Abstract
A deflooding device includes a suction chamber having a downward facing opening therein and a compression roller protruding downward therefrom. The roller has openings or other structure to allow water to exist beneath and inside the roller while the roller is compressing the carpet nap. A propulsion motor drive system coupled to the roller allows the unit to be self-propelled and driven at variable speeds in forward and reverse across the carpet. Operator weight standing or sitting on the device, with or without ballast or discrete additional weight applies compression of roller on carpet. Coupling from suction chamber to on-board, adjacent, or remote vacuum source is convenient.

A device for deflooding liquid from carpet, comprising:
- a housing;
- a suction conduit with a discharge end and an intake end, said discharge end being couplable with a suction source for suction of the liquid through said conduit;
- an enclosed suction chamber at said housing and coupled to said intake end of said suction conduit, said suction chamber having a downward facing opening;
- a roller located within said housing and rotatable around a horizontal axis of rotation, said roller partially protruding below the level of the bottom of said downward facing opening, with said horizontal axis of rotation positioned at a level above the first-mentioned level and, wherein said roller compresses the carpet with substantial downward force to press liquid from the carpet;
- and
- a drive motor coupled to said roller to drive the roller across the carpet.
