Rated 4.0 out of 5.0 by 35097 Great performance but...watch out for that axle snap ring!!!!
MINOR CON: Adding oil to the motor is a bit tricky given its placement.
MAJOR CON: Vibration from motor caused snap ring to come off axle, Axle vibrated out and unit collapsed. This was on first use on day 1. Ring was unable to be found (probably "blown away"). I was very annoyed that I had to stop, clean up and go buy one on my new $900 unit. LIVID. With my new 25 cent snap ring now installed on day 2 being cautious I was looking for it and the snap ring again came off the axle. NOTE: axles and wheels come assembled on unit. Problem seems to be a design flaw given the obvious vibration when unit is used. .
PROS: As advertised it is a VERY powerful pressure washer and it cut the time down on my job significantly. Starts easy but you need to be able to give it good rip on the pull (older users may be challenged). Performanc was excellent.

Rated 5.0 out of 5.0 by MattieB Excellent do it all pressure washer
I opted to go with the 4200 PSI since I've got a 2-story house. The tip selection allows me to get the majority of the second floor without using a ladder.
Variable pressure speeds allow me to adjust based on what I'm cleaning. I use this to clean my cars, UTV/Quads, driveway & house. It's amazing what a good pressure washer can do to restore dirty concrete walkways.
This replaces an older 3000 PSI electric one. For my side by side this has cut my wash times from over and hour to being done in about 15 minutes!
My only compliant is it can sometimes take a few pulls to get fired up. You have to let it run half choke with the wand open for about 2 minutes before you can take the choke off without killing the motor. It would be nice if you had an electric start version, not super hard to start but it's more convenient.

Rated 5.0 out of 5.0 by jonnyvusmc Amazingly powerful and awesome power washer!
I bought this unit to replace a smaller Karcher pump with Honda engine that quit work (broken shaft). I have used a $6,000 trailer mounted Shark belt driven steam/power washer that is not as nice and powerful as this Generac unit it. The Triplex pump is awesome, excellent pressure and very good GPM. It isn't all about pressure when washing heavy equipment, you have to have a large volume of water and this pump does it.
I'd recommend to anyone who isn't just washing a deck and needs some power. The only issue so far is that the paint is burning off the exhaust but not really an issue. Also it is Made in USA.

"The right tool for the job" has been my motto in jobs around the home and my business and this beast is the right tool for pressure washing anything at the commercial or domestic level. We wash the swimming pool deck, the tennis court, the decks, the patios, exterior walls, fences, and a lot more! It's so much fun, friends and neighbors get some love, too.

I have been using the 4200 psi 4 gpm pressure washer on commercial jobs and it can handle any job. I use surface cleaners and extension wands and have had excellent results. My first machine has 270 hours on it and my second already has 20 hours on it. The older machine runs just as good as the new machine and isn't showing any signs of stopping.

Rated 1.0 out of 5.0 by Karsten Had high expectations, but am very disappointed by Generac
The design and features of this product made me order this pressure washer. It shipped directly from Generac in WI. But when I received the pressure washer I found out, all of the accessories (Pressure wand, Suction hose, Nozzles,) were missing. Guess somebody at Generac screwed up big time. So, I directly called Generac customer service and informed them about the missing parts. They told me it would take 2-weeks to send me the missing accessories. Completely unacceptable! It actually took Generac almost a month to ship the missing accessories. I am glad I returned this Pressure washer to Homedepot and went with a Dewalt/Simpson instead.
Due to this experience I will never buy a Generac Product again!
