How We Picked the Best Gas Pressure Washers

When recommending gas pressure washers, we take four features into account.†

Durability

From getting knocked, tipped over, or otherwise manhandled, gas pressure washers can sure take a beating, especially on job sites. Beyond this, frequent use can put a strain on the engine, pump, and other internal components. Thatís why I only recommend units that can take a few punches and still perform time after time.†

Durability starts with the frame. The material, thickness, and number of welding points all play a role in how much abuse the pressure washer can handle. For example, frames made from aircraft grade aluminum are much desired for their strength yet light weight. †

I also consider the tires. Can they handle rough terrain? Not every property will be flat and uncluttered. How do they resist ďwalking,Ē which is unwanted movement caused by engine vibrations? The hose should be kink-resistant because, letís face it, we all abuse hoses.†

Finally, I look at the engine and pump. Is it a reputable brand? Does it run cool? Will it handle years of use? Every component should be built to last.†

Usability

Using your pressure washer should be as simple and frictionless as possible. This is where I look at anything that makes life easier for you, the user. †

Letís start with the basics. For a portable gas pressure washer, how portable is it? How much does it weigh? Can it handle rough terrain? Some units have onboard storage for the spray gun and hose, which is a plus.

I also look for usability features like electric start, which will get you washing in a jiffy, ergonomic components, and quick-connect fittings that help you easily switch attachments. Safety and comfort features, like low oil shutoff and temperature sensors, are another consideration.

Versatility

You can wash almost anything with a pressure washer. Thatís why the best gas pressure washers are versatile in the sense that you can adapt them to your application. Iíve already mentioned the importance of quick-connect fittings, but it goes beyond that.†

From telescoping wands for high places, to surface cleaners for your deck, there are many attachments and accessories. The best gas pressure washers either come in a kit with some of these or can at least accommodate them. †

Another important versatility feature is adjustable pressure. If you used the same water pressure for cleaning your car as for your driveway, you would quickly need a new paint job. Adjustable pressure lets you suit the washer to the task at hand. For those wanting to use soap, a pressure washer with siphon tube injection capability makes it simpler than adding soap manually. Overall, anything that expands the way you can use your pressure washer earns extra points from me.

Overall Value

You get what you pay for. Sure, there are cases when you can get a great deal on a quality pressure washer, but it usually costs money and resources for manufacturers to make their product ďthe best.Ē†

Thatís why I donít exclusively consider price when determining value. Itís a factor, but not the most important one. I'm most interested in whether the pressure washer is worth the price. Do its durability, usability, and versatility features justify the purchase? This is also where I consider the warranty and where the pressure washer is made.

Professionals who want the durability and easy maintenance of a belt drive pressure washer should look no further than the Pressure Pro EB4040HC-20.

Gas Pressure Washer FAQs†

What is GPM?

GPM stands for Gallons per Minute and describes "how much" water is produced, or its volume. A pressure washer rated for 4 GPM can produce 4 cubic feet of pressurized water per minute.†

What is PSI?

PSI stands for Pounds per Square Inch and describes the pressure, or force, of water. A pressure washer rated for 1,000 PSI can produce 1,000 pounds of water per square inch.

How Does GPM Relate to PSI?

In the pressure washer world, we multiply a unit's PSI (pressure) and GPM (flow rate) to arrive at cleaning units, which refers to cleaning speed. For example, if two washers produce the same water pressure, but one has a higher flow rate, it will clean faster than the other.†

What PSI pressure washer do I need?†

It depends on what you want to wash. PSI stands for pounds per square inch and represents the water pressure. Most homeowners will be satisfied with a 1,000-4,000 PSI pressure washer. The higher the pressure, the heavier the dirt youíll be able to clean, like garage floor stains, paint splotches, and thick mold. Lower PSI pressure washers are perfect for lighter cleaning, like car washes, cobwebs, and your grill. Heavy-duty commercial pressure washing jobs will require more than 4,000 PSI.†

The best pressure washers come with an adjustable PSI setting, so you can adapt the pressure to your application. Learn more about selecting the right PSI pressure washer in our pressure washer buyerís guide.

Can you run a pressure washer without water?†

Never run your pressure washer when itís not connected to a water source. The motor and pump need water flowing to stay cool. Without that flow, theyíll overheat and fail prematurely, forcing you to buy a new pressure washer.†

Whatís more, avoid leaving your pressure washer on when not squeezing the trigger. Pressure will build up inside the pump and hose, leading to overheating and excessive wear and tear. Although some of the best pressure washers have bypass capability that helps circulate water and delay overheating and/or a thermal relief valve, this has its limits. †

In short, always be running water through your pressure washer and gun. If you need to stop working, turn off the engine!†
