Surface cleaning apparatus

A surface cleaning apparatus comprising:

• (a) a cyclone chamber having a longitudinal axis defining a longitudinal direction, a first end having a first end wall, a longitudinally spaced apart second end having a second opposed end wall, a cyclone chamber sidewall extending between the first and second end walls, a cyclone air inlet, a cyclone air outlet and a dirt outlet, wherein, at a location of the dirt outlet, the cyclone chamber has a cyclone chamber width in a direction transverse to the longitudinal axis;
• (b) a dirt collection chamber having a first end wall positioned proximate the second opposed end wall of the cyclone chamber, a second opposed end wall that is longitudinally spaced apart from the first end wall of the dirt collection chamber and a dirt collection chamber sidewall;
• and,
• (c) a suction motor in fluid communication with the cyclone chamber,
• wherein the dirt collection chamber sidewall has a first sidewall portion and a second sidewall portion,
• wherein the first sidewall portion extends outwardly from the cyclone chamber sidewall to a distal end of the first sidewall portion, the distal end is spaced outwardly from the cyclone chamber sidewall,
• wherein the second sidewall portion extends from the distal end towards the second opposed end wall of the dirt collection chamber,
• wherein the dirt outlet faces towards the cyclone chamber sidewall, and
• wherein the second sidewall portion has a width in a direction transverse to the longitudinal axis that is greater than the width of the cyclone chamber.
