Hey Sam,
Can't tell for sure what kind of floor surface you are cleaning, but I would use stiff floor broom, vac if possible, maybe even a shop vac (gonna go through a lot of filter bags), then sweep like crazy with a good stiff floor broom
Spray down a prespray and use the same stiff broom to help break the surface tension with that prespray.....
I like a hard surface wand with a brush as well.
Rinse and scrub. This one in the pics we just did this week we did at 800 psi because it was concrete, but you might rinse other surfaces with less psi. You will be able to tell by the amount of moisture you are loosing out the wand that could be more than needed loss.....
Also, you are going to go through filter bags....we use throw away paint strainer bags (5 gallon)
Not sure your going rate, but we charged .50 cents per square foot on this weeks, but looking at yours....It is going to be a lot more work!
Best wishes on the adventure, but you can get it done and make some money!
I'm getting the 5 gallon filter bags (that I make as throw away daily) from
http://www.painterdeal.com/filter.html
Get item SB-501...the other numbers are for the amount wanted....you can also get 5 gallon paint strainers from home depot, but they are 3 times the price in reality. The ones on the right are the Painterdeal units. Much larger!

Butler unit rear waste bag clean out
