Title: Vacuum cleaner carriage and tank assembly

Abstract: A vacuum cleaning apparatus is disclosed in which a wheeled carriage supports a plurality of different size collection tanks on a pivot support rod extending between upward extending portions of a handle frame mounted on the carriage base. The rear of each of the tanks includes a transverse groove dimensioned to slip onto the pivot support rod. The tanks may be pivoted about the support rod to dump the contents contained therein. A carriage anti-tilt support, pivotally mounted on the carriage, prevents tipping of the carriage during tank dumping.
