Best Generac Pressure Washer Reviews – Buying Guide & My Picks

Generac first came into the public eye in the 1950s, when it started as a company making small portable generators. As they’ve grown over the years, Generac has expanded into other sectors, including pressure washers. They put a lot of time and research into making dependable and efficient machines of all types. Currently, Generac is known for making some of the best gas powered pressure washers on the market. Just like their generators, Generac makes every unit with quality and reliability. And that’s exactly why they’ve become so popular commercially and residentially.

These pressure washers below are a step up from smaller, electric units designed strictly for residential use. When those smaller models can’t get the job done, it’s time to call in the Generac big boys. While these units are technically ‘residential’ themselves, their gas power makes them very useful.

Let’s take a look at our reviews of these best Generac pressure washers below and how they measure up with one another.

1. Generac 7019 OneWash 3,100 PSI, 2.4 GPM, Gas Pressure Washer

If you’ve been browsing the internet and researching your pressure washer options, you may have stumbled upon the Generac 7019 already. After all, it is a great model and is well known in the industry. It is built on two foundations: power, and reliability. The motor is strong and reliable. Not only do you get a max strength of 3100 PSI, but you get a motor that will not quit during a long day at work. Some users have Generac pressure washers still going strong after 10 years of hard use!

Although the Generac 7019 would be considered heavy duty to some, it is designed to be easy to use. Assembly is user-friendly. The hose connects are conveniently placed to avoid having to kneel on the ground. It is even relatively easy to move thanks to its design. Tall, ‘never flat’ wheels offer the support a unit this size needs. The weight of the unit rests over the axle. For Generac, strong and powerful does not equal cumbersome.

Keeping with the convenience theme, let’s move on to the detergent tank. The easy to load tank holds a half gallon of material. This capacity can save time by cutting down on refill times. It’s also easy to clean, when the time comes.

Generac’s ‘Powerdial’ applicator helps manage the potential 3,100 PSI the 7019 is capable of producing. The settings let you change water pressure on the fly. While it’s true that some jobs require a full 3,100 PSI to be effective, having the option to use less pressure adds to this unit’s versatility.


  • Sufficient power for tough cleaning jobs
  • Reliable 196cc OHV motor
  • Convenient, user-friendly design
  • Large capacity detergent tank
  • Powerdial handle allows quick changing of pressure levels
  • Gas powered


  • Not heated
  • Instructions are poorly written

2. Generac 6922 2,800 PSI, 2.4 GPM, Gas Pressure Washer

Generac’s 6922 model could be considered the little brother to the very similar 7019 model. It has a little bit less power, maxing out at 2,800 PSI. The unit is no slouch, however, and it would be classified as ‘medium duty,’ rather than heavy. It also has a respectable 2.4 GPM flow rate, the same as it’s older brother. For this reason, the Generac 6922 has become one of the leading choices for gas powered residential pressure washers.

There are more similarities that you see when looking at the overall package. These two units look pretty similar, and that’s because they both have been designed for ease of use. This model also uses ‘never flat’ tough wheels that make maneuvering the unit easier. These wheels definitely come in handy when working in less than ideal terrain.

And just like the 7019, the 6922 is set-up so hoses can be easily connected. The pump is at the same height as the engine, which makes connecting the hoses easier. Some units have connectors that are much harder to reach and are not user-friendly to stay the least. The detergent tank has a similar capacity – about a ½ gallon. Again, the tank was conveniently placed for user friendliness.

When using the Generac 6922, you’ll have a few different nozzles at your disposal. Their output ranges from 0 degrees to 40 degrees, plus a nozzle designed for applying soap. The quickly changed nozzles let you use the right amount of pressure for the right job. Tip: never go below the 40-degree nozzle when washing a car.


  • ‘Little brother’ to the Generac 7019
  • Medium duty classification
  • Suitable specification – 2800 PSI, 2.4 GPM
  • User-friendly design
  • Ergonomic handle
  • Easy to maneuver


  • Not a heated unit
  • Consumes gas quickly

Pressure Washers 101

Essentially, most pressure washers work the same way. First, water enters the machine at a low rate of pressure. The motor, which is gas for these models, powers the pump. The pump drives the water through the machine, hose, and through the spray wand at a high rate of pressure.

The water leaving the pressure washer is perfect for blasting off tough stains, grime, and grease. When combined with detergent and cleaning chemicals, you have a very powerful cleaning tool.

Choosing the Right Generac Pressure Washer

The two Generac models detailed above are excellent starting points if you are looking to add a gas powered pressure washer to your arsenal. They offer advantages that you won’t see in smaller electric units, which have been popular for residential uses.

The problem is that electric units are usually much weaker in comparison to gas units. Gas units, like the Generac 7019 and 6922, provide enough power to clean the toughest stains. Old stains, like oil on your driveway or sidewalk, can be stubborn and require the added power that gas brings. Both of these units offer similar levels of power output. If you are on the fence, consider your needs. If you need the extra power, the 7019 is suitable. If not, the 6922 is more than capable.

What Makes Generac an Excellent Choice?

Generac has grown to be a favorite brand among consumers, and that is not by accident. There are a few things that separate Generac from its competitors.

To start, their pressure washers are built to be more upright. An upright design offers a few benefits. The pump is located higher up on the unit, which makes attaching hoses a simpler and easier job. The engine and pump are both positioned over the axle. This configuration increases balance and maneuverability. Also, their in-house designed motors are reliable and are powerful enough to reach the 3,000+ PSI needed for tough cleaning jobs. These features are intended to make Generac pressure washers both user-friendly and powerful enough to handle tough cleaning jobs.

Another factor is the overall build quality of Generac products. They use high-quality materials throughout the unit. From the metal frame to the motor and pump, to the hose and nozzle. It’s common, in lower ranked models, to see companies cheap out on certain smaller parts. Often times these smaller, cheap parts can cause quite the headache when they malfunction. These Generac pressure washers ‘feel’ high quality when using them. They feel like products that can hold for the long haul. It’s fair to say that pressure washers and other outdoor appliances take on plenty of wear and tear. When making a bigger purchase like this, it is nice to know you have a product built to last.


The main specifications that you see listed for pressure washers include PSI and GPM.

PSI – Pounds per square inch, or the amount of pressure applied by the washer. Light-duty models usually have below 2,000. Medium duty rates between 2,000 and 2,800 PSI. Heavy duty units top out at around 3,300 PSI. For higher levels, you’ll need a commercial grade unit. The higher the PSI, the deeper the cleaning.

GPM – Gallons per minute, or the amount of water which can pass through the unit within a minute. In some cases, the GPM can be much more important than the PSI. The GPM rate is responsible for a better cleaning and for reaching harder to access areas.

Essentially, the higher the combination of these numbers, the more thorough and in-depth the cleaning. Many models, like the two Generac’s reviewed here, have adjustable modes or nozzles to control PSI levels for specific jobs.

Pressure Washer Tips and Tricks

Never point the spray nozzle at people, pets, or plants. Also, avoid electrical fixtures, power lines, etc. At close range, 2,000 PSI can easily rip thru skin – as well as gloves, boots, pant legs, etc.

Use the correct nozzle or setting for the job. Nozzles, which change the output from ranges of 0 to degrees to up to 40, can drastically alter the amount of water delivered and the pressure at which it is delivered. Too much pressure can strip paint and easily damage some surfaces.

Wear safety gear. For using these Generac units, it’s recommended to use eye and ear protection. Pressure washing can cause caked on grime and debris to go flying everywhere, including into your eyes. Plus, having a shield between your very sensitive eyes and the powerful jet of water leaving the washer is important. Gas units also produce enough noise to warrant basic ear protection.

Don’t leave the spray wand unattended. It sounds dramatic, but treat your spray wand as if it were a loaded gun. Don’t leave it unattended while the unit is on. If a child or pet were to accidently pull the trigger, someone or something could be injured.

Generac Pressure Washer Features

Here are a few of the features found on Generac pressure washers, and the functions they provide.

Onboard detergent tanks – The tanks, which are found in both Generac models listed above, adds to the user friendliness that Generac strives for. They make using cleaning chemicals easier to deal with. Their location also makes for easy cleaning when the time comes.

Changeable nozzle tips – These tips are what determine the rate of flow and the pressure applied by the wand. The narrow tips product a high powered stream with more pressure but less total coverage. The wider nozzles give less pressure but offer a wider cleaning area. Both models that are talked about here, the 7019 and 6922, also come with a soap nozzle. The soap nozzle is perfect for presoaking tough stains.

Never flat wheels – The wheels found on these pressure washers goes a long way in the user friendliness column, believe it or not. They are tall and made with a sturdy plastic material. They help balance the unit and help it travel easily across pavement, as well as wet or dry landscaping.

Elevated pump – The pump for these Generac’s is located higher up on the unit. It’s much easier to reach than a pump located near the ground. The pump location makes changing hoses quick and painless. Some also believe that the location of the pump helps save wear and tear.

Are these Generac Power Washers Overkill for My Needs?

If you’re an electric pressure washer owner, you may be looking to upgrade to something more powerful.If so, you may be wondering if these units are simply overkill for your needs. Instead, think of the versatility that adding a more powerful unit can provide. First off, through different nozzles and extensions, you can manage PSI and pressure levels to fit any job. You’re not stuck using the maximum pressure levels. This means you can be gentle when the job or surface requires it. On the other hand, you have the extra power at your disposal if and when the job calls for it. In this regard, it makes much more sense to opt for one of these Generac models, because they can handle whatever you throw at them.

Bottom Line

These Generac pressure washers are some of the best available for residential uses. Being gas powered, they are more capable than the commonly found, smaller electric units. But they were also designed to be ergonomic and comfortable to use. The easy pump configuration, durable wheels, and upright design help the most. If you are in the market for a pressure washer for your home, you can’t go wrong with either the Generac 7019 or the Generac 6922.
