Whats the matter?-- Josh Getting nervous?
Better get Rusty Britches on the phone and call out the Goon squad.

LOL
Hydra Tony, As far as equipment goes- Ive never had the need for a larger machine say 3-4 thousand PSI.
We've always used about 1600 PSI 2.3 GPM hot water upstream injection equipment.
I havent run into anything in 14 years I couldnt clean with it.
That includes the occasional piece of heavy equipment and decks.
Remember everything you put in the hood system you have to dispose of,its a heck of alot less water to pick up.(especially if your cleaning equipment inside) 2.3 GPM as apposed to 3-5 GPM and it tends not to get in your face so much. Ever get a return blast off a dirty surface from a 4GPM machine at 3200 PSI? it aint very nice!
The argument against smaller equipment is that it doesnt have the volume or flushing power. Or that it takes longer. Not necessarily true.
At the same time we are not servicing huge establishments.There I could see more power would be an aset,especially if your looking into doing building exteriors and such.
Alot of the guys use the bigger equipment. I also like the idea of a smaller electric drive motor, Alot less maintinance issues (no gas motor to fight with)
You can get some nice 3000PSI /220 machines. If you choose the bigger electrical equipment then make shure you get the different configuration plug adapters so you can find a place to plug in your equipment no matter where you go.
