Rated 5 out of 5 by from Awesome Machine I first got the machine there was a piece missing out of the box. I called the customer service and they sent me the piece to the wand immediately. The box was damaged is when I knew something was wrong when I looked for all the parts. I purchased the machine for my cleaning business. It works great. I have been using it for almost a year. Fell in love with the machine I call it the "General". I love the 4 GPM I wish Generac would make a 6 GPM Machine as well. Awesome machine!

Rated 3 out of 5 by from 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

Rated 5 out of 5 by from 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 out of 5 by from 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.

Rated 5 out of 5 by from 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.
