If the pressure washer is going to be doing multiple projects - washing down the house prior to painting, cleaning all the gunk that gets into concrete driveways that are almost always wet like in the Seattle WA area I used to live in, cleaning engine compartments and the engine, washing out sand out of carpeted floormats on the driveway, washing convertible tops, doing the first clean up- knock down of vehicles, prior to washing by hand, then I know a gas powered unit will last forever if you get a good engine, break it in carefully, change the oil periodically, and basically there is no maintenance on the pump which has it own separate oil..
I will go back and tell you which pump I have.. Forgot until you reminded me - my pump did start leaking a tiny bit around year-10 and I easily purchased a new one on line and R&R`d it quickly with no issues..
Since its been 6 years ago, I will have to try to find that file and tell you what pump I have..
It also has a Briggs & Stratton engine and it has never failed..
Also have a long wand on it with an adjustable V-type Fan Tip that is absolutely perfect for any kind of work.
You dont really need a very pointy sharp tip on there unless you want to see how quickly you can wreck things with it..
The V-shaped Fan Tip is way better, since its wider, it covers more area at a time, harder to accidentally hurt things with it..
You can always put the Fan Tip closer to things without hurting them if you are careful.
The sharp point tip will definitely make a hole when its placed closer to anything - hence, why I never use it..
