A vacuum cleaner, comprising a housing, in which a dust chamber is embodied for housing a dust separator, which may be sealed by means of a dust chamber lid, mounted on the housing and a housing for accessory pieces which can be closed by the dust chamber lid. According to the invention, the contamination of the accessory pieces by dust from the dust chamber may be prevented, whilst maintaining easy access to the accessory pieces by means of the dust chamber lid, whereby the housing is embodied as an adjoining chamber, directly adjacent to the dust chamber which is separated from the dust chamber in a dust-tight manner by means of a separating wall. The above has the advantage of permitting a user to remove an accessory piece without getting dirty.
