Portable surface cleaning apparatus

A hand vacuum cleaner having an outer surface, the hand vacuum cleaner comprising:

• (a) an air flow passage extending from a dirty air inlet to a clear air outlet;
• (b) a housing having a housing front end, a housing rear end spaced apart from the housing front end in a rearward direction and a sidewall extending between the front and rear ends of the housing, the housing comprising a first portion that houses a suction motor that is positioned in the air flow passage, the suction motor having a suction motor axis of rotation;
• and,
• (c) a cyclone unit positioned in the air flow passage upstream from the suction motor, the cyclone unit comprising a cyclone unit front end, a cyclone unit rear end, a cyclone unit sidewall, a cyclone and a dirt collection region that is positioned forward of the cyclone, the cyclone unit front end having an openable door, the cyclone comprising a cyclone front end, a cyclone rear end, a cyclone air inlet, a cyclone air outlet and a cyclone axis of rotation which intersects the cyclone front end and the cyclone rear end, the cyclone air outlet comprising an assembly which includes a screen,
• wherein the assembly is moveable relative to the cyclone unit sidewall in a common direction with the cyclone axis of rotation whereby the assembly and the sidewall are separable from each other in a forward direction.
