Abstract
A vacuum cleaner having a base adapted to be moved on a surface to be cleaned, an inlet nozzle disposed on a lower surface of the base, a vacuum source, and a dirt receptacle. A lower handle is pivotally attached to the base at a lower pivot, and an upper handle is pivotally attached to the lower handle at an upper pivot. In one aspect, the vacuum cleaner includes an automatically-operated lower pivot lock that can restrict relative rotation between the lower handle and the base, and a manually-operated upper pivot lock that can restrict relative rotation between the upper handle and the lower handle. In another aspect, the vacuum cleaner includes a telescoping upper handle with electrical controls attached to the upper telescopic section of the upper handle. In still another aspect, the vacuum cleaner includes an exhaust vent located on an upwardly-facing surface of the base.
