Kärcher BD 50/55 W Bp Classic Walk-Behind Floor Scrubber

The Kärcher BD 50/55 W Bp Classic Walk-Behind Floor Scrubber is a battery-powered, traction-assisted commercial floor cleaning machine designed for building service contractors, facility maintenance teams, and professional cleaning operators. Featuring a 20 in (50.8 cm) scrubbing width, 14.5 US gal (54.9 L) fresh and recovery water tanks, and a durable aluminum disc brush head and squeegee, this compact scrubber delivers efficient maintenance cleaning for public buildings, retail facilities, healthcare environments, and industrial properties. With a theoretical cleaning productivity of up to 21,500 sq ft/hr (1,997 m²/hr), integrated traction drive, and comfortable four-wheel design, it helps operators maintain large floor areas with reduced physical effort.

KEY FEATURES

• 20 IN (50.8 CM) SCRUBBING WIDTH: The BD 50/55 W Bp Classic features a 20 in (50.8 cm) disc brush working width for efficient commercial floor cleaning. This cleaning width provides a practical balance between productive coverage and maneuverability in busy facilities.
• HIGH-PRODUCTIVITY FLOOR CLEANING: With a theoretical cleaning capacity of up to 21,500 sq ft/hr (1,997 m²/hr), this scrubber is designed to handle demanding daily maintenance applications. Its combination of scrubbing performance and traction-assisted movement helps cleaning teams cover substantial floor areas efficiently.
• INTEGRATED TRACTION DRIVE: The integrated traction drive assists machine movement during operation, reducing the physical effort required to push the scrubber. This makes longer cleaning sessions more comfortable and helps operators maintain a consistent working pace.
• DURABLE ALUMINUM COMPONENTS: The disc brush head and 33.5 in (85.1 cm) squeegee are constructed from high-quality aluminum for durability in commercial cleaning environments. These robust components are designed to withstand the demands of regular professional use.
• 59 LB (26.8 KG) BRUSH CONTACT PRESSURE: The machine applies 59 lb (26.8 kg) of brush contact force to support effective removal of dirt and everyday floor contamination. This contact pressure helps the disc brush maintain consistent cleaning action across compatible hard-floor surfaces.
• 14.5 US GAL (54.9 L) DUAL WATER TANKS: Separate 14.5 US gal (54.9 L) fresh-water and wastewater tanks provide substantial capacity for routine commercial cleaning. The tank arrangement allows the machine to dispense cleaning solution and collect dirty water during scrubbing operations.
• 24 V BATTERY-POWERED OPERATION: The BD 50/55 W Bp Classic operates on a 24 V battery system with a listed runtime of up to 3 hours. Cordless operation eliminates the need to manage a power cable while cleaning and provides flexibility across large facilities.
• 180 RPM DISC BRUSH SPEED: The disc brush operates at 180 revolutions per minute to provide consistent mechanical scrubbing action. This supports regular maintenance cleaning and effective removal of surface dirt on suitable floor coverings.
• COMPACT FOUR-WHEEL DESIGN: The compact machine layout and comfortable four-wheel system provide excellent visibility of the cleaning area and strong maneuverability. Operators can navigate corridors, commercial spaces, and other maintained areas with improved control.
• EFFICIENT DIRTY-WATER RECOVERY: The 33.5 in (85.1 cm) aluminum squeegee works with the recovery system to collect dirty cleaning solution after scrubbing. Effective water recovery helps leave floors cleaner and reduces residual moisture after a cleaning pass.
• LOW OPERATING SOUND LEVEL: The scrubber has a listed sound pressure level of 65 dB(A). This makes it a practical cleaning solution for facilities where controlling operational noise is an important consideration.
• USER-FRIENDLY COMMERCIAL OPERATION: The traction drive, compact dimensions, four-wheel design, and accessible cleaning layout support straightforward daily operation. These features help reduce operator fatigue while maintaining consistent floor-cleaning productivity.

APPLICATIONS / USE CASES
