The Kärcher KIRA B 50 is an advanced autonomous floor scrubber dryer designed to transform the way commercial floor cleaning is carried out. Combining Kärcher's proven scrubber dryer technology with intelligent robotic navigation, the KIRA B 50 delivers consistent, high-quality cleaning across medium to large floor areas while allowing cleaning staff to focus on higher-value tasks.
Ideal for retail stores, healthcare facilities, airports, schools, logistics centres, office buildings, industrial sites, and public buildings, the KIRA B 50 offers an efficient and reliable solution for businesses looking to improve productivity, reduce labour-intensive tasks, and maintain consistently high cleaning standards.
The Kärcher KIRA B 50 is designed to clean independently with minimal operator intervention. Once cleaning routes have been configured using the intuitive touchscreen interface, the robot navigates autonomously throughout the designated area, delivering reliable and repeatable cleaning performance every time.
For businesses requiring maximum automation, the optional docking station enables fully autonomous operation by automatically recharging the battery, refilling the fresh water tank, emptying dirty water, and rinsing the recovery tank, allowing the machine to complete scheduled cleaning programmes with very little manual input.
Equipped with a sophisticated multi-sensor navigation system, including laser scanners, 3D sensors, ultrasonic sensors, and intelligent obstacle detection software, the KIRA B 50 safely operates in busy commercial environments.
The robot continuously monitors its surroundings, automatically detecting people, furniture, temporary obstacles, glass panels, and other objects. It adjusts its route in real time to avoid collisions while maintaining efficient cleaning performance, making it suitable for use even in public and occupied spaces. Safety-certified operation provides additional confidence in environments where staff and visitors are present.
Built on Kärcher's trusted scrubber dryer platform, the KIRA B 50 delivers excellent cleaning performance with every pass. Its roller brush system simultaneously pre-sweeps and scrubs the floor, removing loose debris before deep cleaning the surface.
An integrated side brush extends cleaning right up to edges and skirting boards, reducing the need for manual finishing work while improving overall productivity. Water consumption, detergent dosing, and cleaning speed can all be precisely controlled to achieve outstanding cleaning results while minimising operating costs.
The KIRA B 50 offers the flexibility to operate either autonomously or manually, allowing businesses to adapt the machine to changing cleaning requirements. It can perform scheduled autonomous cleaning during quieter periods while also functioning as a conventional scrubber dryer whenever manual operation is preferred.
This versatility makes the KIRA B 50 an excellent investment for facilities with varied layouts, changing workloads, or areas requiring occasional manual intervention.
Cleaning performance can be monitored through Kärcher's cloud-based web portal, providing detailed cleaning reports, machine status updates, and operational data. Mobile notifications keep operators informed of cleaning progress, allowing managers to monitor machine performance remotely and optimise cleaning schedules with confidence.
Labour shortages and increasing cleaning demands make automation more valuable than ever. The Kärcher KIRA B 50 works alongside cleaning teams by taking over repetitive floor cleaning tasks, allowing staff to concentrate on detailed cleaning, sanitisation, and other specialist duties.
By delivering predictable cleaning performance, efficient resource management, and reduced manual labour, the KIRA B 50 helps businesses improve operational efficiency while maintaining consistently high cleaning standards.
The Kärcher KIRA B 50 is ideal for:
Its combination of autonomous operation, intelligent navigation, and professional scrubbing performance makes it one of the most advanced floor cleaning solutions available for modern commercial environments.
The Kärcher KIRA B 50 represents the future of commercial floor cleaning. Combining autonomous robotic technology with Kärcher's proven scrubber dryer performance, it delivers exceptional cleaning quality while reducing labour requirements and increasing operational efficiency.
With intelligent navigation, advanced safety systems, optional fully autonomous docking, cloud-based fleet management, and outstanding cleaning performance, the KIRA B 50 is the ideal solution for organisations looking to modernise their cleaning operations and achieve consistently excellent results with minimal manual intervention.
