Not the person you’ve replied to, but I’ve got a Roborock Q7 Max. It’s cheap and relatively simple. It’s got a LIDAR and proximity sensors, but no obstacle avoidance or stair/cliff detection and no camera. From what I can see it’s also silent (no network activity) even though it’s bound to my WiFi. After months of using it I’d say its been a great choice to splurge on. Never had one, never thought I’d need one, but after seeing dust settling on every bit of the floor every day… I got tired of sweeping.
