1. A method for cleaning a workspace, comprising:
autonomously moving, with a mechanism of a robot, at least a cloth of a mopping assembly of the robot upwards and downwards relative to a work surface of the work space, wherein:
the robot comprises:
a fluid reservoir for storing a cleaning fluid; and
the mopping assembly comprises the cloth for mopping the work surface, the cloth being oriented toward the work surface;
the cloth is disengaged from the work surface when the at least the cloth is moved upwards relative to the work surface such that the cloth is not in contact with the work surface;
the cloth is engaged with the work surface when the at least the cloth is moved downwards relative to the work surface such that the cloth is in contact with the work surface;
the mechanism moves the at least the cloth of the mopping assembly upwards and downwards relative to the work surface based on input provided by at least one sensor of the robot;
the robot comprises at least one nozzle for delivery of the cleaning fluid; and
the mechanism comprises a motor for moving the at least the cloth of the mopping assembly upwards and downwards; and
the robot comprises mopping functionality and vacuuming functionality for mopping and vacuuming the work surface during a same cleaning session.
