The instrument deposited by Amazon product description is also incorrect and evidently refers to another model! There 're no camera on the top!
Once that is resolved with Amazon, my review will be revised. The device receives the time being therefore only one star.
EDIT 01/30/2015:
Amazon.com has just withdrawn the device due to my complaint and I was offered a replacement, but I refused. The researchers assumed that a replacement would be an Italian again ;-)
Amazon.com has confirmed that the problem was passed "the person responsible".
In my short test operation I could see that my navigation has not convinced. The camera above but would obviously be necessary to achieve detection of the room, thus enabling a systematic cleaning. I've noticed that yet again all the sections were not approached in the room.
