1. An autonomous wet floor cleaner for wet cleaning an environment, the autonomous wet floor cleaner comprising:
a navigation system for autonomously localizing and navigating the autonomous wet floor cleaner about an environment;
a drive system for autonomously driving the autonomous wet floor cleaner according to the navigation system;
a cleaning fluid dispenser system including a supply tank for cleaning fluid, wherein the cleaning fluid dispenser system is configured to dispense cleaning fluid from the supply tank along a cleaning fluid flow path;
a recovery system including a recovery tank for recovering dirty fluid and a suction source in fluid communication with the recovery tank, wherein the suction source is configured to recover dirty fluid into the recovery tank;
a controller configured to control the autonomous wet floor cleaner according to a plurality of autonomous wet floor cleaner instructions stored in memory, wherein the controller is configured to identify a cleaning fluid pooling precursor event by analyzing one or more of the plurality of autonomous wet floor cleaner instructions to predict pooling of cleaning fluid and in response control one or more of the drive system, cleaning fluid dispenser system, and the recovery system to mitigate fluid pooling associated with the identified autonomous wet floor cleaner instruction.
