摘要： A method for cleaning first and second filters of a suction device for cleaning purposes is provided. The suction device has a dirt collection container with a suction inlet. The dirt collection container is subjected to negative pressure via first and second suction lines, respectively, following the first and second filters. First and second closing valves close first and second external air inlets, respectively, into the first and second suction lines. For cleaning the filters, the closing valves are opened, subjecting the filters to external air on the clean space side. The dirt collection container is subjected to negative pressure via the first suction line and first filter by a first suction unit and via the second suction line and second filter by a second suction unit. The suction lines are sealed off relative to each other on the clean space side at least during the cleaning of the filters.
