<p>A vacuum cleaner nozzle includes a casing (1), a plate (2) mounted on the bottom of the casing and including suction grooves (3, 4) surrounded by flat parts (5, 6, 7), and an aperture (8) adapted for communication with a suction source via a suction passage (9). The invention is characterized in that the casing encloses a space (10) which is delimited downwardly by that surface (11) of the plate (2) which faces towards the casing interior, and in that the space (10) accommodates a cooling element (12) which is intended to lie against, or essentially against, the plate surface (11) and thereby cool the surface.</p> |
