OVERVIEW

The Kärcher KIRA B 50 is an autonomous scrubber-drier designed to relieve professional cleaning teams in medium-to-large indoor hard-floor environments including retail, healthcare, transport, public buildings and industry.

Its roller-brush system pre-sweeps and scrubs in one pass, with a 550 mm brush width, 750 mm vacuum width, integrated side brush and 55 L fresh- and dirty-water tanks.

Kärcher publishes autonomous theoretical area performance up to 2,365 m²/h, approximately 3.5 hours of battery runtime and autonomous speed up to 4.3 km/h.

High-performance 360-degree sensing, public-area safety certification, Teach & Repeat and Smart Fill route creation, web-based reporting and an optional docking station make KIRA B 50 a mature platform for repeatable autonomous floor cleaning.

FAQ

Frequently asked questions

How much does the Kärcher KIRA B 50 cost? +

Kärcher does not publish one universal worldwide retail price for the KIRA B 50. Commercial pricing depends on country, docking station, service agreement, delivery, commissioning, training and warranty.

You can request a Kärcher KIRA B 50 quote through Anton Robots and compare the full deployed package.

Where can I buy the Kärcher KIRA B 50? +

You can request the Kärcher KIRA B 50 through Anton Robots, Kärcher Professional and authorised regional Kärcher channels.

Confirm whether the quote includes the docking station, batteries and charger, commissioning, route setup, detergent system, training, warranty and local field service.

Where can I find a Kärcher KIRA B 50 for sale? +

KIRA B 50 is a current Kärcher Professional cleaning robot and is normally supplied through professional sales rather than consumer-style checkout.

If evaluating an ex-demo or used unit, verify battery condition, software access, service history, sensors, brushes, squeegee and whether Kärcher support transfers.

Can I get a quote or demonstration for the Kärcher KIRA B 50? +

Yes. Kärcher Professional provides commercial sales support, and you can request a KIRA B 50 quote through Anton Robots.

Provide floor area, route widths, floor finish, traffic, operating hours, water and drainage access and destination country so the supplier can validate the deployment.

What is included when you buy the Kärcher KIRA B 50? +

Kärcher’s current scope of supply includes the battery and charger, squeegee, two roller brushes, side brush and warning beacon. The machine also includes autonomous cleaning hardware and its main software functions.

  • KIRA B 50 robot
  • Two 24 V / 160 Ah lithium-ion batteries
  • Battery charger
  • Squeegee, two roller brushes and side brush
  • Autonomous route and reporting functions
  • Optional docking station
  • Deployment, training and service according to the regional offer
How productive is the Kärcher KIRA B 50? +

Kärcher publishes a maximum theoretical autonomous area performance of 2,365 m²/h and approximately 1,830 m² of coverage per tank filling.

Real productivity depends on traffic, route layout, soil level, speed, detergent settings, water use and obstacle frequency.

How long does the Kärcher KIRA B 50 run and charge? +

KIRA B 50 is specified for approximately 3.5 hours of battery runtime. Maximum charging time is listed at about 5.2 hours.

The robot uses two 24 V / 160 Ah lithium-ion batteries. Actual runtime varies with cleaning conditions and battery age.

How fast does the Kärcher KIRA B 50 move? +

Kärcher publishes a maximum autonomous speed of approximately 4.3 km/h.

Cleaning speed can be adjusted according to route, traffic and floor conditions. Maximum travel speed should not be treated as guaranteed cleaning productivity.

How narrow a route can the KIRA B 50 navigate? +

Kärcher lists a minimum autonomous clearance width of approximately 0.9 m and an autonomous aisle turning width of about 1.5 m.

Real routes should be measured with shelving, furniture, doors and pedestrian traffic in place before deployment.

How does the Kärcher KIRA B 50 navigate safely? +

KIRA B 50 uses high-performance sensors with 360-degree environment detection and lateral monitoring to avoid collisions, falls, people and obstacles.

Kärcher states that the robot is safety-certified in accordance with IEC 63327 for operation in public areas.

What are Teach & Repeat and Smart Fill on the KIRA B 50? +

Teach & Repeat allows an operator to manually teach precise routes, which is useful in narrow or constrained spaces. Smart Fill lets the robot plan cleaning coverage autonomously inside larger defined open areas.

Routes can later be edited with no-go zones, speed filters, no-clean zones, horn zones and interaction zones.

What does the KIRA B 50 docking station automate? +

The optional docking station enables highly autonomous operation by handling fresh-water refill, dirty-water drainage, tank rinsing and battery charging.

The robot can also operate without the docking station. Sites using the dock need suitable power, water, drainage and installation space.

What cleaning and reporting data does KIRA B 50 provide? +

KIRA B 50 connects to Kärcher Equipment Management for remote status information, cleaning reports, notifications and device monitoring.

The platform can send status messages to mobile devices and supports scheduled cleaning. Confirm connectivity, account ownership and any regional software terms during procurement.

Where is the Kärcher KIRA B 50 a good fit? +

Kärcher positions KIRA B 50 for medium-to-large hard or resilient floor areas, including retail, healthcare, public facilities, transport, industrial sites and building-cleaning operations.

It can work in open spaces and more constrained environments provided the autonomous clearance requirements are met.

Can the Kärcher KIRA B 50 be deployed internationally? +

Kärcher Professional has a broad international sales and service network, but KIRA B 50 availability, configuration, certification and docking support vary by market.

Before importing, confirm electrical supply, battery shipping, detergent compatibility, software region, spare parts and the local service organisation.

Is the Kärcher KIRA B 50 worth buying? +

KIRA B 50 is worth considering for organisations that want a mature autonomous scrubber-drier backed by an established professional cleaning network. Its safety certification, 55 L tanks, pre-sweeping system, route tools and optional full-service dock are strong advantages.

It is a weaker fit for carpet-heavy sites, outdoor cleaning or routes below its autonomous clearance. Compare it with other commercial cleaning robots using a representative site trial.
