FIELD: human vital needs satisfaction.

SUBSTANCE: vacuum cleaner nozzle (2) has a base (10) and a suction opening (8) in the base (10). An array (35) of flexible valves (40) protrudes from the base (10). Flexible valves (40) are configured to act on the surface to be cleaned. Flexible valves (40) are separated from each other by a gap to allow rubbish passage between them in a predetermined arrangement. The predetermined arrangement of the flexible valves (40) is configured to create a non-linear flow path through the array (35) of flexible valves (40) between the base end (15, 16) and the suction opening (8). The gap (39) between the first and second rows (36, 37) of valves (40) is substantially equal to or greater than the space (43) between adjacent flexible valves (40) in each of the first and second rows. This invention also relates to a vacuum cleaner (1) including a vacuum cleaner nozzle (2).
