1. A system for cleaning a recovery path of an extraction cleaner, the extraction cleaner having a fluid delivery system comprising a supply container and a recovery system comprising a recovery container, the system comprising:
a wand fluidly coupled with the fluid delivery system and the recovery system, the wand comprising:
a fluid delivery pathway adapted for fluid communication with the supply container and having a wand fluid connector; and
an airflow pathway adapted for fluid communication with the recovery container and having a wand airflow connector; and
a wand cap configured for attachment to the wand, the wand cap being defined by a cap housing with a cap fluid connector and a cap airflow connector; and
wherein the cap housing forms a cap fluid pathway when the cap fluid connector is fluidly coupled with the wand fluid connector and the cap airflow connector is fluidly coupled with the wand airflow connector, the cap fluid pathway directing flow of a cleaning fluid between the wand fluid connector and the wand airflow connector.
