The invention discloses a cleaning device suitable for a student dormitory. The cleaning device comprises a sweeping robot and a water absorption device which is installed at one side of the sweeping robot. In order to enable the water absorption device to work more intelligently, ponding detection devices and fixators are installed around the water absorption device. During the period of sweeping, when ponding water is detected, the water absorption device is started to perform ponding water removing operation. Now, student dormitories mostly use thermos flasks to store hot water or use water dispensers to get water, lots of ponding water accumulates on the ground because of quality problems of a device, and the cleaning device suitable for the student dormitory has the quite obvious effect on solving the problem of ground ponding.
