I believe Pre-Vacuuming sets us apart as Professionals, and the Hack who wants to rush thru the job and pad his wallet.
I too can try to believe my 400-500 PSI wand is removing the dry particulates, when in all honesty it is just pushing them into the primary backing, where once dry they release and continue to cause wear to the fibers at their hard to reach base.
Maybe once I get so busy that I'm doing way more jobs than I can handle in a day, stressing and running around to cut corners to get to the next job, I too will quit giving my customers a PROFESSIONAL service.

Residential Question to
IICRC
Question: What are the steps that I can expect a certified
professional to take when cleaning my carpet?
Answer: The principles of carpet cleaning are listed in the
S100 Standard and Reference Guide for
Professional Carpet Cleaning, last published by the
IICRC in 2002. The principles of carpet cleaning include:
Dry Soil Removal - thorough vacuuming using an upright vacuum with brush agitation and high-efficiency
double-lined collection bag, or a final filter, to remove up to 99% of particles at 1 micron.
Today now more than ever, pre-vacuuming is emphasized as a key principle when it comes to clean and healthy carpet.
The goal of the textile cleaner is to remove any unwanted matter that is foreign to the carpet's construction.
IICRC S100 states " ...
professionals must locate, identify, contain, remove and properly dispose of unwanted
substances from an environment or material." Dry particulate soil accumulates in the carpet. This dry soil left
to build up damages the carpet fiber creating abrasion/ shading issues which depletes the carpet life. A heavy
soil load present in the carpet can contribute to poor indoor quality.
Before professionals apply any moisture to a carpet, hair, lint, dust and particulate soils must be removed
by vacuuming. Professionals must vacuum carpet extensively in order to achieve carpet that is as clean and
healthy as scientifically possible.
Professionals should use the best-rated equipment to remove dry soil in carpets. Textile professionals should
be aware that pre-vacuuming sets the whole tone of the job. You must have excellent attention to detail; go
after the dust and lint around the carpet and in corners. Vacuuming all of the carpet exhibits the desire to
do the work correctly and to achieve above average results.
