Which carpet cleaning method is known for using less water?

The method that is known for using less water is dry cleaning. This carpet cleaning technique involves the application of a relatively small amount of cleaning solution that is mixed with a dry cleaning powder or solvent. The cleaning agent penetrates the carpet fibers and encapsulates soil and grime, allowing it to be easily removed with vacuuming.

In contrast, other methods, such as steam cleaning or shampooing, typically utilize significantly larger volumes of water, which can prolong drying times and may require additional steps to ensure that the carpet is properly dried afterward. Bonnet cleaning also uses moisture, though it is typically a surface cleaning method that involves a damp pad. The efficiency of dry cleaning makes it particularly advantageous for delicate fabrics or situations where downtime must be minimized, since it limits water use and the associated risks of over-saturation.
