Please let us know if your flat has inside thresholds (a steel threshold around 3 mm high), as these will prevent the floor polisher from entering your home. The official website says nothing about this; the only notable feature is that it has efficient navigation that allows you to go around carpets. This is, of course, a marketing gimmick; the robot avoids carpets not because of navigation but because of a design feature that prevents it from driving into any such low obstacles.
