Almost 10 years old and starts first pull!

Would Recommend

I bought my pressure washer end of 2011 and was impressed then with it's easy of operation and the ability to dial in the PSI. What I didn't expect that 10 years later (while I was looking online for the manual) is that my One Wash would still run like the day I bought it. One pull and she always starts. I probably should change the oil (hence me looking for the manual). The only thing that I have changed was the O-ring set... but that was literally last week.

My second Generac washer

Would Recommend

I had a Generac 2700 psi 2.3 GPM washer for 7 years and it worked always well. Sold it to upgrade and since I had very good experience with this brand I chose a Generac 4200 psi / 4.2 GPM commercial model. This is a beast and very powerful. Features and performance are first rate I would not even look at other brands. Very happy. One issue soured the experience though ... I would recommend against buying direct from Generac and buy locally or from amazon. The freight and LT delivery process i...

Poor engineering design

Would Not Recommend

You make a good potential product. I have owned a 3200 PSI washer for three years and it has two faults. Number one, it vibrates like a SOB and secondly whoever designed it put the high pressure discharge connection right next to the muffler. I’m on my fourth 50’ hose because while using the washer the hose hit the muffler for less than a minute and burnt a hole in it. No they weren’t those cheap OEM hoses, they were high dollar hoses. On my last hose I even tie wrapped the hose to the handle on...

Customer Satisfied

Would Recommend

This is my first Generac Pressure Washer, and I have not used it yet, but it feels that it will do the job greater and clean than another brand. Generac you guys did a great engineering.Well production dedication and standing beside the products gave me the security in purchasing the pressure washer. Am very happy that I ran into this product and not the "other one" that in less than a week I had to return it.

Not happy

I have a one wash unit and my one wash feature is giving me fits and I can’t even find parts to fix it. The unit is extremely hard to start it just about breaks my arm every time I try to use it. I bought a generac because of the name and appearance but I am not liking it at all. It would be so nice to be able to actually use mine.

Great Pressure Washer

Would Recommend

[This review was collected as part of a promotion.] Powerful and easy to use. The only gripe I have which is small is the cheap bracket to hang the washer wand when not in use. Pretty flimsy. Overall though, nice product and hopefully with proper maintenance it will last for years to come.

Excellent Washer

Would Recommend

[This review was collected as part of a promotion.] A nice feature of this washer is the large gas tank, I pressured washed my house not having to fill the tank but only twice in 7 hours. Nothing worse than to fill gas in the middle of work, this washer is great around the house. I especially like the easy start up and drain hole to change oil as well. Change that oil after 5 hours, a must!! I like the soap dispenser, take the filter off the end of the plastic tube for the full effect of soap sp...

Been great except for one thing

Would Recommend

I've been using this power washer for about 5 years now and love it (for the most part). It starts right up and runs great. I only use ethanol-free gas in it (as I do for all my power equipment - highly recommended) and keep it in my basement during the winter (to keep residual water from freezing in the pump). My only complaint is it takes some effort to get the detergent flowing through the pump. I've tried using the built-in reservoir, but couldn't get it to work, so I just put the clear tube...

Oil in box and through out engine.

Would Recommend

Being a retired ag teacher, (taught small engine repair) it was good for Generac because I fixed problem when I got it free of charge. The problem was the unit was shipped with oil still in it after their test run. So after removing the spark plug, (getting all the oil out of cylinder), fueling with ethanol free gas, taking the oil soaked air filter off so it could breath, rigging a clean filter to the engine for test. (using industry leading filter paper), and after 44 pulls (making sure the co...
