This product is extremely versatile
Product is extremely versatile. Works great for cars to wood decks. The only problem is the soap dispenser. It does not seal and leaks badly.

Solid product for residential use
I purchased the OneWash based on the consistent reviews online listing product quality and it did not disappoint. It performs as advertised and even exceeded expectation. My only thought of a missing piece or part was not providing soap blaster and turbo nozzles that are included with lower cost models. Overall I am very happy with my purchase decision.

need servicing
I have model #0064360 accd to the book but online shows #6602. I am having a hard time getting a carburetor kit for it. It leaks around the bowl. The unit was starting OK but quit when closing the choke knob. I took the carb apart and put it back together properly. I may need a new carb. Where can I buy one and what is the part number? A diagram of the carb would be nice. When it works it is fantastic compared to other washers.

attention to enginering and quality are obvious
I researched for a pressure washer online and looked at several makes.The Generac One Wash really stood out with it's features and obvious attention to details . The engineering and quality of materials are top notch. Rated for residental use but pro quality is definitely in mind.

We've had other power washers and this is the best! We have used it so far on decks, sidewalks, patio furniture, and siding at our place on the lake. Easy to assemble. Much easier to start than other brands. Not too noisy. Great on gas. Very powerful. Great features like the folding handle for easy storage, different pressure choices for a variety of surfaces to clean, easy access to hose hook up, detergent tank instead of bottles, big wheels that make moving it around easier, and the long high pressure hose that we didn't have any problems with kinking and could reach the second level. We would definitely recommend a Generac!

Money well spent
This is the 4th pressure washer I have owned and is hands down the best. In my opinion it is the top of the line pressure washer for any home owner. I have a ten acre place, a mini farm if you will and it does the job. I just finished using the OneWash to power wash my standing seam metal roof on our two story farm house. It was terrific in removing the old tar/asphalt coating and blew away any other debris. Yet you can dial it back for areas where the 3100 psi is too much. I have never pulled the starter rope more than 4 times before it came to life. The only negative remark is the top part of the folding handle is plastic. I'm sure it will break eventually. When it does I will make a metal replacement.

This unit came packed well, assembled easy. It's very powerful for home use. I like the large diameter wheels. The handle folds down for compact storage.

The website was very hard to navigate. Machine is very quiet. An O-Ring broke after 5 hours of use.

Very difficult to start because of kickback even with depressurizing wand. Usually get someone to hold trigger while I start it

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.
