Abstract The invention provides a vacuum cleaner (100) including an airflow path, dirt and dust collecting device arranged in the airflow path, a motor or fan unit (110) for causing air to flow along the airflow path and also arranged therein, a first filter (112) arranged immediately upstream of the motor or fan unit (110) and a second filter (114) arranged downstream of the motor or fan unit (110), wherein the arrangement is such that, when in use the dirt and dust collecting device are made accessible or removed for emptying or replacement, both filters (112, 114) are visible to the user. This arrangement encourages the user of the vacuum cleaner to regularly maintain both filters (112, 114), thus improving the performance of the vacuum cleaner (100).
In a vacuum cleaner comprising an airflow path, dirt and dust collecting means arranged in the airflow path, a motor or fan unit for causing air to flow along the airflow path the improvement which comprises; a movable cover covering a casing containing the dirt and dust collecting means which is cyclonic and containing the motor or fan unit with a first filter arranged upstream of the motor or fan unit and a second filter arranged downstream of the motor or fan unit during use, wherein air flows from the collecting means into the motor or fan unit through the first filter and away from the motor or fan unit through the second filter, wherein when the cover is opened, both filters are visible to the user and wherein the filters can be replaced when the filters have collected dust and dirt.
