On demand electromechanical dispenser of cleaning solution

A dispenser comprising a cover housing, main housing, and base housing is provided. The cover housing includes an upper housing including a dispensing mechanism for dispensing cleaning solution from a holding reservoir. The main housing includes a cleaning solution storage reservoir, and a positive-displacement mechanism for electromechanically transporting cleaning solution from the storage reservoir to the holding reservoir. The base housing includes a ratcheting mechanism for causing the positive-displacement mechanism to rotate, and a power-spring mechanism for generating resistance against the ratcheting mechanism. The dispenser further includes a microprocessor configured to receive a signal indicating a sensing system has identified a dispense trigger, relay a signal to a pump motor to operate accordingly, determine that the holding reservoir is to be refilled, and actuate the positive-displacement mechanism to refill the holding reservoir. The dispenser further includes an electrical power system for supplying electrical power to electrical components of the dispenser.
