good machine
we have used this washer a few times so far. mosty for dirt bikes and trucks. runs great, good pressure for cleaning around the house. i was looking at a different unit and the guy at CPO recomended this one. so far so good. generac needs to redesign the fuel cap, difficult to zip on and off with ease. other than that, works great!

Works great
I gave it a 4 because nothing is perfect. Assembly was easy and it started right up. I like the choke instead of a primer bulb. The handle is easy to hold and the spray trigger is easy to pull. One thing I don't like, is the same with most preasure washers at this price range, the hose hangs down and gets caught under the wheels when moving the washer.

Used, not reconditioned
I just sent back my 2nd "reconditioned 2700 psi power washer (must say: great CPO return policy). The first was missing the hose hook and one nozzle and looked really "used". The second looked just as "used" and had hole in rusty water inlet screen as well as a heavy alkaline build-up inside the inlet. I decided to buy a new one. All my other purchases from CPO have exceeded expectations. I will continue to buy from them.

Started right up but had missing parts
Extremely easy to start, but spray heads do not attach easily and pop out when spraying if not set just right. Has good power.

The best I have owned
Easy to operate, lots of power, very reliable. I use this to clean just about everything outdoors, it even removes paint!
Caution must be used when selecting the proper nozzel or you can damage the surface of items easily.

Very nice power washer--
The 2700 psi is very powerful--and the 2.3 gpm supplies plenty of cleaning action. There maybe better on the market but for the price this is a great power washer. I am very well pleased with this purchase.

One of the best tools I have ever bought
I ordered this pressure washer on a Friday afternoon. It arrived Saturday at 10:00 AM. I assembled it, per the instructions, and was pressure washing by noon. I used this washer 3 days in a row for about 5 hours each day. Never had a problem. Used it again the next week for 3 more days and washed my decks. Again, never a problem. This is a well built and dependable machine. I have many more uses for it... in the future.

I have a 2700 psi Generac washer, works well and starts right up. With the proper spray head installed
and cleaner in the detergent tank, I am not able to siphon the cleaner out of the tank. The hose is
submerged but the pump is not picking it up. What is my problem?
