Abstract
An extraction head for a cleaning machine is disclosed for traveling along a cleaning path on a variable-height floor. The extraction head comprises a body including a floor-facing surface and an extraction aperture disposed in the floor-facing surface. The extraction head comprises a vacuum outlet in fluid communication with the extraction aperture. The extraction head comprises an adjustable-height brush positioned in front of the extraction head body along the cleaning path. The adjustable-height brush is configured to translocate upwardly and downwardly as the extraction head moves along the cleaning path on the variable-height floor. The adjustable-height brush may comprise a proximal end and a distal end opposite the proximal end. The proximal and distal ends may be configured to translocate upwardly and downwardly relative to each other as the extraction head moves along the cleaning path on the variable-height floor.
