Abstract
An automatic floor scrubber and buffer is described. This invention provides for simultaneous scrubbing and buffing of floors through the use of a plurality of pads operating at different speeds to optimize the scrubbing and buffing operation of the device. This invention also provides for the application of cleaning solution and the means of removing, collecting and storing the resulting dirty water and cleaning solution prior to the application of the buffers. Moreover, this invention provides the means for easily pivoting the scrubbing and buffing pads, thereby removing them from contact with the floor for transportation, removal or replacement. Also, this invention provides a propane powered drive motor thereby providing improved service life as well as permitting use where electricity is not readily available. In sum, this invention addresses the problem of floor cleaning and polishing and does so by eliminating the need for going over the same floor twice, once to scrub and once to buff, thereby saving the user time as well as eliminating the need for two separate machines.
