Rated 4.0 out of 5.0 by Good Pressure Washer for the money. Very Good Pressure Washer for the money. Easy to start. Easy to use. Completely satisfied with this product. April 28, 2015
Rated 5.0 out of 5.0 by We cleaned a very dirty driveway, no problem, too small gastank, otherways just first class. The unit worked perfect for the job we needed done. It worked very well. May 19, 2015
Rated 5.0 out of 5.0 by 3100-PSI 2.7-GPM OHV ENGINE AXIAL CAM PUMP GAS POWERED PRESSURE WASHER Got this model last year and used it all summer and fall, cleaned the vinyl siding on my house, the concrete side walks, pressure treated decks ever used it to clean my floor in my shop so I could paint it, I had cleaned it twice with cleaner thought I had it clean decided to use the pressure washer just to be sure wow, i just thought it was clean, this thing really did the job, next time I will just use the pressure washer. It starts every time, runs great, even after setting all winter when I went to use it this spring it started right up. Bottom line I would buy again! It's a little high priced but I guess you get what you pay for!!! May 13, 2014
Rated 5.0 out of 5.0 by Fantastic Product Piece of cake to assemble and start. Amazing power and speed of cleaning. You can do anything with these nozzles. The hose is cheap and burst on the 2nd day. It is too stiff. I had a longer heavy duty hose. The gas cap was missing a third of the plastic and is difficult to open until I receive a new one. The product starts easily and cleans everything. Don't use the narrow jets unless you really intend to strip.. The tanks for cleaning are a great asset. The wand grip is great. I cleaned years of stains form my drive in short order. I bought the 15 inch orbital attachment for large areas. Unlike my previous machine this one has the power to use that attachment very effectively. This makes large areas a snap. Great overall product will a lousy hose. Buy a new heavy duty before you start. April 21, 2015
Rated 5.0 out of 5.0 by Powerful Washer/Great Price I was debating whether to get the 2700-PSI or the 3100-PSI and I ended up going with this model for just 40 dollars more due to it being on sale. I definitely am glad I went with the higher PSI model, this power washer can take care of pretty much everything you need. It definitely has a kick to it and you can feel the power which is great! The only knock I have on the power washer is the cheap pressure hose that comes with it. It kinks easily and mine burst during the first use which was upsetting. I invested in a professional grade hose which is heat resistant and anti-kink(available at HD). The hose was a bit pricey $80 plus the attachments to make it compatible with this power washer, BUT it is definitely worth it. Overall this is a great product and with a better hose it would be perfect. Cleaned years worth of mud, stains, and mold from my concrete patio on its first use! Definitely worth the money.

Rated 4.0 out of 5.0 by Good Product Haven't actually used it yet, but have used similar products. The only thing I don't like is the removable tips. I prefer a wand with adjustable spray tip. April 28, 2015
Rated 1.0 out of 5.0 by Strike two From other reviews I knew to ship to the store and check for damage before accepting delivery. Sure enough, it had a dented gas tank and cracked gas cap. I refused delivery at the store. I reordered and requested extra packing materiel be added inside the top of the box (there is none whatsoever!). I was assured this would be done, but it was not. Fortunately, Washer #2 was not damaged. I got it home, oiled it, gassed it, hooked up the water and followed the starting instructions exactly. It wouldn't start. I suspected the carb was flooded so I let it sit an hour. I was then able to get it started, not easily, but it started. It ran for about 2 minutes, then the engine started running rough and it subsequently quit. I let it sit five minutes and the exact thing happened again, a bit sooner this time. Yes, there was sufficient water pressure, the choke was set correctly and the gas was premium grade and fresh (and I just used it to mow the yard). So, I packed the washer into the car and took it back to the store. HD took it back and issued a refund with no hassle. I'm debating whether to give it another shot. The two minutes it worked, it did exactly what I wanted. It had plenty of power. I'm impressed by the other reviews, so hopefully I just got a lemon. April 1, 2015
Rated 5.0 out of 5.0 by A great pressure cleaner for the homeowner After arrival from UPS, the unit was unboxed, and assembled in minutes. It started right up after two pulls and from there it went to work. This is an easy to use cleaner, even for my wife, and works great for any homeowner cleaning needs. We've cleaned gutters, walls, soffits, and are ready to take on a big screened pool enclosure. April 21, 2015
