4 Reasons LiDAR Beats vSLAM for Robot Vacuums

Works in total darkness LiDAR uses lasers to map a room, so it navigates perfectly with the lights off. vSLAM cameras struggle in low light and may bump into objects.

Maps faster LiDAR scans a room more quickly than a camera-based system. The [Roborock Q](https://www.amazon.com/s?k=Roborock+Q&tag=wehavethat-20)revo finishes mapping before the Roomba S9+ has even figured out the layout.

Fewer collisions LiDAR detects obstacles from all angles without needing light. vSLAM tends to take tentative paths and bumps into things more often in dim conditions.

Better for nighttime cleaning If you run your vacuum while asleep or away, LiDAR is the clear choice. It does not need to see to know where it is going.
