what is your average sq. ft. per hour?

Hello,

I am trying to find out what everyone's sq. ft. per hour cleaning on concrete is so when I do some bigger jobs, I can time myself and see how I am doing. I have seen in some posts from 1000 to 2900 sq. ft. per hour. I am doing this by myself with a hot water, 3000psi, 5.6gpm machine with a 24" steel eagle. Please let me know how much you do per hour by yourself. Thanks.

most extreme 3500sq-4000sq ft hr on 3 month maintenance clean hot water 8gpm 28inch surface cleaner. on lower side first clean heavy dirt smaller areas with chemicals 1000sq-2000sq ft per hour.

Thats about right, for maintenance work.

always depends on gum.

Ok this may sound stupid but I been cleaning vent hods and concrete for about 14 years now and guess what BUBBLE GUM is easily eaten up by good old gasoline. . before cleaning spray the heavily bubble gum area with a little gas and went you get ready to clean it comes off like little rocks.. Might work for you it works for me about 80% of the time.
