Rated 5 out of 5 by great features at a reasonable price! I purchased this product mainly for home use. I especially like the fact that this washer is built to last. This is a commercial grade washer with a triplex pump and with its ceramic pistons are durable, dependable and maintain great pressure. In addition, the pump can be serviced if needed. However, with normal maintenance, this unit will last a homeowner a very long time. It does everything it advertises and more and I highly recommend it. January 20, 2016
Rated 5 out of 5 by Great performance for the price Does a great job on everything I have tried. Simple to operate, easy to start and no problems. I like features like shut off from gas tank to carb to help avoid gunking it up if don't use for awhile. I use additive to gas to prevent this too but want to be careful. I had to get used to releasing pressure by triggering the spray gun if I shut off to move and then went to restart but not a big deal. Have a Generac generator used in a business which has probably been used 3-4 days a week for past 3 years with no problems so I expect this pressure washer will be trouble free too. December 6, 2015

Rated 5 out of 5 by quiet and runs nice pump apears to be durable hose and wand storage needs improvement mine is broken already. I think its a little bulky than it needs to be a little more compact for storage and movement through doorways would be benificial. it seems to have sufficient power and durability, runs smooth quietly November 14, 2015

Rated 5 out of 5 by overall Excellent piece of Machinery We use this pressure washer to wash off our walkways, industrial carpets,and all of the brick work around our property. This machine works wonders for our building. Everyone that comes to our building always complements us on our appearance. Thank you Generac for making such a great machine.

Rated 5 out of 5 by Best machine I have ever owned After dealing with several cheap models and replacing them often, I decided to do some research before purchasing a new one. This model was recommended by several websites and after reading the reviews, I decided to buy. I am not disappointed. This unit starts easy, runs along time per tank and has plenty of power. The quick connects make hook up and nozzle changes very easy. Sturdy cart and up top connections make using this a breeze. I have used this for 2 days straight without an issue. Hopefully it will continue to work for years to come. If your looking for a well built, reasonably priced PW with great features then this is it. August 18, 2015
