Abstract: A vacuum cleaner for use in cleaning very hot crematory ovens has a suction head mounted on side wheels, and connected to a central fitting which receives compressed air through a stiff metal air supply pipe. An expansion pipe extends upwardly from the central fitting and is tipped frontwardly. The compressed air passes through the central fitting which incorporates a vacuum eductor which draws air flow in from the vacuum head. The hot air discharges through a filter cap at the upper end of the expansion pipe which retains a filter assembly of multiple screens against the upper end of the expansion pipe. Dust and small particles pass through the filter assembly to be carried away by hot air up the crematory chimney. Larger particles are retained by the filter assembly, and may be discharged downwardly from the vacuum head into a receptacle when the input compressed air is discontinued.
