a first arm, attached by a bendable connection to and in fluid communication with the leading central portion and configured and arranged to be relatively moved past the adjacent surface trailing the leading central portion in the travel direction, and to supply the pressurized medium to the adjacent surface to clean it; and a second arm attached by a bendable connection to and in fluid communication with the leading central portion and configured and arranged to be relatively moved past the adjacent surface trailing the leading central portion in the travel direction, and to supply the pressurized medium to the adjacent surface to clean it; wherein the first and second arm are joined to the opposite ends of the leading central portion to form an angle (α) in relation to each other, wherein each arm comprises at least one cleaning member, wherein said leading central portion is arranged so that said arms are torsionally stiff in relation to each other such that a rotation of one of said arms results in a similar rotation of every other arm, and wherein said at least two arms and the leading central portion are encased in an outer profile that is arranged to absorb an impact to protect said inner profile, the outer profile having a central portion corresponding to the leading central portion and first and second end portions corresponding respectively to the first and second arms, each end portion being joined to the central portion of the outer profile to form the angle (α) in relation to each other. ### Claim 2 (depends on 1) Cleaning device according to claim 1, wherein each of said first and second arm comprises a plurality of openings, each opening comprising threaded sections for mounting of the cleaning member onto the cleaning device. ### Claim 3 (depends on 1) Cleaning device according to claim 1, wherein said cleaning member comprises a nozzle that is supplied with the presssurized medium for spraying towards the adjacent surface. ### Claim 4 (depends on 3) Cleaning device according to claim 3, wherein each said nozzle is arranged to be adjusted in relation to said surface by rotation of said at least two arms. ### Claim 5 (depends on 1) Cleaning device according to claim 1, wherein said inner profile comprises tubular members, and said outer profile comprises tubular members having respective diameters larger than diameters of the inner profile, and wherein said outer profile comprises openings corresponding to nozzles of the inner profile to allow passage of the pressurized medium therethrough. ### Claim 6 (depends on 5) Cleaning device according to claim 5, wherein said outer profile is further equipped with at least one dampening member for absorbing an impact and said dampening member is mounted so as to avoid blocking or hindering an operation of said cleaning member. ### Claim 7 (depends on 5) Cleaning device according to claim 5, wherein said inner profile comprises at least one bearing member per arm, said bearing members being arranged to allow for the inner profile to be rotationally displaceable in relation to the outer profile. ### Claim 8 (depends on 1) Cleaning device according to claim 1, wherein said device is connected to a fastening structure arranged to enable for axial adjustment of the position of the device. ### Claim 9 (depends on 8) Cleaning device according to claim 8, wherein said fastening structure comprises an outer cylinder and an inner cylinder which inner cylinder is displaceably arranged in an axial and a rotary direction within the outer cylinder, said fastening structure further comprising a locking member and said inner cylinder comprising a coupling means, where the locking member and the coupling means are arranged to cooperate with each other for limiting the displacement of the inner cylinder in axial and rotary direction, and wherein the device is connected to said inner cylinder. ### Claim 10 (depends on 9) Cleaning device according to claim 9, wherein said locking member comprises a friction screw and said coupling means comprises a groove with a width and length, wherein said friction screw and said groove are arranged to cooperate for adjusting the inner cylinder and allowing the cleaning device to move in axial and rotary directions respectively. ### Claim 11 (depends on 1) Cleaning device according to claim 1, wherein said device is made of steel material, preferably stainless steel material, preferably acid resistant stainless steel. ### Claim 12 (depends on 1) Cleaning device according to claim 1, wherein the leading central portion includes at least one spray nozzle, configured and arranged to supply the pressurized medium to the adjacent surface to clean it. ### Claim 13 (depends on 1) Cleaning device according to claim 1, wherein the first arm and the second arm are each connected, at respective ends distal from the leading central portion, to respective fastening structures that secure the cleaning device to a frame.
