Floor mats are used in vehicles to protect the interior from dirt, water, salt and snow. There are different types of floor mats designed for various weather conditions, including carpet, rubber, vinyl and all-weather mats. Carpet mats are most common but require more cleaning, while rubber mats are best for wet climates as they prevent water and slush from getting inside. Vinyl mats fit vehicle interiors like rubber mats but are see-through, and all-weather mats contain ridges to trap dirt and are suitable for daily use in any weather condition.
