Pros and Cons of Carpet Cleaning Methods
Today, many professional carpet cleaning businesses and individuals utilize a variety of carpet cleaning procedures. Each method of cleaning has its own set of unique benefits and drawbacks. This article will help you select among them by tabulating the most common approaches and outlining their perceived benefits and drawbacks.
Carpet cleaning procedures may be divided into two
categories: wet cleaning and dry cleaning. Wet cleaning entails using hot water
extraction as well as an absorbent pad to clean. Dry carpet cleaning is the
application of chemical powders or foams by specific equipment equipped with
counter-rotating brushes, pads, or cylinders.
Cleaning with Water
(a) Deep Steam Cleaning Or Hot Water Extraction
To saponify or liquefy any soils or oil-based compounds that
may be present, the carpet is first pre-conditioned with a chemical reagent.
Water at near-boiling temperature and pressure of 50 to 500 psi are then
injected into the carpet, and the resultant solution is removed with a vacuum
of 5 to 14 inches HG after an appropriate dwell time (typically 10 to 15
minutes).
PROS
Removes soiling from deep inside the carpet.
High temperatures, pressures, and chemical concentrations are
permitted.
Allows for longer dwell periods for cleaning solvent
reaction.
Agitation with a grooming tool or extraction brush promotes
chemical reactions.
This is the approach most commonly suggested by carpet
producers, as well as cleaning specialists and professionals in the business.
CONS
The drying time is rather long. This can be decreased by
employing strong equipment and skilled experts.
For optimal efficiency, expensive equipment is generally
necessary.
Cost considerations that are rather high
(b) Using an Absorbent Pad to Clean
This procedure, sometimes known as bonnet cleaning, is often
employed for routine light maintenance, but it is also utilized for regular
carpet cleaning. After vacuuming the carpet, a chemical solution is sprayed
over it using a hand pump or electric sprayer. The solution is left to dwell or
react on the carpet for the appropriate amount of time. The towel-like
absorbent pad or bonnet is put on the drive block of a rotary floor machine and
spun over the carpet surface at 100 to 300 pm. This process impregnates the
carpet fibers with the chemical solution, which is then picked up by the soils. (
PROS
Fast. Simple. Inexpensive.
With lightly dirty carpets, the results are excellent.
CONS
The upper one-third of the carpet fibers are only cleaned.
Incapable of delving further.
Dirt and chemicals are left to build at the bottom of the
carpet fibers, close to the backing.
Cleaning Services
(a) Using an Absorbent Compound to Clean
A powder containing specific solvents and cleaning chemicals
is applied to the carpet and pushed into the fibers using a special machine
equipped with counter-rotating brushes. The powder collects dirt and is left on
the carpet for 10 to 15 minutes before being cleaned away.
PROS
The system is really simple. There is no need for any
specialized technical training.
Very quick drying. It will take around 20 minutes for the
carpet to be ready for use again.
CONS
The powder may become trapped in plush pile carpets and
accumulate over time.
Typically produces an excessive amount of dust in the indoor
environment.
Inability to deep clean the carpet (b) Dry Foam or Rotary
Shampoo Method
To create a solution or suspension of soils, a foamy
surfactant is sprayed to the carpet, which is then whipped into a foam and
pushed into the carpet fibers with the spinning brushes of specific
equipment. The foam is removed with a vacuum after a brief dwell period.
PROS
Fast. It is simple to use. Inexpensive.
These spinning brushes provide excellent agitation.
Carpet dries quickly due to the little amount of moisture.
CONS
Unable to accomplish comprehensive dirt extraction under the
carpet's surface.
High temperatures are seldom attained.
Excessive wetness is possible if the device fails.
Brushes may harm carpet fibers, especially when they are
fresh.
You should weigh the benefits and drawbacks of each approach
before selecting which one to employ to clean your carpet.
