VACUUM CLEANER

摘要

The present disclosure relates to a vacuum cleaner (1) comprising a separating unit (34), a vacuum source (31) for creating a negative air pressure, and a downstream filter (33). The vacuum cleaner is configured to operate in a vacuum cleaning mode, and is switchable to a filter cleaning mode, wherein the vacuum source is connected to the downstream filter to force an airstream therethrough in a reverse direction in order to remove dust from the downstream filter, and the separating unit is arranged to separate dust, released by the downstream filter, from the airstream. The separating unit has first and second sub-separators (35, 37), which are connected in parallel in the vacuum cleaning mode, and are connected in series in the filter cleaning mode. This provides convenient cleaning of the downstream filter.
