Pressure Washer Recommendation

[Chip1wa]

A 4gpm machine with that Honda GX390 and 100' of pressure hose, a decent surface cleaner (Whisper Wash) and some basic knowledge and you can make $130-$180 an hour. For sizing a surface cleaner, don't buy the biggest one you can find. The rule of thumb is 4" for every gallon per minute. A 4gpm machine, you should use a 16" surface cleaner.
Charge by the job, not the hour.

I bought northerns 4/4 for 699.00 on sale, 899 regular. Thing is great, we soft wash, driveways, decks..... Just learn to use it and what tips you need for what job. We also have a 18" surface cleaner, works great.

I bought a Stihl RB 800 (their most powerful commercial model) and I am very happy with it.

It has the ability to put out enormous pressure - 4,200 PSI at 4 US GPM - but it comes with a pressure regulator to let you dial that pressure down. I normally run it at a reduced pressure, but occasionally I need full pressure for a particular problem such as paint on concrete, and it's great to have that higher pressure available.

I also suggest you buy a ripper nozzle (sometimes also called a rotating nozzle) - you won't need it all the time, but it is a huge time-saver when you do need it. Don't ever drop that rotating nozzle - they have a ceramic ball inside, if you drop it on a hard surface, the ball can shatter, and then the nozzle is junk. Treat it gently when it is off the wand.

I don't recommend Stihl's rotating surface washer - the one that @gchidest recommended in post #8 of this discussion would be a much better choice. Just be sure it is rated to handle the output pressure of the RB 800.

Thanks so much everyone!

I'm looking up on the sources Youngandfree posted, and I'm checking out all of the equipment suggestions y'all have made!

I love this site.

Going from a residential size Lowes bought 3gpm/ 6hp honda to the 4gpm was huge.
We all know the value of the local servicing dealer for our mowers-same can be said for the local power washer equipment dealer. If you have trouble with it-they'll service it. If you buy your machine from a box store-good luck.

You should not go any less the 4gpm, the time it will save you is worth the upgrade
