Abstract

An upright vacuum cleaner for cleaning a surface. The vacuum cleaner includes an upper body having a dust collection container, a base unit having a suction mouth and a carriage for moving the base unit on the surface. A motor-fan unit is included and is disposed outside the upper body. The motor-fan unit is operable to create a partial vacuum on the surface. A combined coaxial conduit is disposed in a transition region to the upper body. The combined coaxial conduit includes a first air conduit from the suction mouth to the upper body and a second air conduit from the upper body to the motor-fan unit.
