Abstract: The invention relates to an apparatus for removing, by partial vacuum, particles, liquids etc. from a substrate (7). The apparatus includes a connection conduit (3) which is common to a plurality of channels (5a, 5b, 5c, etc.), and distributes partial vacuum to the one ends of the channels (5a, 5b, 5c, etc.), the conduit being arranged to be connected (at 4) to a source of partial vacuum establishing requisite partial vacuum at the one ends of the channels (5a, 5b, 5c, etc.). The other ends of the channels (5a, 5b, 5c, etc.) are obliquely inclined in relation to that substrate (7), from which material is to be removed, for the purpose of retaining the other ends of the channels (5a, 5b, 5c, etc.) open against the substrate (7) on abutment thereagainst, at least that space between said other ends and substrate which is hereby created being bridged by a suitably somewhat resilient portion (2a) which is arranged to seal from the other ends of the channels (5a, 5b, 5c, etc.) against the substrate (7).
