Different pros: We use three weeks. Removes the rules. There is a dog in the house, finally you can not bathe about wool. In general, I like it very much, especially for a child (teenager) - saving time on cleaning - no more bickering about cleanliness in the room. The vacuum cleaner disciplines the household not to leave too much in its path)))) Different cons: Expected for a round log - the corners need to be cleaned additionally. It happens that it gets stuck on the threshold to the bathroom, although the threshold is not high.
