The invention provides a vacuum cleaner comprising an airflow path having a dirty air inlet and a clean air outlet, a fan for drawing an airflow along the airflow path from the dirty air inlet to the clean air outlet, a motor for driving the fan, separating apparatus for separating dirt and dust from the airflow, a pre-motor filter arranged upstream of the motor and a post-motor filter arranged downstream of the motor, wherein both the pre-motor filter and the post-motor filter are cylindrical filters. The invention further provides a vacuum cleaner comprising an airflow path having a dirty air inlet and a clean air outlet, a fan for drawing an airflow along the airflow path from the dirty air inlet to the clean air outlet, a motor for driving the fan, separating apparatus for separating dirt and dust from the airflow, a pre-motor filter arranged upstream of the motor and a post-motor filter arranged downstream of the motor, wherein the post-motor filter is housed in a casing containing a plurality of slots or apertures, the slots or apertures forming the clean air outlet and being arranged such that, in use, the airflow is diffused as it leaves the clean air outlet.
