Have the unit now almost a month and am very satisfied. Roomba is very satisfactory from the volume here, it can also be turned on when my children are asleep and they will not be monitored. I was very excited because I did not think he really does so grüdlich clean. It also comes easily under our cabinets and living room furniture. Also designed carpets unless they are severe enough that he does not push together, are not a problem and will thoroughly clean even hair are well removed from the carpet. The cleaning of the brushes is very easy thanks to the included accessories. However, man must not hurry it, because if a space is not only quadrangular but perhaps as an L odre is somehow different cut, the extended working time significantly. However, he has only a short loading times and is quickly ready for use again. This works with the lighthouse also good, so you do not always close all doors, or you can define some space. Criticisms: At low thresholds (for example, change tile floor) runs Roomba often times along the longitudinal axis and then caught by the difference in level not all the dirt. If you have quite a large deep tile joints, the wheels rattle a bit noisy.
