Self-Emptying Dock
The Clean Base Automatic Dirt Disposal is the biggest everyday convenience here. It reduces how often you have to touch the bin, which is the kind of upgrade that matters most once the robot becomes part of a real cleaning routine.
That convenience has a cost in dock space and consumables, but it also changes the ownership experience in a meaningful way. If you want a robot that can disappear into the background for weeks at a time, this is the feature that makes the model feel more complete than a basic self-charging robot.
