 feet. These spray guns will also come with several spray nozzles.
How is volume determined in a pressure washer?
Gallons per minute (GPM) describes how much water a machine supplies. Look for a machine with both high pressure and volume for it to clean large areas with tough grime.
What are reputable brands that sell pressure washers?
Although there are dozens of models that make gas pressure washers, some of the most reliable brands for this type of power equipment include:
- BLACK + DECKER
- DEWALT
- Earth Wise
- Generac
- Greenworks
- Karcher
- Mantis
- Ryobi
- Simpson
- Stihl
- SunJoe
- WEN
- Westinghouse
Frequently Asked Questions About Gas Pressure Washers
What is a good PSI for a gas pressure washer?
A good PSI for a medium-duty gas pressure washer ranges between 2,000 to 3,200 PSI. This PSI range is generally fit to handle basic household tasks, such as pressure washing a driveway or deck. For commercial-level power, look for a gas pressure washer with 3,200-5,000 PSI.
Do all pressure washers use gas?
No, not all pressure washers use gas. Some pressure washers are electric models. Electric pressure washers are more portable, but they don’t have as much power as gas models. However, both types of power washers make suitable surface cleaners.
Why does my gas pressure washer need oil?
Oil keeps the engine lubricated, preventing it from wearing out. Two-stroke models mix the oil with the gas, but four-stroke models have a compartment just for gas.
What types of jobs can I use my gas pressure washer for?
Gas pressure washers have so much power that they’re really only safe for use on hard surfaces, such as concrete driveways and brick walls. If you use them on delicate surfaces, such as cars, you could cause irreversible damage.
