Abstract:
A method of extracting fluid from a floor surface comprising the steps of:a) providing an extraction tool having a frame assembly defining a support surface; b) mounting an extraction head to the frame assembly, wherein the extraction head includes an extraction opening that engages with the floor surface; c) mounting a drive roller assembly to the frame assembly, wherein the drive roller assembly engages the floor surface; d) standing on the support surface between the extraction head and the drive roller assembly such that the weight of the user on the support surface is transferred to the extraction head or the drive roller assembly; e) operating the drive roller assembly to propel the extraction tool along the floor surface; f) extracting fluid from the floor surface through the extraction opening; and g) controlling the speed of the extraction tool across the floor surface by shifting the user's weight on the support surface such that movement of the user's weight towards the extraction head increases friction between the floor surface and the extraction head resulting in a decrease in speed of the extraction tool and movement of the user's weight towards the drive roller assembly results in an increase in speed of the extraction tool across the floor surface.
