Long chose between this model, and the same, but the previous generation. The difference is not significant. This one is better oriented in space, while the last one has a bunch of voice packages for every taste and color. Compared to the third generation - there is no wet cleaning (rags attached to the work). As for me: it is better to wipe it with detergent. By features. The robot does not like it when children put the steps. Then he goes around this place and does not vacuum. And if you close the door to the room when he is driving, and then open it, then he will not go to the room during this cleaning session (but you can send him there separately later). I didn’t notice any problems with wool, the bottom brush is easily removed and cleaned. If the container is still dusty after shaking out the garbage, compressed air will help.
