Although they are long-lasting, area rugs need to be changed once in a while. It doesn't matter how often you clean it or take care of it; when an area rug has seen its glory days, it will start exhibiting signs that show that it needs to be replaced. Some of the signs include the obvious wear and tear that shows you how irreparable it has become. There's also a persistently weird smell that'll ooze from it. Generally, if your rug is synthetic, you'll need to replace it after 10 years. Natural rugs can last up to 3-5 years, maybe more, depending on how you use them.
