Question about iRobot Roomba i7

Hello.
So: it can also be started remotely (not at home) via app as long as the hoover has wifi connection (position the docking station accordingly).
You can define which rooms you want to clean and which should be ignored, but only after a few "whole house cleanings" because the hoover first has to create a map of the flat. You then have to "separate" and name the rooms on the digital map yourself before you can use this function.
It comes with a "lighthouse" with which you can create an invisible barrier that the robot cannot pass. Only 1 is included, but you can buy as many as you like.
This hoover model cannot recognise objects on the floor and therefore approaches unexpected obstacles. If they are light enough, they are simply pulled along or moved, if they are heavier things, then it recognises them as a "wall" and starts to find a diversion all around. Cables are either pulled along, run over (then danger of trapping!) or if they are under tension they can trigger the trigger and are recognised as a fixed obstacle.
For a robot with active obstacle detection, you have to go for a more expensive model with laser navigation or laser scanner. This costs a lot more, but it recognises objects lying around, can distinguish them from fixed obstacles such as sofas or walls and automatically steers around them without touching them. This is a particularly important function when the house is not always perfectly tidy. With the model you asked about, the floor must always be tidy and obstacles must be removed before vacuuming (including slippers, laundry, toys, cables, etc.). Otherwise it will be difficult... As I said, you can exclude rooms from the cleaning process if you know that there are objects lying around (or exclude something using the Virtual Wall).
Last but not least: you can't see in the app where the hoover is currently moving, only whether it is in motion or whether it has a problem or is charging.
With modern devices with laser navigation, you can usually see live on the map where the robot is and with some models you can even watch the journey live through the built-in camera.
