chamber 16d through dispensing tube 86d through aperture 110 and into dispensing tube 34 it will be appreciated that the internal cylindrical unit 108 could be rotated to similarly match up with any of the other dispensing tubes such as 86a and 86c thus it will be appreciated that any of the fluids contained in the dispensing chambers may be selected however it is often the case that no fluid is desired or in the event it is desirable to use dispensing tube 34 as a suction tube 34 the internal cylindrical unit 108 may be rotated to a position such as is shown in fig8 so that all of the dispensing chambers are cut off from dispensing tube 34 thus it will be appreciated that in operation of the present apparatus the machine operator may select by selection levers 112 and 114 shown in fig1 any one of the dispensing chambers 16a through 16d at the same time valve 90 will be open so that as power source 26 operates reciprocating action will be applied to brushes 20 and a vacuum will be applied to suction tube 38 thus it will be appreciated that the selected fluid such as for example a cleansing or stripping fluid will flow down through the dispensing tube 34 onto the floor being treated so that as the floor is scrubbed with scrub brush 20 the floor will be cleaned as the unit is moved forward the excess liquid will be drawn off and up through suction tube 38 and into receiving chamber 18 it will then be possible to select a second chamber which may for example contain nothing more than rinse water the machine is again moved over the floor thereby rinsing the floor of the cleaning fluid and sucking the excess.
