Kärcher BR 35/12 C Bp Walk-Behind Floor Scrubber

The Kärcher BR 35/12 C Bp Walk-Behind Floor Scrubber is a compact, lightweight battery-powered floor scrubber designed for efficient cleaning and drying of smaller commercial floor areas. Its 14 in (35.6 cm) cylindrical cleaning path, brush-assist drive, 3 gal (11.4 L) solution and recovery tanks, and cordless operation make it easy to maneuver in confined or heavily furnished spaces while eliminating the trip hazard of a power cable. Designed for shops, restaurants, gas stations, supermarkets, bathrooms, sanitary areas, and other commercial facilities, it combines powerful scrubbing with immediate solution recovery to help leave floors clean and dry after operation.

KEY FEATURES

• COMPACT 14 IN (35.6 CM) CLEANING PATH: The narrow 14 in (35.6 cm) cleaning path allows the BR 35/12 C Bp to maneuver through confined areas, narrow aisles, bathrooms, and spaces containing furniture or fixtures. Its compact dimensions make it particularly effective for smaller commercial facilities where a full-size scrubber would be difficult to operate.
• CORDLESS BATTERY-POWERED OPERATION: Battery power eliminates the need to work around an electrical cord, improving operator mobility and eliminating a potential cord-related trip hazard. The cordless design also makes the machine convenient for portable cleaning across multiple areas of a facility.
• UP TO 90 MINUTES OF ECO!EFFICIENCY RUNTIME: Standard battery operation provides up to 66 minutes of runtime, while Eco!efficiency mode extends runtime to approximately 90 minutes. The longer operating period allows users to clean more floor area between charging cycles.
• ECO!EFFICIENCY MODE: Eco!efficiency mode uses energy and resources more efficiently while extending operating time by approximately 50%. It also reduces operating noise by approximately 40%, making the machine more suitable for cleaning during business hours or in noise-sensitive environments.
• ADJUSTABLE BRUSH DOWN PRESSURE: Operators can adjust brush pressure with the turn of a knob to match different floor conditions and cleaning requirements. The system automatically increases brush speed as down pressure is increased, providing additional scrubbing action when required.
• 700–1,050 RPM BRUSH SPEED: The cylindrical brush operates between 700 and 1,050 RPM to provide effective mechanical agitation across commercial floor surfaces. Variable performance based on pressure settings allows operators to increase cleaning action when dealing with more demanding soil conditions.
• 29 LB (13.2 KG) BRUSH CONTACT PRESSURE: Up to 29 lb (13.2 kg) of brush contact pressure helps the cylindrical cleaning system provide effective floor agitation. This concentrated pressure supports thorough cleaning while maintaining the maneuverability of a compact walk-behind machine.
• BRUSH-ASSIST DRIVE: The brush-assist system helps move the scrubber forward during operation, reducing the physical effort required from the operator. This makes the machine easier to control during extended cleaning tasks without requiring a separate traction-drive system.
• 18 IN (45.7 CM) SQUEEGEE WIDTH: The 18 in (45.7 cm) suction bar collects dirty solution immediately behind the scrubber. Effective water recovery helps leave floors dry quickly after cleaning, reducing downtime and helping minimize slipping concerns in busy facilities.
• EASY SQUEEGEE MAINTENANCE: The squeegee blade is designed for straightforward removal, cleaning, and replacement. Simplified maintenance helps operators keep the recovery system performing properly without adding unnecessary service time.
• TOOL-FREE BRUSH REPLACEMENT: Brushes can be changed without tools, allowing operators to quickly select the appropriate brush stiffness or cleaning accessory for the floor surface. Faster accessory changes improve versatility and reduce downtime between different cleaning tasks.
• 3 GAL (11.4 L) SOLUTION AND RECOVERY TANKS: Separate 3 gal (11.4 L) solution and recovery tanks provide practical capacity while maintaining the machine's compact footprint. The balanced tank sizes make the scrubber well suited to smaller commercial areas and frequent daily cleaning.
• QUICK-RELEASE DIRTY WATER TANK: The recovery tank detaches easily for fast disposal of collected dirty solution. This simplifies emptying and cleaning the tank after use and helps reduce turnaround time between cleaning assignments.
• COLOR-CODED OPERATOR CONTROLS: Kärcher's color-coded control system helps operators quickly identify frequently used functions and service points. Yellow identifies daily operating controls, while light gray highlights areas associated with service and maintenance.
• ONBOARD BATTERY CHARGER: An integrated onboard charger simplifies battery charging without requiring a separate external charging station. Charging takes approximately 1–3 hours, making it easier to prepare the scrubber for its next cleaning assignment.
• LIGHTWEIGHT 77 LB (34.9 KG) DESIGN: At approximately 77 lb (34.9 kg) with batteries, the BR 35/12 C Bp is relatively lightweight for a commercial automatic floor scrubber. This makes it easier to maneuver, transport, and store in facilities where space is limited.

APPLICATIONS / USE CASES

• SMALL RETAIL STORES: The compact cleaning width makes the scrubber well suited for small shops, convenience stores, boutiques, and other retail environments. Cordless operation allows operators to maneuver around shelving, displays, and customer areas without managing a power cable.
• RESTAURANTS AND FOOD SERVICE AREAS: The machine provides mechanical scrubbing and immediate solution recovery for applicable hard floors in restaurants and food-service environments. Its compact dimensions help operators navigate around tables, counters, equipment, and other obstacles.
• GAS STATIONS AND CONVENIENCE STORES: Portable battery operation and a narrow cleaning path make the BR 35/12 C Bp practical for smaller, high-traffic facilities. Operators can quickly clean floor areas without repeatedly relocating electrical cords between outlets.
• SUPERMARKETS: The compact scrubber can be used for smaller supermarket sections, checkout areas, aisles, service areas, and other spaces where maneuverability is important. Eco!efficiency mode also provides quieter operation for cleaning during occupied periods.
• BATHROOMS AND SANITARY AREAS: Its compact size allows the machine to access many areas where larger automatic scrubbers cannot operate effectively. The combination of cylindrical scrubbing and solution recovery helps streamline routine hard-floor maintenance.
• NOISE-SENSITIVE FACILITIES: Eco!efficiency operation reduces noise from approximately 66 dBA to 62 dBA. This makes the machine useful for daytime cleaning and environments where minimizing operational noise is important.
• DELICATE HARD FLOORS: Compatible soft brushes and microfiber accessories allow the scrubber to be configured for daily maintenance of appropriate delicate surfaces, including LVT and stone tile. Selecting the correct brush or pad helps operators match cleaning action to the floor surface.
