The time of watering and the timing of spraying or watering the detergent are controlled. These operations are performed by the operation panel 1 installed outside the bathroom.
The automatic operation is performed by operating the operation switch 7.

[0005]

The use of the bathroom cleaning apparatus constructed as described above is at most once a day, and there is a long pause between the next operation and the operation. In the final stage, ventilation for bathroom drying is performed for a relatively long time. A problem under such use conditions is that the detergent remaining near the outlet of the nozzle hole for spraying the detergent is dried and solidified to cause clogging of the nozzle hole. Detergent sprayed from the cleaning device configured as described above is sprayed from each detergent nozzle after being diluted with water to an appropriate concentration, but the detergent liquid remains outside the nozzle hole exposed to the outside air. It is unavoidable that clogging is likely to occur when there is.

[0006] Further, when installed on a wall surface as described above, the spray or dripping of the detergent sprayed from the detergent nozzle adheres to the case surface of the cleaning device, and adheres to the case surface when left as it is. The stain-like stain will be fixed.
