Carpet Extractor

A floor care apparatus is disclosed wherein a powered brush assembly 20 having a multiplicity of rotary brushes 25, supported by a beam 22, is suspended within the apparatus such that the brush assembly 20 floats freely upon the surface being cleaned without supporting any of the machine's weight. A gravity feed fluid supply drips cleaning solution into open top troughs 71 within the support beam 22, one above each brush 25, which then filters through conduits 74 in the beam 22 to the associated rotary brush 25. The rotary brushes 25 are generally configured as spur gears and function in a gear train wherein one brush drives all the other gear brushes. A pair of air driven turbines 125 are disclosed, one for driving the floor scrubbing brushes 25 and one for driving the cleaning solution supply pump 130. A unique linkage mechanism 150 is taught whereby only one turbine or the other is energised depending upon whether the operator selects the floor cleaning mode an above floor cleaning mode.
