Abstract
An upright vacuum cleaner for cleaning a surface includes an upper body with a dust collection container received therein, and a base unit. A carriage is configured to provide movement of the base unit on the surface. A motor-fan unit is disposed in the base unit and configured to provide a partial vacuum at the surface. The upper body is connected to the base unit by a tilting joint such that the upper body and base unit are tiltable relative to each other about a tilt axis extending horizontally when the upright vacuum cleaner is in a position of use. An air conduit is disposed rotatably with respect to the motor-fan unit and communicates with a suction side of the motor-fan unit.
