Burnisher grade floor machines typically spin the paddriver over 1,000 rpms and require a special unit that is bolted onto the floor machine, unlike standard 175 rpms buffers that use a twist lock "clutch plate" mounting system.
Due to the very high rpms of typical burnishers, brushes can not be installed.
