    Abstract: An apparatus and method for filtering a dirty air stream in a vacuum cleaner to obtain a clean air stream comprises subjecting the dirty air stream to a first cyclonic separation stage (32) to obtain a partially cleaned air sream and subjecting the partially cleaned air stream to an electronic filtration stage (50) and optionally a second cyclonic separation stage (60) to obtain the clean air stream. The electronic filtration stage (50) is optionally removable with a cyclonic cleaning stage from the vacuum cleaner. The electronic filtration stage (50) is optionally an electrostatic precipitator which utilizes air flow through the vacuum cleaner to generate the voltage used by the electrostatic precipitator.

    Abstract: A vacuum cleaner head has one or more of the following improvements. The vacuum cleaner head having a casing having a dirty air inlet, a housing mounted above the dirty air inlet and moveable with respect to the dirty air inlet and a brush roatably mounted within the housing and moveable with the housing for improving the air flow of the dirty air around the brush into the vacuum cleaner head. The vacuum cleaner head having a dirty air inlet has an associated restricting member which is operable to reduce the size of the dirty air inlet thereby increasing the velocity of the air entering the air flow path. The vacuum cleaner head is provided with cutting means positioned in the air flow path of the vacuum cleaner head to reduce the size of elongate particulate material entering the dirty air inlet. A secondary air flow path positioned to provide enhanced edge cleaning. A pressure sensor which is drivingly connected to the brush to move the brush with respect to the dirty air inlet in response to the air pressure in the air flow path to the vacuum cleaner head. A vacuum cleaner is provided with an automatic actuator to engage the edge cleaning of a vacuum cleaner head when the user vacuums adjacent a wall, furniture or the like.

    Abstract: A vacuum cleaning head for a vacuum cleaner includes structure for inducing vortices in the incoming air travelling between the sole plate and the surface to be cleaned. The vortices assist in entraining dust and dirt particles raised from the surface to be cleaned by a cleaning implement whic h may be a brush, beater bar or the like. The axis of the vortices is substantially parallel to the surface to be cleaned and the vortices bring the rotating ai r substantially adjacent to and preferably in contact with the surface to be cleaned.

    Abstract: A vacuum cleaner comprises a housing having a clean air outlet, a cleaning member having a dirty air inlet, an air flow path extending from the dirty air inlet to the clean air outlet, a primary filtration stage comprising at least one cyclone particle separator positioned in the air flow path downstream from the dirty air inlet, the air flow path including the primary filtration stage having an operational back pressure from 2 - to 12 kpa when the air flow path is not blocked, and a motor and fan assembly having an air flow rate sufficient to transport the dirt in an air stream to the primary filtration stage and to cause cyclonic separation in the cyclone particle separator of particulates suspended within the air stream over the normal operational range of back pressure of the vacuum cleaner when the air flow path is not blocked.
