What type of tanks should be mounted on the exterior of a carpet cleaning vehicle?

For a carpet cleaning vehicle, propane tanks are specifically utilized to fuel the heating systems that enable hot water extraction methods during the cleaning process. These tanks are crucial for generating heat, which enhances the efficiency of stain removal on carpets. When heated, water can more effectively dissolve and lift dirt, grease, and other stains, leading to a deeper clean.

In the context of carpet cleaning, other tank types, such as water tanks, would typically be kept inside the vehicle for safety and efficiency during operation. Fuel tanks are essential for powering the vehicle itself but are not directly related to the carpet cleaning process in the way propane tanks are. Chemical tanks may be used for the solutions applied during cleaning; however, they do not play the same role as propane in providing heat. Therefore, using propane tanks mounted externally is both a practical and necessary configuration for efficient carpet cleaning operations.
