Abstract A cleaning device for cleaning an adjacent surface includes at least a first and a second arm joined by an interconnection to form an angle (α) in relation to each other, wherein each arm comprises at least one cleaning member, wherein the interconnection is constructed and arranged so that the 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. ## Claims ### Claim 1 Cleaning device for cleaning of an adjacent surface, comprising at least a first and a second arm joined by an interconnection to form an angle (α) in relation to each other, wherein each arm comprises at least one cleaning member, wherein said interconnection 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. ### 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 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 a medium for spraying towards an object to be cleaned. ### Claim 4 (depends on 2) Cleaning device according to claim 2, wherein said nozzle is arranged to be adjusted in relation to said object by rotation of said at least two arms. ### Claim 5 (depends on 1) Cleaning device according to claim 1, wherein said interconnection is arranged to allow the angle (α) between said at least two arms to be altered by bending said interconnection. ### Claim 6 (depends on 1) Cleaning device according to claim 1, wherein said at least two arms are connected to each other via a middle portion, which middle portion preferably comprises at least one cleaning member. ### Claim 7 (depends on 1) Cleaning device according to claim 1, wherein said at least two arms and interconnection form an inner profile and said inner profile is encased in an outer profile that is arranged to absorb an impact in order to protect said inner profile. ### Claim 8 (depends on 7) Cleaning device according to claim 7, 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 9 (depends on 7) Cleaning device according to claim 7, wherein said inner structure comprises at least one bearing member per section, preferably at least two bearing members per section, said bearing members being arranged to allow for the inner structure to be rotationally displaceable in relation to the outer structure. ### Claim 10 (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 11 (depends on 10) Cleaning device according to claim 10, 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 12 (depends on 11) Cleaning device according to claim 11, 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 direction respectively. ### Claim 13 (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 14 A method for cleaning a surface, comprising: providing a cleaning device for cleaning of an adjacent surface, comprising at least a first and a second arm joined by an interconnection to form an angle (α) in relation to each other, wherein each arm comprises at least one cleaning member, wherein said interconnection 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, positioning the cleaning device at a distance from the surface to be cleaned so that each of said cleaning members is arranged at the same distance from said surface to be cleaned, adjusting the position of the cleaning members in relation to the surface to be cleaned by rotating at least one of the arms, and ejecting a cleaning medium through said cleaning members onto the surface to be cleaned. ### Claim 15 (depends on 14) The method according to claim 14, wherein the surface to be cleaned is arranged to move in relation to the cleaning device during the cleaning operation.
