Abstract
A floor machine comprising a motor, a body, and a dust collection system. The dust collection system comprises a skirt, which is coupled to the floor machine and forms a cavity over the body and a floor treatment pad. The skirt includes an air channel device secured to a bottom edge of the skirt. The air channel device encircles the floor treatment pad and comprises a multiplicity of slots between a floor and the skirt. Jointly, the skirt and air channel device confine particles within the cavity. A vacuum for sucking the particles from the cavity creates high velocity air flow through the air channel device. Negative pressure within the cavity prevents particles from escaping. The particles are removed from the cavity through a vacuum tube into the vacuum.
