For the $, What surface cleaner is the best?

Scott Stone said:
Your calculation is wrong. You need 24 hp to push that much and not over tax the engine. The 18 hp engine is only good for 6 @ 3000PSI. There is a complex formula, but basically, it is the Number of GPM times the psi, divided by 1000. So, 6(3000/1000)= 18 or 5.5 GPM at 3500 PSI is ~19.25 hp.

As for the surface cleaners, the Landas have a lot of nice features, but I have gone to the 24 inch steel eagle with the aluminum deck. Dollar for Dollar, it is the best value.

I know from experience and this link. I run a 13hp 5gpm @ 4000psi and it runs fine. 18hp is enough to push an ARXWA8G35N with a 2:1 gear box at 1750rpm.
 
i like that machine russ johnson what surface cleaner is that?
 
That's a HydroTek ANTV3.
 
Mike,
after your insulting and ignorant PM to me, I will post here the exact same thign that I told you in response. Electric Brake Horse power and the horsepower measurement for a gasoline engine are two very different measurements.

http://www.generalpump.com/PDFs/SALES LITERATURE/60Series-brochure-lr.pdf

So pick out a pump number on this general sales brochure. You will notice there are two different methods of measurement for horsepower, EBHP (Electric Brake Horsepower) and GHP (gasoline horsepower) You can find the same pump, with the exact same specifications, except that the Drive for the electric pump and the gas pump are different, other than that, they are the same. I chose the TC 1507, since it is easily viewable on the same page at 100%. It takes 5.5 EBHP and it takes 8.32 GHP.

So, I will rest on my statement, you are wrong that they are the same. Electric horsepower is about 2/3's of gas horsepower. Thus, if you can run a pump on 18 hp electric, it actually translates to 24 hp gas.
 
There are lots of things that can be done. That does not mean it is right. And I will bet that you put them together yourself, too.
 
John your right .. I usually change tips on mine to get a little more gpm... My 13 hp on my TS 1511 ( Now with a nickel plated brass 2021 head on it ) Gets 3100 psi @4gpm ... I get about 2400 psi with a 0505 tip and a 1505 tip... Not sure but it seems to give me a little more GPM with the #5 tip verses the #4 recommended tip.

Here is a standard Home Depot Vac.. This is the one that I put the Pump in .. along with the check valve.. It works great and is able to suck up the water and pump it out fairly good.. Where would I go wrong using this for small jobs?

Also I cant figure out ( My Buddy's Idea ) why this doesnt work.. First we just cut a circle into the top of my homemade surface cleaner and mounted the vac hose up top and it sucked probably 50% of the water up... Seems like it should have done better. I also have an idea about mounting a plastic tube ring around the base of the surface cleaner with pick up holes in it that may work.. It looks to me that the whole object is to get the vac part of the surface cleaner as close to the floor as you can get it and keep a tight seal to the surface as well as catching the water that is actually moving around in the surface cleaner ..
 
John, Your pump puts out the same GPM at a constant RPM no matter what tip you have on it. This is taking into account you are using the correct size tip. So a 1505 tip at 2400psi = 4gpm is the same as 1504 tip at 3400psi= 4gpm. This is a rough estimate. Look on a chart to get the exact numbers.

Constant rpm = constant gpm
tip size change = psi change
 
Ok now this will freak you out good... Ok a 04 tip gives me 3100 psi @4gpm.. and a 05 tip gives me around 2400psi... Now when I put 2 --02 tips on my surface cleaner I get 3300 psi and when I put 2-2.5 tips on my surface cleaner I get 2800 psi and alot of steam... Hmmm .. We could say leaks or old nozzles or all of the above.. So I think my Whitco machine has ghost.... Now I have ordered a bunch of stuff for it that should be in today so I can stand out in the rain and install the stuff.. I got a new flow switch, new nozzles for everything, new wands, new hose, a new thermostat that I am going to have to rig up since my machine never had one to begin with, a new high limit switch... I really want to make sure my burner cuts on and off.. ( Long Story)
The reason I said more GPM is that a guy at A preesure washer place had a chart on nozzle size that I looked at ... But this could have been a gimmick since he was out of 04 tips at the time.. oh well waiting on UPS>.
 
Ok so what we did today is we took a stop watch and we ran a test .. We were working on the surface cleaner vac project but just out of curiosity ... I ran the machine with the hose open into a 5 gallon bucket and guess what before 1 minute was up it overflowed the bucket, Now with a 4 degree tip we almost filled the bucket up.. with a 5 degree tip we filled it up almost over flowing .. then we tried another new 4 degree tip and you guessed it we blew a hole in the bottom of the bucket..We had to use the lid on top for all of these experiments so dont try this at home...
Anyway my wet vac/ surface cleaner worked pretty good today ( IT REALLY SUX ) it picked up about 70 % of the water.. We are going to work on it some more Saturday..

Depends on how much power you have to push it. Here is a list of my suggestions.

13 hp 4gpm @ 3500 psi - 20 inch surface cleaner

13-20 hp 5.5-8gpm @3500 psi - 24-28 inch surface cleaner

26-33 hp 11-13gpm @3500 psi - 36 inch Maxima surface cleaner

I like the Whisper Wash surface cleaners the best. Always go with the two bar not the three bar setup. Use 15 degree tips for 20-28 inch surface cleaners and 25 degree tips for the 36 inch Maxima for the power recommended.

P.S. For some stupid reason the Maxima 36" surface cleaner comes with a 1/4" hose from the gun to the swivel. Take the hose and the gun off and replace them with a good 3/8" hose and a high pressure ball valve. Now you are ready to rock.

I have a Silver Eagle Whirly Bird 24 inch with 2 2.5 25 degree tips. Do you think that 15 degree tips would be too agressive on concrete. (My pw is 4000 psi and 5 gpm) I may get a set of 15 degrees to try out.
 
15 degree helps for really nasty concrete. I use to run 20hp 5.5gpm @ 4000psi with 25 degree tips and was having to double back for the really dirty/moldy driveways even when pre-soaking with straight 12% bleach and sodium hydroxide through my injector. I always take the injector off after pre-soaking to maximize flow.
