Cleaning Methods
Combination of Hot Water Extraction and Shampoo:
As the name implies, this method uses the Hot Water Extraction method and Shampoo. This method is specially effective for cleaning highly soiled carpets, with heavy oil/soil build-up.
The process has two steps::
- Shampoo using rotary brush to loosen soil
- Hot Water Extraction using water rather than detergent solution to remove shampoo
Some units may combine both steps. It is usually expensive because of added labor costs.
TIP: For residential cleaning, Hot Water Extraction on it's own is usually powerful enough to clean most carpets.
