Delivering a theoretical cleaning performance of up to 3,300 m² per hour, it is ideal for facilities requiring efficient, high-quality floor maintenance.

Perfect for contract cleaners, retail stores, healthcare facilities, schools, hotels, offices and public buildings, the B 50 W Bp has been engineered to maximise productivity while keeping operating costs under control.

Advanced R55 Roller Brush Technology

The R55 twin roller brush head combines high-speed scrubbing with an integrated pre-sweeping function, allowing operators to remove light debris while washing the floor in a single pass. Unlike conventional scrubber dryers, the roller brush system continuously lifts dirt and transports loose particles into the recovery system, helping reduce preparation time before cleaning.

The high brush speed and contact pressure provide outstanding cleaning performance on smooth, textured and safety flooring, while the parabolic squeegee leaves floors clean, dry and ready for immediate use.

Why Choose the R55 Roller Brush Over a Disc Brush?

While both Kärcher roller and disc scrubber dryers provide excellent cleaning performance, the R55 roller brush system offers several important advantages for facilities where debris, textured flooring and high traffic are part of everyday operations.

Advantages of the Roller Brush System

Integrated pre-sweeping function collects light debris such as dust, grit, hair and small particles while scrubbing, eliminating the need for separate sweeping in many applications.

Excellent performance on textured and safety flooring, maintaining consistent contact across uneven surfaces.

Superior cleaning of grout lines on tiled floors compared to conventional disc brushes.

High brush speed and contact pressure deliver outstanding mechanical cleaning action for removing stubborn dirt.

Lower water consumption when combined with Kärcher's Eco!Flow system, helping reduce running costs.

Excellent edge cleaning along walls, shelving and fixtures, reducing manual finishing work.

Faster overall cleaning by combining sweeping and scrubbing into one operation.

Reduced chemical usage, as the roller brushes provide effective mechanical cleaning with less reliance on detergents.

Floors dry quickly, allowing cleaned areas to return to service sooner and helping reduce slip hazards.

Recommended Applications for the Roller Brush System

The R55 roller brush is particularly well suited to environments where loose debris, textured flooring or intensive daily cleaning are common, including:

• Retail stores and supermarkets
• Shopping centres
• Warehouses and logistics facilities
• Hospitals and healthcare facilities
• Schools, colleges and universities

• Hotels and hospitality venues
• Food production and preparation areas

Entrances, reception areas and corridors

Public buildings

Safety flooring, textured vinyl, ceramic tiles and grout lines

For smooth, polished floors where routine maintenance cleaning is the priority, a disc brush machine remains an excellent option. However, businesses looking to maximise productivity and reduce preparation time will benefit from the versatility of Kärcher's R55 roller brush technology.

Long Battery Runtime with Traction Drive

Powered by a 24V 115 Ah maintenance-free AGM battery, the B 50 W Bp provides up to 2.5 hours of runtime, allowing operators to clean large commercial areas without interruption.

The integrated traction drive assists machine movement, reducing operator fatigue while making long cleaning sessions significantly more comfortable. The cordless design also removes the hazards and restrictions associated with power cables, improving safety and flexibility throughout busy commercial environments.

Intelligent DOSE Cleaning Agent System

The integrated DOSE detergent dosing system automatically dispenses the precise amount of cleaning chemical required during operation.

Benefits include:

• Accurate detergent dosing
• Reduced chemical consumption
• Lower operating costs
• Consistent cleaning performance
• Closed-loop detergent changes for improved operator safety
• Reduced environmental impact through less chemical waste

By ensuring the correct detergent concentration at all times, the DOSE system helps maintain professional cleaning standards while improving cost efficiency.

AutoFill & AutoRinse for Faster Maintenance

The AutoFill system automatically fills the fresh water tank and stops the water supply when the tank reaches capacity, preventing overfilling while saving valuable operator time.

The AutoRinse function automatically rinses the recovery tank without requiring direct contact with contaminated water, improving hygiene and reducing end-of-shift cleaning time. Together, these intelligent systems increase machine availability while simplifying routine maintenance.

Eco!Flow Intelligent Water Management

Kärcher's Eco!Flow system automatically adjusts water flow according to the machine's travelling speed.

• This provides:
• Consistent cleaning performance
• Reduced water consumption
• Improved efficiency around bends and corners
• Lower running costs
• Greater environmental sustainability

By delivering only the amount of water required, Eco!Flow helps maximise cleaning efficiency while reducing waste.

Durable Aluminium Construction

The B 50 W Bp has been built for demanding commercial use with a cast aluminium roller brush head and die-cast aluminium parabolic squeegee fitted with durable Linatex® suction lips.

• These heavy-duty components provide:
• Outstanding durability
• Excellent suction performance on structured flooring
• Reliable water recovery around tight corners
• Reduced maintenance requirements
• Longer machine service life

Their rugged construction helps minimise downtime while lowering the total cost of ownership.

Machine Connect Smart Connectivity

Using Kärcher's Machine Connect smartphone app, operators and fleet managers can access valuable operational information and additional machine settings.

Features include:

• Machine performance monitoring
• Maintenance guidance
• Troubleshooting support
• Adjustment of selected operating parameters

Kärcher Intelligent Key System (KIK) management

This connected technology helps improve fleet management, increase productivity and simplify machine maintenance.

Kärcher Intelligent Key System (KIK)

The integrated Kärcher Intelligent Key System (KIK) enables businesses to assign different user permissions for individual operators.

Key benefits include:

• Controlled machine access
• Reduced operator errors
• Standardised cleaning programmes
• Faster staff training
• Support for over 30 operating languages

This intelligent access system helps protect valuable equipment while ensuring consistent cleaning quality across multiple users.

Compact Design with Outstanding Manoeuvrability

Despite its generous 50-litre fresh and recovery tanks, the B 50 W Bp remains highly compact and easy to manoeuvre.

Excellent visibility, a tight turning radius and ergonomic controls make the machine ideal for navigating narrow aisles, shelving, furniture and other obstacles commonly found in commercial buildings.
