To provide a cleaning device which appropriately supplies a detergent to a washing cloth.
A detergent supplying mechanism 30 has: a detergent tank 32; a detergent take-out line 33 for taking out the detergent 31 from the detergent tank 32; a channel switching mechanism 34 including an inlet portion 34a, a discharge side outlet portion 34b and a tank side outlet portion 34c; a detergent discharge line 35; a detergent return line 36; and a channel control section 37 which controls the channel switching mechanism 34. The channel control section 37 controls the channel switching mechanism 34 so that the inlet portion 34a of the channel switching mechanism 34 is connected with the discharge side outlet portion 34b at the time of cleaning, and consequently so that the detergent 31 is supplied to a discharge head 16 through the detergent discharge line 35. The channel control section 37 also controls the channel switching mechanism 34 so that the inlet portion 34a of the channel switching mechanism 34 is connected with the tank side outlet portion 34c at the time of rest of cleaning, and consequently so that the detergent 31 is returned to the detergent tank 32 through the detergent return line 36.
