Suction vs Mopping: What Should You Prioritize?
If your home has mostly hard floors (tile, wood, LVP) and you care about surface cleanliness: prioritize mopping — get the Narwal Freo X Ultra. If your home has significant carpet or you have pets: prioritize suction — get the Roborock S8 MaxV Ultra with its 10,000Pa and FlexiArm side brush for edges. If you have mixed floors and a budget under $800: the Roomba j9+ with its retractable mop solves both acceptably. Don't buy based on spec-sheet suction numbers alone — 10,000Pa at Roborock cleans differently than 10,000Pa at a lesser-known brand.
Self-Empty vs Non-Self-Empty
Every premium robot vacuum in 2026 comes with a self-emptying dock. It's not optional — it's the feature that makes robot vacuums genuinely low-maintenance. Without it, you're emptying a tiny dustbin every 1–2 runs. With a Clean Base (Roomba) or Auto-Empty Dock (Roborock), you empty every 60–90 days. The dock costs $200–$400 but is worth every cent. When comparing prices between models, always compare the bundle price (robot + dock), not just the robot price.
LiDAR Mapping vs Camera Navigation
LiDAR-based navigation (Roborock, Narwal) creates precise room maps and maintains them accurately in the dark. Camera-based navigation (some Roomba models) works well in normal lighting but degrades in very dark rooms. For 2026, the top-tier robots all use LiDAR as their primary navigation sensor with cameras added for obstacle recognition. The Roborock S8 MaxV Ultra uses 3D structured light (like a depth camera) specifically to identify obstacles — this is why it correctly identifies cables vs. socks vs. pet waste rather than just stopping at everything.
