Abstract: A vacuum cleaner system having a vacuum cleaner with a first housing, an air inlet, an air outlet, a motor fan unit for creating an airflow from the air Inlet to the air outlet, a battery for powering the motor fan unit, and a first unit for charging the battery, and a charger having a second housing with a second unit for changing the battery. The first unit is connected to the battery and the second unit is adapted to he connected to an external power source, and the first unit and the second unit are adapted for wireless power transfer from the second unit to the first unit.

Abstract: A vacuum cleaner comprising a vacuum cleaner housing (10) with a vacuum source and an inlet (13) for dust-laden air communicating with the vacuum source. The vaccum cleaner has a separation system for particles separated from the airflow that is placed after the inlet as seen in the airflow direction. The separated particles are collected in a bag (21) of a mainly airtight material. The vaccum cleaner is provided with a closing and/or sealing arrangement by which a bag (21) inserted into the vaccum cleaner is closed and/or sealed before the bag is removed from the vacuum cleaner.

Abstract: A device for a vacuum cleaner that has a vacuum source (12) connected to an inlet channel, and an outlet channel for air flowing through the vacuum cleaner. The vacuum cleaner includes a device for electrostatically charging a feather-duster (20) or a micro fiber type with static electricity.

Abstract: A device for a vacuum cleaner having a vacuum source communicating with an inlet channel and an outlet channel for air flowing through the vacuum cleaner. The vacuum cleaner includes a holder (19) for a dust pick-up tool such as a feather-duster (20) or a micro fiber-type duster/. The holder is provided with a chamber (21) which, by operation of a valve (28,30), can be connected to the inlet or outlet channel so that the dust pick-up tool is cleaned by the air flowing through the chamber.
