10 Best Gas Pressure Washers - Reviews
1. SIMPSON Cleaning MS60763-S Gas Pressure Washer- Best Overall Pick
Overall, this is the best gas pressure washer we've found. The Simpson MS60763-S MegaShot includes everything you might want from a home pressure washer. It has sturdy steel frame construction on a steel frame that allows easy access for maintenance while still retaining strength and durability. Its 12-inch wheels never need air and are wide enough to get around quickly on most surfaces.
At 3100 PSI, it’s strong enough for every home maintenance job you can think of, including paint stripping if that’s required. The Simpson includes five quick-connect attachments, so you won’t have to fumble with clunky connectors. And, it has a safety lock feature on the trigger so it won’t go off unexpectedly, which can be dangerous at the pressures involved.
It comes with a two-year warranty in case you have trouble with it.
2. SIMPSON Cleaning CM60912 Gas Pressure Washer- Best for the Money
It’s telling that Simpson makes two of our top three gas powered pressure washers. The Simpson CM60912 is a robust, upright, gas-powered pressure washer, more in keeping with home and garden use than some of the more powerful pressure washers in our top ten. It comes with three quick-change nozzle tips attachments, an onboard soap tank, and a 25-foot long high-pressure hose.
At 2400 PSI, the Simpson gas pressure washer has enough power for almost anything you need to do around the house, while not having so much that you need to worry about injury. Its upright design is unique for a gas pressure washer, and it allows it to maneuver more like an electric washer, though balancing the big engine may require some adjustment. With the upright design and comparative light weight, you’ll have more storage options.
The Simpson Cleaning CM60912 provides you with many of the features you expect from a gas pressure washer, at a price comparable to a high-end electric washer. It sacrifices little power while making it easier and more accessible for the casual user. If you want the weight and ease of an electric, but the mobility of a gas pressure washer, this is the perfect pressure washer.
3. DEWALT DH4240B Gas Pressure Washer - Premium Choice
If you’re willing to spend the money, our premium choice is the DeWalt DH4240B. This monster is a commercial-grade unit and comes with five interchangeable quick-connect attachments for a variety of uses, including an attachment designed for spraying soap. It’s made from a steel frame, making it incredibly durable and stable. And, it sits comfortably on wide 13-inch dual-sealed wheels that will never go flat.
Dewalt is known for power tools, and this is no exception. At 4200 PSI, it’s one of the most potent pressure washers available for home use. Its 50 feet of hose affords one of the most extensive operable ranges on our list. Treat it with caution, respect, and intelligence, or you may create serious accidents.
The DeWalt DH42408 gas pressure washer also comes with a 3-year warranty, which is better than most competitors and will keep this unit running for a long time. It is, however, both expensive and quite loud.
4. Pressure Pro E3027HC Gas Pressure Washer
The Pressure Pro E3027HC is at the other end of the cost spectrum from our most economical pick. Like the DeWalt above, this gas pressure washer is more of a professional model in some ways. But, unlike the DeWalt, it is much lighter, being made from a sturdy aluminum alloy rather than steel. This makes it more agile and less of a chore to move around.
While it doesn’t overwhelm with fancy new features, there are a few notable things to make the Pressure Pro interesting. For starters, it has a 50-foot hose, which gives it more range in addition to being light and maneuverable. The Pressure Pro gas powered pressure washer also includes a mesh inlet that covers parts of the engine to prevent detritus and dirt from ending up in your motor (resulting in expensive maintenance).
Like many of its competitors, the Pressure Pro comes with an assortment of quick-change nozzle tips.
5. Powerstroke PS80544B Gas Pressure Washer
The Powerstroke PS80544B looks like a juggernaut of a pressure washer. But, it’s a reasonably priced alternative with a lot of power and some terrific features. Like many of its competitors, it comes equipped with four of the most common quick-change nozzle attachments. But, it adds an onboard soap tank that automatically mixes soap with the spray rather than requiring a separate soap container.
At 3000 PSI and 2.5 gallons per minute, this gas powered pressure washer has a lot of power available for comparatively little cost. Additionally, it provides onboard storage for all of its attachments, which keeps everything conveniently at hand. The large Tread Cap wheels offer easy mobility and a steady grip on even rough terrain where other tires may slip.
The Powerstroke gas pressure washer is a terrific pressure washer for its price, but some customers have complained that it isn’t as durable as they’d like. However, it does come with a two-year limited warranty if you have problems.
6. WEN PW3100 Gas Pressure Washer
Another excellent gas pressure washer for its price is the WEN PW3100. It blasts grime, paint, and stains at a very respectable force of 3100 PSI using 2.5 Gallons per minute, which is well in line with some more expensive products. In fact, the WEN is a talented gas pressure washer for the price of a high-end electric.
The WEN Pressure washer includes everything you would expect from a much more robust pressure washer, such as five quick-connect nozzle tips (included), an onboard soap tank, hose storage, and a two-year warranty. Its 30-foot hose is slightly larger than average, though, which gives it an excellent range of mobility on its robust 12-inch wheels.
However, there are a few issues with its construction that shouldn’t go overlooked. Customers report that the wheels are often loose, which can make the unit unsteady over rough terrain. Also, the axial cam pump on the engine requires users to be cautious with oil intake and to follow the instructions correctly if they want to avoid costly maintenance issues and repairs.
7. Generac SpeedWash 7122 Gas Pressure Washer
The moderately expensive Generac Speedwash 7122 is an impressive pressure washer with plenty of power to do almost any cleaning job without breaking the bank. With its unique pressure dial, users can automatically change the pressure according to the type of job they have in mind, making pressure washing user-friendly and intuitive without swapping nozzle heads. The pressure dial helps this washer take some of the guesswork out of washing more delicate material.
Generac has included several specialized nozzle heads, such as a turbo nozzle for tough dirt and grime and a power broom for quick horizontal surface cleaning. It also comes with a quick-change soap blaster that draws directly from an onboard soap tank. And the 30-foot hose is longer than some of its competitors, giving added range while still being rugged enough to handle abuse.
This pressure washer comes with a two-year limited warranty, which is good since some customers complain that it isn’t as durable as they’d like.
8. Duromax XP3100PWT Gas Pressure Washer
The Duromax XP3100WT provides 3100 PSI at 2.5 GPM, which is pretty powerful for its price range. Duromax includes six quick-change nozzle heads rather than the standard four that comes with most of its competitor's models. But, customers complain of cheap plastic construction on some key components, and that it requires regular engine maintenance.
Like others in its class, it has onboard hose storage for its 25-foot hose, and a built-in soap tank for convenient use. This pressure washer includes a Low Oil Shutdown feature, so you don’t risk damaging the engine when oil levels get low. And you may need it, as customers report that the oil on the Duromax XP needs regular attention.
9. Ford FPWG3100H-J Gas Pressure Washer
Much like the DeWalt pressure washer above, Stanley produces quality craftsmanship across a wide range of power equipment and tools, and their pressure washer is no exception. They’ve built a durable powder-coated steel frame to carry a powerful 196cc engine on sturdy 12-inch wheels. They've designed the motor to start quickly and efficiently, but it may still require more oil-level monitoring and regular maintenance than casual users are willing to provide.
Stanley offers a turbo nozzle with this unit as well as four spray nozzle attachments, but there isn't an onboard soap tank included, so you may need to buy an after-market soap sprayer. It does provide an adjustable pressure regulator on the wand. Simply twist the nozzle to moderate the amount of pressure for lighter tasks or more delicate materials.
10. STANLEY SXPW3124 Gas Pressure Washer
Ford may not be the first name you think of when considering power washers, but they’ve built a very nice unit that provides excellent pressure at high GPM, meaning you’ll get everything as clean as it can get. The padded, folding grip makes this pressure washer easy to store and comfortable to move when in use. Like many of its competitors, Ford has included an onboard soap tank to quickly lather down any surface.
The Ford’s 30-foot hose is longer than several of its competitors, giving it extra reach for complicated jobs. Its frame, made of durable steel construction, has brass connectors in critical areas, which provide longevity and a more stable connection for the hose storage and attachments. This pressure washer also comes with four standard quick-change nozzle heads and a low engine bed, making it very stable on any surface.
Final Verdict: Our Overall Winner
SIMPSON MS60763-S MegaShot
When investing in a gas pressure washer, you likely already know why you need it. Gas pressure washers are the more mobile, more powerful version of their electric kin. As such, care should be taken that their power doesn’t damage the surface you’re trying to clean.
For anything but professional cleaning jobs, we like the Simpson MS60763-S MegaShot. It has all the power you need to get the job done, but it’s sufficiently variable to adjust between light and medium applications. It’s just light enough and powerful enough, with all the right features to make it the best gas pressure washer for any situation.
Buyer’s Guide: Find the Perfect Gas Pressure Washer for YOU!
Facts under High Pressure
Almost everyone has put their thumb over the nozzle of a garden hose to clean their car. Or, you may have used a dishwashing sprayer to blast grime from your cookware. By the same principles of physics, pressure washers accelerate water (with a lot more force) by using either an electric or gas-powered pump.
Water under pressure is capable of carving out the Grand Canyon or scouring dirt and mold from your home’s siding. Add a little detergent or soap to the water and it gets even better. All pressure washers work by directing concentrated water against stubborn stains to dislodge dirt and lift it away.
But some pressure washers work better than others.
What kind of Pressure Washer is right for me?
There are two main types of pressure washers on the market today: gas and electric. Within those two broad categories there are hundreds of styles to choose from. To determine which type of washer is right for you, first think about what you’re going to do with it, paying close attention to the surfaces you want to clean.
Gas pressure washers generally have a much higher pounds per square inch rating than their electric counterparts. A higher PSI rating means water hits the surface (the surface you are cleaning) harder. If you have ground in oil stains in the driveway or stubborn mold on your siding, you may need a lot of power. But, a higher PSI isn’t always a good thing, as it can also scour paint from walls, strip stain from wood, or damage porous surfaces.
Electric pressure washers, unlike gas-powered, are tethered to a direct output source, so they’re less maneuverable than their counterparts. They’re excellent for general home and garden uses such as washing your car or cleaning dirt from your driveway, patio furniture or deck. And electric pressure washers with a high PSI can still sometimes unintentionally strip paint if the user isn't careful.
Things to look for in a Pressure Washer
As we’ve mentioned, the first consideration in buying a pressure washer should be its PSI. Higher PSI may be excessive in some instances and cause damage to the surface you’re trying to clean. Unfortunately, most gas pressure washers have PSI high enough to harm materials (and people) if you’re not careful, which is why looking for one with an adjustable pressure gauge or variable nozzles is essential.
Gas pressure washers can be bulky and heavy, which is tolerable for industrial applications, but it makes them unwieldy for simple jobs around the house. Figure out what you need the pressure washer to do and how important mobility is for the task at hand. Remember that power outlets aren't always conveniently placed on your home's exterior.
Gas washers make doing big jobs more manageable, and you probably have big projects in mind if you’re thinking of buying one. If you're only washing the dirt off your patio, or occasionally washing your car, you should find a more modest, quieter electric unit that is less expensive and still does the required job.
A Few Words of Caution
Pressure washers, particularly heavy-duty gas-powered ones, aren't toys and shouldn’t be treated as such. 3000 PSI of water may not sound like much, but that kind of power can damage certain surfaces like sandstone, brick mortice . . . and skin. Always use eye protection when using a pressure washer and never aim it at another person.
As we’ve mentioned, high PSI can damage surfaces and is often used to strip paint. Read the instruction manual for any unit you purchase, and be cautious of the surfaces you’re trying to wash. Sandstone, old brick mortar, and asphalt ceiling tiles are terrible surfaces for high-pressure water as they can disintegrate quickly, causing serious damage.
Gas pressure washers also involve engines, which means you’ll often need to make sure your motor has a steady oil supply and fuel. Luckily, engine maintenance is usually covered in the user manual and can be supplemented by qualified mechanics when necessary.
