Rated 4.5 out of 5 by 138 reviewers.
Rated 4.0 out of 5.0 by Great product, very minor equipment drawback Excellent product. Very easy to put together and use. All of the accessories it comes with are good as well except for one minor issue. The holder where you store the hose when you are done doesn't hold the hose very well. The hose unravels cause it needs to be a bigger, sturdier holder. Everything else is great. Big tires for ease of movement, the holders for the different tips....would recommend to a friend.

Rated 5.0 out of 5.0 by Great value So far, this has been a great product. Since getting this product 2 weeks ago, I have pressure washed the driveway, patio, boat, and started on the wood fence. My wife loves it too. The only problem is that she keeps finding me more projects to do. A great product for the price. March 18, 2013
Rated 5.0 out of 5.0 by Super Duper I've had this for about three weeks and it's been great. The driveway is white again and the decks are cleaner than they've been since they were new. I added a brass quick connection at the garden hose port and have a brass shutoff valve on the end of the garden hose right behind the quick connect. Quickly disconnecting the hose makes it much easier to move the pressure washer and set up again. I did purchase a 15 degree nozzle, from a local source, because it gives a little more umph on the really tough spots. The unit only comes with 25 degrees and a straight stream plus a soap nozzle. The 15 degree nozzle is a worthwhile addition. This is a nice piece of equipment. I'm finished with electric pressure washers. September 11, 2012
Rated 5.0 out of 5.0 by Great Product I purchased my Generac Power Washer based on the positive reviews I read, and have not been disappointed. Assembly was a cinch; nothing more than reading the instructions and attaching a few parts. It started the first time I pulled the cord, and has continued to start on the first or second pull ever since. Pleanty of power for most jobs. My only complaint was when I tried to change the oil as recommended after the first few hours of operation. The drain plug is hard to reach and calls for a metric socket, which I didn't have I couldn't budge it with vice grips. I ended up draining the oil out of where you put it in, which was a mess. Other than that, a fine product. November 12, 2013
Rated 5.0 out of 5.0 by It's Great ! Added the oil ..and it cranked up first pull... I have used it to wash my concrete patio, 5th wheel ,pool deck etc. every time it has cranked up with the first pull.. I like the on-board tips so I won't loose them . This is my first gas model and the reviews were good so I gave it a try ...Love it ! December 5, 2012
Rated 5.0 out of 5.0 by Product Works well I was concerned that it wouldn't be powerful enough, but bought it because of the good reviews. I have had it for a week and so far I am very pleased. It arrived by UPS. The packaging was damaged and taped up. The packaging (box) is more suitable to be stacked and shipped to a store on a pallet rather than individual shipment to a residence. However, the product did not appear damaged. The manual implied that oil was included but if it was, it may have fallen out when the box opened in shipment. The washer assembly was very easy and only took a few minutes. Once set up it started in 2 pulls. I used it to clean off a wooden fence. It had more than sufficient power and I was pleased with its performance. The second day it started on the 2nd pull but after about 30 seconds the power of the stream was sputtering, I was concerned but after about 25 seconds it resumed full power and I had no problems after that. So far I am happy with its performance and would recommend it to a friend. November 19, 2012
Rated 5.0 out of 5.0 by As well made as predicted It's the finest quality at the most affordable price. Anything else as good was twice as much money. February 14, 2013
Rated 5.0 out of 5.0 by Does what a 2500 psi 2.3 g/m PW should It works great. Please read the directions. Inexperienced users can learn a lot from them. I know I did. This is my first gas powered Pressure Washer. The guy who says he loses pressure on and off as he goes doesn't understand why. The pressure washer is drawing 2.3 gallons of water per minute from his garden hose. If the PSI drops below 30 as a result, the hose will contract because of the vacuum created in it. That squeezes off the water from flowing. until it can "recharge". Any sufficiently powered pressure washer will behave the same way on your system. Get yourself a solid garden hose that wont contract under vacuum. Or add a pressure booster to your water supply. May 26, 2013
