  • Patent number: 7162771
    Abstract: A floor cleaning machine with dust control apparatus can assist in capturing dust created as a by-product during normal operations. The dust control apparatus is particularly applicable to propane-powered burnishers that use rotating pads to remove built up wax from hard surface floors. A floating scoop is attached to a floating hoop assembly to direct dust away from the rotating pad. The scoop is located tangentially to the housing that surrounds the rotating pad. An inlet to the housing facilitates airflow through the housing to pick up dust, which exits through the scoop. A containment canister with removable filter is in communication with the scoop. The air and entrained particulate (dust) swirls around the filter in a circular flow path to help separate the particulate from the air. The filtered air exits the canister and returns to the atmosphere.
