Understand the limits before you buy
Navigation determines how efficiently a robot vacuum cleans and how often it gets stuck. Use this checklist to understand the difference between simple navigation and advanced obstacle avoidance.
Navigation differences
- Obstacle Avoidance: Premium models with cameras or advanced sensors handle unexpected items (like cables or shoes) better, but no model is completely immune to getting stuck.
- Simple navigation (bump-and-turn or basic gyroscope) means you must clear the floor entirely before running the vacuum.
- LIDAR can support room mapping and systematic navigation, including low-light operation on some models.
Final checks before comparing picks
- Recheck the exact sensor package and navigation technology.
- Determine how much you are willing to tidy up before a cleaning run.
- Review the required maintenance routine, such as cleaning sensors and cameras.
