A portable extractor according to the teachings of the present invention is taught including a tool assembly pivotally mounted on a main body assembly. The portable extractor is supported on the floor by a set of wheels on the tool assembly and by a set of wheels on the main body assembly. The tool assembly applies a cleaning solution to the floor, with the cleaning solution being drawn from a supply tank of the main body assembly. The tool assembly also extracts the cleaning solution from the floor, with the extracted cleaning solution being deposited in a storage tank of the main body assembly. In a preferred form for cleaning carpeted floors, the tool assembly further includes a powered rotary brush for agitating the carpet. In operation, the tool assembly pivots with respect to the main body assembly between working and transport modes automatically when the portable extractor is pulled or pushed on the floor. In the working mode, the tool assembly is located such that the cleaning process members engage the floor and in the transport mode, the tool assembly is carried by its wheels and the cleaning process members are spaced from the floor. In the most preferred form, the supply tank is in a novel saddle type arrangement on the storage tank to maintain substantially uniform weight distribution on the wheels of the tool assembly when the levels in the tanks change. |
