Abstract
Examples provide a smart maintenance cart for cleaning temperature-controlled display cases. The maintenance cart includes a main body including a set of water tanks, a pump, a vacuum, a set of hoses, a drain hose filter, a set of rollers, a memory, and a processor. A smart maintenance controller analyzes the sensor data using a set of per-case, customized performance thresholds. The smart maintenance controller generates a set of priority rankings for a set of temperature-controlled display cases based on a result of the analysis of the sensor data. The smart maintenance controller identifies a highest priority case in the set of temperature-controlled display cases for maintenance based on the set of priority rankings. The smart maintenance controller outputs a maintenance task notification to a user, the maintenance task notification comprising a case identifier associated with the highest priority case for cleaning.
