New Advance BU800 20B Pad Assist Battery Burnisher
Our Take (from the SES Sales Team)
"Advance's BU800 has a smooth new design, but that's not the only thing you will notice. With improved sight lines, a shorter machine, a more rigid frame, and a double-pivot pad driver design, the BU800 is also a smooth operator available with and without traction drive. The self-regulating pad pressure helps the BU800 provide a more consistent gloss, while the self-lowering and self-raising deck offers both safety and ease of operation for the end user. The BU800 also offers passive dust control with a dust bag that is easy to access. The unit is also designed to tip back to provide easy access to pad changes. Lastly, the unit has a flexible shroud and dust seal to help capture all the dust created during the burnishing process. While new and reconditioned options are (usually) available, when you choose one of our reconditioned BU800 units, you will save both time and money. Give us a call to help you save today!"
A 20-inch battery burnisher for high-gloss floors
The Advance BU800™ 20B is a battery-powered, walk-behind floor burnisher for polishing medium and large hard floors to a high gloss. A 2.5 hp pad motor turns the 20 in pad at 2,000 rpm on the floor, and self-regulating pad pressure of up to 30 lb keeps the gloss consistent. Advance gave it a rigid frame and nine vibration isolators for a smooth ride, a self-lowering burnishing deck and passive dust control that directs dust into a disposable filter bag. The 20B is the non-traction model: the operator walks it along without a drive motor. It runs on a 36 V system of three 12 V batteries with an onboard charger.
