Abstract: Systems and methods for model evaluation using prior data are disclosed. A system can store a set of inputs provided to a first model to generate first data points for a first live event. Each input of the set of inputs can include a respective state of the first live event. The system can initiate an execution environment for a second model configured to generate second data points for the first live event. The system can execute the second model within the execution environment using the set of inputs to generate candidate data points for the first live event. The system can generate a score based on the first data points, the candidate data points, and one or more corresponding outcomes of the first live event. The system can set a flag to replace the first model with the second model responsive to the score satisfying a threshold.

Abstract: A steam cleaning apparatus may include a wand, a cleaning assembly coupled to the wand, the cleaning assembly including a steam generator, and a cleaning head pivotally coupled to the wand. The cleaning head may include a plurality of cleaning pads, a pad motor having a motor driveshaft, a drivetrain configured to transfer rotational motion of the motor driveshaft to each of the plurality of cleaning pads such that a rotation of the motor driveshaft causes a corresponding rotation in each of the plurality of cleaning pads, and a temperature sensor positioned proximate to the drivetrain, the temperature sensor being configured to measure a temperature of the drivetrain.
