When it runs, awesome...for ten minutes
This pressure washer when it runs is awesome! The only problem is, right off the bat, it runs about 10 minutes and shuts off. No problem starting again. Runs another 10 minutes and shuts off. So after first trial use it s already in for repair. Not what I expected for this price. I did a lot of research before I went with this one. I like the fact product is made in the USA. This pressure washer is really heavy duty and really makes the job easy....when it runs. I needed the pressure washer for a really big job I was contracted to do which will now have be delayed or I'll have to rent one or I will lose the job to someone else. I am hoping this is minor issue and I can give a better review at a later time

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.

Extreme Power
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.

A Serious Pressure Washer
"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.

It's a great tool
Whenever you do a project - it's always easier with the correct tool - That being said, This pressure washer is above and beyond the the others. The pressure washer allows the user to determine the level of force (water) that's needed for the job.

My initial start up required a few pulls - however it was brand spanking new - what do you expect. The more I use it the easier it is to start -

I use this for a business, and the more I use it - the more I continue to find features that I love.

Best Power Washer for the Serious
I bought this 4200 psi power washer to do some serious cleaning around the house. It has been flawless in getting the job done. Follow-up maintenance has been a breeze. You get what you pay for...and in my case I got my moneys worth. I look forward to many years using the power washer.

This is one powerful machine!
Delivered fast. Packaging excellent. I had only used household or residential size pressure washers prior to purchasing this Generac model online. The difference in the quality of those units and this Generac is well worth the additional $200-$300. This unit is the 4200psi 4 gpm. The only other thing I will say is, "You better hold on tight".

I am interested in purchasing the 6565 pressure washer. Please tell me the manufacturer/maker of the pump on this unit. Thank you. Anthony

BEST ANSWER: The pump type is a "Triplex Plunger" and its manufactured by Generac
Why does the title of this pressure washer says its a 4200 PSI but the specifications says max pressure is 3100
