Surface cleaner spray nozzles

What is your favorite nozzle for concrete a 15* or a 25*. I've been using 15* for some time now and I am beggining to feel they are a little too aggressive. I'm wondering if switching back to 25* might help eliminate striping issues and clean a little more evenly.

Great weather Pat. My son was sore from helping me PW 150 yards of vinyl fencing yesterday. He wanted to get home & soak in the hot tub instead of riding south. Darn kids nowadays don't know what work is. He wouldn't last 5 minutes in a house fire with me!
 
Surface Cleaner nozzles should be "relative to" the deck, and surface being cleaned..
21" deck with 4gpm.. 15 degree, or you won't have enough "clean" at the surface (..unless you have 230+ degrees).
21" deck with 6.5gpm @3500 psi.. 25 drgree you clean like heck, and go 2 times faster than 4gpm.
21" deck with " with 4000psi.. use 40 degree for crazy workspeed, and less striping.
With 8gpm.. go to 30" surface cleaner, with 3 nozzles at 8gpm,
..or 4 nozzles at 12gpm
Hmmm.. I'm doing one of those with a diesel engine currently..12gpm @ 4000 psi

Anyway..
too much pressure is bad,
wasted gpms is sad,
not investing in heat can be a waste,
mis-use of chemicals is in bad taste.

The jobsite tells you what it needs..
..The better you "read the site", the more profitable it can become.
Adjusting the tools for every site might just be the next level of finesse you need, to maintain competitive edge,
and creatively expand your services.

Guys..
try to tell us what gpm, temp you use in what size deck, and for which surfaces..
It is all relative for an opinion to be helpful .

What he said.

I personally prefer 25 or 40. I use the Landa Water Jet and adjust it for what I'm cleaning. I only use 15 degree tips if I'm acid washing or stripping paint off concrete. Even then though I'll normally stick to my 25's or 40's.

For the fastest work speed I use 40's and angle the tips a little bit away from the concrete. Landa is 1/3 way up. By angling the tips away from the concrete you increase the width of impact and make the bar spin faster. Use a good degreaser and we can do easily 6500' an hour with a 20" surface cleaner.
 
And I like the bars spinning fast like Craig said. I think the bar speed may be the biggest factor, I tilt the nozzles a bit more.
 
I am not sure if most or all manufacturers have the spray nozzles at the same angle, I am wondering if anyone has tried different brand spray bars on their surface cleaners.

Like a mosmatic spray bar on a whirl a way or a Whisper Wash spray bar on a Steel Eagle surface cleaner or something else and what the results were.

I was wondering if the whisper wash aluminum spray bar from the 24" surface cleaner would fit the Steel Eagle 24" surface cleaner and if it would spin faster than the steel pipe spray bar that the Steel Eagle has?
 
I run all 10 gpm machines and I have always used 25/5 tips with great results, 15 is to aggressive.
 
I have always had trouble with stripping and couldn't figure it out, but I do believe this is the problem.

We are running 8GPM and 15*. Think I will try 25*
 
good to see yer all gettin the hang of this !

more nozzles get less zebra stiping, wider nozzles too,

wider is faster, and narrower spray angles clean more agressively.

DON't mess with rotor-speed.. the factories typically balance the spraybars for about 2000 rpm.s
..a steeper spray-angle against the spray bar is less impact on the surface, and faster-spin is more wear on the swivel.

one more thing..
GET A FILTER on the inlet of the swivel, and it will last longer.

..come to my Pressure Washer BulletProofing class ..I'm telling you.. you'll leave with great info.
 
I have a fixed angle Mi-T-M and I am trying to figure out a place to buy tips. Any advice?
