For homeowner’s who either vacuum their carpets regularly or have them vacuumed regularly, wool will last longer than other fibers and would be a good investment. The reason that vacuuming is so important is that through normal home living, grit gets into the carpet fibers. If this grit is not removed by regular vacuuming, it will act like sand paper on the carpet fibers, damage them and create premature wear patterns. Therefore, if regular vacuuming of your carpets may be difficult to achieve, it might be prudent to invest in a less expensive type of carpet.
If spills and staining are not a big concern, wool once again is an excellent choice. Wool has natural oils inherent in it which have a tendency to repel liquids. Therefore, if you can get to spills quickly, the wool provides good stain resistant qualities. However, if a spill is left unattended, it seeps past the natural oils in the wool, absorbs into the fibers and has a high probability of becoming a permanent stain. Therefore, if your main concern is staining (from kids, pets, etc.), then synthetic carpets would most likely serve you best. They come in all "levels" of stain-resistance, from very basic synthetic fibers, to those treated with Teflon and other solutions.
So, if you have good maintenance of your carpets and have the ability to address spills quickly, then wool, over its life, is your most cost effective choice. However, it either of the above concerns is an issue, then your money might be better spent on a synthetic carpet.
