Abstract
In a vacuum cleaner with a motor suction assembly ( ) comprising a motor part and a suction part ( ) providing a carrier air stream and a cooling air stream, respectively, the motor suction assembly ( ) is built into a cover ( ) with a cylindrical cavity ( ). The cover ( ) separates the carrier air stream from the cooling air stream, said cover thus being sealed ( ) against the motor suction assembly ( ) in such a way that the carrier air stream cannot be affected by the cooling air stream and vice versa. Furthermore, the motor suction assembly ( ) is surrounded and protected by the cover ( ). In this way, a construction is provided using only one cover, eliminating the need to position two covers, one of which solely serves to separate the air streams, while the other cover, together with the first one, provide a compartment for receiving the motor suction assembly ( ). Thus, in other words, two covers are replaced by a universal cover ( ).
