发明名称 Systems and methods for extracting liquid from floor coverings
摘要 An extractor tool for extracting invasive fluid from a floor covering defining a floor surface. The extractor tool comprises a frame assembly, an extraction head, and a drive roller. The frame assembly defines a support surface. The extraction head is mounted to the frame assembly and defines an extraction opening that engages the floor surface. The drive roller assembly is mounted to the frame assembly and also engages the floor surface. A user stands on the support surface between the extraction head and the drive roller assembly such that the user's weight is transferred to the floor surface through the extraction head and the driver roller assembly. The user operates the driver roller assembly to propel the extractor tool along the floor surface.
