An automated sprayer for spraying the walls of a shower enclosure with a liquid cleanser dispenses the cleanser using a pump and rotatable spray head. A motor drives the pump and rotates the spray head. The sprayer has a showerhead mountable housing with a hanger. The housing supports a bottle of cleanser in an inverted fashion. Cleanser is delivered from the bottle through a cleanser conduit in the piercing post into a well of the housing. The bottle is vented from the well through an air vent path in the piercing post or from a well vent outlet through the air vent path in the piercing post. An outlet valve in the well permits outflow of cleanser from the well. Various bottle caps and bottle closures are also provided to improve venting and/or limit cleanser leakage from the bottle when the bottle is installed in the housing.

What is claimed is: 1. An automated sprayer for spraying an enclosure with a liquid cleanser, comprising: a bottle suitable to contain a liquid cleanser; a reservoir tray having an upwardly extending well for supporting the bottle in an inverted orientation; a spray head having an outlet orifice through which cleanser from the bottle can be expelled if there is such liquid cleanser in the bottle, the spray head being in fluid communication with the well; and a piercing post extending from the reservoir tray into the bottle, the piercing post including a cleanser conduit in fluid communication with the well for delivering cleanser to the well and an air vent path separate from the cleanser conduit, wherein the well includes a chamber for holding cleanser delivered to the well and a valve for controlling outflow of cleanser from an outlet of the chamber, the valve being located downstream of the piercing post. 2. The sprayer of claim 1 wherein: the air vent path is in fluid communication with a vent outlet of the well. 3. The sprayer of claim 2 wherein: the vent outlet of the well is in fluid communication with a check valve such that cleanser does not leak out via the vent outlet of the well. 4. The sprayer of claim 1 wherein: the air vent path is in communication with an air passage between the bottle and an inner surface of the well. 5. The sprayer of claim 1 wherein: the valve is a spring-loaded outlet valve that permits outflow of cleanser from the well when a portion of a cap of the bottle abuts against the outlet valve when cleanser is in the bottle. 6. The sprayer of claim 5 wherein: the outlet valve includes a valve stem that moves toward the bottle to permit outflow of cleanser. 7. The sprayer of claim 6 wherein: the portion of the cap that abuts against the outlet valve is a section of the cap that projects axially from the cap. 8. The sprayer of claim 7 wherein: the air vent path is in fluid communication with an air passage including a channel extending through the section of the cap and an air flow path between the bottle and an inner surface of the well. 9. The sprayer of claim 1 wherein: the bottle has a cap having axially projecting segmented ridges, and the valve is a spring-loaded outlet valve that permits outflow of cleanser from the well when a portion of at least one of the segmented ridges of the cap of the battle abuts against the outlet valve. 10. The sprayer of claim 1 wherein: the valve includes a valve stem that is spring-biased in a normally closed seated position that seals the outlet of the chamber and the valve including an actuator that unseats the valve stem from the outlet of the chamber when a portion of a cap of the bottle abuts against the actuator of the valve. 11. The sprayer of claim 10 wherein: the actuator comprises a plunger in contact with a rocker that unseats the valve stem. 12. The sprayer of claim 1 wherein: the cleanser conduit terminates at an opening of the piercing post, the air vent path terminates at another opening of the piercing post, and the opening of the air vent path is at a position further into the bottle than the opening of the cleanser conduit when the bottle is installed in the inverted orientation in the tray. 13. The sprayer of claim 12 wherein: at least a portion of the opening of the cleanser conduit is located in a side wall of the piercing post. 14. The sprayer of claim 1 wherein: the cleanser conduit terminates in an opening at an end of the piercing post, the air vent path terminates in another opening at the end of the piercing post, and a wall extends outward from the piercing post between the opening of the air vent path and the opening of the cleanser conduit. 15. The sprayer of claim 14 wherein: the wall has a curved chisel top. 16. The sprayer of claim 1 further comprising: a gasket, wherein the gasket is configured to seal against the piercing post when the bottle is installed in the inverted orientation in the tray. 17. An automated sprayer for spraying an enclosure with a liquid cleanser, the sprayer being of the type that receives a refill bottle containing the liquid cleanser, the sprayer comprising: a reservoir tray having an upwardly extending well suitable for supporting a bottle in an inverted orientation when the bottle is inserted in the tray; a spray head having an outlet orifice through which cleanser from the bottle can be expelled if there is such liquid cleanser in the bottle, the spray head being in fluid communication with the well; and a piercing post extending from the reservoir tray into the bottle when the bottle is inserted in the tray, the piercing post including a cleanser conduit in fluid communication with the well for delivering cleanser to the well and an air vent path separate from the cleanser conduit, wherein the well includes a chamber for holding cleanser delivered to the well and a valve for controlling outflow of cleanser from an outlet of the chamber, the valve being located downstream of the piercing post. 18. The sprayer of claim 17 wherein: the air vent path is in fluid communication with a vent outlet of the well. 19. The sprayer of claim 18 wherein: the vent outlet of the well is in fluid communication with a check valve such that cleanser does not leak out via the vent outlet of the well. 20. The sprayer of claim 17 wherein: the air vent path is in communication with an air passage between the bottle and an inner surface of the well. 21. The sprayer of claim 17 wherein: the cleanser conduit terminates at an opening of the piercing post, the air vent path terminates at another opening of the piercing post, and the opening of the air vent path is at a position further into the bottle than the opening of the cleanser conduit when the bottle is installed in the inverted orientation in the tray. 22. The sprayer of claim 17 wherein: the cleanser conduit terminates at an opening at an end of the piercing post, the air vent path terminates at another opening at the end of the piercing post, and a wall extends outward from the piercing post between the opening of the air vent path and the opening of the cleanser conduit. 23. The sprayer of claim 22 wherein: the wall has a curved chisel top. 24. The sprayer of claim 17 wherein: the valve is a spring-loaded outlet valve that permits outflow of cleanser from the well when a portion of a cap of the bottle abuts against the outlet valve when the bottle is inserted in the tray and cleanser is in the bottle. 25.
