1. A reconfigurable upright surface cleaning apparatus comprising:
- a) an air flow passage extending from a dirty air inlet to a clean air outlet;
b) a floor cleaning unit comprising a surface cleaning head comprising the dirty air inlet and a handle drivingly connected thereto, the handle moveable between a storage position and a rearwardly inclined floor cleaning position; and
,c) a surface cleaning unit removably mounted to the floor cleaning unit and comprising;
(i) a first cyclone unit positioned in the air flow passage, the first cyclone unit comprising at least one cyclone comprising a cyclone air inlet, a cyclone air outlet, a cyclone axis and an axially extending outlet conduit;
(ii) a pre-motor filter positioned in the air flow passage downstream from the conduit;
(iii) a suction motor positioned in the air flow passage downstream from the pre-motor filter and having a suction motor axis; and
,(iv) the air flow passage includes a first air flow path portion that extends from the outlet conduit to the pre-motor filter and a second air flow path portion that extends from the pre-motor filter to the suction motor, wherein air travels downwardly through the first and second air flow path portions when the handle is the storage position,wherein the first cyclone unit is positioned above the suction motor when the surface cleaning unit is mounted to the floor cleaning unit.
