  • Patent number: 6463940
    Abstract: A method and system provide an automated cleaning apparatus for cleaning various types of articles, wherein each type of article is detected and washed according to its own pre-determined combination. The cleaning apparatus has a storage device storing an array of pre-determined chemical combinations and cleaning parameters, including specifying cleaning chemicals to be used on the various identified article types. A transponder is provided with identifying information of the article type. A transceiver detects the type of article from the transponder and communicates that identifying information to a processor. Based on the detected identifier, the processor selects from the storage device the proper chemical combination and cleaning parameters for washing the identified type of article. A control device coupled to the processor delivers the chemicals specified by the selected chemical combination.
