On demand electromechanical dispenser of cleaning solution

A method for automatically dispensing a cleaning solution, the method comprising:

• providing an on-demand electromechanical dispenser of cleaning solution, the dispenser comprising:
• a cover housing comprising:
• an upper housing comprising:
• a dispensing mechanism configured to electromechanically dispense cleaning solution from a holding reservoir;
• a main housing comprising:
• a cleaning solution storage reservoir, and
• a positive-displacement mechanism configured to electromechanically transport cleaning solution from the storage reservoir to the holding reservoir;
• a base housing comprising:
• a ratcheting mechanism configured to allow the positive-displacement mechanism to rotate in a single rotational direction, and
• a power-spring mechanism configured to generate resistance against the ratcheting mechanism;
• and
• a microprocessor,
• receiving, by the microprocessor, a signal indicating identification of a dispense trigger,
• causing, by the microprocessor, activation of a pump motor to dispense cleaning solution from the holding reservoir, and
• causing, by the microprocessor, activation of the positive-displacement mechanism to refill the holding reservoir with contents of the storage reservoir.
