A vacuum cleaner has a vacuum cleaner housing and an exchangeable filter with through opening arranged in the housing. A holding arm connected with its upper end to the vacuum cleaner housing penetrates the through opening. A fastening member is detachably connected to the lower end of the holding arm for securing the filter to the holding arm. The lower end of the holding arm has a radial recess, and the fastening member has engagement elements engaging the radial recess when the filter is secured on the holding arm. The engagement elements block removal of the fastening member from the lower end of the holding arm. The fasting member has an actuating ring moveable between a locked position, in which the engagement elements secure the fastening member against removal from the holding arm, and a release position, in which the fastening member is removable from the holding arm.
