The active portion is in the form of a single blade, made from a flexible or semi-rigid material, intended to be moved in one direction against the planar surface. There is an internal cavity connected to a mechanism for sucking air and liquid. At a distal portion of the blade and behind the ridge to be moved on the surface, two walls together form an angle and meet at the ridge. A first wall is presented first towards the surface to be scraped during a scraping operation having, alongside and close to the ridge, a plurality of holes opening into the cavity. ## Claims ### Claim 1 A suction device for sucking air and liquid from a planar surface, said suction device comprising: a single blade, being comprised of a flexible material and moveable in one direction against said planar surface, the blade comprising an internal cavity connected to a means for carrying out said suction of air and liquid and defined by a contact wall and an upper wall at a distal portion of the blade and behind a ridge moveable over said planar surface, said contact wall and said upper wall forming an angle and joining each other at said ridge, said contact wall being moveable first to said planar surface during a scraping operation, said contact wall having a plurality of holes connected to said internal cavity, said holes being arranged along and close to said ridge. ### Claim 2 A suction device for sucking air and liquid from a planar surface, said suction device comprising: two blades, each blade being comprised of a flexible material and arranged so as to form an angle between the blades and to join each other according to a ridge, the blades being made integral, in order to form a single blade member moveable in one direction against said planar surface, said single blade member having an internal cavity resulting from angled positioning and from making said two blades integral, said internal cavity being connected to means for carrying out suction of air and liquid, wherein one blade of said two blades is presented first to said planar surface during a scraping operation, said one blade having a plurality of holes along and close to said ridge, said holes ending in said internal cavity. ### Claim 3 (depends on 1) The suction device according to claim 1, further comprising another plurality of holes, on both sides and close to the ridge, said another plurality of holes ending in said internal cavity. ### Claim 4 (depends on 1) The suction device according to claim 1, wherein each hole has a chamfer on a respective outer side. ### Claim 5 (depends on 1) The suction device according to claim 1, wherein said internal cavity is provided with reinforcing means extending between two sides of said internal cavity. ### Claim 6 (depends on 5) The suction device according to claim 5, wherein the reinforcing means comprises applied elements inserted between said two sides of said internal cavity. ### Claim 7 (depends on 6) The suction device according to claim 6, wherein said applied elements are comprised of a plurality of parallel walls each parallel wall extending between said two sides of said internal cavity, and connected by at least one longitudinal beam. ### Claim 8 (depends on 7) The suction device according to claim 7, further comprising: non-return means trapping residual water resulting from suction, said non-return means being incorporated with said internal cavity. ### Claim 9 (depends on 8) The suction device according to claim 8, wherein each non-return means comprises a truncated channel permitting communication between one hole among said plurality of holes, said internal cavity being connected to said means for carrying out suction of air and liquid. ### Claim 10 (depends on 1) The suction device according to claim 1, further comprising: a flat strip on a free end of the blade, said flat strip at said distal portion of the blade, said contact wall having a set-back forming an angle with said flat strip, said set-back being extended by a portion of a wall sloping with respect to the blade, said plurality of holes being located in said portion of said wall. ### Claim 11 (depends on 1) The suction device according to claim 1, wherein the holes are formed in a distal edge of said contact wall and are separated two-by-two by a strip of material having a substantially triangular shaped end on a distal side, wherein a tip of said strip of material is directed towards said ridge so as to form a point of attachment to said upper wall. ### Claim 12 (depends on 1) A scraper blade for a suction device according to claim 1.
