Abstract
A vacuum cleaner comprises a base which has a surface cleaning nozzle and a wheel housing which is moveable between a raised position and a lowered position. Wheels are rotatably mounted on the wheel housing. An abutment arm is attached to said wheel housing at a fixed position relative to said wheels. A handle structure is pivotally mounted on the base and moveable between an upper storage position and a lower operating position. A protrusion, which is attached to the handle, structure, is positioned and ad to engage the abutment arm. A spring is provided which bias the wheel housing to its raised position. As the handle structure is pivoted from the lower operating position to the upper storage position, the abutment arm engages the protrusion moving said wheel housing to its lower position and consequently raising said nozzle.
