Abstract
A system may monitor usage of a cleaning chemical and indicate when the chemical has expired and needs to be replaced. In some examples, the system includes a reservoir containing the chemical and a sensor associated with the reservoir that can detect user interaction with the chemical in the reservoir. The system may track an amount of time until the chemical in the reservoir is deemed to have expired and provide a user alert indicating expiration of the chemical. The system can control the amount of time remaining until the chemical is deemed to have expired based on the detected addition of the object to the reservoir.
