Air treatment apparatus

A combination of a vacuum cleaner having a motor and fan assembly and a docking station for the vacuum cleaner wherein, when the vacuum cleaner is docked at the docking station, the docking station is operable to collect dirt from a dirt collection region of the vacuum cleaner, the docking station comprising:

• (a) a docking station air inlet that is connectable in fluid flow communication with the dirt collection region;
• (b) an air flow path extending from the docking station air inlet to a docking station air outlet;
• (c) a first cyclonic stage comprising a cyclone chamber and a docking station dirt collection region, the cyclone chamber having a cyclone chamber air inlet, a cyclone chamber air outlet and a cyclone axis of rotation, wherein, when the docking station is placed on a horizontal surface and is in operation, the cyclone axis of rotation extends generally vertically
• wherein the first cyclonic stage comprises a first stage air treatment chamber of the docking station,
• wherein when the vacuum cleaner is docked at the docking station, an air stream that is produced by the motor and fan assembly of the vacuum cleaner and that contains dirt collected in the vacuum cleaner is drawn through the docking station air inlet into the docking station where the air is treated to remove the collected dirt and a clean air stream is emitted from the docking station air outlet.
