Abstract: A turbine wheel in the cavity of a turbine housing is driven by liquid, ordinarily water, introduced into the housing through a conduit which can draw the liquid from a reservoir. The turbine wheel is rotatable on a shaft which is attached to the housing and extends downward through the housing to a position below the housing where a brush is rotatable on the shaft. The brush is driven by the turbine through an arrangement of gears. Openings through the turbine housing are positioned to permit the water passing through the housing to flow downward in a 360.degree. circle around the exterior of the brush. The turbine functions as an air pump drawing air into the housing which aids in forcing the water out the exit openings so that less water volume and pressure is required to force the water out in the 360.degree. circle than would otherwise be necessary.
