I use regularly (at least 2 times a week) the neato XV-25 for 2 and a half months: large living room, nice kitchen, hall, three bedrooms and two bathrooms. It is a remarkable power unit and very, very clever: when the battery is empty, he returned to his office and once it is completed, he returned to where it left off and finished the work he had planned in the beginning. without any intervention. He aspires remarkably carpets, even thicker. I have a British Longhair cat, and I know what I mean! Small note about the review previous 4 star when starting and thus the programming of the room are made, do not change over the layout of the room because it is unable to redo a second programming during operation. I regret not qu'Amazone.fr offers accessories dust filters, battery, magnetized roller that will eventually need to be replaced or purchased as a supplement. I keep them 5 stars, the robot is not responsible for these shortcomings.
