Rated 5 out of 5 by from A really nice Thank You! We purchased a generator and got the power washer as a Thank You. What a nice way to be thanked! We co-owned a Troy-Bilt power washer with family so weren't in the market for a new washer. But, with the free one, we decided to give the old washer to the co-owner. We just used the Generac washer today and it worked great! It is easy to move, easy to use, isn't too loud and it does a great job! So, thank YOU, Generac, for making a great product!

Rated 5 out of 5 by from Love It ! This Pressure washer is easy to crank every time. It cleans good. The only drawback is that the soap dispenser does not work well.

Rated 5 out of 5 by from Easiest Washer I ever used I have had two other washers in the past. I needed to buy a new one I shopped around for two months. I looked at engine type, wand type and power. Looks aren't important it's a tool. I bought the Generac 3100. I use it around the house, I live in Florida and need to power wash my lanai at least 4 times a year. It take at least 4 hours to do. I use the 3100 yesterday and I found it the to be the easiest to use and I don't know why but the wand and the nozzles are the best I have ever used. It's so maneuverable and the dial on the handle is very convenient when using it. I am amazed how good this is.

Rated 5 out of 5 by from This product makes spring cleaning easy I was very happy with the ease of operation and how well it cleaned the patio and pool area. I used straight water and it did a great job, didn't even need to add cleaning fluid, I would highly recommend this product.

Rated 5 out of 5 by from Cleans as if a professional company did the job I live in Florida where you must wash your house twice a year as black and green mold grows year round. I purchased a Generac Residential 3100 PSI power washer on 9/20/2017 and have used it for a total of ten hours. I am very impressed with the performance. The high pressure head cleaned my car port ceiling that is about 20 feet high with no effort. I did not have to use an extension brush which I had to use with my old power washer. I changed the oil after five hours and it was easy to do as Generac added a convent hole in the base plate allowing the oil to drip directly into a small container. I cleaned my driveway and a long walkway that had nine years of stains on it, now the cement looks like new. This machine has more power than I will ever need and the motor is very easy to start. With multiple spray heads, if I need less pressure, just snap out one head and snap in another. I am very pleased with my decision to purchase this machine Al Higgins, Tampa Florida

Rated 5 out of 5 by from Awesome!!! Irma made its way through our island and I knew Generac made good products, but this pressure washer exceeded my expectations for the heavy clean up work we needed to do in the aftermath. Not only is it easy to maneuver around, the quality is outstanding, and it's easy to start. My wife uses it as well and it's very manageable and a fantastic product!! Definitely highly recommend and would buy again!!!
