Abstract

The invention relates to a vacuum cleaner (10) comprising a dust collection container (11) and a suction head (13) that can be placed on the dust collection container, said head having at least one suction assembly that is in fluid connection with the dust collection container via a suction inlet (30). A filter cage (36) that projects into the dust collection container is situated on the suction inlet and a filter element (62) can be detachably fastened to said filter cage. To improve the vacuum cleaner (10) in terms of reducing the risk of a user placing the suction head vertically on the floor to empty the dust collection container, according to the invention, a support element (54) juts out from the underside of the filter cage and is radially offset in relation to the central axis (52) of the cage.
