ABSTRACT:
A hand-held tool with a rotary pumice or suitable synthetic grinding wheel is connected by means of a flexible drive cable to a remote water turbine contained in a floating housing and is used to remove calcium deposits from decorative tile around a periphery of a swimming pool. The outlet of the water turbine is connected to one end of a suction hose, the other end of which is connected to a suction inlet of an electric pump/filter unit, causing water to be drawn from the swimming pool through the turbine. In an alternate embodiment of the invention, the remote turbine is placed in a lavatory sink. Water from a faucet is forced through the turbine, causing rotation of the drive cable, so that the hand tool can be used to clean calcium deposits from bathroom facilities.
