Abstract:
A hand vacuum cleaner has a cyclonic stage comprising an openable front wall provided at the front end of the cyclonic stage. A pre-motor filter is positioned in the air flow passage downstream from the cyclone air outlet and rearward of the cyclone sidewall. The pre-motor filter has a diameter in a direction transverse to the cyclone axis that is larger than a diameter of the cyclone air outlet in the direction transverse to the cyclone axis. The pre-motor filter has an outer perimeter defining a volume and the cyclone axis and the motor axis each extend through a centre of the volume. The cyclone axis is generally parallel to the motor axis. When the openable front wall is opened, the front end of the cyclone stage is opened and has an opening, the opening has a diameter in the direction transverse to the cyclone axis, and the rear end of the cyclonic stage has a diameter that is generally equal to the diameter of the opening. The cyclonic stage is removable from a cleaner body which houses the suction motor with the openable front wall in a closed position. When the first cyclonic stage is removed, the pre-motor filter is accessible for removal.
