Abstract
A method and apparatus for influencing movement of a handle of a floor treatment device, such as a vacuum. The floor treatment device may include a handle portion that is attached to a base, which includes a floor treatment portion. The handle portion may be pivotally movable about a rotation axis relative to the base between at least first and second positions, where the rotation axis lies in a vertical plane that includes a longitudinal axis of the handle when the handle portion is in the first position and the longitudinal axis is a non-vertical position. A pivot assist device may apply a bias to the handle portion that urges the handle portion to move from the second position to the first position, e.g., to help support the weight of the handle when a user steers the floor treatment device across a floor.
