A vaccum cleaning device comprising an enclosure (20) containing a chamber (30) in which is located at least one flexible wall such as a bag (2) designed to stop solid particles while letting through the air, and containing a compartment (40) provided with a movable tray (41) located beneath the chamber (30) in order to catch the solid particles which fall by the force of gravity. The device is characterized in that it includes a means (5) for forming a sealed connection between the flexible wall (2) and the tray (41), the latter comprising at least one inlet (48-49) for air to be filtered. In a preferred embodiment, the flexible wall (2) is secured by frame (3) the edge of which carries a flexible seal (5) so that the assembly (1) thereby formed is self-contained and interchangeable without needing to be dismantled.
