摘要：
In combination, a removable tool may be selectively attached to the cleaning wand of a carpet extractor to alternatively clean hard surfaced floors, such as grouted tile and when not attached, clean carpeted floors. The removable tool may be sold as an aftermarket item for existing carpet extractors. A method of using the carpet extractor with the removable tool allows the apparatus to fulfill dual purposes, e.g., cleaning hard surfaced floors and when the tool is attached to the cleaning wand, and when the tool is removed from the wand to clean carpeted floors.
