i'm a 2 man team so allthough what you say is right for a one man, for 2 it doesn't work, man 1 walks in with sliders, followed closely by man 2 with hydraforce in hand, man 2 has presprayed half of 1 room when man 1 starts agitating, man 2 continues to prespray up to 3 rooms at a time while room one is ready to be extracted and man 2 is ready with wand and extracts. by time man 2 is on room 2, all 3 rooms have been presprayed and agitated and first room is ready for man 1 to edge with spray bottle (m/s).
3 rooms are easily and thoroughly cleaned in well under an hour. we've got this down to a "T" and in my eyes we don't cut corners.
so to sum up.
if you can understand the above your a bloomin genious
i don't half talk an incredible amount of bow locks sometimes.
seriously though if you did, by some strange reason actually follow what i said above, then dwell time is not an option for us.
as for mechanical agitation damaging fibres, like i said, hoovering a "dry" carpet everyday, is surely far worse than mechanical agitation on a lubricated carpet once a year. don't ya think?
