No unnoticed empty dispenser
In addition to illuminating the spray chamber, the integrated LEDs are also used to display error messages. When the canister is empty, the dispenser changes color to red and does not perform "empty strokes".
No sparks
The spray chamber is made of the highest quality Corian and is completely electrically insulated from the rest of the unit. This reduces the risk of a spark from an electrically charged person and a potential danger from the sprayed disinfectant.
