Answer: 
What they don"t tell you is that if it is not CARB certified your engine will run better because it runs less lean. The CARB carburators do not have any way of adjusting them if you need to. I buy non CARB equipment when possible.

Answer: 
CARB is an acronym for California Air Resource Board, whose stringent air-quality standards have been adopted by many states. A Non-CARB Compliant Engine fails to meet these standards. While CARB-compliant engines run cleaner than non-compliant models, they still emit pollutants.

Answer: 
When a product is CARB-compliant it conforms with the air pollution requirements set by the California Air Resource Board (CARB). These products will operate with less pollutants than non-CARB compliant generators. The Generac 3100-PSI 2.8-GPM OneWash Variable Speed Gas Pressure Washer does not meet these standards.

Answer: 
The pressure is changed by both changing the speed of the engine and the different nozzles that come with it. I just bought one today and used it to clean my house and my car. Very nice machine and I recommend spending the extra money on this one.

You'll probably need a gun extension to reach the upper floors while standing on the ground. REMEMBER, the pressure at the end of the extension will be the same as it is at the end of the gun without the extension. In hydraulics, pressure out equals pressure in. DO NOT USE A LADDER!!!

Gun extensions are sold as after market items in the Home Depot and other suppliers. They should do a satisfactory job of cleaning the 2nd floor, but I'm not sure if they will work on the 3rd floor because the pressure at the extension outlet may be too much to handle while working from the ground. Professional workers use scaffolding for upper levels. Pay attention to the pressure rating of the extensions! They should be rated for at least 3,100 PSI service. Read Less

Rated 4.4 out of 5 by 627 reviewers.
Rated 1.0 out of 5.0 by Very bad experience I struggled on which pressure washer to chose. After talking with a friend of mine who owns a Generac, and loves it, I settled on this one. I read a few of the poor reviews talking about oil leaks, but I saw this happened on other brands as well. So what were the chances? Got it today, put oil in it, gassed it up, hooked the water hose up and turned the hose on. Then fired it up. After about 5 pulls, she started up to white billowing smoke and oil spraying everywhere including my concrete driveway, my leg, and all over the unit. Looks to be leaking around the seal on the valve cover. It was flat pouring out of there. So I will be returning it to Home Depot in the morning and I guess buying the Ryobi. Just really disappointed. September 6, 2016
Rated 5.0 out of 5.0 by Great Pressure Washer This pressure washer was easy to assemble right out of the box. It starts on one pull almost every time. I used to it to clean various items such as lawn furniture and wooden bridges and have yet to find anything that it would not clean. The machine is so powerful you need to be careful what you use it on and to test a inconspicuous spot. The pressure washer on high can easily pull the grain up from wood if you go to close. The soap siphon also works well and gives good coverage of soap onto the item being cleaned. The only con is the clip to hold the hose could be built with a better design, rolling up the pressure hose is sometimes clumsy and hard to get organized. June 28, 2016
Rated 5.0 out of 5.0 by Really a nice pressure washer The product works great and is easy to start and use. I like the interchangeable nozzles and the front storage system for them. The only drawbacks I have found so far are the hose is pretty stiff and hard to coil and uncial and the front panel is flimsy especially where one would put their hand down when trying to pull start the unit. It starts really well though so its just a matter of not resting your hand there. I like that you can easily just use a bucket for soap or use the attached container if preferred. The variable pressure settings are really nice too so one doesn't take the paint off the boat, (unless you want too). June 8, 2016
Rated 5.0 out of 5.0 by STRONG AND POWERFUL. WORTH THE MONEY. Most of this power washer unit was already put together in the box. Easy to complete myself with very few tools. I am very impressed with the power this unit has. I had another brand that was damaged in our last flood so I bought this unit from Home Depot. I read the reviews first on many brands and this one looked the best for the amount of money being asked. My older one was a 2200 psi gas unit so I thought I would gain just a little more power than the last. This new unit was way more powerful with the ability to move over the area faster. Great and fast coverage. I would suggest buying this pressure washer to anyone. August 30, 2016
Rated 5.0 out of 5.0 by Awesome Pressure Washer I did extensive research before making my purchase of this generac pressure washer and it paid off. This thing is amazing! The negative reviews are probably coming from those who didn't follow the directions on initial setup. Two minor critiques: 1) the on/off switch was disconnected upon arrival and was a little tricky to get my hand in the right place to connect. 2) they should provide only the amount of oil needed for initial setup. I overfilled because there is no way of determining how much it takes unless you pour a little and check a dozen times. I had to siphon some oil out to be at the right amount. As for performance.... As good as advertised. August 23, 2016
Rated 5.0 out of 5.0 by Should have bought it sooner. The choke pull button was frozen stuck on arrival !! I called Generac service dept the next day - and had no problems getting advice, contrary to what I had read in some reviews - but decided to tackle it myself with brute force and penetrating oil. That was only a minor issue. Their manual rightly emphasizes safety at every turn. I have used it several times since. It's almost effortless. The convenience of a large built-in soap container is a big plus. All my walkways and patios are sparkly clean. My deck will be a cinch, but the next really big project will be getting the 3-car garage ready for cleaning. August 9, 2016
Rated 4.0 out of 5.0 by To be determined Tried for more than an hour to start it for the first time, and got very frustrated. I tried many different things to start it and finally decided to try draining the bowl on the carburetor. The bowl was full of oil. Somebody at the factory probably got a good laugh out of that. After draining the oil out it started on the second pull and the engine ran beautifully.. I have never used one of these before, but my son had and was very impressed by the power it has. He is going to paint a house in a couple of weeks, and use the pressure washer to clean the house first. I should have an opinion on its usefulness after that. August 9, 2016
Rated 5.0 out of 5.0 by The best friend you can have for the house... This is my first time owning a water pressure and I'm glad I chose the Generac OneWash model #6602. This machine has all the features I was looking for: easy to start, easy grip on the gun sprayer, assortment of nozzels, can be set to different power levels not just one like other brands, has the compartment for the soap mode and a drainage as well, easy for routine maintenances that make this machine last for many years to come, etc......I was very impresed with the simplicity and the power of this machine. Cleaning my drive way was fun knowing I was backed by this great Generac machine. This is just the beginning of many projects I have line up, next will be the fence, roof, outside house's walls, patio deck and my wife's car and mine of course. Without a doubt, I will recomed this machine to anyone who want to give a fresh clean look to your house. [This review was collected as part of a promotion.] August 14, 2016
