Carpet tiles, also known as carpet squares, are currently the most popular form of commercial carpeting. One of the biggest appeals of carpet tiles is that when one (or a set of them in the same area) wear out, all you have to do is replace the ones that are worn.
One problem with carpet tiles is if they are not resistant to water. This means that if the backing gets moisture behind it, the tile can be ruined. There is no drying like you can with a broadloom. Low moisture cleaning methods are great for carpet tiles for this very reason.
As with all carpets, regular vacuuming is essential for the longevity of the carpet. As for measures against stains, putting baking soda on the stain before it dries, then vacuuming it up often works.
