Method of cleaning a carpet segment

摘要

The embodiments of the invention relate to methods of use of an extraction cleaning machine for cleaning a carpet segment of relatively rectangular configuration defined by a first edge, a second edge and opposite side edges comprising (a) applying a liquid cleaning solution to the carpet segment in a narrow band that extends between the side edges and moves between the first and second edges and (b) applying suction in a narrow band that extends between the side edges and moves between the first and second edges. Acts (a) and (b) can be repeated and performed in a predetermined sequence to improve the cleaning effectiveness of an extraction cleaning machine.
