Bought for clean hardwood floor. It is good enough and surpassed my expectation, just keep in mind: it is not human-being, does not expect its inteligence of a human, it is already smart enough to swipe around the house ,no complain at all. Some people complains about the qualuty, but image this small machine did a heavy work, if runs for year, only cost $10/per month, do not be too greedy. And it is not used to clean large objects, clean unnoticable dust and dirty is its goal. Why expect a cat could catch a wolf, that does not make sense, right place, right usage, this is the key point.Get more detail about iRobot Roomba Silver.
