Unlike this type of conventional example, it can be reused many times without being discarded, thus eliminating waste.

Seventh, when the cleaning of the chamber 6 with the cleaning liquid S is completed, the three-way valves 18 provided on the supply pipe 13 and the collection pipe 14 are switched. Then, instead of the cleaning liquid S from the liquid tank 11, the water from the water tank 15 is supplied from the supply pipe 13 to the sprinkler portion 12, and is jetted and sprayed into the room 6, so that the upper surface 1 of the room 6 and each side surface. 4. The cleaning liquid S that has been sprayed and adhered and remains on the floor surface 3 is washed away. The water thus washed away with the cleaning liquid S is recovered from the opening 5 into the waste liquid tank 16 via the recovery pipe 14 and the three-way valve 18. In this way, the chamber 6 of the container B such as a tank or a container is thoroughly washed out after washing, but such washing and replacement of the washing liquid S can be easily and easily performed by switching the three-way valve 18. . In the prior art example of FIG. 2 described above, it was pointed out that the liquid receiver 9 had to be replaced each time, which made it troublesome to wash it off after the fact.
