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.

A device capable of adhering to a wall surface by suction by the pressure of an ambient fluid and treating the wall surface, said device comprising a pressure receiver member, a partition provided on the pressure receiver member and facing toward the wall surface, the partition being movable relative to the pressure receiver member, said partition having a first end portion adapted to make contact with the wall surface to treat said surface, said partition defining a pressure reduction zone in cooperation with the pressure receiver member and the wall surface, means for creating a vacuum within the pressure reduction zone by discharging fluid from the pressure reduction zone, and a driving source mounted on the pressure receiver member for moving the partition with respect to the pressure receiver member; a rotating plate adapted to be rotated about an axis of rotation extending substantially perpendicular to the wall surface by the driving source, said partition having a second end portion connected to the rotating plate; and the rotating plate has formed therein an opening for communication between a first zone defined by the rotating plate, the partition and the wall surface and a second zone defined by the rotating plate and the pressure receiver member; a plurality of wall contacting members on the pressure receiver member; an annular seal member disposed between the pressure receiver member and the rotating plate, said seal member extending from its inner annular end connected to the pressure receiver member outwardly and toward the rotating plate and terminating at its outer annular end which is in contact with the rotating plate.
