My experience with pressure washers is bigger is better. Look closely
at the GPM rate of the pump in addition to pressure. It takes both to
clean off built up gunk.
The best money I spent was on a rotating nozzle. There is no comparison
to how well it does versus the straight nozzles. I bought my nozzle at
Northern Tool and it was about $100 for the nozzle alone. Not only does
it do a better job in cleaning, it is also faster than the straight
nozzles.
You might also check with Northern for a pressure washer. They have a
very wide selection and I would recommend one with a Honda engine and
CAT pump. They are industry standards and you can get replacement parts
for both the engine and pump. I had a Karcher pump with a 10hp Honda
and the pump failed. I replaced it with a CAT pump and have been very
pleased with its performance.

A 3800 should work well for the sidewalk. I got a 3000psi to work on the
sidewalk mildew. The mildew turns the sidewalk black. I got five nozzles
with mine. The one that works best for everything is the turbo rotating
nozzle. Same nozzle worked well for removing the paint on the house.The
other nozzles just use up fuel and annoy me. :) The lower psi
pressure washers that I borrowed didn't work for me. Degreasing also
works good, but for the grime that's been sitting a while, a steam
cleaner works much better. You're going to get a lot of splash back when
working in the engine compartment even at the lower pressure settings.
Cost for the unit was around $500 at Lowes years ago. Mine is very
noisy. I use ear plugs, real goggles instead of my glasses only and a
dust mask for the water spray. Look like a nerd but, safey first.
Amazing what it can do the asphalt driveway if I'm not paying attention.

I am in need of a pressure washer and am looking for suggestions. What
I have
in mind so far, just to give you an idea of the size I had in mind, is
a 3800
psi 4 gpm minimum. I have been eying the Dewalt GX390 for 999.00 at HD.
It's
portable enough to get around but yet powerful. My research so far
tells me
you need at least a 4gpm minimum to move the grease, a separate pump as
opposed to one the engine sits on and either a Honda or Briggs motor.
It
will be used mainly for cleaning side walks and degreasing cars and
tractors,
Thanks for the advice.
