Can I just cover the cables under the sofa with tape, will that work when the Roomba runs over it without any problems?

If the cables are taut or in a cable channel, the iRobot goes over them - just make sure that the cable is not wrapped up in the rotating brush - but it works quite well ... I am very satisfied with the iRobot 960!

Now I see that the Roomba has space under the upholstery because of its height, I also have a lot of cables there, what is the best solution? I don't think the wall is enough
