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.

Rated 5 out of 5 by from This machine can handle it all. I wanted a machine that could reach the top of the second floor of my house from standing outside the basement door. The 4200 met the challenge. This thing is a beast. I'm glad it came with a support handle on the wand. Delivery was excellent, on time, no damage. First time start took 5 pulls and runs like a dream. The interchangeable tips are great. I was able to clean the siding, driveway and my truck without issue. I believe in crying only once on a purchase of this type. Spend a little extra and be satisfied for a long time. I went with the best and got exactly what I paid for.

Rated 5 out of 5 by from 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.

Rated 3 out of 5 by from works great after I got it fixed The pressure washer works great now but the first 4 months I owned it were nothing to talk about. I could not use it. Tires were flat, parts fell off and it had an oil leak. After finally getting them all fixed with very slow tire replacement, it now works as its supposed to.

Rated 1 out of 5 by from Well...It looks good, but it is leaning to one side. I purchased the 4200 power washer and it was delivered with the bearings falling out of one of the wheels and it didn't have the pressure washer hose with it. I haven't been able to even try it yet as I am awaiting the hose and bearings for the wheel that I will have to repair myself. So far I am very unimpressed. I will write a review when I actually get to use it. I can't believe it passed the quality control procedures at Generac...Now I am worried! So far this is the only rating I can give it. Sorry!

Rated 5 out of 5 by from 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.
