And it does not protrude to the front side of the vehicle body 2 to increase its overall length.
For this reason, even if the travel path is narrow and low, it can be easily traveled and the cleaning operation can be performed without any trouble.
Since the operator can remotely operate the bottom washing vehicle 1 by using the wireless control device 40, the operator does not have to enter the work site directly, and can work safely.

In addition, although the traveling body 3 was a crawler in the previous example, it is not restricted to this, For example, the tire of four wheels or more may be sufficient.
In the previous example, the lifting cylinder 7 is a pair of left and right, but is not limited thereto, and may be a single one, for example.
In the previous example, the cleaning device 8 can be swung around the front-rear axis, but is not limited thereto, and may be swung around the front-rear axis and the left-right axis, for example.
In the previous example, the cleaning device 8 has the injection means 23 smaller than the vehicle width of the ship bottom cleaning vehicle 1, but is not limited thereto, and may be substantially the same as the vehicle width of the boat bottom cleaning vehicle 1, for example. In this way, the cleaning operation can be performed over a range substantially equivalent to the vehicle width by a single run, and the efficiency of the cleaning operation can be improved.
In the previous example, the discharge pipe 26 is directed to the side in the previous example. In this way, there is no possibility that the suction hose 38 connected to the discharge pipe 26 will be damaged by coming into contact with the board or the like.
