A mobile apparatus for pneumatically blowing and suctioning fiber fly or lint from textile machines by means of blowing and suctioning means respectively connected to a common fan by means of nozzles and suction members which sweep past the textile machine and across the floor and between which there is positioned a filter to extract the fiber fly or lint which is adapted to be impinged periodically by the air-blast stream in the opposite direction to clean said filter and convey the fiber fly deposited on said filter into a collection bin. In order to position the apparatus immediately adjacent to the working area, the apparatus is designed to move on a trackway provided on one side of the textile machine. The drive means is adapted to be automatically de-energized and reversed by limit switches provided on the apparatus. The fan is a radial blower fan. The blower wheel thereof is rotatably mounted about a horizontal axis extending transversely to the direction of movement, is provided in the working area of the blowing and suction means and is impinged directly by the fiber fly. The suction means are located substantially below the fan and the filter associated with the pressure conduit leading to the blowing means is located thereabove, said pressure conduit being adapted to be separated from a filter box by a slide which simultaneously opens a by-pass valve, thus deflecting the air-blast stream against the upstream side of the filter, and establishes a connection between said filter box and a collection bin.
