发明名称 Vacuum cleaner and a filter assembly therefor
摘要 The invention provides a filter assembly for use in a vacuum cleaner. The vacuum cleaner includes an airflow path (18), a dirt and dust collecting device arranged in the airflow path (18), a motor or fan unit (10) for causing air to flow along the airflow path (18). A first filter (12) is arranged immediately upstream of the motor or fan unit (10) and a second filter (14) is arranged downstream of the motor or fan unit (10), wherein the first and second filters (12, 14) are connected together so as to form the single filter assembly. The connection of the filters (12, 14) encourages the user of the vacuum cleaner to regularly maintain both filters (12, 14) thus improving the performance of the vacuum cleaner.
