Frequently Asked Questions
What does LiDAR stand for in robot vacuums?
LiDAR stands for Light Detection And Ranging. It uses laser pulses to measure distances and build a map of your home.
How does LiDAR navigation compare to camera-based navigation?
LiDAR works perfectly in total darkness and is generally more accurate, but it often costs more. Camera systems struggle in the dark or in plain rooms with all white walls.
Does a robot vacuum with LiDAR clean in straight lines?
Yes, LiDAR creates a stable, accurate map that lets the vacuum clean in neat, straight lines instead of bouncing around randomly, covering every corner faster.
Do I need a vacuum with LiDAR?
If you have a small, open apartment with few obstacles, you can get by without LiDAR. But for larger homes with many obstacles, LiDAR helps avoid getting stuck and cleans more efficiently.
The bottom line
LiDAR is the gold standard for robot vacuum navigation because it’s fast, accurate, and works in the dark. If your budget allows and you want a vacuum that truly “knows” your home, look for one with a little laser tower on top. For tiny apartments or tight budgets, camera or random‑bump models can still do the job — just expect a bit more random wandering and a longer cleaning time.
