Self-cleaning features for extraction cleaners
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.
1. A system for cleaning a recovery path of an extraction cleaner having a fluid delivery system comprising a supply container and a recovery system comprising at least a suction source and a recovery container, the system comprising:
a wand, comprising:
a fluid delivery pathway adapted for fluid communication with the supply container and having a fluid connector; and
an airflow pathway adapted for fluid communication with the recovery container having an airflow connector; and
a wand cap adapted to partially receive the wand and comprising:
a fluid connector receiver that mates with the fluid connector of the wand;
an airflow connector receiver that mates with the airflow connector of the wand; and
an enclosed pathway between the fluid connector receiver and the airflow connector receiver.
2. The system of claim 1 wherein the wand comprises a wand housing with a first end adapted to selectively couple an accessory cleaning tool and a second end opposite the first end, wherein the fluid connector and the airflow connector are provided at the first end.
3. The system of claim 2 wherein the wand cap fits on the first end of the wand housing.
4. The system of claim 1 wherein the enclosed pathway comprises a first internal fluid channel in fluid communication with the fluid connector receiver and a second internal fluid channel in fluid communication with the airflow connector receiver.
5. The system of claim 4 wherein the wand cap further comprises a wall separating the first internal fluid channel and the second internal fluid channel, and at least one passage opening provided in the wall.
6. The system of claim 1 wherein the wand cap comprises a cap housing having a closed end wall and a peripheral side wall extending from the closed end wall to an open opposite end in which the wand is received.
7. The system of claim 6 wherein the wand cap further comprises at least one air vent formed in the cap housing and in fluid communication with the enclosed pathway.
8. The system of claim 6 wherein at least a portion of the cap housing is transparent.
9. The system of claim 1 wherein the wand cap further comprises a hose clip configured to clip onto an accessory hose of the extraction cleaner for storage.
10. The system of claim 1 , further comprising an accessory hose coupled with the wand and comprising:
a flexible fluid delivery conduit in fluid communication with the fluid delivery pathway; and
a flexible hose conduit in fluid communication with the airflow pathway.
11. The system of claim 10 wherein the wand cap further comprises a hose clip configured to clip onto an accessory hose of the extraction cleaner for storage.
12. The system of claim 1 , further comprising the extraction cleaner wherein the wand cap is provided on the extraction cleaner.
13. The system of claim 12 wherein the wand cap comprises a wand receiver on a housing of the extraction cleaner.
14. The system of claim 1 wherein the wand comprises a valve in the fluid delivery pathway for controlling the flow of cleaning fluid to the fluid connector and a trigger operably coupled with the valve.
15. The system of claim 1 wherein the wand comprises a detent and the wand cap comprises a detent opening configured to receive the detent to secure the wand cap to the wand.
