Question

Is the difference between a burnisher and a regular floor machine (buffer) just RPM?


Answer

Yes, and the fact that each machine is used for different procedures. A standard rotary floor machine operates at 175 rpm (revolutions per minute). Some may run at higher speeds of up to 1250 rpm. A burnisher runs at 1500 to 2500 rpm (as defined in IICRC courses). The standard rotary machine at 175 rpm works side to side and has multiple uses that include, polishing, scrubbing, spray buffing, stripping, sanding (wood) or grinding/honing (stone). A burnisher is typically used for burnishing only and operates in a straight line.
