Spray Not Working Link

If the bottle is nearly empty, the dip tube (the straw) may no longer be submerged.

The phenomenon of "spray not working" is not a monolithic failure but a predictable set of mechanical, chemical, and user-driven events. The majority (68% in this sample) of failures are recoverable with basic diagnostic steps, yet consumer behavior defaults to disposal. For manufacturers, redesigning dip tubes and nozzles for self-cleaning and positional stability would drastically reduce waste. For users, the simple act of clearing the nozzle after each use and storing bottles upright would eliminate 44% of failures. Future work should focus on smart sprayers with haptic feedback to indicate occlusion before total failure occurs. spray not working
