    摘要： A vacuum is provided with multiple exhaust points which provide for quieter, lower velocity discharge of the air from the vacuum source. The multiple exhaust points are supplied from a radially extending chamber that is defined between upper and lower panels. The radially extending chamber has both vertical and radial sections that operate to slow the velocity of the exhaust air to reduce the noise generated by the vacuum.

    摘要： A vacuum including a housing, a suction device disposed within the housing, at least one axle mounted to the housing at one or more mounting points, and a plurality of wheels mounted to the axle, wherein the axle is operable to flex about the one or more mounting points to absorb an impact force. The vacuum may also include at least one rail mounted to the housing at a plurality of mounting points and at least one caster wheel rotatably fixed to the rail. The at least one rail is operable to pivot about an axis partially defined by at least one of the mounting points in response to input forces, and a plurality of spring elements are operable to resist said pivoting, damping the input forces.
