4. The Generac Onewash has 3100 PSI and 2.8 GPM. Combined with an OHV engine of 212cc, this makes it the most
powerful pressure washer in its class and in our selection of 5 best power washers.
Its best feature is the PowerDial™ control that let you change the water pressure just by turning a dial. What it
means is that you can clean anything safely and easily.
You can, of course, clean your patio and patio furniture but not only. The Onewash can be used for your car, your
driveway, your fences and decks, and even the toughest of concrete.
It’s like having 4 washers in 1 and you will appreciate its versatility greatly if you are a DIY kind of person.

wheels and you can easily move it around even if your terrain is very rough. It’s also precisely balanced to improve
stability and effortless mobility.
Its 30-ft hose will also give you an extended range of action.
The controls are all located in a single control panel for ease of use. And it has a comfort-grip handle.
The axial cam pump is designed horizontally which makes connecting the hose easier.

The OneWash is very safe for a gas pressure washer. You should of course follow the usual safety rules when you
are using it.

6. Buy from Amazon
Let's take a look at the Onewash:
Is there anything else I need to know?
The Onewash comes with 3 nozzle tips, black, green and red. Since you can adjust the pressure with the
PowerDial™, they are all you need. They are conveniently stored in front of the washer so you can reach for them
effortlessly when you need them. Plus, they use Quick-Click™ nozzle tips which you just have to click into place.
The Generac 3100 PSI pressure washer comes with a folding handle for a compact storage.
Customers have indicated that it doesn’t use a lot of fuel . The main complaint of customers has been some missing

7. parts in the package. Make sure you have everything when it arrives. It would be better to use Amazon and not the
other sellers in case you have a problem.
The second best feature from the Onewash power washer is its ergonomic inverted trigger. It means that you can
use it for extended period of times without feeling the hand fatigue usually associated with pressure washers.
Should I buy the Generac 4 in 1 Pressure Washer?
The Onewash is very impressive and innovative. The PowerDial™ makes it very versatile and easy to use.
The inverted trigger makes it very comfortable to use and you will appreciate this feature if you are planning to use it
a lot.
The great features are very impressive on paper but there are numerous critical reviews on Amazon stating it's not
as sturdy and reliable than it should be.
It’s the same price range than the Simpson Megashot but usually gets slightly lower ratings. For the same price, we
would favor the Megashot.
The Generac would be more suited to someone having occasional and light cleaning jobs to do.
What is included in the price?
The price and the shipping box include:
30-ft Hose
Ergonomic Spray Gun
3 Quick-Change Nozzle Tips
2-year limited warranty

year. It’s likely to be cheaper in wintertime.
It comes with a 2-year limited warranty.
FAQs
Below are the most frequently asked questions about the One Wash:
How do I use the detergent tank?
You fill the tank with detergent and the siphon hose is kept in place thanks to the holed-screw cap. It's very
convenient.
Why does it come with only 3 spray nozzles?
Since you can adjust the pressure with the PowerDial, 3 nozzles is all you need for most of your cleaning needs.
Can I use it for a 2nd story house?
Yes but you'll have to buy a 2nd-Story Nozzle.
Can I use it with a water tank?
No. You need a running water supply that supplies 3 plus gallons of water per minute to the pump.
8/11

9. What gas do I have to use?
Generac recommends utilizing clean, fresh, unleaded gasoline. Moreover, the fuel should be a minimum of 87
octane/ 87 AKI (91 RON) gasoline, with up to 10% ethanol (gasohol); do not use unapproved gasoline such as E85.
Note that modifying the unit in order to use it with different types of fuels would void your warranty.
Can I use hot water?
No. Never use water more than 100°F or 37°C.
Can I use bleach?
No. Always use a pressure washer safe non caustic detergent.
Does it have an electric start?

10. Verdict
The Generac 6602 One Wash is very interesting and certainly worth considering. I’m seduced by the PowerDial™ as
I don’t particularly like the idea of changing the nozzle tips all the time. The inverted trigger is great if you’re going to
use it for several hours but it’s not exactly my case.
In our Generac Onewash power washer review, we have seen its many benefits and innovative features. We have
seen that it’s a very versatile washer which is perfect for all your residential needs. It comes from a leading
manufacturer and is of high quality. Now you know everything you need to know to make up your mind.
