Auto empty using central vac idea

Build an optional charging station that could connect to a central vacuum system. Use this to auto empty the cup. Central vacs are not universal in every house but if you have one, the interface to the hose and ‘on-switch’ usually is universal, and integrated. All that would be needed is a short length of hose. And there would be an outlet nearby to plug the charger into. It might take some adaptation for the charger to hook to the vacuum and the vacuum itself to empty the cup, But what a feature. No dealing with emptying every charge. And central vacuums have really strong suction. It would clean it out well. A single empty point with much larger volume. No touch emptying.
