System and method to clean a range exhaust

A system, comprising:

• a nozzle coupled to a conduit and arranged to spray a zone of a cooking range exhaust system;
• a pump configured to provide a cleaning solution to a supply line;
• and
• a control box connected to the pump and comprising a controller and an electronically-controlled valve configured to selectively couple the supply line to the conduit, wherein the controller is configured to, in response to receipt of a start signal to initiate a cleaning operation:
• cause a reservoir to fill with a mixture of detergent and water having a ratio based on a target mixing ratio to form the cleaning solution, wherein causing the reservoir to fill with the mixture of detergent and water includes monitoring a float switch mechanism at least partially in the reservoir to determine the reservoir contains a minimum threshold of the water prior to causing the detergent to be added to the reservoir;
• cause the cleaning solution to be provided to the supply line;
• and
• cause the electronically-controlled valve to open to facilitate provision of the cleaning solution to the nozzle via the conduit for a predetermined period of time.
