Kärcher BR 45/22 C BP Compact Walk-Behind Floor Scrubber

The Kärcher BR 45/22 C Bp Compact Walk-Behind Floor Scrubber is a battery-powered commercial scrubber dryer designed for efficiently cleaning large floor areas while maintaining exceptional maneuverability in narrow and hard-to-reach spaces. Its 18 in (45.7 cm) cleaning path, steerable roller-brush deck with Kärcher Advanced Response Technology (KART), built-in pre-sweeping, and maintenance-free lithium-ion battery system make it ideal for professional cleaners and facility maintenance teams working in retail, healthcare, education, hospitality, institutional, and other commercial environments. The scrub deck rotates up to 200 degrees in both directions, keeping the brush and squeegee positioned transverse to the direction of travel for consistent cleaning and recovery while navigating corners and confined areas.

KEY FEATURES

• 18 IN (45.7 CM) CLEANING PATH: The 18 in (45.7 cm) working width provides an effective balance between commercial cleaning productivity and compact maneuverability. Operators can efficiently cover larger areas while still navigating narrow aisles, congested spaces, and other difficult-to-reach locations.
• INNOVATIVE STEERABLE SCRUB DECK: The steerable roller-brush deck provides excellent maneuverability and allows the machine to follow the operator naturally through turns and confined spaces. This helps reduce operator effort while making detailed cleaning around obstacles easier and more efficient.
• 200-DEGREE KART STEERING TECHNOLOGY: Kärcher Advanced Response Technology (KART) allows the scrub deck to rotate up to 200 degrees in both directions. The brush and squeegee remain continuously transverse to the direction of travel, supporting uniform cleaning and effective dirty-water recovery even while maneuvering.
• HIGH-PERFORMANCE LITHIUM-ION BATTERY: Built-in maintenance-free lithium-ion batteries provide long operating life and convenient cordless cleaning. The battery system is designed to provide a service life up to three times longer than conventional lead batteries while supporting opportunity charging between cleaning assignments.
• OPPORTUNITY CHARGING: Lithium-ion battery technology allows the machine to be charged during available breaks or periods of downtime. This gives cleaning crews greater flexibility to keep the scrubber available throughout demanding work schedules.
• ON-BOARD BATTERY CHARGER: The integrated charger allows the scrubber to be charged wherever a suitable electrical connection is available. Eliminating the need to transport a separate charger makes day-to-day battery management easier.
• ECO!EFFICIENCY MODE: Eco!efficiency mode conserves energy and resources while extending available operating time. It also reduces machine noise by approximately 40%, making the scrubber more suitable for daytime cleaning and occupied facilities.
• QUIET 62 DBA ECO! OPERATION: Operating noise is rated at 66 dBA in standard mode and 62 dBA in eco! mode. Reduced sound levels help cleaning teams work in noise-sensitive environments with less disruption to occupants and customers.
• BUILT-IN PRE-SWEEPING: An integrated pre-sweeping function helps collect loose debris before the primary scrubbing process. Combining debris collection and wet scrubbing can reduce preparation work and improve overall cleaning productivity.
• 38 LB (17.2 KG) DOWN PRESSURE: The cylindrical brush applies 38 lb (17.2 kg) of down pressure for effective mechanical cleaning. Combined with brush speeds ranging from 750 to 1,050 RPM, this provides strong scrubbing action for demanding commercial floor-maintenance applications.
• HIGH-SPEED CYLINDRICAL BRUSH: The roller brush operates between 750 and 1,050 RPM to provide effective mechanical agitation across the floor surface. Different optional brush configurations allow the cleaning action to be adapted to smooth, textured, grouted, irregular, delicate, or rugged floors.
• 6 GAL (22.7 L) SOLUTION AND RECOVERY TANKS: Separate 6 gal (22.7 L) solution and recovery tanks provide useful capacity for commercial cleaning assignments while maintaining the machine's compact footprint. This balance helps operators clean efficiently without making the scrubber unnecessarily bulky.
• 20 IN (50.8 CM) SQUEEGEE WIDTH: The 20 in (50.8 cm) recovery width extends beyond the 18 in (45.7 cm) cleaning path to collect dirty solution effectively. Its relationship with the steerable scrub deck helps maintain water pickup while the machine changes direction.
• COLOR-CODED CONTROLS: Clearly identified controls simplify operation and reduce the amount of training required for new users. This operator-friendly design is particularly useful in facilities where multiple employees may use the same scrubber.
• EASY DIRTY-WATER DISPOSAL: A dedicated dirty-water drain hose simplifies emptying the recovery tank after cleaning. Easier tank disposal reduces handling effort and helps operators complete post-cleaning maintenance more efficiently.
• OPTIONAL HEPA FILTRATION: An optional HEPA filter can filter exhaust air from the dirty-water system. This provides an additional configuration option for hygiene-sensitive environments where controlling exhaust-air particulates is important.
• UP TO 19,375 SQ FT/HR (1,800 M²/HR) THEORETICAL PRODUCTIVITY: The machine provides practical productivity of approximately 13,560 sq ft/hr (1,260 m²/hr) and theoretical productivity of approximately 19,375 sq ft/hr (1,800 m²/hr). This makes the compact scrubber capable of handling substantial commercial cleaning workloads.

APPLICATIONS / USE CASES

• COMMERCIAL FLOOR CLEANING: The 18 in (45.7 cm) cleaning path and high-speed cylindrical brush provide productive daily cleaning for compatible commercial hard floors. Its compact dimensions allow it to work efficiently in facilities where larger scrubbers may be difficult to maneuver.
• NARROW AND CONGESTED AREAS: The 200-degree steerable scrub deck makes the BR 45/22 C Bp particularly effective in narrow aisles, around displays, between fixtures, and near other obstacles. Operators can change direction smoothly while maintaining the orientation of the cleaning and recovery system.
• RETAIL FACILITIES: Quiet battery-powered operation, excellent maneuverability, and high productivity make the scrubber suitable for supermarkets, retail stores, shopping facilities, and similar environments. Eco!efficiency mode can further reduce noise when cleaning during operating hours.
• HEALTHCARE AND HYGIENE-SENSITIVE AREAS: Cordless operation and an available HEPA filtration option make the machine suitable for appropriate hygiene-sensitive environments. The optional HEPA system filters exhaust air from the dirty-water system for additional air-management capability.
• EDUCATIONAL AND INSTITUTIONAL FACILITIES: The compact machine can clean hallways, classrooms, common areas, cafeterias, and other compatible hard-floor spaces. Color-coded controls simplify operation where multiple maintenance personnel may share equipment.
• DELICATE FLOOR MAINTENANCE: An optional cylindrical microfiber pad is available for daily cleaning of delicate surfaces, including LVT and stone tile. This allows operators to configure the scrubber for gentler maintenance of sensitive flooring.
• TEXTURED AND GROUTED FLOORS: Specialized cylindrical brushes are available for textured, grouted, irregular, and rugged floor surfaces. Selecting the appropriate brush allows the same machine to address different commercial floor conditions.
• DAYTIME CLEANING: Eco!efficiency mode reduces operating noise to approximately 62 dBA while conserving energy. This makes the scrubber particularly useful when cleaning must be performed around employees, customers, students, patients, or other building occupants.
