What is the Kärcher KIRA B 50 Autonomous Floor Scrubber?
The Kärcher KIRA B 50 is the right-size autonomous scrubber for medium to large hard floors. With a 750 mm vacuum working width and a 43.3 by 29.5 inch footprint, it works in warehouse offices, distribution-center break rooms, healthcare campus corridors, school cafeterias, and mid-format retail without the bulk of a ride-on machine.
Setup is intentionally simple: a large high-resolution touch display, intuitive route teaching, and no requirement for expert knowledge. The B 50 is built for unsupervised work in public spaces, with obstacle and fall detection, safety certification for public access, and an optional docking station that handles auto-fill, drain, and charging so the cleaning team can focus on higher value tasks.
RobotLAB pairs the B 50 with on-site assessment, deployment, staff training, and full nationwide service. Buy, lease, or run it as a service.

Kärcher KIRA B 50 Autonomous Floor Scrubber in detail
For warehouse and distribution
Use the B 50 for warehouse offices, break rooms, customer-facing reception areas, and mid-format DC office floors. It pairs well with the B 200 on the same campus: the B 200 handles the open production and storage areas, the B 50 keeps the office side consistent. Autonomous reporting and the calendar function let you schedule overnight or off-shift cleaning without staff supervision.
For manufacturing
Plant offices, locker rooms, break areas, and clean rooms adjacent to production all need consistent cleaning that does not interrupt the work day. The B 50 is quiet enough at 69 dB to run during occupied hours when needed, safety-certified for public access, and its cylindrical brush lifts grit and shop dust that pad-only scrubbers leave on the surface.
For big-box retail and airports
Lobbies, vestibules, food courts, restrooms-adjacent corridors, and back-of-house floors get the most foot traffic during open hours. The B 50 handles these mid-size, regular routes overnight or during off-peak, and the KIRA Robots app gives store ops audit-ready proof of clean for inspection and brand standards.
For large healthcare and education campuses
Healthcare campuses, university student unions, K-12 cafeterias and halls, and conference centers all need predictable, repeatable scrubbing on mid-size routes. The B 50 is safety-certified for public access so it can work around staff, students, patients, and visitors, with obstacle and fall detection and LED status indicators that make it obvious what the robot is doing.

About the Kärcher KIRA B 50 Autonomous Floor Scrubber.
-
What is the Kärcher KIRA B 50?
The KIRA B 50 is an autonomous floor scrubber from Kärcher designed for medium to large hard floors. It carries a 750 mm vacuum width, runs about 3.5 hours on a charge, is safety-certified for public-access environments, and fits warehouse offices, healthcare corridors, school halls, and retail. RobotLAB sells, installs, trains, and services the B 50 nationwide.
-
What spaces is the KIRA B 50 best for?
Medium to large hard or resilient floors: warehouse offices and break rooms, distribution centers, healthcare campus corridors, K-12 hallways and cafeterias, retail back-of-house, transit waiting areas, and other commercial public spaces where you want autonomous coverage in a walk-behind footprint.
-
What are the KIRA B 50's key specifications?
1,600 W rated power, 750 mm vacuum width, 1,200 rpm brush speed, 24V / 160 Ah battery, approximately 3.5 hour runtime with up to 5.2 hour charge, 69 dB sound pressure, 6 percent grade climb, 43.3 by 29.5 by 47.2 inch dimensions, 496 lb weight, safety-certified for public access, VDA 5050 communication, optional docking station.
-
How much does the KIRA B 50 cost?
RobotLAB offers the KIRA B 50 with purchase, lease, and Robots-as-a-Service (RaaS) options. For current pricing, financing terms, and lead time, request a quote and a specialist will respond the same business day.
-
Is the B 50 quiet enough to run during occupied hours?
Yes for many environments. At 69 dB sound pressure, the B 50 is comparable to normal office conversation and can run during occupied hours in warehouse offices, retail back-of-house, and similar spaces. For noise-sensitive areas such as patient rooms, classrooms, and quiet office floors, schedule it during off-peak windows.
-
How is the B 50 different from the B 200 and CV 50?
The B 50 is mid-scale: a walk-behind autonomous scrubber for medium to large hard floors. The B 200 is much larger and built for industrial-scale warehouses, manufacturing, and exhibition halls with roller-brush technology. The CV 50 is a robotic vacuum (not a scrubber) for carpet and hard floors in quieter public spaces.
