Product Description
20" Ride-On Floor Scrubber Pad Driver Wet Batteries Karcher BD 50/70 R Bp
The Karcher BD 50/70 R Bp is a compact rider automatic floor scrubber designed for facilities that need the productivity of a ride-on machine with the maneuverability of a walk-behind scrubber. This model features a 20 inch pad driver system with traditional wet batteries, making it an excellent solution for schools, universities, government buildings, healthcare facilities, and commercial properties with tight hallways or congested cleaning areas.
Many facilities choose this model because it delivers ride-on productivity at a price point similar to many walk-behind floor scrubbers. Operators can clean significantly larger areas while reducing labor time and operator fatigue.
Because of its slim 52 inch machine length and narrow turning radius, the BD 50/70 R Bp can easily navigate hallways, classrooms, restrooms, and other confined spaces while still providing ride-on productivity.

Why choose the BD 50/70 R Bp instead of a walk-behind scrubber?
