How this ranking is built
We rank models by how often owners mention app / smart features in their comments. This list reflects real-world usage and satisfaction, not lab tests. App connectivity enables scheduling, no-go zones, and room-specific cleaning. Some apps offer advanced features like dirt detection and custom cleaning modes. Check if the app supports local control or requires cloud connectivity.
