After a cleaning device is powered-on and initialized, a water path self-detection method for the cleaning device comprises the following steps: 1) judging whether a low water level switch is turned on; if so, controlling a water inlet valve to be turned on, controlling a water pump to be turned off, and going to step 2; if not, controlling the water pump to be turned on, controlling the water inlet valve to be turned off, and going to step 3; 2) judging whether a water replenishment time exceeds a preset first threshold; if so, a fault is confirmed, and the water inlet valve is controlled to be turned off; and if not, returning to step 1; 3) judging whether the low water level switch is turned on; and 4) judging whether a water pumping time exceeds a preset second threshold.
