After one pass, I was surprised how much he has collected together. His thoroughness I recognize also the fact that when we have breakfast when carrying out daily bread crumbs RELIABLE, and I really need to stress once more every day all gone. I sometimes have the impression that this "Along the wall drive mode" bit too much, but the cleanliness gives him just right. Now you only have to clean once a week and the floor is spotless! In contrast to our previous model 620, the robot has no brush rollers but what is the point for me ne plus ultra. The rollers collect only on stock hair on (once a week to clean is sufficient, and this is compared to the old super fast and easy). I can tell from our brief experience, sufficient care once a week, and the care takes more than 5 minutes + every other times empty the dust container until the third day.
The robot is quieter than the old model and thorough. For 629 you get in the media market the Roomba 880, which even a Room to Room mode has, what I really need, however, not because my 85sqm apartment to be cleaned without any problems.
I am very happy with my robot and can only recommend for this model and not to opt for the previous models, the advantage with the cleaning rollers instead of brushes is an innovation that will make the robot now really a great help!
** Only disadvantage I could find so far: our couch is too shallow the Roobi can go under it, now he always goes against it. Since the robot after a few days even getting a bit dusty on our couch is the lower two centimeters Anyway the dust by the robot, which is also on all other models, however, is the case.
