This is the third day I use the new Neato and I love it more and more! The first day he cleaned the bottom of the house 3x, 2x 2nd day and today one once. So improving day by day! It is noisy but this noise is more tolerable than the Roomba. Cleaning is also much higher than the Roomba. Small flat, it does not recognize the emptiness of the stairs unlike Roomba (it takes place the black strip in front of the stairs to prevent falls) The tray is also quite small. He refuses to get on the carpet has long hair but passes without any worries on Rug doormats. Its navigation system is sometimes strange but he forgets any area and this is the main. Very happy with my purchase: 0)) Note that the original carton had already been opened and that no protective film on the base (already used ??) Delivery of consistent amazon. to what had been announced (as always with amazon)
