LiDAR vs vSLAM: LiDAR wins for night runs and speed

LiDAR laser mapping works perfectly in pitch black, while vSLAM cameras struggle in low light and take more tentative paths. The Roborock Qrevo maps faster and bumps into fewer things than the Roomba S9+. If your vacuum runs while you’re asleep or away, LiDAR is the clear winner — it doesn’t need to see to know where it’s going.
