ABSTRACT:
A vacuum cleaner comprising a fan assembly which via a chamber encloses a dust container and communicates with an inlet sleeve for dust laden air. The inlet sleeve is via a hose connected to the nozzle of the vacuum cleaner. The walls of the chamber are provided with guides for a stiff collar which is part of the dust container. The guides extend mainly perpendicular to the axial direction of the inlet sleeve. The vacuum cleaner also includes a flexible inflatable means which is placed about the inlet sleeve. When starting the fan the flexible means is inflated by means of the pressure difference between atmosphere and the chamber thereby preventing dust laden air from flowing outside the dust container.
