The Best Generac Pressure Washer

Best Generac Washers Thumb

Updated: 8 min read


Let&#;s take an in-depth look at: Generac Power Systems Inc., the 3 best gas-powered Generac pressure washers and two pressure washer features customers want Generac to improve

Generac Power Systems, Inc. by the numbers:

  • Since Generac became a public company in , its share price has increased %, beating the market by % over the same time frame.
  • Its market cap today (Feb, ), 7 years after IPO, is $ billion.
  • Year ending saw yearly net profit of $78 million off $ billion in sales.

Not bad for a generator company started in to make home-use portable generators for Sears under the Craftsman name.

Their current President and CEO, Aaron Jagdfeld, has been with the company since , when he started as an accountant. He became CEO in , after serving as CFO for 5 years. He currently owns % of Generac shares making him the single largest non-institutional holder.

Judging by the share price, his strategy of expansion and generator fortification has been spot-on. During his tenure Generac has expanded with key acquisitions into these markets: generator powered lighting towers, industrial diesel gensets and mobile heaters.

Generac&#;s core focus is power generation products. To support their business focus, they have an extensive in-house engineering, design and manufacturing capability.This allows them total control over the specs and features of each model of pressure washer gas engine and pump, for example.

Their manufacturing facilities are in 8 different locations: 5 in Wisconsin, 1 in Italy, 1 in Mexico and 1 in Brazil. 3 million square-foot of space in total, which is equal to  football fields of floor space at each location.

Generac Surprising Fact Box

Briggs & Stratton portable generators and power washers are engineered by Generac.

Follow this timeline to see how this can be:

  • &#; Generac sells off their portable products division to Beacon Group, which included portable generators, power washers and water pumps
  • &#; Beacon sells it to Briggs & Stratton who then starts selling those generators and power washers with Briggs branding
  • &#; Generac&#;s year non-compete agreement expires and they re-enter the portable generator market
  • &#; 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 washers are best for most peoples needs.

Quick Review of Best Generac Options

Here is a quick summary review of the 3 Generac pressure washers that are recommended on this page:

Generac Pressure Washers In The Wild

Generac is an electric generators company. It is far-and-away their biggest revenue driver: 72% of their $ billion revenue came from commercial and residential generator products. You see their generators everywhere.

But what about their power washers?

Well, it turns out, they are quite popular too. As Generac makes a push into the power products market with the acquisition of Country Home Products ( and Neuton Mowers brands) you will begin to see more and more Generac power equipment in the wild.

Here are 5 pictures of pressure washers unboxed hooked up and ready to clean:

Picking The Best Generac Gas Power Washers For Most People&#;s Needs

Adjustable Pressure at the Turn of a Dial &#; Best Value For The Money

1) Generac SpeedWash 3, PSI

Generac SpeedWash Pressure Washer

Do 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.

One machine for all these cleaning tasks:

Generac Pressure Washer Recommended Uses

The OneWash has 4 settings between 2, and 3, 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 $ more (than the cheaper #2 choice below) for the variability (and extra cleaning power) then get it while it has free shipping.

Hits the Sweet Spot With More Affordable Price and Hefty Cleaning Power

2) Generac 2, PSI

Generac psi medium duty pressure washer

The best Generac for many people could be this one because it is the most affordable medium-duty with 2, PSI (1, psi to 2, psi is medium-tier so just fits in range).

It&#;s about &#; 2x the price of other electric medium-duty pressure washers&#; But you get the extra power and flow to easily complete big driveways in one-hour instead of three.

Using the 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 2nd best (not 3rd of 4th) Generac for most?

It hits the sweet spot in price and power &#; 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 is cheaper but only 22% less cleaning power than the OneWash #1 best above. The reason the OneWash is much more expensive is the jump from medium to heavy-duty pressure as well as the addition of the adjustable pressure and required components. Basically, the OneWash needs a bigger engine to support the higher PSI and GPM pump.

This Generac is top-class and if you want to make quick work of your driveway, deck, garage floor, fence, back patio&#; It is one of the most affordable gas powered pressure washers. And given the durability of a gas engine, you can guarantee this machine will last you 10 years or more with proper care.

What About Their New One Touch Electric Start Model?

3) Generac w/ Push Button Electric Start

Generac New Electric Start Gas Pressure Washer

Generac Power Systems, Inc. is currently heavily promoting their new model gas power washer with a Lithium-Ion battery &#; push of a button &#; electric start. The battery will provide 50 push starts before needing charging.

It has 3, PSI and GPM and costs about the same as the more powerful SpeedWash model.

Is the convenience of push button start worth it?

If you have a bad back or trouble using the recoil pull start then you&#;ll love the simple starter button technology.

Consider These Two Upgrades

Constructive reviews suggest purchasing a better hose and a surface cleaner for quicker cleaning of large flat areas.

Upgrade Hose

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.

Surface Cleaner

Generac surface cleaner attachment

You connect the lance to the surface cleaner and it distributes the spray evenly over a larger area making quicker work of the driveway and other large flat surfaces. It is one of the best ways to increase the cleaning capacity and efficiency of your Generac power washer.

See full specs here&#;

3 More Generac Pressure Washer Parts and Attachments To Upgrade Cleaning Performance

1.) Extension wand and gutter cleaner attachment

A telescoping extension wand allows you to clean second storey windows and house siding while keeping safe on the ground. No more ladders required. Get a gutter cleaner attachment which is a curved lance letting you clean your gutters out while staying safe on the ground.

2.) Rotating scrub brush

A scrub brush lets you clean tough spots without risking surface damage. Your car wheel wells and grill are two areas that come to mind. Also, your garbage can might have tough stains a scrub brush could make quick work of. Try one out they are very affordable.

3.) Floor and stair sweeper

Generac pressure washer floor sweeper attachment

A floor and stair sweeper is a rectangular attachment with 4 nozzles distributing the water flow to increase cleaning area and save you time. It is perfect for cleaning stairs 4-times faster than with the regular nozzle and does a less streaky more even clean. The round surface cleaner is not efficient at cleaning stairs so the floor sweeper might be a better option since it can also do driveways and decks.

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. You have 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. They&#;re affordable, useful and fun to use.

 Frequently Asked Questions, Answered

1.) How does the Generac OneWash model with adjustable pressure work? How does it have variable pressure? Does it have a special valve?

It uses a Bowden cable connected from the turning dial to the motor throttle to control the motor speed. Turn the dial clockwise from 2, PSI to 3, PSI and you increase the motor speed, ultimately increasing the velocity of water out the nozzle. More water velocity out the nozzle means more water force on the surface area. Force over area is pressure (PSI). Generac engineers have calibrated to ensure amount of dial turn equals correct throttle movement for PSI it tells you on dial.

Here is a Bowden cable used to throttle a lawn mower from the handle so you can go from short thin grass cutting to long thick grass without bending over. You just shift from turtle to rabbit speed and the shifter is connected to the throttle by a Bowden cable to do all the work.

Bowden cable throttle connection honda mower

A Bowden cable is also used on your bike brakes to connect the brake lever on the handlebar to the brake calliper at the wheel hub. The Bowden cable is used to transmit the pulling force via a steel cable moving inside a hollow rubber/plastic outer protective sleeve.

2.) Where can I find the Generac pressure washer manuals?

Generac&#;s website has a page to find your specific model User Manual. But personally I prefer to use because if you don&#;t have the model number handy you will keep getting error messages. Here is the link to all the Generac pressure cleaner manuals.

3.) Does Generac make commercial-duty pressure washers?

Commercial duty generac power washer

Yes. Generac redesigned their professional offerings in and now have a belt-drive machine with Annovi Reverberi triplex plunger pump.

It has a suggested retail price of $1, and comes with specs of 3, PSI and GPM.

It looks pretty snazzy too.

Check it out here&#;


A great reason to buy a Generac is because they design and manufacture their own engines and pumps. This means they control the quality A-Z. No faulty final product makes it into the distribution warehouse. It&#;s caught by quality control.

Also, with their tight-knit, happy and dedicated team (Generac is one of the top places to work in Wisconsin), they can listen and respond to feedback from customers very quickly. That is how they have improved their pressure washers year-after-year.

Generac 31oo PSI Electric Start Pressure Washer is an Excellent All Around Model for Consumers

When the job requires more than an electric pressure washer gives you and your budget is less than Pro, the Generac PSI Electric Start Pressure Washer is worth taking a serious look at. It has more gunk-blasting power and volume than electric with some features that make it easier to use.


  • More pressure and water volume than electric models
  • Lithium-ion electric start system with recoil backup
  • Auto choke
  • Adjustable power dial on the wand


  • Wand holster connection to the frame is weak
  • Rear-facing hose connections make moving with hoses connected more difficult


While there&#;s definitely a difference between the build quality of the Generac&#;s consumer and Pro lines, the Generac is a powerful, easy-to-use pressure washer for consumers looking for more power than an electric model can offer.

The biggest advantage it has over its competition is its electric start. If you&#;re tired of pulling a cord, the Generac PSI Electric Start Pressure Washer is one of the few offering an electric start without moving up to Pro prices. When you&#;re looking at a gas model for occasional use, that&#;s a big deal. 

Upgrade Your Cleaning with the Generac PSI Electric Start Pressure Washer

Pressure Matters&#; But So Does Volume

Many people look at the PSI to decide between pressure washers, but that&#;s only part of the story. Higher water volume moves more material than lower at the same PSI.

Generac Pressure Washer

The Generac PSI Electric Start Pressure Washer uses an overhead valve gas engine to boost your pressure to PSI with gallons per minute of water volume. Electric models get up into the mids for pressure and usually less than 2 GPM, though models like the Greenworks Pro brushless model are finally getting more volume.

Generac Pressure Washer

The combination lets you remove general gunk easier than an electric model so you get the job done faster.

Doesn&#;t PSI Get Into the Pro Range?

We generally consider Pro-level pressure washers to start around PSI and move up from there. However, it&#;s not just PSI that determines it. As we mentioned, GPM plays a part and we really like to see it push closer to GPM or higher.

The pump comes into play as well. This Generac pressure washer uses an axial pump. It doesn&#;t require much maintenance at all and does its best work on small jobs and less frequent use.

Generac Pressure Washer

Pro models move up to triplex pumps that require more frequent maintenance but can handle daily use and last longer.

There are also other differences like more robust frame builds and commercial engines.

Field Notes

Electric Start

The electric start system is fantastic on this model. It uses a power tool-style 12V battery that pops into place on the back and has a cover to protect it from water and debris. It has a longer life and is easier to work with than a lead-acid battery.

Generac Pressure Washer

The automatic choke system helps save some time and frustration. Of course, the electric start itself saves a lot of cord pulling frustration, too. The engine doesn&#;t always crank in the first second and you can engage the electric start longer than a recoil cord.

Generac Pressure Washer

Just don&#;t hold it down for 30 seconds &#; the engine should start in a few seconds or less. If it doesn&#;t, give it a break and try again. With an occasional use gas engine, it&#;s normal to take a few tries to crank up after sitting for a while.

Powerdial Gun

Generac Pressure Washer

What I like about the Powerdial lance is the easy picture dial setting. Just select the one that looks closest to what you&#;re working on, install the nozzle to match, and get to work.

Hose Connections

Generac Pressure Washer

The hose connections are as solid and easy to use as any pressure washer. The annoyance is that they&#;re on the rear of the pressure washer. The potential issues are that it&#;s tougher to move from one spot to the next when you have the hoses on and it&#;s possible to get grass clippings or other debris inside if you pull it behind you.

Holster Connection

The holster itself plastic and about as solid as any other consumer pressure washer. It uses plastic push fasteners (Christmas tree fasteners) and their ability to hold long term is questionable. We&#;ll end up drilling a hold all the way through the frame and replace them with stainless steel fasteners.


Additional Features

  • Vertical axial cam pump
  • Never flat wheels
  • Onboard detergent tank


The Generac PSI Pressure Washer has an MSRP set at $ and that&#;s what most major retailers are selling it for. Here&#;s what comes with it:


  • 0º, 25º, 40º, and soap nozzles
  • 25&#; PVC hose
  • 12V lithium-ion battery and charger

There&#;s definitely competition in this space and you can go slightly up or down in PSI and GPM along with the price. Here are some options that have the same specs:

  • WEN PW $ (OEM engine, no electric start)
  • Craftsman CMXGWAS $ ( PSI, OEM engine, no electric start)
  • Ryobi RY $ (OEM engine, no electric start)
  • Ryobi RYB: $ (Honda engine, no electric start)
  • Generac $ (Generac engine, electric start)
  • Karcher G XH: $ (Honda engine, GPM, no electric start)

Even though Generac is on the higher end of the price list, what really stands out is that none of these other models have electric start. Most aren&#;t CARB-compliant, either, but Generac is.

The Bottom Line

While there&#;s definitely a difference between the build quality of the Generac&#;s consumer and Pro lines, the Generac is a powerful, easy-to-use pressure washer for consumers looking for more power than an electric model can offer.

The biggest advantage it has over its competition is its electric start. If you&#;re tired of pulling a cord, the Generac PSI Electric Start Pressure Washer is one of the few offering an electric start without moving up to Pro prices. When you&#;re looking at a gas model for occasional use, that&#;s a big deal.
