Navigation beats raw suction in real homes
For most US homes, a robot that maps rooms reliably and returns to finish a job is more useful than one that only advertises a bigger suction figure. LiDAR-style mapping is usually predictable in dark rooms, while camera-assisted systems can be better at recognizing socks, pet bowls and cords. If your floors are usually clear, a simpler mapper is enough. If the robot must clean under a dining table, around toys or near charging cables, obstacle handling should be near the top of your checklist.
