Product Reviews

We’ve spent hours researching real customer reviews, expert advice, and our own insight to create a comprehensive list of the seven best gas pressure washers on the market.

1. Simpson MegaShot 3100 PSI Pressure Washer

Best Gas Pressure Washer for Concrete

Gas pressure washers are the best power washing tool for concrete since concrete can handle very high water pressure. We recommend getting at least 3000 PSI for washing concrete, so this one from Simpson is an awesome choice.

With a residential engine from Honda, a 3200 PSI, and a 2.5 GPM, you won’t be disappointed with the cleaning power of this pressure washer. Take your concrete sidewalks, driveway, and garage floor from dirty to delightful in a super short space of time!

It works on other surfaces besides concrete. You can use this for cleaning bricks, vehicles, patios, garden furniture, and more.

What We Like

Top Tier Durability

This is no cheap product, so it’s great that it lasts for so long. The large fuel tank means that the pressure washer can run for a long time. The engine itself is sturdy, durable, and easy to operate.

The OEM technologies pump requires less maintenance and the crankcase does not require oil replacement. Last but not least, the hose is made of high-quality material, non-maring, and flexible which can handle all sorts of heavy-duty use.

Easy to Maneuver

Just one look at this device and you can tell it will be super easy to maneuver. It is very well balanced so won’t tip over when you push it. The large 10 inches wheels make it easy to navigate over a variety of terrains, too.

It Can Handle Almost Anything

Put this pressure washer to the test and see what it can do. It’s designed to remove dirt and mold so that you can say goodbye to nasty residue on surfaces. This includes siding, decks, garage floors, brick patios, and of course, concrete. You can also use it on vehicles, boats, RVs, outdoor furniture, lawn equipment, and grills.

What We Don't Like

May Be Too Strong for Some Jobs

3200 PSI is very strong. Sometimes this can be too strong for certain surfaces, even the ones that Simpson has approved. Just be sure to test in an inconspicuous area with the widest nozzle from a few feet away to check for evidence of damage.

Product Specs

GPM 2.5

2. Westinghouse WPX2700 Gas Pressure Washer

Best Durable Gas Pressure Washer

This is a very durable option that’s backed by thousands of happy customers. It’s a heavy-duty pressure washer with a long-lasting, maintenance-free axial cam pump which is designed to be durable and convenient.

A robust steel frame with abrasion-resistant materials also protects the main components. This frame is also very easy to clean, which will help to increase the lifespan.

If you’re looking for something to last a long time and never let you down — then this is one to consider. Plus, with a PSI of 2700, it can tackle most jobs without being too harsh on your surfaces.

What We Like

Onboard Soap Tank

It’s a good day when you find a gas pressure washer with an onboard soap tank! With the capacity of ½ gallon, this allows you to add detergent which can make cleaning a whole lot easier.

Intense Blast

This has an intense blast, especially when using the zero-degree nozzle, to help cut through grease, grime, and other stains.

Easy Transportation

This pressure washer is very easy to transport, thanks to the 12-inch never-flat wheels and the sturdy frame. Plus, the hose is abrasion resistant so even if it’s trailing on the ground, it won’t get damaged.

What We Don't Like

Overheats Easily

The engine can get hot and overheat. This can stop the pressure washer from operating until it’s cooled down, but it can also cause damage to the hose since the two elements are in contact. Overheating is usually caused by using on a hot day, leaving in the sun, or using it without breaks.

May Leak Oil

Quite a few customers noted that their pressure washer leaked oil. This normally happens pretty early on after buying the product, so you should notice this in time to get it fixed under the warranty.

3. Teande 4200PSI Gas Pressure Washer

Best Commercial Gas Pressure Washer

Do you need a pressure washer you can put to use in commercial areas? Maybe you have a building site to clean up, or a car business, or something else entirely. This is a top choice, in our opinion, since it’s durable, great for heavy-duty work, and has a high PSI of 4200.

Power is one of the big things to note about this pressure washer. Besides the high PSI, it has a super great GPM of 2.8. This is an amazing flow that will blast away stubborn stains, leaving you with super-satisfied customers.

When you’ve got many tasks at hand, you need something this efficient. The fuel can be burned completely so that you get 90 percent more cleaning power than an electric pressure washer.

What We Like

Five Quick Nozzle Tips

The more nozzle tips, the more versatile the pressure washer. This one comes with five: 0, 15, 25, 40 degrees and a soap nozzle. This allows the pressure washer to be used for a variety of tasks. Try cleaning homes, buildings, vehicles, boats, decks, driveways, patios, frames, and more.

Big Foam Spray Can

This pressure washer comes with an extra-large foam spray can. Add your favorite pressure washer detergent and you won’t run out for a long time. This allows you to do bigger jobs without interruption.

Works on Various Terrain

With the sturdy frame and large wheels, this is easy to move around even on tricky terrain. The 10-inch pneumatic wheels help out with maneuverability. So no matter where your client is based, you can bring this gas pressure washer with you.

What We Don't Like

PSI In Question

While many customers are perfectly happy, there are quite a few unsatisfied customers questioning the PSI. They say it doesn’t feel like 4200 PSI, but maybe somewhere around 3000.

4. A-iPower APW2700C Gas Powered Pressure Washer

Best Budget Gas Pressure Washer

This pressure washer has a PSI of 2700 making it great for use around the home. It’s designed for cleaning decks, sidewalks, patios, porches, driveways, vehicles, and siding. So you can get every job done with this awesome appliance.

What We Like

Lightweight and Portable

Weighing only 62.8 pounds, this is a pretty lightweight gas pressure washer. Plus, with the sturdy frame and large wheels, it’s very easy to maneuver this and take it where you need to.

25-Foot Hose

The long 25-foot hose gives you a lot of flexibility. It’s long enough to reach a range of spots without having to carry the main body with you.

On-Board Storage

This comes with onboard storage so you never need to get creative with how you store the nozzles, hose, cord, and other elements.

What We Don't Like

Hose Too Close to Engine

The hose is too close to the engine and exhaust. Since the engine and exhaust get really hot, this ends up being an issue and can damage the hose.

Turns Off When Moving

When you transport this pressure washer while it’s turned on, it often turns off. This isn’t ideal if you’re just trying to move the frame around your car.

5. Simpson Clean Machine Pressure Washer

Axial Cam Pump

The axial cam pump by OEM Technologies is a great feature to have on a pressure washer. It’s a maintenance-free pump, giving you one less thing to worry about.

What We Don't Like

Small Gas Tank

Some customers find the gas tank is too small. It runs for about 40 minutes before needing some more gas put into it. When you’re planning to spend your Saturday doing some deep outdoor cleaning, this can add to a lot of gas stops.

Watch Out for Leaks

Quite a few customers complained of leaks. Some had to do with the oil leaking from the engine. Other complaints had to do with leaks from the water inlets.

6. Generac 2900 PSI Pressure Washer

Best Portable Gas Pressure Washer

Many of our suggestions are nice and easy to transport since most are on wheels. Still, this is a top choice if you’re looking for a portable pressure washer. It is one of the lightest gas pressure washers on the market, weighing only 50 pounds. This makes it very easy to take with you as you deep clean your outdoor areas.

The frame is also economically built with a very sturdy outline, handle grip, and large wheels.

This comes with four quick-change nozzle tips. They’re easy to change over, making it super easy to switch them up depending on the task at hand. The options are 0 degrees, 25 degrees, 40 degrees, and soap.

What We Don't Like

Struggle to Get It Running

A lot of customers had trouble getting this thing up and running. Either it wouldn’t start upon arrival, or it would take a while. Customer service isn’t that great, so many customers had to solve the issue using their own money.

Not Very Durable

Some customers had this for a year before it stopped working; others were able to use it a couple of times. It’s not always the engine that gives out, too. The frame isn’t the most durable, the wheels can come loose, and sometimes the nozzles get misshapen and can no longer fit.

What Can You Clean with a Pressure Washer?

Wondering what jobs a gas pressure washer can handle? Here’s a list of some things you can clean with it:


You should always be careful when using a gas pressure washer as the PSI — or force — is much stronger than electric pressure washers. So you can cause damage more easily to more fragile surfaces such as furniture, vehicles, and siding.

Benefits of Gas Pressure Washers

When comparing gas and electric pressure washers, they both have their pros and cons. But let’s look at some of the awesome advantages of having a gas option.

  • They’re super powerful. The PSI is much higher on a gas pressure washer, making them super effective. This can speed up your cleaning time, clean better and help with stain removal.
  • You can use them residentially or commercially. These are heavy-duty appliances so if you want something you can use at home or at work, gas is the way to go.
  • Gas pressure washers have a higher water flow, which is rated at gallons per minute (GPM). This allows you to use much more force than an electric pressure washer.
  • They’re very durable. They’re made with higher quality parts due to the increased water pressure, so they often last longer.
  • They usually come on wheels. Although they’re heavier, they usually come in a very portable frame which can actually make maneuverability easier than an electric pressure washer that doesn’t come on wheels.

How to Choose a Gas Pressure Washer

If you’re liking the sound of a gas pressure washer, it might be time to buy one. Before you do, consider these important factors to help you choose the best one for your specific needs.


While you won’t find cordless or super lightweight gas pressure washers, you can still find ones that are more portable than others.

If you want something that’s easy to maneuver, we recommend getting something that’s in a sturdy frame on wheels. That way, you can easily move it from one place to another.


You should check what the pressure washer is made from. Not just the main body, but all the connecting parts, the hose, the pump, the frame, and everything else.

Weight and Ergonomics

Check how much the pressure washer weighs. The minimum will be around 50 pounds — so keep in mind these are heavy tools! But the ergonomics will make a difference. If it’s on wheels in a user-friendly frame, the weight shouldn’t be an issue.

Water Pressure

The water pressure is measured in PSI — pound per square inch. Most gas pressure washers start around 2700 PSI but tend to be in the 3000-4000 range. The higher this number, the more force the pressure washer will have.

You should also check the GPM — gallons per minute. This number reflects the amount of water that can come out of the unit. Again, the higher this number, the stronger the pressure.


Consider any safety precautions that the pressure washer has. This may include a child safety lock, automatic shut off or other cool features.


Gas pressure washers are an investment, but they do come in a range of prices. You probably won’t find something for under $200. Still, you can find quality pressure washers on the lower end of the price range for this tool.

Extra Features

What extra features does the pressure washer have? Does it come with any accessories, extra nozzles, an oil alert system? It’s worth checking this out so you know how much use you’ll get out of the pressure washer.


Last but not least, check the warranty to see how long the pressure washer is covered in case of damage, breakdowns, or accidents.

Choosing Gas

When you choose a gas pressure washer, you’re really taking the power up a notch. All of our choices are between 2400 and 3300 PSI, so they’re strong, powerful, and sturdy enough to handle the tasks at hand.

Whether you’re looking for something to use commercially or residentially, have we got options for you!

When shopping, just be sure to consider the main details: PSI, GPM, portability, weight, and of course, the warranty.
