Seven Years Later

Bought unit in 2013 and have used it to pressure my house one or two times every year since. House built in early 1900's with 12 foot ceilings. Gable peak at about 26 feet, perimeter about 50 X 60 and also washed my neighbor's house twice with it. This pressure washer gets a good workout! No major problems encountered, still starts on second pull even after winter storage. Only problem encountered, and minor in nature, is that to smooth out some surging I have to slightly engage the c...

Speed wash 3200psi, 2.5 washer

Would Recommend

[This review was collected as part of a promotion.] Received this pressure washer within 14 days delivered right to my door. Impressive little machine. First day was spent cleaning the driveway,two cars and playing around with the gadgets broom and tips that was included. Very impressed with ruggedness and ease at which this unit can be moved around. After installing one wheel and the handle into the frame then adding oil, she started very easily.

Good value

Would Recommend

[This review was collected as part of a promotion.] I was looking at this and a similarly equipped simpson model with a honda motor last year. The price dropped to the 400 dollar Simpson range this year. Both has quality engines and power but since this entire unit was made by generac I figured I would have no warranty issues. Some of the Simpsons came damaged and customers had issues with getting their machine fixed with the combination of motor, pump, and machine. It is nice that the unit ...

Just received it

Would Recommend

Just received this pressure washer today and put it together. It was very simple to put together. There is only one thing I did not like and that is, the lance is so long (a good thing) that it sets the nozzle in the dirt when hanging on the wand holding bracket (not a good thing). I have not used it as of yet and plan to do so tomorrow. Hopefully, exceeds my expectations. Great looking machine though.

Good product for the price.

Would Recommend

[This review was collected as part of a promotion.] Assembled the washer very easily and then set it up after reading the operating instructions. Started on the first pull after filling with oil and gas. Cleaned the driveway after the winter snow and dirt and does a good job. Will use to clean the patio and deck after it warms up. Seems to be a good product for the price range without being a professional model.

Smooth motor

Would Recommend

[This review was collected as part of a promotion.] This is the same base unit I have but an older model. Starts easily, I love the wand, it feels good in your hands, the hose itself seems cheap (I plan to purchase another) also should be at least 50'. Could have used quick connect fitting. Overall, I like the Generac brand and hope to have this one for several years.

Good!

Would Recommend

This is my review on Amazon I decided on this one because it has a brass horizontal pump. From what I have researched, the pump is the most important part of a washer, and the brass ones last the longest. Furthermore, this one is horizontal, so you don't need to get on your hands and knees to connect the water. Now..here are my thoughts- 1. Water broom is great..would be fantastic if they included an extension. For us taller people, you are hunched over using it. 2. How about more th...

Excellent Pressure Washer and accessories

Would Recommend

[This review was collected as part of a promotion.] TOP OF THE LINE PRESSURE WASHER AND ACCESSORIES! However in the interest of informing future owners and Generac, I am writing the following. After assembling unit as instructions written and filling oil in motor, the washer started up easily on the second pull. As it began to warm up, it began smoking like a brush fire, staved for oxygen. I shut it down and noticed black dirty oil dripping down on the muffler. I also notice oil sprayed on motor...

Great pressure washer

Would Recommend

[This review was collected as part of a promotion.] After looking at many pressure washers we decided to buy the speedy wash generac. Have only used it to wash part of the fence, but works like a charm. Will finish fence after home is washed and ready for paint. So far so good. Not too loud, pressure is perfect for fence and home prep. Light weight washer and super easy to put together. Great price point as well. Generac is a leader in the generators and looks like they have done well in this pr...

This Pressure Washer is Great for Homeowners

Would Recommend

I purchased this pressure washer after my Ryobi pressure 3100PSI died when it vibrated across the pool deck and fell into the pool. I like the Generac 7122 so much better! It's easy to start! I like the features! There is less vibration vs Ryobi. I believe it is the best choice for homeowners. I use this pressure washer at least 2 times a month. Washing my truck and company van with this pressure washer is fast and easy! I recommend this product.

Gave it a Tough Intro Workout

Would Recommend

After reading many reviews online about power washers, I selected this Generac 2900. I could not be more pleased! Once I got the washer home, I spent a few minutes reading the instruction booklet. My experience with power washers involves combat vehicles on wash-racks on military installations....NOT with gas powered transportable machines in my back yard, so for me reading the instructions was very beneficial. After getting the washer assembled - which was easy - I filled it with oil, gas,...

I bought a brand new pressure washer and assembled it out of the box per instructions. It looks great but will not start. I made sure there was gas, spark and air. It has never fired yet after at least 50 pulls.
