Good product

Would Recommend

It is working as advertised. I have for over a year, and used it to clean a car, a boat, a motorcycle, a house, a driveway, a porch and for many other applications. I would say it is noisy and rattles more then some other brands but it does its job perfectly. it is very solid and good product. I would definitely recommend it to my friends.

Failed to start ... now to test the warranty on day 1

Would Not Recommend

I read the setup instructions and was happy with the packaging. The components appeared to be well protected with heavy cardboard. I continued the setup installing the few pieces and adding fuel and oil as described in the instructions. It appeared there had already been oil presumably from testing at the factory. I then hooked up with the water hose and cleared air from the line. Followed the instructions and while trying to pull cord to start there is not even the sound of it trying to st...

Easy to use

Would Recommend

Purchased from large box store. Was a good value and performed tasks well. Has performed well so far this fall. Will winterize it. Based on past reviews, will hope it works well next spring. An acessory that would be helpful would be a rest that you could put the nozzle in so the spraying distance stays the same on large areas like a driveway.

Thought it was great...until today

Would Not Recommend

Bought the 3200 psi speedwash model direct from Generac April 2018. It was great until today. Reliable, plenty of power. All around great. It's been used a few times to clean concrete around the house and to wash cars and clean gutters. Probably not much more than a dozen times since last April. Today, the rivets that attach the plate the engine is mounted on, attaching it to the frame came off. Yep, that's right. The engine dropped down and the oil dipstick was all that was keeping the ...

Great Product

Would Recommend

I used this pressure washer right out of the box for three weeks straight. It started right up every day, ran without a problem and did the job for me. I like the assortment of nozzles and the pressure selector on the handle is great. I am impressed with Generac.

Works Good.

[This review was collected as part of a promotion.] FIRST TIME SETUP The machine seems to work as expected. The wand holder installation instructions were missing but was easy enough to figure out. It seems a little flimsy but time will tell. The hose holder doesn't seem very sturdy either. l did have difficulty when setting up for first use as far as determining the proper amount of oil to add. There was a supplied container of oil and it is clearly stated in the manual the quality and type oi...

Would Recommend

I purchased this product online in June 2016. I use it multiple times each year cleaning our sidewalks, patios, decks and handrails, along with our dock and boat. Three plus years and still typically starts on the first or second pull. This power washer has been a work horse and a great value

Would Recommend

Purchased this unit for projects around the house. So far we have done our front and side porch, our sidewalks and a good portion of our lower level. The unit starts easily and works flawlessly. The only thing I would change is to install a longer hose.

Poor Quailty Assurance

Would Not Recommend

I purchased the One Wash pressure washer on a Saturday from a large home improvement store. On Sunday I assembled it, which is very simple. It would not start. On Monday after a little run around I was able to exchange it for another unit. Went home and assembled the new unit. Same issue. Had to take to an authorized repair shop. The carburetor was plugged with old fuel. Apparently the factory is testing the units with untreated gasoline and then shipping them out. I would not recommend a Genera...

Oveall a great Pressure Washer from Generac

Would Recommend

Purchased this product because I have a 22K Guardian Generac whole house generator that we love. Only recently purchased but have already used it for hours. I have previously owned other pressure washers which have usually been in the $300 price range, so this one comes close but I feel is worth a little extra money. Since I have owned pressure washers for the past 20 years I do feel I know pro's and con's. Pro's of this pressure washer far out weigh any con's. I LOVE where the intake and outflo...
