    Great for home projectsFinally got to use this on back porch. Easy to start – some people think it’s loud but it’s not that bad. You need to get used to how to switch over to start the machine. I’d suggest watching the guide on what nossels to use for the job – that helped me a lot.Only thing I was not thrilled about was when I used the soap dispenser – I put the hose in the 1/2 gallon of washing solution and it goes thru it pretty quick, so caution on that. I don’t see a want to limit the amount of soap it dispenses.Other than that – It’s been doing a fine job on all the chores I had.

    Make sure you do not overfill the oil reservoirMake sure you do not overfill the oil reservoir for the engine if you do the engine will be hard to start or not start at all I did that when I first had it and I couldn’t get it going then I realize I overfilled the oil so I drain some oil out and try it again and it started right up my review has changed from a one-star to a five-star

    Sold me a unit with old parts. Leaked gasoline all over my floorBought it and when putting gasoline into it for the first time it leaked everywhere on my floor. Online the consensus seems to be old parts caused the immediate leakage. They sold me a unit with oil parts which led to it leaking everywhere.

    Not to bad for the price a little issueIt’s a great pressure washer,the only issue I’m having now is that even though I switch it to the water option it keeps spraying soap with the water,besides that it’s pretty good

  7. John B Griffin

    Very easy start goes a long way on a tank of gas.Very easy to assemble and starting one pull and away you go. Easy connection for hose. I wish the wond was longer but all in all I would highly recommend this for home use.

    Leaks oilUnit worked very well, started easily enough and the pressure was good. The only issue I have is that it leaks oil. I have yet to contact Generac due to medical issues.

    Currently not recommended to buyI purchased this machine in June 2021, half of the decal on the front of the cart has peeled off and ripped. The plastic piece that holds the sprayer in place broke within the first month. Finally today, the hose touched the exhaust side of the machine and it caused the hose to burst. This is why I’m now posting a not so good review. I been looking around, and there are better designs out there for the same money. If Generac warrantees any of the above deficiencies I will amend this posting.
