Rated 4.0 out of 5.0 by Generac 3100psi good to excellent Read instructions and manual thoroughly filled with proper oil,and regular gas.Started right up washed my house and driveway with ease,machine worked excellent. Only slight problem was psi hose kept curling up it was wrapped in tight circle in box. I stopped machine unhooked psi hose stretched out on driveway in the hot Florida sun ate lunch,everything worked great. Next day washed my sisters house and driveway with no problem and with excellent results. This is a great machine and great price at the Depot. I would definately recommend to a friend or any body.

Rated 5.0 out of 5.0 by This product is easy to operate and works well. I found this product was easy to operate, and was completely satisfied with the finished job. My sidewalk looks amazing and couldn't believe just how dirty it was. I didn't even have to use a cleaning solution May 15, 2013
Rated 5.0 out of 5.0 by Best Pressure washer for the money Within 5 minutes I was able to start washing. Cranked on the first pull and has cranked on the first pull at least 10 times since then. I have put about 7 hours on it and everything is working great. The washer is plenty powerful for all household projects. I had purchased a Homelite equivalent to the Generac and returned the Homelite. The Generac is built much better although the quality of the hose could be better no other comparable washer has a better hose. Gas tank is large enough to last over an hour of continuous running. The oil can be checked from both sides of the engine and the hose hookups are conveniently located in the rear for easy connectivity. August 14, 2012
Rated 4.0 out of 5.0 by Great value ,excellent performance First power washer for home use ,very easy to use. August 22, 2013
Rated 5.0 out of 5.0 by Excellent Pressure Washer This truly is a good pressure washer. I had bought another brand from home depot but it was so difficult to start and had a leak from the pump immediately. So I returned it and did a lot of research. I have no clue why home depot doesn't stock this, it's by far better than anything else. It's easy to start, comes with quality components and is competitively priced. I would recommend this to anyone. It cleans my stained concrete driveway effortlessly, my brick home, my cars and even stripped the paint off an old outside table and chairs August 7, 2012
Rated 1.0 out of 5.0 by HORRIBLE!!!!! Washer arrive with a broken air filter cover. Called Generac Customer on a Saturday and was told I would receive a new cover by the following Friday. Tomorrow has been 5 weeks since I first called. No cover yet. I have called many times, and get the runaroiund every time. I finally spoke with a Supervisor, and she assured me that she would contact me the next day with some answers. That was 3 days ago, and she has not called me back, and will not return my messages. Don't know how the washer works, the the customer service is the WORST I have ever dealt with in my life. Save yourself the aggravation and get a different brand. July 18, 2013
Rated 5.0 out of 5.0 by No Regrets, Quality Machine Well ... One regret: plastic on the gun was broken on delivery. Quick phone chat ... Replacement on the way. Easily set up and running great. Have used other washers, incl rented ones, and this one has as much or more power than any of them. Beware of blasting out wood with that most forceful tip. Fires rt up every time. Note: accidentally filled it with gas/oil mix and seems to be no problem so far; runs fine and my research concluded not to worry about it as long as it starts and runs ok. I love my power washer! If I change my mind for some future reason I will try to update this review. June 7, 2013
