Rug shows dirt easily and does not clean

I only buy wool rugs because they repel dirt and typically stay clean. Even if wine or mud get on them, they can be spot cleaned easily with carpet cleaner. I purchased this rug because I thought it was wool. Otherwise, i never would have purchased it because it has so much white on it and i am using it in a high traffic area of my home; at the front door, and also under the coffee table in our living room. Turns out, this rug is a wool blend, containing only 1% wool. This rug started to show dirt almost immediately and the dirt does not come out with any kind of carpet cleaner. I am extremely disappointed and feel that i was misled by Overstock. I searched for "wool" rugs when searching and finding this rug, and did not expect to get a "wool blend". I just bought replacement rugs and i made sure they were 100% wool. From now on, i will remember to read the fine print!
