Abstract
A surface cleaning head has a cyclone assembly with a cyclone assembly air inlet port and a cyclone assembly air outlet port, a first air flow path extending from a dirty air inlet to the cyclone assembly air inlet port, and a second air flow path extending from the cyclone assembly air outlet port to a suction motor air inlet. The cyclone assembly moveable from a cleaning position in which the cyclone assembly air inlet port is in communication with an outlet port of the first air flow path and cyclone assembly air outlet port is in communication with an inlet port of the second air flow path to a removal position in which the cyclone assembly air inlet port is spaced from the outlet port of the first air flow path and cyclone assembly air outlet port is spaced from the inlet port of the second air flow path.
