New Viper Venom 20DS 20" Dual-Speed Buffer
Buffers vs Burnishers: Which One Do I Need?
The Viper Venom 20 Dual-Speed Buffer (VN20DS) is a powerhouse floor machine built for facilities that demand reliability, versatility, and long-term durability. Its all-metal housing and steel triple-planetary gearbox are engineered to stand up to the rigors of high-demand environments, delivering consistent performance year after year. The dual-speed motor offers true flexibility across a range of applications — 185 RPM for heavy-duty scrubbing and stripping, and 330 RPM for polishing and high-gloss finishing. A 1.5 HP DC-rectified motor and a 50-foot safety-yellow power cord round out the package, pairing raw cleaning power with practical safety features.
This machine is purpose-built to handle virtually any floor care task — scrubbing, stripping, polishing, bonnet carpet cleaning, and beyond — across settings as varied as classrooms, kitchens, gym floors, and healthcare facilities. Weighing in at just under 100 pounds, the VN20DS is substantial enough to power through tough jobs while remaining easy to control and maneuver. It also operates at a low 65–68 dB(A), keeping noise levels manageable in occupied spaces. Backed by a 3-year warranty covering parts, motor, and gearbox along with extended labor coverage, the Viper Venom 20 Dual-Speed Buffer is a sound, long-term investment for any facility looking for one machine that can do it all.
