ABSTRACT:
A deflooding tool for vacuum removal of liquid such as water or the like from carpets, rugs or other floor coverings. Preferably the tool comprises a rigid, hollow generally cubicle vacuum chamber disposed substantially vertically with respect to the flooded carpet. The vacuum chamber includes a lower, open suction inlet for intaking liquids to be removed, and vacuum is supplied to the chamber by an elongated, rigid, tubular handle angularly coupled at one end to the top rear of the vacuum chamber. The remote end of the handle terminates in a connection to a conventional vacuum source. Wheels are rigidly mounted at the bottom rear of the vacuum chamber for facilitating the tool. A generally cylindrical, rigid heavy roller is mounted at the bottom front of the vacuum chamber for compressing the carpet, rug or other floor covering to liberate liquids to be captured through the vacuum inlet. Preferably the ratio of the wheel diameter to the roller diameter is 10:7. A rigid weight box is secured in spaced-apart relation relative to vacuum chamber and is vertically spaced-apart and substantially vertically aligned with the center of rotation of the roller. Because of the operative moments established by the centers of mass of the various portions of the tool, a mechanical advantage is experienced by the operator when the handle of the tool is either lifted or depressed during operation.
