Most dirt and stains are embedded in the carpet fibres, so just waiting to be released. Vacuuming can remove surface dirt but cannot remove the embedded dirt and stains.
Hot Water Extraction Goes Deep
A professional carpet cleaning service uses hot water extraction machines to force hot water and cleaning solution down into the carpet pile, beneath the fibres and into the spaces where dirt has accumulated. As the solution passes through the fibres, the grime is lifted out of the carpet and carried away in the rinse water.
Pre-Treatment Breaks Up Compacted Soil
Pre-Treatment work allows the solution to penetrate the carpet fibres and agitate the soiled area. This work can be carried out using a brush or pad to lift the matted fibres to allow for a thorough rinse of the area.
pH-Adjusted Detergents Release Grease
This kind of dirt is greasy and attracts dry soil, so it needs to be broken down by an alkaline solution. The subsequent acid rinse can then return the pH of the fibres to its natural value. This prevents the fibres from getting dirty again straight after the cleaning.
Dwell Time Matters on Stubborn Patches
Cleaning of carpets with heavy soil, can require the pre-treatment solution to be left on the carpet for several minutes before rinsing off. During this time, the solution penetrates and the soil is loosened. Results on very dirty carpets are often excellent after a delayed clean.
Extraction Removes Dirt Rather Than Spreading It
Removing dirt and moisture from the carpet as part of the cleaning process, rather than allowing it to resurface as dry dirt or evaporate as part of the left over water, is what really sets a professional carpet cleaning service apart from the rest.

This is why professional carpet cleaning is far more able to reach the depth of your carpet than a domestic vacuum cleaner and a vacuum cleaner.
