Robot vacuums now rely on a hybrid SLAM stack that fuses lidar point clouds, RGB‑D camera frames, and short‑range IR or ultrasonic rangefinders. The raw lidar data gives a high‑precision 2‑D floor plan, while the camera adds texture cues for obstacle classification (e.g., pet fur vs a chair leg). All sensors feed a lightweight EKF‑based SLAM algorithm running on the device’s MCU/GPU, so the map is built and updated locally in real time. Only the trimmed map file and usage statistics are uploaded to the cloud for firmware‑guided improvements or multi‑device sync; the heavy‑lifting path‑planning stays on‑board to keep latency low and protect privacy.
Compared to a typical Roomba, which leans heavily on a single downward‑facing optical flow sensor and bumpers, a Roborock‑style unit with lidar and a fisheye camera can detect dynamic obstacles and re‑route instantly, which becomes obvious on carpet‑hard floor transitions. The firmware detects a sudden change in surface reflectivity and adjusts suction power and wheel torque on the fly, something a pure optical‑flow system struggles with. Looking ahead, integrating a solid‑state 3‑D time‑of‑flight sensor or even a tiny radar array would give depth perception through dust and low‑light conditions, while edge‑AI chips could run deep‑learning‑based object recognition on‑device, cutting down the need for cloud inference and further sharpening navigation on multi‑level homes.
