Hand carryable surface cleaning apparatus

A surface cleaning apparatus comprising:

• (a) an air flow path extending from a dirty air inlet to a clean air outlet;
• (b) a suction motor provided in the air flow path;
• and,
• (c) a cyclone chamber provided in the air flow path, the cyclone chamber having a cyclone air inlet, a cyclone air outlet, an outlet end, an opposed end that is spaced apart in a longitudinal direction and a screen assembly, the cyclone air inlet having an outlet port that extends a cyclone outlet port length in the longitudinal direction, wherein the cyclone air inlet terminates at the outlet port that is provided in a peripheral sidewall of the cyclone chamber, the cyclone sidewall is parallel to the longitudinal direction whereby air enters the cyclone chamber at the peripheral sidewall of the cyclone chamber and is directed to flow though the cyclone air inlet in a tangential direction that is substantially perpendicular to the longitudinal direction, the cyclone air outlet is provided at the outlet end of the cyclone chamber, the outlet port having a first outlet port side and a longitudinally spaced apart second outlet port side located longitudinally inwardly from the first outlet port side,
• wherein the screen assembly comprises an outlet section, a longitudinally spaced apart distal section and a longitudinally extending porous section and the distal section is non-porous,
• and wherein the outlet section comprises a non-porous member extending longitudinally inwardly an outlet section length from an outlet end of the outlet section, which is located at the outlet end of the cyclone chamber, to a longitudinally inwardly positioned inlet end of the outlet section,
• and wherein the outlet end of the outlet section overlies the 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 to the second outlet port side,
• and wherein the distal section has a distal section length in the longitudinal direction that is greater than the cyclone outlet port length.
