The invention is based on a dust and chip removal device, in particular for sanding hand power tools (10), having a transport channel (12, 14), via which the dust and chips can be directed into a storage container (16) secured to the hand power tool (10) in particular, and having a dust and chip retaining device that comprises a retaining element (18, 20, 22, 24) to prevent the dust and chips from flowing back out of the storage container (16). It is proposed that the retaining element (18, 20, 22, 24) comprises at least one passage (28, 30, 32, 34) that is closed by means of a holding force of an elastic element, and the passage (28, 30, 32, 34) opens automatically against the holding force starting at a certain delivery pressure, and the elastic element automatically closes the passage (28, 30, 32, 34) below a certain delivery pressure.
