Eliminate follow-up dust mopping of burnishing dust from floors. The specially designed shroud on the Kent SelectGloss^™ 20B battery-powered burnisher confines dust, which is blown into dual filter/collector bags. The free-floating 20 inch (51 cm) flexible pad follows uneven floors, giving them an even shine. Pad speed is 2,500 rpm with no load, but the SelectGloss 20B has an adjustment for the right weight-to-speed combination, ensuring the best burnishing results.
