  • Patent number: 8695157
    Abstract: A vacuum cleaner with a vacuum, a filtering unit, a switching device for switching between a vacuum cleaning and filter cleaning modes, and a separating unit is disclosed. In the vacuum cleaning mode, the vacuum forces a first air stream in a first air stream path through the filtering unit, in a first direction, to filter out dust from the dust laden air stream. In the filter cleaning mode, the vacuum forces a second air stream in a second air stream path through the filtering unit, in a second direction reverse to the first direction, to remove dust from the filtering unit. In the filter cleaning mode, the separating unit is in the air path between the vacuum and the filtering unit to separate dust removed from the filtering unit. In the vacuum cleaning mode, the separating unit is not in an air stream path.

  • Patent number: 8448292
    Abstract: A cyclone separator for a vacuum cleaner. The separator has a cyclone chamber, an air entrance device having a flow passage arrangement therethrough for introducing an air stream into the cyclone chamber in a manner that causes the air stream to swirl in the cyclone chamber to remove dust from the air stream, and an air outlet for emitting the air stream from the cyclone chamber. The entrance device has a control member that is operable to alter the flow passage arrangement such that one or more properties of the air stream in the cyclone chamber are affected by the alteration. The flow passage arrangement has a first path and a second path, and the control member is operable to alter the flow passage arrangement by redirecting the air stream from the first path to the second path.
