I need to pressure wash my house. The exterior is vinyl siding and white
brick. The cost to rent a unit is $100 a day. I have seen some 1200 psi on
QVC for just a little more than that. Or should I consider buying something
more powerful? Thanks.
I bought one of them $100 units from Home Depot a couple weeks ago to
pressure wash the plaster in out swimming pool and it worked great, 110 v
operation and 4 gpm @ 1200 psi IIRC....
Sure beat the heck out of renting and then messing around with a big heavy
gasoline powered unit--especially since the job really needed nowhere near
that kind of capacity.
Graduation party this weekend. Wife said to get the house washed.
I have a 3.5 HP Honda and I used ZEP House wash from Home Depot. It did a GREAT job.
However, parts of my house is over 25 feet tall and this machine won't reach these
and I don't want to get on ladders. I'm borrowing my friends 11 HP Honda tomorrow and
will most likely do the job.
If you have a ranch or single story unit a unit like the ones other talked about will
you fine. Make sure you test the mixture of cleaner or you will stain the siding.
MAKE SURE YOU START ALL CLEANING ON THE BOTTOM AND WORK UP. Once you get streaking you
won't get rid of it. Don't let the cleaner dry and if its too strong you can etch your
Your assumption and my experience conflict.
With a good cleaner I have had good results with the higher pressure unit to reach
ft section. My results were good.. But as I said, I would not use the higher HP unit
More power, and you will blow the siding off. I would buy one of the
generic $100 units. It will help do the job, but you will just about have
to scrub every foot anyway or you will have streaks.
BUT you will be able to use the power washer on other things, like oil
stains on the driveway. Removing unwanted paint. All sorts of little jobs
you used to work at can be done easily and quickly by a power washer. You
don't need one that will cut steel, just a decent one that will last more
than two years.
Just did my siding with a 3.5 HP and a 11 HP unit. The siding is in great shape and
Of course, I had a competent siding installer, maybe that was the difference.
It seems that many here don't know that a 11 HP unit can be turned down in speed and
varrious tips to produce great results. If the guy needs or wants an 11 HP unit, go
it. You can adjust it.
I would buy one of the
Sorry I was unclear. My intent was to say that you don't need some mondo
sized sprayer. You can do it with just about any sprayer, but you have to
watch how close you come with the spray head, the spray pattern, and the
direction you shoot the water stream. Anyone who has used a power sprayer
learns this in the first thirty seconds. On most of my jobs, the sprayer is
actually a rinser, having had to do most of the scrubbing the old fashioned
way. Depending on the type of material cleaned, some still require that you
scrub every inch of it or it ends up streaked.
Buy a unit small electrics are slow but work good. Karcher is good. But
a Generac cheapie, well I blew 2 out in 4 hrs. By local incase it
breaks. Use a big unit, be sure you have and use a wide nozzle.

Wrong on both counts.
I use a 5.5 HP unit on my vinyl siding for three years. Also tried my
neighbors $100 electric before buying a gas powered unit from Northern
I never use any cleaner, just water. I can set the fan very wide and clean
fast, narrower for tough spots.
Vinyl will stay on just fine if one thinks just a little. Go with the
direction or overlap (don't shoot under the siding joints) and don't shoot
straight up. Basically, you can rip it off easily if you shoot the stream
under it - just pick your directions.
The lower power unit I borrowed also won't take the moss off my driveway
unless I go extremely slow. Again, the higher power allows a wider fan
setting and lets me get the job done.
One must be careful, set it to a stream instead of fan and it will bore
holes in a wood deck!

I think the smaller units work well. My experience is that they break
from not using it for a long time. (which would be in your case) so
follow the procedures in the manual about storage prep (drain it)

I think you're right to buy it outright. I bought a pressure
washer on Ebay, and it didn't have some parts. Bought
another one, and it didn't have some other parts. Bought
some parts. I finally figured it out, I had about $200 tied
up, and I coulda got one post paid for $89.97 from
(but it was a great learning experience. And I've used the
washer several times, and it's paid for itself.)
