    Abstract: A hand vacuum cleaner is provided with a first cyclonic cleaning stage, a pre-motor filter and a fluid flow motor. The first cyclonic stage has a bottom end, an upper end spaced longitudinally from the bottom end along a first stage axis, an air inlet and an air outlet, the first cyclonic cleaning stage comprising a first cyclone chamber and a first dirt collection region, the first dirt collection region having an end wall at the bottom end that is openable to empty the first dirt collection region. The pre-motor filter is positioned downstream from the first cyclonic cleaning stage and spaced from the openable end wall of the first dirt collection region in a direction of the first stage axis. The fluid flow motor is downstream from the pre-motor filter. The pre-motor filter is removable in the direction of the central longitudinal axis through an opening in an upper end of the hand vacuum cleaner

    Abstract: A surface cleaning apparatus has a cyclone chamber provided in an air flow path. The cyclone chamber has a screen assembly with an outlet section, a longitudinally spaced apart distal section and a longitudinally extending porous section. The outlet section includes a non-porous member extending longitudinally inwardly an outlet section length from an outlet end of the outlet section to a longitudinally inwardly positioned inlet end of the outlet section. The outlet end of the outlet section overlies a cyclone air outlet. The porous section extends longitudinally inwardly from an outlet end of the porous section that is located at the inlet end of the outlet section. The outlet section length is at least as long as the cyclone outlet port length.
