The Short Answer
Soft serve ice cream needs to be constantly stirred to keep it from hardening in the machine and to flow out when released, which means that the machine is constantly running for something like 18 hours a day. Because it needs to stir an enclosed canister of pressurized sugary milk, there need to be seals where the shaft of the motor transitions through. These seals require food-safe lubrication, as well as detailed cleaning of the mechanisms on a regular basis to prevent the dairy products from spoiling (dairy is a high risk food item, and spoils easily). This means a complex piece of equipment which is subject to long periods of high wear operation must be regularly broken down, cleaned, lubricated, and reassembled by the type of people who work at a fast food restaurant. Frankly it is a miracle that it works at all.
