How do robot vacuums map rooms and avoid obstacles?

04 Eyl 04:00

I'm new to robot vacuums and fascinated by how they actually figure out the layout of my flat. Do most of them rely on SLAM with LiDAR, visual odometry, or just simple bump sensors? How do they decide the cleaning path and handle dynamic obstacles like pets or shoes? Also, what's the usual approach for mapping multiple floors? I'd love to hear explanations or resources you recommend, and any tips on getting the most accurate maps without buying a high‑end model. 🤖🧹
