Dust and allergen control for surface cleaning apparatus

A system comprising a vacuum cleaner comprising a dirt collection region and an apparatus for receiving dirt from the dirt collection region of the vacuum cleaner, the dirt collection region has an openable door, the apparatus comprising:

• (a) an air flow passage from an inlet port to a clean air outlet, the dirt collection region of the vacuum cleaner is removably positionable in air flow communication with the inlet port wherein, when the dirt collection region of the vacuum cleaner is positioned in flow communication with the inlet port, the openable door of the dirt collection region of the vacuum cleaner is positioned interior the apparatus;
• and,
• (b) an air treatment member positioned in the air flow passage downstream from the inlet port, the air treatment member comprising an apparatus dirt collection region,
• wherein the apparatus is configured to be free standing on a floor and, when the apparatus is standing on the floor, the apparatus has an upper end which has the inlet port, and
• wherein, when the dirt collection region of the vacuum cleaner is positioned in flow communication with the inlet port and when the system is in an emptying mode of operation, a motor and fan assembly of the vacuum cleaner sucks air from the dirt collection region of the vacuum cleaner and expels air to ambient as dirt, which has been accumulated in the dirt collection region of the vacuum cleaner, travels to the air treatment member of the apparatus.
