<p>The vacuum cleaner has a series of vertical pockets to filter the air and collect the dust. The air is sucked up through a flexible hose, through a perforated frame and upwards towards the filter pockets. The dust impinges on the outsides of the filters then falls back into a collecting drawer beneath the hose inlet. The filtered air is channelled out of the pockets then down the side of the cleaner and out through an exit port underneath the chassis.</p> |
