You have just illustrated, inadvertently, living proof that cleaning in a particular style, is NOT muck spreading, as suggested by some whe can't see beyond HWE.
The principle you've shown so effectively, is vitually the same as the, popular, particularly in the US and Canada, method of cleaning carpets by encapsulation, and O/P machines.
I don't doubt there will be a negative response to this post, but I've been experimenting for a couple of years and Padman in America has a growing fan base of converts / users.
