Abstract

A floor-type vacuum cleaner includes a housing and rollers attached to the housing that are configured to provide movement of the housing. Each roller is disposed on a roller axle so as to be rotatable. At least one of the rollers includes a rigid hub and an air-filled, rubber, resilient, damping tire. Alternatively, at least one of the rollers has a damping property and includes alternating concentric layers of rigid and flexible components, with air being disposed between at least one of the rigid components and at least one of the flexible components.
