Kärcher B 50 W Bp Pack 115Ah D51 DOSE Rinse AutoFill Professional Walk-Behind Scrubber Dryer

Intelligent Floor Cleaning for Modern Commercial Environments

The Kärcher B 50 W Bp Pack 115Ah D51 DOSE Rinse AutoFill is an advanced battery-powered walk-behind scrubber dryer designed to maximise productivity, reduce water and detergent consumption, and simplify everyday floor cleaning. Featuring a 51 cm disc brush head, 50-litre clean and dirty water tanks, a powerful 115 Ah maintenance-free AGM battery, traction drive, and Kärcher's intelligent DOSE, AutoFill, and AutoRinse systems, this machine delivers outstanding cleaning performance while significantly reducing operator workload.

Designed for professional cleaning contractors, facilities management companies, hospitals, schools, retail premises, offices, hotels, and public buildings, the B 50 W Bp combines robust construction with smart technology to deliver reliable results day after day.

Long Runtime with Cordless Freedom

Powered by a 24V 115 Ah AGM battery, the B 50 W Bp provides extended operating times without the restrictions of trailing cables. Its integrated traction drive reduces operator effort, allowing large floor areas to be cleaned comfortably and efficiently while improving productivity throughout the working day.

Cordless operation also eliminates trip hazards and enables uninterrupted cleaning in busy commercial environments where flexibility is essential.

Advanced D51 Disc Brush Cleaning Performance

The machine features Kärcher's proven D51 disc brush head, delivering reliable and energy-efficient cleaning performance across a wide range of hard floor surfaces.

Combined with Kärcher's Eco!Flow system, which automatically adjusts water flow according to the machine's speed, the B 50 W Bp maintains consistent cleaning results while reducing unnecessary water consumption. Floors are left thoroughly cleaned with excellent water recovery, helping minimise slip hazards and allowing cleaned areas to return to service quickly.

Intelligent DOSE Cleaning Agent System

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

By accurately controlling detergent usage, the system helps:

• Reduce chemical waste
• Lower cleaning costs
• Deliver consistent cleaning results
• Simplify chemical changes through a closed-loop system
• Support more sustainable cleaning practices

Precise dosing also helps prevent overuse of cleaning chemicals while ensuring optimum cleaning performance every time.

AutoFill & AutoRinse for Faster Maintenance

The AutoFill system makes refilling the fresh water tank quick and effortless by automatically stopping the water flow when the tank reaches capacity. This prevents overfilling while reducing operator supervision during filling.

The AutoRinse system simplifies end-of-shift maintenance by automatically rinsing the dirty water tank without direct contact with contaminated water. This hygienic process reduces cleaning time, improves operator safety, and helps maintain the machine in peak working condition.

Durable Aluminium Components

Designed for demanding commercial use, the B 50 W Bp features a cast aluminium brush head and die-cast aluminium squeegee.

These heavy-duty components offer excellent durability and wear resistance while providing outstanding water recovery, even on textured flooring and when cleaning around tight corners. Their robust construction helps reduce downtime and extends the machine's service life.

Machine Connect App Integration

The Kärcher Machine Connect smartphone app provides operators and fleet managers with access to additional machine settings and useful operational information.

Using the app, users can:

• Adjust selected machine parameters
• Monitor machine performance
• Access maintenance guidance
• View troubleshooting support

Manage Kärcher Intelligent Key System (KIK) user permissions

This connected functionality helps improve productivity while simplifying machine management across multiple operators.

Kärcher Intelligent Key System (KIK)

The integrated Kärcher Intelligent Key System (KIK) allows businesses to assign different access rights and operating permissions for individual users.

• This helps:
• Reduce operator errors
• Standardise cleaning programmes
• Improve machine security
• Simplify staff training
• Protect equipment from incorrect operation

The system supports multiple languages, making it ideal for diverse commercial cleaning teams.

Compact Design with Excellent Manoeuvrability

Despite its generous tank capacity, the B 50 W Bp remains compact and highly manoeuvrable.

The machine provides excellent visibility during operation and is easy to navigate around shelving, furniture, corridors, and confined areas. Its compact footprint makes it particularly suitable for busy commercial environments where larger scrubber dryers may be less practical.
