Product Description
Karcher High-Speed Floor Burnishing
20-inch commercial floor burnisher available in 1,500 RPM and 2,000 RPM configurations with a 1.5 HP motor, 75-foot cord, and cast-aluminum base.
The Karcher BDP 51 C is a commercial 20-inch cord-electric floor burnisher available in 1,500 RPM and 2,000 RPM configurations. Both models are designed to restore and maintain gloss on finished hard floors while providing durable construction, smooth operator control, and productive performance for commercial floor-care programs.
The 1,500 RPM configuration is a strong choice for routine gloss maintenance in schools, healthcare facilities, offices, and institutional buildings. The 2,000 RPM configuration is designed for facilities seeking a higher-gloss or wet-look appearance in retail stores, airports, showrooms, and other high-visibility environments.
Both configurations feature a 20-inch burnishing path, a 1.5 HP motor, a 75-foot power cord, a floating handle system, a durable cast-aluminum base, and safety features designed for professional commercial use.
