Perhaps Roomba's class in huge rooms. In my old apartment but there are a lot of corners, angles, edges. For this purpose, for example, chairs, a table, a TV table with casters, a desk, a computer, many standing bookshelves .... I suck dust itself, then I lift the chairs briefly, put them down again, the role of TV table shortly before etc . & c., all the way in passing during vacuuming. For Roomba, however, I must prepare everything first - best all the chairs out or highly (afterwards back again). I have to work your Roomba So - - - what I'm otherwise very quickly while vacuuming the way, is now an extra - operation - and afterwards a second, because it has everything in his place back. In between Roomba eats repeatedly firmly - to ordinary table legs, numerous angles (eg between bookshelf and wall or just anywhere else in the old building). Then, the hammer: he just can not get into the many corners, for he is around. Since the small brush benefits not really, this is simply untrue. The many corners of the room, but also every little corner between the furniture and the respective wall there everything, fluffy accumulates like Roomba and da does not come back, unfortunately. That is, if the Roomba is even finished sometime, then located in the corners still dust and then I'll come and suck or sweep all large and small corners to. At least here it is so absurd. I look at all this together, only time spent on preparation and follow, so I have much faster with the normal vacuum cleaner sucked finished. I count how many times I have to rush to the aid of the Roomba, but because he is stuck back in a corner or under semi Vertiko, I need more time with him. Before furniture he considers either a much too large a respectful distance or he dotzt very violent and unrestrained in the furniture or he tries under pieces of furniture that are actually too low for him, back with a vengeance and almost Power and again drunterzuquetschen - a total he bangs so, however, that I'm sorry about my few fine, expensive antiques. I watch him as he vorbeizockelt to a fluff again and again, they finally caught up with his small propeller-side broom randomly, but instead they suck, it blows --- namely there in the area where it is not guaranteed to go back there must because he was already 10 times, then the action is completely for comedy. Roomba may be great for large rooms or halls with little furniture, where it can make long walks. It is also a fun toy. As a home appliance impractical. I hope to Roomba's great-great grandson in later years ...
