Carry on reading to see our full list of the best gas pressure washer, followed by a recap breaking down what makes each product on our list stand out. Or jump straight to our number #1 pick on Amazon here.

What Should You Look For in a Gas Pressure Washer?

If you’re new to the world of gas pressure washers, you may feel overwhelmed looking at all of the different products. It can be dizzying, to say the least, to have to decide among so many options when you’re not an expert and maybe don’t even know what separates the good gas pressure washers from the bad ones. Not to worry though, we’re going to list out the criteria we used to assess our products so that you can stay in the loop and feel ready for what lies ahead. You’ll feel like an expert in no time, and you’ll be able to follow along with our list. You’ll even be able to conduct your own further research if you so desire.

Criteria #1: Pressure – I don’t think it will surprise anyone that a pressure washer, gas or otherwise, needs, well…pressure. Pressure is measured in pounds per square inch (PSI), and the more PSI, the stronger the blast of water from your pressure washer will be. This will lead to that hyper-satisfying YouTube-worthy sight of the dust and dirt washing away off of your belongings before your eyes. In general, gas pressure washers pack a bigger punch than electric pressure washers, and we want to make sure that our list only includes the strongest of the strong.

Criteria #2: Output Volume – There’s more to a quick and efficient clean than just a lot of water pressure. The amount of water you’re using is just as important as its pressure, which is why we need to look for pressure washers that have a high GPM (gallons per minute) rate as well as a high PSI. A high GPM will help you cover more ground and is particularly useful if you have more space to clean. So if your concern is just as much quantity as it is quality, look for a gas pressure washer with a high GPM.

Criteria #3: Weight – Right away I’ll mention that the unfortunate truth is that all gas pressure washers are pretty darn heavy – much heavier than electric pressure washers. But, of course, everything is part of a spectrum, and we can still try and find the lightest options out there so you don’t have to lug around a massive machine all day and throw your back out trying to clean your driveway.

There is the unfortunate trade-off that horsepower and size will usually go hand-in-hand. In most cases, I’ll give the priority to the stronger machine, but there are the hidden gems that manage to fit a lot of strength into a light build. Besides that, I’ll make sure to include at least one lighter option for those who really can’t be bothered to deal with a massive, heavy machine.

Criteria #4: Price – We’re not here to make you spend a ton of money for no reason. Meeting this criterion is less about being cheap and more about justifying your price. We’d rather buy an expensive product that’s cheaper than it should be than waste money on a cheaper product that isn’t worth the money and that will just break on you or not perform well. Gas pressure washers are more expensive on average than electric washers, but we’ll try to mitigate the damage as much as possible and show you the cheapest options and the ones that offer the biggest return on your dollar.

How Does a Gas Washer Compare with an Electric?

I’ve already made the comparison between gas pressure washers and electric pressure washers a few times in passing, but I’ll lay it all out here so you can have the information in a more comprehensive manner.

To start, gas washers are unfortunately a fair amount more expensive than electric washers. Of course, the benefit that comes with that is a machine that’s much stronger than one that runs on electricity. While electric pressure washers will usually have a PSI somewhere in the range of 1,000-2,000, even the cheaper gas washers are all but guaranteed to have a PSI above 2,000.

Similarly, the standard rate of gallons per minute for an electric washer is 1.2, while a gas-powered pressure washer will most likely have a GPM of 2.5 or even higher.

Another drawback of these heavy-duty pressure cleaners is that they’re fairly heavy. While an electric pressure washer will weigh between 15 and 30 pounds, a gas-powered washer will easily weigh more than 50 pounds.

Finally, there’s the environmental factor. If you want to reduce your carbon footprint, then an electric pressure washer is the only way to go.

I should mention that the reality is, most customers will be more than satisfied with an electric pressure washer for their daily residential cleaning needs. But if you have a four-wheeler or an offroader that’s going to get particularly dirty fairly often, or if you need an extra-strong pressure washer to make a living, then a gas-powered pressure washer is definitely the right choice for you.

Here’s How We’ve Determined the Best Gas Pressure Washer

#2: Ryobi 3000 PSI 2.3-GPM Honda Gas Pressure Washer (Best Overall Gas Pressure Washer)

With the Champion 2600-PSI 2.2-GPM Dolly-Style Gas Pressure Washer, we’ve introduced you to the best deal on the market. But what if you don’t want the best deal? What if you’re willing to pass on a good deal if it means finding the best overall product? Well, if that’s the case, we’ve got you covered. For those that are willing to splurge for the best and won’t settle for anything else, then you can stop looking because the Ryobi 3000 PSI 2.3-GPM Honda Gas Pressure Washer is the only pressure washer for you.

It’s a bit more expensive than our top-ranked Champion gas-powered pressure washer, but it’s just about the best gas-powered pressure washer out there. Here are a few reasons you may decide to skip on the Champion 2600-PSI pressure washer and give your hard-earned cash to the Ryobi 3000 PSI 2.3-GPM Honda Gas Pressure Washer.

Reason #1 to Choose This Product: All of the PSI

The numbers don’t lie, and our first selling point for this Ryobi Honda-powered pressure washer is as simple as it is convincing. The Ryobi 3000 PSI 2.3-GPM Honda Gas Pressure Washer boasts an out-of-this-world water pressure of 3,000 PSI. Compare that to the 1,500 PSI found in most electric pressure washers and you’ll get some solid perspective on how much pressure that is. Even compared to the 2,600 PSI of our number one gas washer, the cleaning power of our Ryobi pressure washer is just off the charts. That pressure is enough to blast your door down.

With 2.3 GPM, the Ryobi 3000 PSI 2.3-GPM Honda Gas Pressure Washer even has (marginally) better water flow than the Champion 2600-PSI 2.2-GPM Dolly-Style Gas Pressure Washer, so there’s really just no contest. Of course, a lot of customers simply don’t need that kind of pressure, but if you’re going to be doing some awfully serious cleaning outside and you want to speed that process up by pulling out all the stops, there’s just no choice for you but the Ryobi 3000 PSI 2.3-GPM Honda Gas Pressure Washer.

Reason #2 to Choose This Product: 5-in-1 Nozzle

On top of the insane water pressure and above-average water flow combining to give you the best raw cleaning power out there, our high-powered Ryobi pressure washer features a 5-in-1 nozzle that will let you stay ready for whatever comes your way. This nozzle features a quick-change design that will let you smoothly switch out the head on the nozzle so you can stay flexible and use the exact attachment that’s perfect for your current situation. So whether you want to turn down the intensity a bit, need more soap, or want to use a specific head depending on what you’re cleaning, the Ryobi 3000-PSI high-power pressure washer has you covered. Stay on top of everything with our overall best pressure washer.

On top of the quick-change, 5-in-1 nozzle and the completely insane water pressure, the Ryobi 3000 PSI 2.3-GPM Honda Gas Pressure Washer features a powerful Honda premium GCV160 engine, an on-board detergent tank for easy soap application, and an extra-long 35-foot hose that Ryobi promises will offer a 40% longer reach. This pressure washer also comes equipped with large 12-inch wheels that will keep transportation of this relatively light 56-pound washer as easy as possible.

Just as with our top pressure washer, this Ryobi product featured on multiple lists and articles of the best pressure washers, and it has plenty of love from the customers. Ryobi is one of the most trusted brands out there for all types of pressure washers, so right away you know you can rest easy.

As we mentioned, this product is more expensive than the Ryobi 3000 PSI 2.3-GPM Honda Gas Pressure Washer, but it’s still a pretty solid value, and it can’t be beat in terms of specs. If you don’t like to cut any corners, splurge for the Ryobi 3000 PSI 2.3-GPM Honda Gas Pressure Washer.

#3: Briggs & Stratton S2200 2200 MAX PSI at 1.9 GPM Gas Pressure Washer (Best Lightweight Option)

Right off the bat, I will have to admit that “lightweight” is a relative term in this instance, and it’s hard to find a gas-powered pressure washer that’s small. Now that that’s out of the way, if you want to keep things as light as possible, but you still need the raw cleaning power that only a heavy-duty gas-powered pressure washer can offer, then the Briggs & Stratton S2200 2200 MAX PSI at 1.9 GPM Gas Pressure Washer is the only pressure washer for you.

Weighing “only” 50 pounds, the Briggs & Stratton S2200 2200 MAX PSI at 1.9 GPM Gas Pressure Washer is just about the lightest gas washer out there, and it also features an ergonomic design with large 10-inch wheels that will aid in transportation.

Admittedly, there is a clear trade-off for the convenience of a smaller product, as our 3rd gas-powered pressure washer features a somewhat sub-par PSI of 2200 and a relatively low GPM rate of 1.9. To be clear, the pressure and water flow of this machine are still much better than those of any electric pressure washer, and it’ll meet the needs of almost any typical customer who’s using their washer for domestic purposes.

In addition to its amazing and compact design, the Briggs & Stratton S2200 2200 MAX PSI at 1.9 GPM Gas Pressure Washer features a 3-head quick-change nozzle, effortless starting thanks to its maintenance-free axial cam pump with Easy Start technology, and a 25-foot long hose that will help you easily each any stain that was too far away to drag this lightweight pressure washer close to.

Be warned, this Briggs & Stratton gas-powered pressure washer is the most expensive pressure washer on our list so far, so if you need to save money, this is not the choice for you. And if you want the small size but need to cut back on costs, you might be better off going with an electric pressure washer for your outdoor cleaning. But if need a true mighty mouse and you’re willing to pay for it, this is the choice for you.

If you just don’t have the capacity to deal with a 100-pound pressure washer, then make your Sunday chores a little less tedious with the small-but-powerful Briggs & Stratton S2200 2200 MAX PSI at 1.9 GPM Gas Pressure Washer.

#4: Westinghouse Outdoor Power Equipment WPX2700 Gas Powered Pressure Washer (Best Low Cost)

Our previous three gas pressure washers have been pretty expensive, so if you need to stay within a tight budget, you may be starting to feel out of the loop. But don’t worry, there’s always an affordable option to be found if you know where to look. It’s amazing the Westinghouse Outdoor Power Equipment WPX2700 Gas Powered Pressure Washer manages to be so cheap.

In terms of water flow and strength, it’s right up there with the rest of the crowd with a PSI of 2,700 and a GPM of 2.3. This Westinghouse pressure washer also comes with a 1-gallon gas tank and a built-in soap tank. It’s “protected by robust steel framing and abrasion-resistant materials for dependable cleaning.” Even for a gas-powered pressure washer, the Westinghouse Outdoor Power Equipment WPX2700 Gas Powered Pressure Washer is on the heavier end of the spectrum with a weight of 63 pounds, though it’s still slightly lighter than our top-ranked pick from Champion.

Our budget gas pressure washer comes with a 4-way, quick-change nozzle with options for 0°, 25°, 40°, and soap, so you can clean everything at once or zero in on one spot. Westinghouse boasts that this gas washer features “never-flat wheels” that “provide easy transportation and maneuverability.” It also features a 25-foot hose that will give you plenty of room to move around.

#5: Generac Gas Pressure Washer 3100 PSI 2.5 GPM Lithium-Ion Electric Start with PowerDial Spray Gun (Most Flexible Option)

It’s also one of the more expensive options, and your wallet will definitely feel the hit it takes from purchasing this pressure washer. But its versatility is just one of a kind.
