Abstract

Self-cleaning features for extraction cleaners and attachments for extraction cleaners, such as accessory tools, wands, and/or hoses, are provided. The self-cleaning features are configured redirect cleaning fluid from a fluid supply system of the extraction cleaner into a working air or fluid recovery path of the extraction cleaner, including, but not limited to into the working air or fluid recovery path of a tool, wand, and/or hose of the extraction cleaner.

Claims20

Dependent claims

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.

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;
a wand cap configured for attachment to the wand;
wherein the wand cap is defined by a cap housing having an end wall, and a peripheral side wall extending from the end wall to an open opposite end;
and
wherein the cap housing forms a cap fluid pathway when the wand cap is attached to the wand at the open opposite end of the cap housing, the cap fluid pathway directing flow of a cleaning fluid between the wand fluid connector and the wand airflow connector.
