A device for cleaning channels of an endoscope has its main body in which a first check valve for permitting merely suction of a liquid detergent into said main body, a syringe for effecting suction and discharge of the liquid detergent and a second check valve for permitting only discharge of the liquid detergent from said main body are provided so that the channels can be cleaned by feeding the liquid detergent thereinto through liquid feed tubes. Further including a transfer valve, a pluraltiy of channels can be selectively and switchably cleaned. In addition, a filter apparatus is provided in the device so as to be able to prevent foreign matters contained in the liquid detergent from entering the channels of the endoscope.
