The Best Generac Power Washer

Here’s an in-depth look at the best gas powered Generac pressure washer for the money (and the runner-up). You’ll also learn startling facts about Generac, the company. And some pressure washer features their customers want them to improve.


Generac pressure washer intro imageDid you know Generac pressure washers are not made in China?

(Not that there’s anything wrong with Chinese manufacturing, I mean, all iPhones and most electronics are made in China)

But yeah, Generac has manufacturing facilities in 8 different locations – 5 in Wisconsin, 1 in Italy, 1 in Mexico and 1 in Brazil – totalling 3 million square-foot of space, which is equal to an average of 6.5 football fields each.

Generac (and AR Blue Clean) is unique because they have in-house engineering/design and manufacture teams for their pressure washer gas engines and pumps. This allows them total control over the specs and features of each model.

Now the surprising fact: Briggs & Stratton portable generators and power washers are engineered by Generac. Follow this timeline of events to see how that fact can be true:

  • 1998 – Generac sells off their portable products division to Beacon Group, which included portable generators, power washers and water pumps
  • 2000 – Beacon sells it to Briggs & Stratton who then starts selling those generators and power washers with Briggs branding.
  • 2008 – Generac’s 10-year non-compete agreement expires and they re-enter the portable generator market
  • 2011 – Generac re-enters power washer market.

Did Generac go out of business during these 10 years? No. They fortified their home, commercial and industrial standby/backup generator business. To this day that is their core revenue stream.

Now, at last, let’s look at what Generac pressure washer is best for most people:

Best Generac Gas Pressure Washer For Most People 

1) Generac 6596 2,800 PSI 2.5 GPM Gas Power Washer

Generac 6596 2800 PSI Gas Powered Residential Pressure CleanerThe best Generac for most people is the top-range 2,800 PSI medium duty you see pictured.

It’s about 1.5 – 2x the price of other electric medium-duty pressure washers… But you get the extra power and flow to easily complete big driveways in 1 hour instead of 3.

Using the 40-degree “wash” nozzle at the correct distance you can also safely wash you car. People like the big wheels and upright stance of the unit because it makes it easy to move around during or between jobs.

So why is this the best Generac for most?

It’s The Best Deal – Let’s be honest: in terms of choosing within a certain brand you’re looking for the best deal – the most power for the least price. This model is that…

…It has 22% more cleaning power for only 7% more money (Generac’s suggested retail price) of the model below. And the model above this one is 33.4% more money (Generac’s suggested retail price) but only 19.6% more cleaning power. The reason for that big jump in price is the jump from medium to heavy-duty pressure. With the higher pressure comes a larger engine.

So if you want to make quick work of your driveway, deck, garage floor, fence, back patio… Here is one of the most affordable gas powered pressure washers – given the durability of a gas engine, you can pretty much guarantee this machine will last you close to 10 years with proper care.

A Suitable Alternative That Has Adjustable Pressure

2) Generac OneWash

Generac 6602 3100 PSI Gas Pressure WasherDo you want adjustable pressure at the turn of a dial?

Pressure is the force over an area. You can easily adjust the water force the surface feels by increasing the area between the nozzle and the surface. You do this without thinking. It’s also what the nozzles are for – they disperse the water over a larger area decreasing the force the surface feels.

So what’s the point of a pressure washer with a dial to adjust the pressure when you can just do it by adjusting distances and nozzles? I’m glad you asked.

Here’s Generac’s recommended pressure chart. With a variable pressure dial you don’t have to do any math or guess work trying to figure out how far you should hold it from the surface… You can just turn the dial. It removes guess work from the equation.

Generac Pressure Washer Recommended Uses

The OneWash has 4 settings between 2,000 and 3,100 PSI. It is effectively 4 pressure washers in 1. You can go from vehicle washing to blasting oil stains from your driveway at the turn of a dial. So if you are willing to spend about $100 more than the #1 choice for the variability (and extra cleaning power) then get it while it has free shipping.

How Your Life Will Improve With A Generac Pressure Washer

Driveway Cleaning With Pressure Washer


Effortless, Satisfying Cleaning – Ask anyone who owns a power washer and they’ll tell you how easy it is to clean surfaces around the house. All you have to do is roll the unit out of the garage or shed, screw in the garden hose, start up the machine and get cleaning. Many people even get excited to use their pressure washer – it’s a little like a sport, in a way. You have a the gun and lance to point and shoot the dirt, grime and grease away. It’s oddly satisfying seeing the dirt wash away.

Save Money Next Water Bill – You use much less water with a pressure washer than with a garden hose. The Generac’s above use 3x less. Water might be affordable in your area, but still, what you save in water can go towards the petrol bill.

Cool Tool – Pressure washers stand out amongst power equipment because you can physically do something with them. A generator is cool but it is more of a supporting tool than a primary one. Everyone should have a pressure cleaner around their house. Their affordable, useful and fun to use.

You Can’t Please Everyone (Constructive Reviews)

Here’s 2 constructive reviews that suggest purchasing a better hose and a surface cleaner. After each review I give my thoughts on the matter.

“Cheap, poor hose – upgrade hose and its pretty good”

Review by Joseph M. Baltrus Ph.D. (Vicenza, Italy) on

My very first use, the hose kinked in 4 places and burst immediately. Talk about heart broken. Generac is replacing it, no questions asked but come on now. […] The plastic once bent or kinked retains the fold and makes for a instant weak point in the hose. I “upgraded” to a non-kinking hose for additional 22 bucks but technically no one should have to do that, let alone have their new 279 dollar washer break on first use. The rest of generator is fine, its starts on 3 pulls on average and you have to learn to use the choke to idle the engine correctly. […] A 25 foot hose length is non-issue so don’t listen to others that tell ya its too short or you need a 50 foot hose, its gas powered so you are free to move around as much as you need.

So if you decide on this washer (mainly because of the price to specs) its fine, just know to buy better non-kinking hose too so you don’t go through what I went through.

My thoughts: I would agree on advising you to buy the non-kinking hose. Yes, it sucks that that hose isn’t the one included. But nothing is worse than a crappy hose.

“…Really need to buy the attachment that makes it easy to clean long driveways”

Review by Amazon Customer “Old Corps” (Wilmington, NC)

You really need to buy the attachment that makes it easy to clean long driveways. The pressure of this unit is good and for small jobs this is adequate. Look at the Yamaha attachment that you can buy that goes on the wand and read the reviews of it.

Yamaha 15 Inch Surface CleanerMy thoughts: What Old Corps is talking about is a surface cleaner. You connect the lance to the surface cleaner and it distributes the spray evenly over a larger area making quicker work of the driveway. The Yamaha one pictured right is $75.


A great reason to buy a Generac is because they design and manufacture their own engines and pumps. This means they controls the quality A-Z. No faulty kit makes into the distribution warehouse.

Also, with their tight-knit team they can listen and respond to feedback from customers very quickly. That is how they have improved their pressure washers year-after-year.

  1. Generac’s Investor Relations SEC Filings page was used to find the most recent Annual Report 2014. Reading through that document much information about the history of Generac and the current status of their business was found. Also their pressure washer comparison tool was used to find the difference between each.
