Which Methods Cleans Best?


Dry foam: The carpet cleaner applies shampoo to your carpet,
allows it to dry, and then, without rinsing, sucks the dried
shampoo into a vacuum. Can you imagine applying shampoo to
your hair, allowing it to dry and then removing the shampoo from
your head with a vacuum? This method leaves dirty residue in
your carpet, which is one reason dry foam is not too effective.

Absorbent pad (bonnet cleaning): This method is similar to dry
foam, except that the company sets a large cotton bonnet on your
carpet and with a floor polishing buffer machine on top ““buffs””
the carpet. The rotating motion causes the bonnet to absorb dirt
from your carpet. This method is also called bonnet cleaning.
Bonnet cleaning is like trying to use a large cotton towel or mop
to rub the dirt out of your carpet. It’’s not very effective.

Dry, absorbent powder: The dry-compound method spreads a
moist, absorbent powder through the carpet. The powder is
allowed to dry and then sucked into a vacuum. This method
leaves dry sponge particles at the base of the carpet yarn. And
because the carpet is not rinsed, this method is not very effective.

Hot water extraction: This is a fancy way of saying that a hot
water cleaning solution under high pressure is forced into your
carpet and then sucked out of your carpet.
In a recent Technical Bulletin, Shaw Industries, the world’’s
largest carpet manufacturer, ““recommends the hot water
extraction system, which research indicates provides the best
capability for cleaning. Combined with our RotoVac carpet
restoration cleaning system, the RotoVac patented vacuum heads 
use Rotary Jet Extraction which thoroughly cleans the carpet fibers
from all directions with hundreds of cleaning passes per minute. 
This system produces dramatically superior cleaning results with minimal 
drying time.
