Don't forget, most before and after pictures are the extreme.
99% of carpets don't actually look better in photo's. I once
removed a dustbin sized stain of beetroot completely, customer
absolutely amazed, as was I. trouble was before extracting I thought
I can't be ar*ed to fetch the camera, it won't look any different, big
mistake
.
Confidence will come with experience, and most cleaners become over
confident, when a brown trouser event knocks them back to where they
should be, confident but careful.
I used to train cleaners for a nationwide company many years ago, usually
3 to 6 months to reach the minor c&ckup that sets them properly on their way.
