STIHL KW-KM PowerSweep Attachment

The STIHL KW-KM PowerSweep is a cleanup attachment for the STIHL KombiSystem designed around rotating heavy-duty rubber flaps.

Instead of using bristles, the rubber paddles contact the surface and push material forward, making the attachment especially useful for stubborn debris and material that may be difficult to move with a conventional handheld blower.

What Can the STIHL PowerSweep Clean?

The KW-KM PowerSweep is designed for a variety of cleanup jobs, including:

• Caked dirt on roads and sidewalks
• Pebbles and loose gravel
• Sand on grassy turf
• Loose debris on suitable surfaces
• Standing or surface water
• Light snow on hard, flat areas

This gives the attachment useful applications throughout multiple seasons, from routine property cleanup to moving light winter accumulation.

Heavy-Duty Rubber Flaps

The defining feature of the KW-KM is its set of heavy-duty rubber flaps.

As the attachment operates, the rubber paddles sweep material forward across the surface. This design makes the PowerSweep particularly useful when the material needs to be physically pushed or rolled away rather than simply blown.

STIHL Gravel Sweeper

Customers often search for the KW-KM as a STIHL gravel sweeper because the attachment can move loose pebbles, gravel, and sand from suitable areas.

It can be especially useful where loose aggregate or small stones have migrated onto turf or across walkways and other cleanup areas.

STIHL Power Sweep for Dirt & Sidewalk Cleanup

The KW-KM is also designed to tackle caked dirt along roads, sidewalks, and similar surfaces.

The rubber sweeping action physically works across the surface, providing another option when loose material or stubborn buildup needs to be pushed away.

Move Water & Light Snow

The STIHL PowerSweep can also move water and light snow from hard, flat surfaces.

That can make it useful for seasonal cleanup on driveways, sidewalks, and other suitable areas where relatively light accumulation needs to be cleared.

STIHL PowerSweep vs. Power Broom

Shoppers frequently search for products like the KW-KM using terms such as STIHL power broom or power rake.

The KW-KM PowerSweep is specifically a rubber-flap sweeping attachment. It does not use the bristles associated with a brush-style sweeper.

If you are comparing STIHL sweeping attachments, choose based on the surface and type of material you need to move rather than relying on the generic “power broom” name alone.

STIHL PowerSweep vs. Bristle Brush

The main visible difference is the working surface:

• KW-KM PowerSweep: Uses heavy-duty rubber flaps.
• Bristle-style sweeping attachments: Use brush bristles.

The KW-KM's rubber paddles are designed for applications such as caked dirt, pebbles, sand, water, and light snow.

Part of the STIHL KombiSystem

The KW-KM is an attachment for the STIHL KombiSystem. The system allows one compatible KombiMotor powerhead to operate multiple task-specific attachments.

This makes the PowerSweep useful for customers who already own a compatible STIHL KombiMotor and want to expand the jobs their powerhead can perform.

The KombiMotor is not included with this listing.
