B 50 W Bp ORB + O51 + AGM

Commercial-Grade Orbital Floor Cleaning With AGM Battery Power

The Kärcher B 50 W Bp ORB + O51 + AGM is a professional battery-powered walk-behind floor scrubber engineered for businesses that need serious cleaning performance, excellent maneuverability, and consistent water recovery without stepping up to a large ride-on machine.

Equipped with Kärcher's 20-inch O51 orbital brush head, maintenance-friendly AGM battery system, powered traction drive, and 33.4-inch vacuum working width, the B 50 W delivers the productivity commercial and industrial facilities need while maintaining a compact footprint that's easy to maneuver through aisles, doorways, and congested work areas.

With a practical cleaning capacity of up to 19,805 sq. ft. per hour, this configuration is an excellent choice for warehouses, retail stores, schools, healthcare facilities, commercial buildings, parking facilities, dealerships, manufacturing facilities, municipal buildings, and professional cleaning contractors.

Why Choose the B 50 W ORB?

Unlike conventional floor scrubbers that rely solely on a rotating disc, the O51 orbital cleaning head provides intensive mechanical floor agitation while helping reduce water consumption.

The orbital system is particularly useful when cleaning heavily textured, uneven, or difficult commercial flooring where effective agitation is critical.

Combined with up to 79.3 lb of brush contact pressure, the B 50 W ORB gives operators the cleaning power needed for demanding floor maintenance applications.

Built for Productivity

The B 50 W combines a 20.07-inch cleaning path with a 33.4-inch vacuum working width and powered traction drive.

The result is a machine capable of cleaning up to:

19,805 sq. ft./hr practical working capacity
32,938 sq. ft./hr theoretical working capacity

Its compact design and 55.1-inch aisle turning width make it particularly effective in facilities where a larger ride-on scrubber would be cumbersome.

AGM Battery Configuration

This B 50 W configuration is equipped with a low-maintenance AGM battery system and onboard charger, eliminating many of the routine maintenance requirements associated with traditional flooded lead-acid batteries.

Simply plug the machine into an appropriate power source when charging is required.

For commercial operators managing multiple employees, locations, or machines, AGM technology can also simplify fleet maintenance because operators do not need to routinely check and refill battery water.

Note: The AGM battery version of this machine is not available in California.

Kärcher Intelligent Key System – KIK

The Kärcher Intelligent Key System (KIK) allows managers to control how the machine is operated instead of relying entirely on individual operator settings.

The system supports more than 30 user languages and customizable user permissions, helping organizations standardize machine operation across different employees and shifts.

This is particularly valuable for:

• Contract cleaning companies
• Schools and universities
• Municipal facilities
• Warehouses and distribution centers
• Healthcare environments
• Large commercial properties
• Facilities with multiple machine operators

Machine Connect App Compatibility

Take greater control over equipment management with Kärcher's Machine Connect app.

Operators and facility managers can use connected functionality to adjust settings and monitor machine performance remotely, helping modernize floor-care operations and improve equipment oversight.

Excellent Water Recovery

Cleaning the floor is only half the job—the machine also needs to leave it ready for use.

The B 50 W features a robust die-cast aluminum suction bar with premium Linatex® suction lips and a 33.4-inch vacuum working width designed for effective dirty-water recovery.

Better water recovery means cleaner, drier floors and less residual water left behind after scrubbing, an important consideration in busy commercial environments.

13.2-Gallon Dual-Tank System

Separate 13.2-gallon fresh-water and 13.2-gallon recovery tanks keep clean solution and recovered wastewater isolated throughout the cleaning process.

The machine also features auto-rinse capability, while an optional auto-fill system can further streamline daily maintenance and preparation.

Quiet 65 dB(A) Operation

At only 65 dB(A), the B 50 W is well suited to environments where excessive equipment noise can be disruptive.

This makes it an attractive commercial floor scrubber for applications such as retail stores, healthcare facilities, schools, offices, hotels, and occupied commercial buildings.

Operator-Friendly Design

Kärcher designed the B 50 W around straightforward daily operation.

The machine incorporates an Easy Operation selector switch, Kärcher color-coded operating concept, adjustable ergonomic controls, powered traction drive, and Home Base attachment points for carrying items such as mops and other manual cleaning accessories.

The traction motor helps propel the machine at speeds up to 3.7 mph, reducing the effort required from the operator during longer cleaning shifts.
