Figure of speech, saying "same results"
I was meaning that in reply to your comment about getting the end product the same (with the same amount of soil removed)
I actually don't believe wetting all that dust/sand/etc first, is good. I would bet, it will be a cleaner result if you dry vacuumed most of that first before introducing moisture.
Just because Barry Costa taught there is more than one way to get things done, doesn't make all of them the right way. You can change oil in a car, by sucking the oil out through the fill opening instead of removing the drain bolt. It's going to be the same end result...
Anyways, I don't mean to argue over the merits of vacuuming before cleaning. This has been discussed over and over again.
