A self-emptying dock is the upgrade that makes a robot vacuum feel automatic: instead of emptying a tiny bin every day or two, you change a sealed bag every one to four months.
We rank on our hands-free score first (bag capacity, mop washing and drying, auto water refill), then value, navigation, suction and pet hair.

Docks are rated in days: 45–60 days is typical, 90–120 days is excellent. Real life depends on pets and home size.
