Gas Powered
Pressure Washer 

A gas powered pressure washer will give you professional cleaning at a low DIY price. Since their prices have come down, there's no need to go to a rental shop and rent a gas washer for $50 to $95 a day!  

And you can check out my top gas pressure washer recommendation: the Generac 6596 on Amazon.

But how do you choose the best gas powered pressure washer to buy with you hard-earned money? Follow my tips to help you choose the best gas power washer for your budget and your cleaning jobs. You'll save time, money and frustration.

Let's quickly review how they work and then I'll share buying tips to help you choose the best power washer.

My #1 best gas washer recommendation is the Generac 6596 washer that's available on Amazon.

Hands-down, it's my top all-around best gas washer choice. It has a quality Generac engine, an axial cam pump you can count on and it'll give you 2,800 PSI and 2.5 GPM. This Generac gas pressure washer has the kind of power that will easily tackle any home or yard cleaning project you have.

And this Generac 6596 also has Never Flat tires, which I love. No more flat tire hassles!

You can check Amazons price on this recommended Generac 6596 pressure washer.

How a Gas Powered Pressure Washer Works

As you probably already know, a gas pressure washer is powered by a gasoline engine, not an electric motor.

After the gas power washer is hooked up to a garden hose to give it a water supply, the engine is started and the water flows to the pump through the unloader valve.

The pump quickly pressurizes the water and forces it up the high pressure hose, through the spray wand, to the spray gun. When the trigger is pulled on the spray gun, the water is forced through a spray nozzle.

When the pressurized water exits from the spray nozzle tip, the water stream is up to 60 times the PSI (Pounds per Square Inch) of the water pressure coming out of the garden hose.

It's the great force of this water that gives gas powered pressure washers the ability to clean better than a garden hose and more quickly than a scrub brush!

Generally speaking, gas powered pressure washers have about twice the cleaning power (PSI) than an electric unit.

Buying Tips

If you're thinking about buying a gas powered pressure washer, there are a few important things you need to keep in mind to pick the best one for you.

You can expect to spend about $300 to $650 for a good quality unit that's typically sold to homeowners.

(If you're not entirely sure you need an electric or gas pressure washer, you can read my Gas versus Electric Pressure Washer page, to help you make the choice.)

Let's go through my buying checklist:

1. When you shop around for gas pressure washers, check out the engine on each unit!

You can find units with "no-name" engines or brand names engines like Honda, Kohler, Briggs & Stratton, etc.

You'll notice that you'll probably pay a few more dollars for a unit with a well-known brand name engine. It's your choice, of course, but I've found that I get better & longer performance with a brand name engine (I have Honda). And good warranty coverage in case anything goes wrong.

2. Take note of the gas pressure washer pump too!  

It's easy to forget as you shop, but remember that the quality of the pump is just as important as the quality of the washer engine. The pump is the beating heart of the washer and it's puts the pressure (cleaning power) in the water.

There are axial cam pumps and triplex pumps. The axial cam pumps are the best suited for homeowners and the triplex pumps are geared for contractors.

You'll see no-name axial pumps & brand name pumps on gas pressure washers. Again, you'll probably spend a few more bucks for a Comet, CAT, General, AR or Briggs & Stratton pump. But you'll get better warranty protection.

3. - And you'll want to compare the ratings too.

There are two basic gas pressure washer ratings that you need to keep in mind so that you can accurately compare models:

PSI or Pounds Per Square Inch is the force that the washer is able to produce. I recommend choosing a gas pressure washer with a minimum of 3,000 PSI.

GPM or Gallons per Minute is the rate of the water flow.

That's it! Armed with these gas buying tips, you'll be able to compare & buy the best unit for you!
