KIRA B 50

Overview

The Kärcher KIRA B 50 is an autonomous scrubber-dryer robot from one of the world's most recognised commercial cleaning equipment manufacturers. Designed for continuous autonomous operation in large commercial and public spaces, the KIRA B 50 carries a 4-hour runtime, operates at 5 km/h, and holds an IPX4 water-resistance rating suitable for the wet cleaning environment. Priced at approximately $40,000, it represents a significant step up from consumer robot cleaners into the professional facility management category.

Key Specifications

• Runtime: 4 hours per charge
• Operating speed: 5 km/h
• Water resistance: IPX4
• Cleaning width: Approximately 50 cm
• Price: Approximately $40,000

The KIRA B 50 uses LiDAR-based navigation combined with a fleet management software platform, allowing facility managers to programme cleaning routes, monitor task completion, and receive alerts for low water, full dirty-water tanks, or navigation issues. It is designed to handle large, relatively open floor plans efficiently.

Use Cases

In UK commercial environments, the KIRA B 50 is suited to airport terminals, shopping centres, logistics warehouses, sports and leisure facilities, and large corporate office buildings. Facilities managers using the robot as part of a hybrid cleaning model, with autonomous robots handling large open areas overnight and human cleaners addressing detail work, washrooms, and tight spaces, report meaningful reductions in cleaning labour hours per shift.

Fleet management integration allows the KIRA B 50 to be scheduled, monitored, and reported on alongside other Kärcher equipment, which is an advantage for facilities management companies running mixed Kärcher fleets. Kärcher's UK service network provides good national coverage for maintenance and parts.

Buying Used

Used KIRA B 50 units appear through commercial cleaning equipment dealers and auction houses as early adopter facilities upgrade their fleets. Kärcher's strong service network means that used units can generally be brought back to full service specification if required. Verify that the navigation maps for the intended facility have been created or can be recreated, as route programming is facility-specific.

Alternatives to Consider

• Tennant T7AMR for a competing autonomous scrubber-dryer with BrainOS platform
• Nilfisk Liberty SC50 for a collaborative autonomous option at a lower price point
• Cleanfix RA 660 Navi for a European-made autonomous scrubber-dryer alternative
