The Tennant Nobles BR-2000-DC Dust Control High-Speed Burnisher is a corded machine designed for commercial floor cleaning. It has a cleaning path of 20 inches and operates at 2000 rpm with a 1.5 HP motor. It comes with a 75-foot power cord and weighs 92 pounds. It is used but functions very well. I can send a video of it operating if desired. Any other questions, feel free to reach out!
