I have never owned an iRobot, but my friend does. He sees mine has color maps, LEDs that automatically turn on when it’s in a dark area, has a camera+lidar, which you can use the camera to watch, and has two way audio. If you also search the Roborock forum here for people migrating from iRobot to Roborock, you’ll find similar complaints regarding iRobot, and how they wish they just got Roborock sooner, etc.
If you’re trying to record someone, that’s actually highly illegal in some places .Just sayin
