Abstract (en)
Suction apparatus with a suction device (41) and a cyclone separator container (1), between which there is arranged a filter (31). For its cleaning the filter is arranged such as to be rotated, so that particles deposited on it are thus thrown off and collected in the container. When the filter is rotating, the suction inlet is closed, so that the excess pressure in the container caused by filter rotation does not cause the outward leakage of material thus separated. This can be done by the suction end of a suction hose (45) being recoupled to the container or to collection means (47, 49) connected thereto.
