Advance BU800 20B Burnisher


Superior Shine. Easy-to-Use Design.
The BU800™ 20B/20BT Battery Burnisher is a high-performance, easy-to-use floor buffer designed for polishing medium and large hard floors. With a rigid frame and nine vibration isolators, the BU800 delivers one of the smoothest burnishing experiences on the market.

Benefits of BU800 Battery Burnishers
With a double-pivot pad-driver design for a more consistent gloss, 20” polishing path and the best passive dust control on the market for superior indoor air quality, the BU800 walk-behind floor burnisher provides the most technically advanced method for restoring and maintaining a high-gloss shine on floors.

  • Simplify operation and maximize efficiency with the easy-to-use controls and self lowering burnishing deck
  • Deliver a consistent gloss with the double-pivot pad-driver design, which ensures the burnishing pad stays aligned and allows the pad to follow the floor contours
  • Take advantage of the best passive dust control on the market — a felt seal contains all dust in a specially designed shroud and directs it into a dual-port disposable filter bag
  • Ensure operator safety with the angle-activated safety switch, high mobility and superior sight lines
  • Increase runtime with dependable wet batteries or maintenance-free, longer lasting AGM gel type batteries
