A vacuum cleaner having a base to move on a surface, an intermediate member having a first and second passages, and a first joint connecting the base to the intermediate member to permit relative rotation between the base and the intermediate member about a first axis that is generally parallel to the surface and perpendicular to a direction of movement. An air passage connects a base inlet to the first intermediate member passage. A second joint connects a handle to the intermediate member and permits rotation between the intermediate member and the handle about a second axis that is parallel to a nominal direction of movement of the vacuum. The handle has a grip a dirt collector to receive and separate dirt from air. First and second passages connect the intermediate member passages to the dirt collector inlet and outlet. A vacuum fan draws air into the base air inlet, through the intermediate member, through the dirt collector, through the second handle air passage, and back into the intermediate member. At least one of the first and second passages jointing the intermediate member to the dirt collector is a flexible hose that is offset from the second axis and is adapted to flex to permit the handle to rotate relative to the intermediate member.
