FIELD: personal use articles.

SUBSTANCE: invention relates to a vacuum cleaner, namely, to a specific device to be used in a vacuum cleaner. An inlet device (200) is described with multiple holes, as well as a vacuum cleaner (100), where an inlet device is arranged. The inlet device (200) includes an upper body (201), comprising an auxiliary suction hole (231), formed in it, a lower body (202), engaged with the upper body. The inlet device (200) additionally comprises the main suction hole (203), formed in it, and a gate (240), formed in the upper body, every of the auxiliary channel (230) of the flow and a channel (210) of the gate flow is formed between the upper body and the lower body, the gate (240) opens an auxiliary suction hole (230) and closes the upper end of the channel (210) of gate flow with vacuum strengthening at the lower part of the lower body. Therefore, a permanent contact force is maintained between the inlet device and a cleaned surface.

EFFECT: development of an inlet device, where a suction force between the inlet device and the cleaned surface remains relatively permanent.
