Problem to be solved: to provide an operator with an operator who performs a handwashing with reduced dispersion which excludes an individual difference.A cleaning monitoring method for monitoring the execution of the cleaning treatment of the cleaning object is to detect the presence or absence of a washing object in the cleaning position, and to start the cleaning processing when detecting the presence of the cleaning object in the cleaning position, and the absence of the cleaning object before the cleaning processing is completed When detected, the execution of the cleaning processing is interrupted to generate a signal indicative of the incomplete completion of the cleaning process.Selectable diagram 3C【課題】作業者に対し個人差を排除したばらつきを少なくした手洗いを行わせる装置を提供する。【解決手段】洗浄対象の洗浄処理の実行を監視する洗浄監視方法は、洗浄位置における洗浄対象の存在の有無を検出するステップと、洗浄位置に洗浄対象の存在を検出したときに、洗浄処理を開始するステップと、洗浄処理が完了する前に、洗浄対象の不在を検出したときに、洗浄処理の実行を中断して、洗浄処理の未完了を表す信号を生成するステップを含む。【選択図】図3C
