Does this model have any kind of internet connection / uplink? Is any data transmitted anywhere?

Where can I find spare parts for the irobot 866 ?

1. he keeps getting wedged under the toilet bowl...do you have a tip? 2. does the romba have trouble in the dark? sometimes it just stays like that and when i come home i have to look for it first - usually in the dark bedroom, under the sofa...or just under the toilet bowl...

Does this Roomba move from room to room? Or does it have to be moved manually to other rooms.

What is error 9? It stops after 3 minutes, after running almost in circles, then error 9 occurs.

How long is the normal warranty without the 5-year extension for 51 francs? Do you only have a 30-day right of return if you don't take it out? With such a not cheap device...

Can this model overcome door thresholds of approx. 3 cm in height? If not, is there a robot hoover that can do this?
