EXTRACTION WITH TEMPORARY SUCTION INTERRUPT

摘要

A method of cleaning a surface with an extractor having a fluid supply system and a fluid recovery system includes applying a cleaning fluid to a surface, applying suction to the surface to remove the applied cleaning fluid from surface, and selectively interrupting the suction to the surface for a selected time to increase dwell time of the cleaning fluid on the surface.

1. A method of cleaning a surface with an extractor comprising a fluid supply system operable to store a cleaning fluid and deliver the cleaning fluid to a surface and a fluid recovery system operable to remove the applied cleaning fluid from the surface and having a suction source, a suction nozzle, a recovery tank assembly, and a working air conduit between the suction nozzle and the recovery tank assembly, the method comprising:
applying a cleaning fluid to a surface; applying suction to the surface with the suction nozzle to draw the applied cleaning fluid from surface, through the working air conduit, and into the recovery tank assembly; and selectively interrupting the suction to the surface for a selected time to increase dwell time of the cleaning fluid on the surface; wherein selectively interrupting the suction comprises reducing the working airflow at the suction nozzle.
