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.

Floor cleaning machine with dust control apparatus and associate method of use

A floor surface treatment apparatus having a wheeled vehicle including a support for a floor surface treatment unit, the support being moveable relative to the vehicle. A floor surface treatment unit is pivotally carried by the support for swinging movement relative thereto. The support is configured to raise and lower the unit relative to the floor surface, upon movement of the support relative to the vehicle, through a range of working positions in which the unit maintains a generally vertical orientation relative to the floor surface and is generally in contact therewith and a servicing position in which the unit is swung up relative to the vehicle above the floor surface to a position in which the unit is generally angled relative to the floor surface.
