A device capable of adhering to a wall surface by suction by the pressure of an ambient fluid and treating the wall surface, which comprises a pressure receiver member and a partition defining a pressure reduction zone in cooperation with the pressure receiver member and the wall surface. In one aspect, the partition has a sealing function of preventing inflow of a large amount of an outside fluid into the pressure reduction zone, and a treating function of treating the wall surface by being moved in a required manner. In another aspect, the partition has the above sealing function, and a travelling function of moving the device, by being rotated about an axis of rotation slightly inclined to an axis which is substantially perpendicular to the wall surface.

Abstract

A device capable of adhering to a wall surface by suction by the pressure of an ambient fluid and treating the wall surface, which comprises a pressure receiver member and a partition defining a pressure reduction zone in cooperation with the pressure receiver member and the wall surface. In one aspect, the partition has a sealing function of preventing inflow of a large amount of an outside fluid into the pressure reduction zone, and a treating function of treating the wall surface by being moved in a required manner. In another aspect, the partition has the above sealing function, and a travelling function of moving the device, by being rotated about an axis of rotation slightly inclined to an axis which is substantially perpendicular to the wall surface.
