The Karcher KM 85/50 W Bp Vacuum Sweeper is a heavy-duty battery-powered walk-behind floor sweeper designed for demanding commercial and industrial environments where strong dust control, manoeuvrability and reliable everyday performance are essential.

Featuring a 615 mm floating main sweeping roller and 850 mm working width with one side brush, the KM 85/50 W Bp delivers a surface area performance of up to 3,825 m²/h. An optional second side brush increases the total working width to 1085 mm and productivity to an impressive 4,725 m²/h.

A powerful 24 V / 912 W traction motor provides controlled forward and reverse travel at speeds of up to 4.5 km/h, while the large 2.3 m² polyester filter and vacuum system provide excellent fine dust control for warehouses, factories, workshops and other demanding industrial floor cleaning applications.

Up to 4,725 m²/h Sweeping Performance

The Karcher KM 85/50 W Bp is designed to efficiently clean medium to large commercial and industrial floor areas.

In standard configuration with one side brush, the machine provides an 850 mm working width and up to 3,825 m²/h surface area performance.

Adding the optional second side brush increases the sweeping path to 1085 mm and productivity to up to 4,725 m²/h, providing an excellent option for facilities with larger open floor areas.

This combination of productivity and compact walk-behind design allows businesses to clean substantial areas efficiently without requiring a larger ride-on sweeper.

Powerful Forward and Reverse Traction Drive

A key advantage of the KM 85/50 W Bp is its 24 V / 912 W battery-powered traction system.

Both forward and reverse movement can be controlled directly from the push handle, making the machine easy to manoeuvre around shelving, machinery, vehicles and other obstacles.

The powered drive significantly reduces operator effort compared with manually propelled sweepers and provides a maximum working speed of 4.5 km/h.

With a climbing capacity of up to 15%, the machine is also capable of handling suitable ramps and gradients encountered around warehouses, loading areas and industrial facilities.

2.3 m² Professional Dust Filtration

For indoor industrial environments, effective dust control is critical.

The KM 85/50 W Bp features a large 2.3 m² polyester flat pleated filter combined with a powerful vacuum system to provide virtually dust-free sweeping.

The washable filter offers long service life and helps minimise ongoing replacement costs, while the dual scraper cleaning system assists in removing accumulated fine dust to maintain filtration and airflow performance.

This makes the machine particularly well suited to warehouse, factory and workshop floor sweeping, where controlling airborne dust is an important part of maintaining a cleaner working environment.

Floating Main Roller for Uneven Floors

The 615 mm floating main sweeping roller automatically adapts to variations in the floor surface.

Rather than relying on a fixed brush position, the floating design follows bumps, dips and uneven areas to maintain more consistent contact with the surface.

This is particularly valuable in industrial environments where concrete floors, loading areas and outdoor paved surfaces may not be perfectly level.

The result is reliable collection of fine dust, dirt and larger debris across a wider range of surface conditions.

Overhead Sweeping for High Dirt Pick-Up

The professional overhead sweeping principle is designed for strong dirt and debris collection across demanding commercial and industrial applications.

Material is efficiently swept from the floor and transferred into the large waste container, allowing the KM 85/50 W Bp to handle routine fine dust as well as heavier debris build-up.

This makes it suitable for environments ranging from relatively clean warehouse floors through to workshops, loading areas and industrial sites where larger quantities of dirt may accumulate.

50 L Mobile Waste Container

Collected material is stored in a generous 50 litre mobile waste container.

Integrated castors allow the container to be removed and rolled to the disposal point rather than requiring the operator to carry a heavy load of collected dirt and debris.

This practical design simplifies emptying and is particularly useful when the machine is used in larger facilities where substantial quantities of debris may be collected during each cleaning cycle.

Compact Enough for Standard Doorways

Despite its heavy-duty construction and professional sweeping capability, the KM 85/50 W Bp maintains excellent manoeuvrability.

In its standard one-side-brush configuration, the machine's 850 mm working width allows it to pass through standard 900 mm doorways, making it suitable for facilities containing multiple rooms, workshops, storage areas and internal access points.

Large wheels provide smooth travel across rough and uneven surfaces, while the compact walk-behind configuration allows the operator to manoeuvre through congested working environments where a ride-on sweeper may be impractical.

Built for Demanding Industrial Environments

The KM 85/50 W Bp features a robust double-walled frame designed to withstand the demands of regular professional use.

The side brush incorporates a protective swerving mechanism that allows it to move away when contacting walls or obstacles, helping protect both the brush and machine from accidental impact damage.

A disc brake provides secure stopping, while the machine's large wheels improve stability and travel over uneven surfaces.

These features make the KM 85/50 W Bp particularly well suited to demanding workshops, warehouses, factories and industrial sites.

Sweeping Damp and Wet Surfaces

The vacuum system incorporates suction volume regulation, allowing the operator to adjust suction when sweeping damp or wet surfaces.

This provides additional versatility for outdoor areas, loading zones, car parks and other environments where surface conditions may vary throughout the day.

Easy Operation and Maintenance

The KM 85/50 W Bp is designed to keep everyday operation and servicing straightforward.

The main roller and side brush can be switched on and off using simple controls, while a battery indicator allows the operator to monitor remaining capacity.

An integrated hour counter helps businesses track operating time and schedule preventative maintenance at appropriate intervals.

The main sweeping roller and filter can also be replaced without tools, reducing the time required for routine maintenance and wear-component replacement.

Karcher Home Base System

The integrated Karcher Home Base system provides convenient mounting and storage options for additional cleaning tools and accessories.

This allows operators to carry frequently required equipment directly on the sweeper, helping improve productivity when completing general facility and property maintenance tasks.

Ideal Applications

The Karcher KM 85/50 W Bp is ideal for:

• Warehouses
• Distribution centres
• Logistics facilities
• Factory floors
• Manufacturing facilities
• Mechanical workshops
• Automotive workshops
• Industrial sites
• Loading docks and loading areas
• Car parks
• Service facilities
• Commercial properties
• Facility management
• Professional contract cleaning
• Uneven concrete floors
• Indoor hard floors
• Outdoor paved areas
• Areas with heavier dirt and debris accumulation

Its combination of up to 4,725 m²/h productivity, 2.3 m² dust filtration, forward and reverse traction drive, floating main roller and 50 litre waste capacity makes it an excellent choice for businesses requiring a substantial professional walk-behind sweeper without moving to a ride-on machine.

Heavy-Duty Walk-Behind Sweeping Performance

The KM 85/50 W Bp sits above smaller commercial walk-behind sweepers by providing increased working width, larger filtration capacity, a bigger waste container and a more powerful traction system.

Its floating main roller and robust double-walled construction also make it particularly suitable for harsher industrial environments and facilities with uneven flooring.

For businesses cleaning warehouses, factories, workshops and loading areas on a regular basis, the KM 85/50 W Bp provides an excellent balance between ride-on sweeper capability and walk-behind manoeuvrability.
