4 nozzle single spray bar on Big Guy

I don't understand Pat, are you saying that you are not cleaning the concrete in 1 pass only? You are having to go back over the concrete and then a different direction just to clean moldy concrete? I am trying to understand what you are saying.

I like the conveyer belt material idea I bet it is more durable than a skirt. I think I will use it on my large surface cleaner cheaper than a skirt most likely.

It was free. A lot of plants that have conveyors often have pieces of old belts laying around. I would think if you talk to the maintenance super you could cut some off free or for a 12 pack.
 
Yeah, I thought of that. 15 minutes to dwell, ten minutes to clean the driveway! That driveway you are doing and the one that guy was doing weren't that dirty. Seems like the ones I get stuck with, look like they have never seen a pressure washer. Alot of them anyway. I love HOA's because usually the driveway was cleaned in the last year or so. That guy said his washer is 13 hp, 8 gpm...Hmmm??

Ever see this guy? He doesn't need a surface cleaner! This is unbelievable.

Look closely at the driveway, it is not even dirty, just some surface dirt, not moldy or the typical oil/grease that most of us wash.

I would like to see that method on a drive thru lane or something that we all call dirty.

Not dirty at all... The speed of the walk behind the surface cleaner is virtually the same dirty and 30 years old or cleaned 12 months ago..... the chem mix is different.
 
For residential I rarely pretreat prior to cleaning.
