I order everything on Amazon, alas, I have not often time to note the vendors (all of which are 5/5!) Or speak of a purchased product. This robot, purchased in July, deserves attention. At first, as shown in the leaflet, must be able to scan and "remember" the place: just follow the instructions, in a word, keep it, simply. Now, my robot knows every corner of our home and works more than perfectly. I admit that it is a luxury that I did not dare buy but my life is thereby actually facilitated. Bravo and thank you.
