The system is very simple. We put the band on the ground and the Neato take to a wall. This is useful to limit laccès to certain places. Personally, I used me to prevent access to my long-pile carpet (where my only obstacle XV-14 crash) and the feet of our rocking chair (the robot climbs and lose time for nothing ). That said, be aware that the Neato will slightly go over the tape to detect. Sometimes it is taken into account. Furthermore, the magnetic power is correct but will hardly be detected if you put it under something too thick. Finally, take care to put your side by side strips if you form angles; For wanting to cheat a little to make the distance, I left a small centimeter of space between two bands at the corner of my carpet. This in enough for the robot spends its sensor and a wheel. What gave me a crazy robot detects an insurmountable wall between its two wheels. A last details to finish: the robot sometimes moving the web (himself or simply pushing something on it). To be safe, so it's best to fix it with 2 or 3 pieces of double-sided.
