PROBLEM TO BE SOLVED: To swiftly feed cells with a bubble-free cleansing liquid while preventing a bubble-containing cleansing liquid from being fed. SOLUTION: A cell-cleansing system 1 is provided, including: a cell container 2; a feed pipe 7 to feed a cleansing liquid into the container 2; a pump 8 to feed the cleansing liquid in the feed pipe 7 toward the container 2; a reservoir 10, that is set midway of the feed pipe 7, so as to extend above the feed pipe 7 and composed of a recessed part for catching bubbles in the cleansing liquid; a sensor 9 installed in the feed pipe 7 between the pump 8 and the reservoir 10 and functioning to detect bubbles flowing in the feed pipe 7; and a controller 11 to make a control so as to reduce the speed of the cleansing liquid flow by the pump 8 when bubbles are detected by the sensor 9.
