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.

Abstract: A portable HEPA filter chamber is provided with a pair of wheels and a handle whereby it can be moved by a person in the manner of a two-wheeled hand-truck. One or more inlet openings receive air from an area to be cleaned, dried, or decontaminated. An air outlet is adaptable to the air inlet height of standard, widely-used carpet dryer blowers. Pre-filters are provided in the portable chamber upstream of the HEPA filter. Strapping holds the blower unit to the outlet of the filter chamber. Support wheels and a handle enable convenient hand-truck type operation to facilitate movement of the combination when and as needed in the area being dried. An upstanding perimeter flange, and the handle, when retracted, serve as a fence to stabilize multiple chambers, when stacked for storage or transportation in a truck. The exterior wall of the chamber is shaped for inter-fitting with others to minimize floor space for storage and transporting.

Abstract: The flooding device is disclosed coupled to a suction pump truck by flexible conduit. The deflooding device includes a suction chamber having a downward facing opening therein and a compression element, namely a roller, protruding therefrom. The roller has openings or other structure to allow water to exist beneath the roller while the roller is compressing the carpet nap. A propulsion system including a motor drive system attached to the roller allows the unit to be self-propelled across the carpet.
