Abstract

A vacuum cleaner ( 10 ) includes a handle assembly ( 22 ) pivotally coupled to a foot ( 42 ). The handle assembly ( 22 ) includes an air treatment member, an actuator ( 34 ) centrally arranged on a rear side of the handle assembly ( 22 ) and a cord reel assembly ( 14 ) arranged on a front side of the handle assembly ( 22 ). The cord reel assembly ( 14 ) includes a cord reel ( 30 ) and a cord ( 26 ) configured to be coupled to an AC power source and provide power to the suction source. The cord reel ( 30 ) is switchable between a first state, in which the cord reel ( 30 ) winds the cord ( 26 ), and a second state, in which the cord reel ( 30 ) does not wind. The actuator ( 34 ) is moveable between a first position and a second position. In response to the actuator ( 34 ) moving from the first position to the second position, the cord reel ( 30 ) switches from the second state to the first state.
