Automate Repetitive Commercial Floor Scrubbing

Traditional commercial floor scrubbing requires an employee to continuously walk behind or ride on the machine.

The KIRA B50 changes that.

Once cleaning routes are configured, the robot can perform routine floor cleaning autonomously while employees concentrate on work that still requires people.

That can include:

  • Restrooms
  • Disinfection
  • Touch-point cleaning
  • Trash removal
  • Spot cleaning
  • Detail cleaning
  • Patient or guest areas
  • High-priority EVS tasks

For facilities facing labor shortages, employee turnover, increasing wages, or expanding cleaning requirements, autonomous floor care can help increase the amount of square footage each cleaning team can effectively maintain.

The goal isn't simply to replace a floor scrubber. It's to automate the labor required to continuously operate one.


Pre-Sweep, Scrub & Recover Water in a Single Pass

The KIRA B50 is designed to do more than simply scrub the floor.

Its cylindrical roller-brush cleaning system incorporates automatic pre-sweeping, allowing the machine to collect coarse debris while scrubbing.

The integrated side brush transports debris directly into the cleaning channel and improves cleaning along edges.

That means the robot can perform multiple floor-care functions during the same cleaning mission:

Pre-Sweep → Scrub → Recover Dirty Water

Combining these operations can reduce the amount of manual preparation and follow-up required from cleaning employees.


Up to 25,457 Square Feet Per Hour

Kärcher rates the platform for theoretical autonomous productivity of up to:

25,457 ft²/hr

Coverage per tank filling is approximately 19,698 square feet.

Actual productivity will vary depending on:

  • Facility layout
  • Obstacles
  • Cleaning speed
  • Route complexity
  • Soil level
  • Water settings
  • Cleaning parameters

The important difference is that this square footage can be cleaned without an employee continuously driving the scrubber.


22-Inch Commercial Scrubbing Path

The KIRA B50 features a 22-inch brush working width with a 29.5-inch vacuum working width.

Its cylindrical roller brushes operate at up to 1,200 RPM, providing strong mechanical cleaning action while automatic pre-sweeping helps capture larger debris.

This makes the KIRA B50 particularly effective for commercial environments requiring frequent routine hard-floor maintenance.


360° Autonomous Navigation & Environmental Awareness

The KIRA B50 uses a sophisticated sensor system to continuously understand its surroundings.

Kärcher's autonomous platform provides:

  • 360° environmental detection
  • Lateral monitoring
  • Obstacle detection
  • Fall detection
  • Person detection
  • Autonomous obstacle avoidance
  • Intelligent free-travel maneuvers when blocked

Rather than simply stopping every time something changes in the environment, the robot is designed to intelligently navigate around obstacles whenever conditions allow.


Safety-Certified for Public Areas

Autonomous equipment operating around employees, patients, customers, students, or visitors requires a high level of safety.

The KIRA platform is safety-certified according to IEC 63327 and designed for operation in high-traffic public environments.

The system provides contactless detection of:

  • People
  • Obstacles
  • Drop-offs
  • Environmental hazards

This makes the KIRA B50 well suited for occupied commercial facilities where autonomous equipment may encounter changing conditions throughout its cleaning route.


Teach & Repeat for Precise Cleaning Routes

For complex or confined areas, operators can manually teach the robot the exact route they want it to follow.

The Teach & Repeat functionality allows the KIRA B50 to learn a precise route and then reproduce it autonomously.

This is especially useful for:

  • Narrow corridors
  • Complex layouts
  • Defined cleaning lanes
  • Areas with fixed equipment
  • Spaces requiring precise navigation

Smart Fill for Large Open Spaces

Large open areas don't necessarily need to be manually mapped lane by lane.

Kärcher's Smart Fill functionality allows autonomous route planning for larger open spaces.

This can simplify deployment in areas such as:

  • Warehouses
  • Airports
  • Manufacturing plants
  • Grocery stores
  • Retail spaces
  • Convention facilities
  • Large corridors

Customizable Autonomous Cleaning Routes

After routes have been created, operators can modify cleaning parameters and establish specialized zones.

The system supports features including:

  • No-go zones
  • No-clean zones
  • Speed filters
  • Horn zones
  • Interaction zones
  • Interlinked cleaning routes
  • Individual cleaning parameters

This allows the robot to adapt to the way your facility actually operates rather than requiring the facility to adapt to the robot.


14.5-Gallon Fresh & Recovery Tanks

The KIRA B50 incorporates:

  • 14.5-gallon fresh-water tank
  • 14.5-gallon recovery tank
  • 1.3-gallon detergent tank
  • 0.5-gallon debris hopper

These capacities support extended autonomous cleaning across medium and large commercial spaces.


Intelligent Water & Detergent Management

The KIRA B50 uses speed-dependent water dosing, helping the machine adjust resource usage based on operating conditions.

It also supports Kärcher's DOSE detergent dosing system for controlled chemical application.

This helps facilities manage:

  • Water consumption
  • Detergent consumption
  • Cleaning consistency
  • Operating costs

Approximately 4 Hours of Battery Runtime

The KIRA B50 platform provides approximately four hours of battery runtime.

Maximum charging time is approximately 5.8 hours.

With the optional docking station, however, facilities can take autonomy considerably further.


Optional Fully Autonomous Docking Station

Add the optional Kärcher KIRA B50 Docking Station to create a more hands-off autonomous cleaning system.

The docking station allows the robot to automatically:

  • Recharge its battery
  • Refill the fresh-water tank
  • Drain the dirty-water tank
  • Rinse the dirty-water tank

Kärcher specifically designed the docking system to replenish the resources required by the robot without an employee manually servicing the machine between cleaning cycles.

KIRA B50 Docking Station

Part Number: 2.042-000.0
Price: $3,195.00

For facilities seeking the highest level of automation, Automation Hub strongly recommends evaluating the docking station as part of the initial deployment.


Manual Operation When You Need It

Autonomous operation doesn't eliminate flexibility.

The KIRA B50 can also be operated manually.

This allows employees to use the machine for:

  • Spot cleaning
  • Unplanned spills
  • Areas outside programmed routes
  • One-time cleaning
  • Direct operator-controlled tasks

You therefore get both an autonomous robot and a manually operable commercial floor scrubber in one platform.


Remote Monitoring & Cleaning Reports

Facility managers can remotely access robot information through Kärcher's equipment-management platform.

Available information includes:

  • Cleaning reports
  • Robot status
  • Notifications
  • Operating information
  • Fault information
  • Mobile-device status messages

This provides something conventional floor scrubbing often cannot:

Documented Cleaning Performance

Instead of simply assuming an area was cleaned, managers can gain greater visibility into autonomous cleaning activity.


Scheduled Autonomous Cleaning

The KIRA platform includes calendar functionality for scheduling cleaning tasks.

Facilities can build routine autonomous floor cleaning into their daily operations instead of waiting for an employee to become available to operate a scrubber.

This can be particularly useful for:

  • Overnight cleaning
  • Low-traffic periods
  • Between shifts
  • Recurring corridor cleaning
  • Scheduled common-area maintenance

Designed for Medium to Large Commercial Facilities

The KIRA B50 is particularly well suited for medium and large hard-floor environments.

Hospitals & Healthcare Facilities
