What is a characteristic of Type 1 clothes dryers?

Type 1 clothes dryers are primarily designed for residential use, making them more suitable for family living environments. These dryers are typically characterized by their size, energy efficiency, and user-friendly features that cater to the needs of households.

In contrast, clothes dryers used in commercial settings (like laundromats) often fall under different classifications and are built for high-capacity use with additional features, which is not characteristic of Type 1 dryers. They also do not have to be coin-operated; that feature is more common in commercial machines to facilitate inclusive laundry services. The notion of operation exclusively by an attendant is also misaligned with the Type 1 classification, as these dryers are intended for direct consumer use without the need for an attendant's assistance.
