Abstract

An air flow channel (4) of domestic suction or blowing apparatus, especially a vacuum cleaner, has a structuring of the inner wall of the air flow channel leading to a micro-turbulence. The structuring is designed to be scaly. The structuring is designed to be groove-shaped and unordered. The structuring is designed on the largest part of the inner wall of the air flow channel from a suction air inlet to the suction fan inlet. The structuring is designed also on the largest part of the inner wall of the air flow channel from the fan outlet to a fan air outlet. The structuring is designed in the 100th to 10th of a millimetre range.
