Self-Emptying Base
The base is the main reason this model earns its hands-off reputation, because it can hold up to 30 days of dirt and debris and empties after each clean. That matters if you want fewer dust-bin chores and a cleaner routine around pet hair or frequent floor use.
The trade-off is that the dock is part of the experience, not just a storage stand. It adds convenience, but it also adds noise during emptying and another piece of hardware that needs space near an outlet.
