Top 5 Types of Carpet Cleaning Methods used by Companies

While you have a lot of options when it comes to choosing a carpet cleaning company for your home or business, it’s vital to know the different types of carpet cleaning methods used by different firms, because not all carpet cleaning methods are suitable for your carpet.

The following are the various types of carpet cleaning available on the market:

Cleaning with Hot Water Extraction

Hot water extraction carpet cleaning, also known as steam carpet cleaning, uses high-pressured hot water to agitate the carpet fibers and dissolve dirt.

Cleaning using hot water extraction normally entails applying a cleaning product to the contaminated area, agitating the carpet with a brush, and then rinsing. After allowing the cleaning agent to settle in the carpet for a brief period of time, the carpet will be “washed” by carpet cleaning equipment to fully rinse the cleaning agent before being dried in a room or at an air conditioned temperature.

An average-sized carpeted workplace of 3000 square feet takes about 2 hours to clean and at least 4 hours to dry. Most cleaning firms recommend having the carpet cleaned in the late afternoon so that it can dry overnight and the office may resume normal operations the next morning.

Shampooing of carpets

Shampoo carpet cleaning was common until the 1970s, when encapsulation technology became available. While shampooing a carpet may appear to clean heavily soiled carpets, the technology’s disadvantages – leaving a large amount of wet foam residues in the carpet that takes a long time to dry, becomes sticky when it dries because no rinsing is done after shampooing, and rapid re-soiling of carpet – make it less popular than other cleaning methods.


Synthetic detergents are used as a basis for foam encapsulation, and when dry, they crystallize into powder form. When the applied cleaning foam dries, loose dirt particles in carpet fibre will be trapped into powder, and then vacuumed or brushed when the foam dries after cleaning.

When compared to carpet shampooing, the foam encapsulation cleaning technique has surpassed carpet shampooing since it consumes less water throughout the cleaning process, resulting in a faster drying time. Those that promote utilizing environmentally friendly products have given the thumbs up to foam encapsulation cleaning because it leaves less chemical residue behind after cleaning than carpet shampooing.

Although encapsulation carpet cleaning has showed good cleaning results, due to technological limitations, this cleaning approach has not been able to effectively clean heavy soiling carpets.

Cleaning Bonnets

This carpet cleaning procedure mainly involves cleaning the top section of the carpet fibre using a heavy duty motorised machine with a spinning pad that has been soaked in cleaning solution to absorb dirt from the carpet surface, resulting in a good surface cleaning outcome.

Bonneting is popular in hotels because it provides a quick fix option for cleaning carpet in high-traffic public areas that require carpet to be cleaned without a lot of wetness and to dry rapidly so that hotel guests are not inconvenienced.

Because bonneting does not thoroughly clean a carpet, dirt from beneath it rises to the surface in a short amount of time, leading the carpet to become filthy again quickly. Bonneting also causes chemical residue to accumulate in the carpet, since the heavy machine’s pressure on the spinning pad pushes the applied chemical and any remaining dirt into the carpet.

Carpet Cleaning (Dry)

Dry carpet cleaning, also known as compound cleaning, is a relatively new cleaning technology that has garnered increasing popularity and approval from leading carpet manufacturers due to its effective cleaning performance and lack of drying time.

Since the invention of dry carpet cleaning technology in the 1980s, a plethora of cleaning types and powders have been developed. Many people are skeptical about the effectiveness of this cleaning technique because it is relatively new compared to other traditional wet carpet cleaning procedures that have been trusted and utilized for decades.

The application of cleaning compound or powder into the bottom section of the carpet with a motorized counter rotating brush machine to open up the carpet fibre and allow the compound to settle inside, resulting in a thorough deep carpet cleaning outcome, is the highlight of dry carpet cleaning.

Cleaning compound is often constructed of biodegradable material that functions similarly to microsponges in that it can collect dissolved dirt in the carpet and be thoroughly removed at the end of the cleaning procedure.

Different dry carpet cleaning equipment manufacturers set themselves apart by establishing their own cleaning solution or powder formula and personalizing the design and operation of their equipment.

Dry carpet cleaning is safe for all types of carpets and is suggested for business workplaces that need to run 24 hours a day, seven days a week, as the carpet cleaning process does not impede office operations.
