Rated 5 out of 5 by from This product will wash the other ones away I was astonished at the power of this pressure washer. It cleans like there is no tomorrow. We’ve owned it for only a month, I’ve cleaned 3 decks, siding on our house, the truck and camper. My wife’s parents own the generator (5 years) and have hade NO PROBLEMS. It’s easy to use and easy to transport. Assembly was to easy. Customer service was fantastic , getting it registered over the phone was a breeze. Thank you Holly!

Rated 5 out of 5 by from Great washer for the price This is my second Generac pressure washer that I've owned. The first one lasted about 25 years and when it died, I knew what brand I was going to purchase. The model 6921 is a great washer for the price. Very ergonomic and easy to use. Plenty af water pressure for the average residential home. I do a lot of off-road riding and the 6921 is up for the challenge when it's time to clean everything up. Mud, coal dust or what ever I throw at it, is no challenge for this washer. I'm very pleased with my purchase. Hope it last just as long as my last one
