1. A formulation delivery system, comprising:
a reusable handle configured to reversibly receive a formulation cartridge configured to store a formulation therein and a cleaning cartridge configured to store a cleaning liquid therein;
a formulation dispensing assembly including a reciprocating nozzle assembly and a pump, the reciprocating nozzle assembly fluidically coupleable, via one or more fluid conduits, to the formulation cartridge, or the cleaning cartridge, received within the reusable handle; and
a controller including computational circuitry and logic configured to toggle between at least a cleaning routine and formulation routine responsive to one or more inputs indicative of the cleaning cartridge or the formulation cartridge inserted into the reusable handle, wherein the controller is further configured to operate the pump at a higher flow rate in the cleaning routine as compared to flow rate in the formulation routine.
